Getting Session information using the Python Module for VMware Horizon with filtering

Since Horizon 8 it is possible to retrieve session information using the REST api’s. In the python module for Horizon I have translated that functionality to the get_sessions function.

import requests, getpass, urllib, json

import vmware_horizon

requests.packages.urllib3.disable_warnings()
url = input("URL\n")

username = input("Username\n")

domain = input("Domain\n")

pw = getpass.getpass()

hvconnectionobj = vmware_horizon.Connection(username = username,domain = domain,password = pw,url = url)
hvconnectionobj.hv_connect()
print("connected")

inventory=vmware_horizon.Inventory(url=hvconnectionobj.url, access_token=hvconnectionobj.access_token)
sessions = inventory.get_sessions()
for i in sessions:
    for ii in i:
        print(ii, '=', i[ii] )


end=hvconnectionobj.hv_disconnect()
print(end)

You see a lot of the information is returned using an id but there are plenty of functions that you can use to get the readable information for those.

Since Horizon 2103 VMware has added an option use filtering when getting session information. In the example above you can see that I have a connected and a disconnected session, let’s get the connected one. First I create the filter.

filter = {}
filter["type"] = "And"
filter["filters"] = []
filter1={}

filter1["type"] = "Equals"
filter1["name"] = "session_state"
filter1["value"] = "CONNECTED"

filter["filters"].append(filter1)

Next I run the action with the filter argument.

sessions = inventory.get_sessions(filter=filter)

And now you see only the connected one is returned

And when I switch to disconnected

The new python module has been pushed to github together with example scripts for retrieving all sessions and with filtering.

vCheck for Horizon : small updates & running it (automatically) from ControlUp

Remark : as of the time I was writing this article the vCheck for Horizon  sba hasn’t been published yet. Contact me if you want me to send you the xml file.

Last week I have been doing a few small updates to the vCheck for Horizon. The file with the encrypted password is now replaced by an xml file that holds all of the credentials and is usable directly for Horizon connections. I have been using this for my blog posts and demo’s for a while already. Also I have renamed the security & composer plugins by default to old as those have been deprecated and I don’t want to have them active by default anymore. Further I have done some small changes to other plugins.

Creating the xml file

Running the vCheck from horizon

But but wasn’t the vCheck all about running it automagically?

Creating the xml file

this can be easily done like this:

$creds = get-credential
$creds | export-clixml filename.xml

as you might have seen during my demo’s you can use this $creds object to make a connection.

$creds = import-clixml filename.xml
$server = connect-hvserver connectionserver.fq.dn -credential $creds

Make sure to save this file to a good location and edit the “00 Connection Plugin for View.ps1” file with the proper location. I haven’t completely removed the old ways yet, they’re still partially there.

Running the vCheck script from ControlUp

Before everything else: make sure the machine that will run the vCheck has the latest version of PowerCLI installed. Download it here, and unpack the modules to “C:\Program Files\WindowsPowerShell\Modules” like this:

There are several things that I needed to do before I was able to run the vCheck from the ControlUp console or as an Automated Action (more on this later!). First I needed a way of providing credentials to the script. This is something I do using the Create Credentials for Horizon Scripts script action. If you already use some of the other Horizon related sba’s or the Horizon Sync script you might already have this configured. What it essentially does is creating an xml file as described above in a folder dedicated for ControlUp and usable by the service account that ran the sba. More on this can be found here.

Next was a way to get the vCheck itself. I do this by downloading it from github and unpack the zip file to C:\ProgramData\ControlUp\ScriptSupport\vCheck-HorizonView-master if downloads from the interwebz aren’t available you can download and unzip it yourself, just make sure it looks like this:

Next would be all the settings for email, connection server etcetera. This is all done trough the Script Action Arguments. WHat technically happens is that the Script Action removes both the globalvariables.ps1 and the “00 Connection Plugin for View.ps1” files and recreates them with those settings.

Once you have downloaded the vCheck you can run it manually so right click any random machine and select the vCheck for Horizon.

and fill in all the details you need. If you set the Send Email to false there is no need for the rest of the info.

Once you see this screen the script has completed, make sure to read the last line for the correct status and where you saved to file to.

And on my d:\ I see the file (and some others I used for testing)

And even better I received it in my mail as well

But but wasn’t the vCheck all about running it automagically?

Well yes it is and you can do that starting with version 8.5 that we have announced today! For now it will need to run hourly but in future releases we can also do this once a day. What you need to do for this is first change the default for the script action. Select that sba and hot the modify button.

Under settings you can keep the execution context as console (this will use the monitor when you run it as an automated action) or select other machine to pick a scripting server. Also make sure to select a shared credential that has a Horizon credentials file created on this machine.

Now go to the arguments tab and edit the default settings to set them to what you need.

Before:

Editing the first one

and done, press ok after this.

Now click finalize so the monitors can also use them and go trough all the steps ( no need to share with the community) an dmake sure the ControlUp Monitors have the permissions to run the sba.

Next we go to triggers > add trigger and select the new type: scheduled and click next

select the hourly schedule and a proper start and end time and click next

On the filter criteria make sure that you set the name to a single machine, otherwise the script will run for all machines in your environment. I recommend the same machine you used for the execution context. Keep in mind that the schedule functions just like any other trigger so you need to filter properly to what machine it applies and if you don’t it will apply to all of them.

You can select the folder this machine resides in and/or select a schedule to run the script in.

At the follow-up actions click add and select run an action from the pulldown menu. Under script name select the vCheck for Horizon, click ok and next

Make sure to create a clear name and click finish

The html should automatically end up in the export location and in your email.

 

Creating a RDS farm using the Python module for VMware Horizon

One of the goals and hopes I had with my 100DaysOfCode (I am writing this on day 100!) was that the Horizon REST api’s to create desktop pools and RDS farms would have been available at the end. Only half of that came out and with Horizon 8 2103 we can finally create a RDS farm using those rest api’s. I have decided to add this to the Python module based on a dictionary that the user sends to the new_farm method. I could still add a fully fetched function but that would require a lot of arguments and using **kwargs is an option but than the user would still need to find out what to use.

First I will need to know what json data I actually need, let’s have a look at the api explorer page to get a grip on this

As said I send a dictionary to the method so let’s import data into a dict called data and I will print it to screen. The dictionary needs to follow this specific order of lines so that’s why a json is very useful to start with.

with open('/mnt/d/homelab/farm.json') as f:
    data = json.load(f)

As you can see in both the json and the output there’s a lot of things we can change and some things that we need to change lik id’s for all the components like vCenter, base vm, base snapshot and more. First I need the access_group_id this can be retreived using the get_local_access_groups method. For all of these I will also set the variable in the dictionary that we need.

local_access_group = next(item for item in (config.get_local_access_groups()) if item["name"] == "Root")
data["access_group_id"] = local_access_group["id"]

Than it’s time for the Instant Clone Admin id

ic_domain_account = next(item for item in (config.get_ic_domain_accounts()) if item["username"] == "administrator")
data["automated_farm_settings"]["customization_settings"]["instant_clone_domain_account_id"] = ic_domain_account["id"]

For the basevm and snapshot id’s I used the same method but a bit differently as I had already used this method in another script

vcenters = monitor.virtual_centers()
vcid = vcenters[0]["id"]
dcs = external.get_datacenters(vcenter_id=vcid)
dcid = dcs[0]["id"]

base_vms = external.get_base_vms(vcenter_id=vcid,datacenter_id=dcid,filter_incompatible_vms=True)

base_vm = next(item for item in base_vms if item["name"] == "srv2019-p1-2020-10-13-08-44")
basevmid=base_vm["id"]

base_snapshots = external.get_base_snapshots(vcenter_id=vcid, base_vm_id=base_vm["id"])

base_snapshot = next(item for item in base_snapshots if item["name"] == "Created by Packer")

snapid=base_snapshot["id"]
data["automated_farm_settings"]["provisioning_settings"]["base_snapshot_id"] = snapid
data["automated_farm_settings"]["provisioning_settings"]["parent_vm_id"] = basevmid

Host or cluster id

host_or_clusters = external.get_hosts_or_clusters(vcenter_id=vcid, datacenter_id=dcid)
for i in host_or_clusters:
    if (i["details"]["name"]) == "Cluster_Pod1":
        host_or_cluster = i
data["automated_farm_settings"]["provisioning_settings"]["host_or_cluster_id"] = host_or_cluster["id"]

Resource Pool

resource_pools = external.get_resource_pools(vcenter_id=vcid, host_or_cluster_id=host_or_cluster["id"])
for i in resource_pools:
    # print(i)
    if (i["type"] == "CLUSTER"):
        resource_pool = i
data["automated_farm_settings"]["provisioning_settings"]["resource_pool_id"] = resource_pool["id"]

VM folder again is a bit different as I have to get the id from one of the children objects

vm_folders = external.get_vm_folders(vcenter_id=vcid, datacenter_id=dcid)
for i in vm_folders:
    children=(i["children"])
    for ii in children:
        # print(ii["name"])
        if (ii["name"]) == "Pod1":
            vm_folder = i
data["automated_farm_settings"]["provisioning_settings"]["vm_folder_id"] = vm_folder["id"]

Datacenter and vcenter id’s I already had to grab for the base vm and base snapshot so I can just add them

data["automated_farm_settings"]["provisioning_settings"]["datacenter_id"] = dcid
data["automated_farm_settings"]["vcenter_id"] = vcid

Datastores is a bit more funky as there can be multiple so I needed to create a list first and than populate that based on the name of the datastores I have.

datastore_list = []
datastores = external.get_datastores(vcenter_id=vcid, host_or_cluster_id=host_or_cluster["id"])
for i in datastores:
    # print(i)
    if (i["name"] == "VDI-500") or i["name"] == "VDI-200":
        ds = {}
        ds["datastore_id"] = i["id"]
        datastore_list.append(ds)
data["automated_farm_settings"]["storage_settings"]["datastores"] = datastore_list

For my final script I put them in a bit different order and I decided to change a whole lot more options but if you have your json perfected this shouldn’t always be required. Also take note that for true/false in the json that I use the True/False from python.

end=hvconnectionobj.hv_disconnect()
print(end)

How does this look? Actually you don’t see a lot happening but the farm will have been created

As always the script can be found on my github in the examples folder together with the json file.

With this I am closing my 100DaysOfCode challenge but I pledge to keep maintaining the python module and I will extend it when new REST api calls arrive for VMware Horizon.

The VMware Labs flings monthly for March 2021 – New Website

A day late but never late than never, this is your monthly overview with all the latest and greatest VMware flings. The flings site received a new fresh look head out to https://flings.vmware.com to have a look yourself. I am not sure if the (are they new?) tags for updated or new flings are okay yet as one has been marked updated but it seems to be new while one new one I could find a blog post for from last month but I missed it for my overview, not sure what happened there. Overall I see four new flings and ten received an update.

Configuration Wizard for Nuance PowerMic

Nuance PowerMics are the leading dictation device used in Healthcare today.
This handy standalone Fling will assist in determining the optimal PowerMic configuration for a specific customer environment.

To determine the configuration that works best for you, we need to know a few details about the customer environment:

  • Endpoint type
  • Endpoint vendor
  • Endpoint operating system
  • Single/nested mode
  • Horizon protocol

The PowerMic Configuration Wizard will then provide the specific settings for optimal PowerMic performance and accuracy in the customers environment.

vRealize Automation Code Stream CLI

vRealize Automation Code Stream CLI is a command line tool written in Go to interact with the vRealize Automation Code Stream APIs. This Fling is written to help automate Code Stream and provide a simple way to migrate content between Code Stream instances and projects.

  • Import and Export Code Stream artefacts such as Pipelines, Variables, Endpoints
  • Perform CRUD operations on Code Stream artefacts such as Pipelines, Variables, Endpoints
  • Trigger Executions of Pipelines

Hillview: Distributed Data Visualization

Hillview is a simple cloud-based spreadsheet program for browsing large data collections. The data manipulated is read-only. Users can sort, find, filter, transform, query, zoom-in/out, and chart data. Operations are performed using direct manipulation in the GUI. Hillview is designed to work on very large data sets (billions of rows). Hillview can import data from a variety of sources: CSV files, ORC files, Parquet files, databases, parallel databases; new connectors can be added with relatively little effort. Hillview takes advantage of all the cores of the worker machines for fast visualizations.

Hillview is a distributed system, composed of two pieces:

  • A distributed set of one or many workers, which should be installed close to the data (e.g., on the machines that host the data).
  • A front-end service that runs a web server and aggregates data from all workers.

The source code of Hillview is available as an open-source project with an Apache-2 license from Hillview’s github repository. For any questions, feature requests or bug reports please file an issue on github.

SDDC Import/Export for VMware Cloud on AWS

The SDDC Import/Export for VMware Cloud on AWS tool enables you to save and restore your VMware Cloud on AWS (VMC) Software-Defined Data Center (SDDC) networking and security configuration.

There are many situations when customers want to migrate from an existing SDDC to a different one. While HCX addresses the data migration challenge, this tool offers customers the ability to copy the configuration from a source to a destination SDDC.

A few example migration scenarios are:

  • SDDC to SDDC migration from bare-metal (i3) to a different bare-metal type (i3en)
  • SDDC to SDDC migration from VMware-based org to an AWS-based org
  • SDDC to SDDC migration from region (i.e. London) to a different region (i.e. Dublin).

Other use cases are:

  • Backups – save the entire SDDC configuration
  • Lab purposes – customers or partners might want to deploy SDDCs with a pre-populated configuration.
  • DR purposes – deploy a pre-populated configuration in conjunction with VMware Site Recovery or VMware Cloud Disaster Recovery

Detailed instructions can be found on the Instructions tab, in the README.md included in the Zip file or on Patrick’s blog (http://www.patrickkremer.com/sddc-import-export/).

Details about the use cases and origins of the project can be found on Nico’s blog (https://nicovibert.com/2021/02/08/fling-sddc-import-export-for-vmware-cloud-on-aws/).

Updates

Workspace ONE Mobileconfig Importer

The Workspace ONE mobileconfig Importer gives you the ability to import existing mobileconfig files directly into a Workspace ONE UEM environment as a Custom Settings profile, import app preference plist files in order to created managed preference profiles, and to create new Custom Settings profiles from scratch. When importing existing configuration profiles, the tool will attempt to separate each PayloadContent dictionary into a separate payload for the Workspace ONE profile.

The Horizon Cloud Pod Architecture Tools mainly acts as a wrapper around the lmvutil for Horizon Cloud Pod Archtitecture.

Changelog

Version 1.1

Based on the customer requests, have added few more command line options for CSV reports generation and AD LDS data cleanup.

What’s New:

Adds support to cleanup stale global local entitlement assignments from ADAM DB.

  • Global AD LDS Command:
    adlds-analyzer.cmd –resolve-localpool-ga
  • Scans the cloud pod database and resolves the stale entries of local pool global assignments.
    Note: This resolves deleted local pool conflicts of current pod only. If dashboard session data load error or session search fails in a different pod, a scan and resolve has to be executed in that pod.
  • List of new commands added to Local AD LDS:
    adlds-analyzer.cmd –export-machine
  • All machine data exported as CSV file. Compatibility: Horizon 7.10 and above, 8.x
    adlds-analyzer.cmd –export-machine -pool=”DesktopPool1,DesktopPool2″
  • All machine data exported as CSV file. Use -pool= to filter machines by desktop pool name. Compatibility: Horizon 7.10 and above, 8.x
  • Spaces are not allowed in -pool= optional argument.
    adlds-analyzer.cmd –export-session
  • All local sessions data exported as CSV file. Compatibility: Horizon 7.10 and above, 8.x
    adlds-analyzer.cmd –export-session -pool=”PoolName1,PoolName2″ -farm=”FarmName1,FarmName2″
  • All local session data exported as CSV file. Use -pool= to filter sessions by desktop pool name. -farm= filter sessions by RDS farm name. Compatibility: Horizon 7.10 and above, 8.x
  • Spaces are not allowed in -pool= and -farm= optional argument.
    adlds-analyzer.cmd –check-apps-integrity
  • Scans and lists the stale application icons in local ADLDS instance.

DoD Security Technical Implementation Guide(STIG) ESXi VIB

The DoD Security Technical Implementation Guide (‘STIG’) ESXi VIB is a Fling that provides a custom VMware-signed ESXi vSphere Installation Bundle (‘VIB’) to assist in remediating Defense Information Systems Agency STIG controls for ESXi. This VIB has been developed to help customers rapidly implement the more challenging aspects of the vSphere STIG. These include the fact that installation is time consuming and must be done manually on the ESXi hosts. In certain cases, it may require complex scripting, or even development of an in-house VIB that would not be officially digitally signed by VMware (and therefore would not be deployed as a normal patch would). The need for a VMware-signed VIB is due to the system level files that are to be replaced. These files cannot be modified at a community supported acceptance level. The use of the VMware-signed STIG VIB provides customers the following benefits:

  • The ability to use vSphere Update Manager (‘VUM’) to quickly deploy the VIB to ESXi hosts (you cannot do this with a customer created VIB)
  • The ability to use VUM to quickly check if all ESXi hosts have the STIG VIB installed and therefore are also in compliance
  • No need to manually replace and copy files directly on each ESXi host in your environment
  • No need to create complex shell scripts that run each time ESXi boots to re-apply settings

Changelog

Update March 2021

  • New ESXi 7.0 STIG VIB release
  • Updated sshd_config file to meet the ESXi 7.0 Draft STIG which is also now the default config in 7.0 U2 with the exception of permitting root user logins.
  • Removed /etc/vmware/welcome file from VIB since it can be configured via the UI or PowerCLI now with issue.
  • Draft ESXi content can be found here: https://github.com/vmware/dod-compliance-and-automation/tree/master/vsphere/7.0/docs
  • See the updated Overview and Installation guide included in the download.

VMware OS Optimization Tool

No comments needed, just use the OS Optimization Tool when creating your golden images!

Changelog

March 2021, b2002

  • Fixed issue where the theme file was being updated by a Generalize task and the previously selected optimizations including wallpaper color were being lost.
  • The administrator username used during Generalize was not getting passed through properly to the unattend answer file. This resulted in a mismatch when using some languages versions of Windows.
  • Removed legacy code GPO Policy corruption
  • Removed CMD.exe box that displayed at logon.
  • Windows Store Apps were not being removed properly on Windows 10 version 20H2. Fixed the optimizations to cope with the differences introduced in this version.

Optimizations

Changed step Block all consumer Microsoft account user authentication to be unselected by default. When disabled this was causing failures to login to Edge and Windows store.

Changed the step Turn off Thumbnail Previews in File Explorer to be unselected by default. This was causing no thumbnails to show for store apps in search results.

Windows Update

On Non-Enterprise editions of Windows 10, KB4023057 installs a new application called Microsoft Update Health Tools: https://support.microsoft.com/en-us/topic/kb4023057-update-for-windows-10-update-service-components-fccad0ca-dc10-2e46-9ed1-7e392450fb3a. Added logic to ensure that the Windows Update Medic Service is disabled including after re-enabling and disabling Windows Updates using the Update tab.

Templates

Windows 8 and 8.1 templates have been removed from the list of built-in templates. To optimize these versions of Windows, use the separate download for version b1130.

Removed old Windows 10 templates from the Public Templates repository:

  • Windows 10 1809-2004-Server 2019
  • Windows 10 1507-1803-Server 2016

January 2021, b2001 Bug Fixes

  • All optimization entries have been added back into the main user template. This allows manual tuning and selection of all optimizations.
  • Fixed two hardware acceleration selections were not previously controlled by the Common Option for Visual Effect to disable hardware acceleration.

Optimize

  • During an Optimize, the optimization selections are automatically exported to a default json file (%ProgramData%\VMware\OSOT\OptimizedTemplateData.json).

Analyze

  • When an Analyze is run, if the default json file exists (meaning that this image has already been optimized), this is imported and used to select the optimizations and the Common Options selections with the previous choices.
  • If the default selections are required, on subsequent runs of the OS Optimization Tool, delete the default json file, relaunch the tool and run Analyze.

Command Line

  • The OptimizedTemplateData.json file can also be used from the command line with the -applyoptimization parameter.

Optimizations

  • Changed entries for Hyper-V services to not be selected by default. These services are required for VMs deployed onto Azure. Windows installation sets these to manual (trigger) so these so not cause any overhead on vSphere, when left with the default setting.

Powercli script to assign a dedicated Horizon machine to multiple users

Yesterday Robin Stolpe again reached out that he was having issues assigning multiple accounts to the same dedicated machine. He couldn’t get this running with the vmware.hv.helper and looking that with how it is implemented now it will probably never work. I decided to put together some of the functions I have used for ControlUp script based actions and some of my other work to put together the following script (that can be found on Github here.)

$Services1.Machine.Machine_assignUsers($machineid, $useridlist)

So first I have 3 functions to get the Pool, the machine and users. With a foreach on the $Targetusers list I create a list of the userid’s that is required to use for the Machine_assignUsers function of the machine service.

Powercli script to (forcefully) log off Horizon users

A long time ago in a galaxy far far away I wrote this blog post to log a user off from their vdi session. Today I got an inquiry from Robin Stolpe that he was trying to make it a script with arguments instead if the menu’s but was having some issues with that. This gave me the chance to make it a bit nicer of a script with the option to user username/domain/password as credentials but also a credentialfile , optional forcefully logging off the users and with Robin’s requirements of being able to provide the exact username and the machine that user is working on.

The script can be ran like this:

D:\GIT\Scripts\logoff_user.ps1 -Credentialfile "D:\homelab\creds.xml" -TargetUser "loft.lab\m_wouter" -TargetMachine "lp-001.loft.lab" -ConnectionServerFQDN loftcbr01.loft.lab

or with credentials and the -force parameter

D:\GIT\Scripts\logoff_user.ps1 -TargetUser "loft.lab\m_wouter" -TargetMachine "lp-001.loft.lab" -ConnectionServerFQDN loftcbr01.loft.lab -Username m_wouter -domain loft.lab -password "HAHAHAHA" -force

Now let’s have a look how the script is build.

So I started with the parameters and for that I included 2 parameter sets so you can either choose to have the separate credentials or to use a credentials file.

    ParameterSetName="separatecredentials",
    HelpMessage='Password in plain text' )]
    [string] $Password,

    [Parameter(Mandatory=$true,  HelpMessage='FQDN of the connectionserver' )]
    [ValidateNotNullOrEmpty()]
    [string] $ConnectionServerFQDN,

    [Parameter(Mandatory=$false,
    ParameterSetName="credsfile",
    HelpMessage='Path to credentials xml file' )]
    [ValidateNotNullOrEmpty()]
    [string] $Credentialfile,

    [Parameter(Mandatory=$false, HelpMessage='Synchronise the local site only' )]
    [switch] $Force,

    [Parameter(Mandatory=$false,  HelpMessage='username of the user to logoff (domain\user i.e. loft.lab\user1')]
    [ValidateNotNullOrEmpty()]
    [string] $TargetUser,

    [Parameter(Mandatory=$false, HelpMessage='dns name of the machine the user is on i.d. lp-002.loft.lab')]
  [string] $TargetMachine
)

Than I check if a credential file was supplied and if I can actually import it

if($Credentialfile -and ((test-path $Credentialfile) -eq $true)){
    try{
        write-host "Using credentialsfile"
        $credentials=Import-Clixml $Credentialfile
        $username=($credentials.username).split("\")[1]
        $domain=($credentials.username).split("\")[0]
        $secpw=$credentials.password
        $BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($secpw)
        $password = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)
    }
    catch{
        write-error -Message "Error importing credentials"
        break
    }
}
elseif($Credentials -and ((test-path $credentials) -eq $false)){
    write-error "Invalid Path to credentials file"
}
elseif($username -and $Domain -and $Password){
    write-host "Using separate credentials"
}

The file doesn’t exist:

Or an error importing the xml (duh, what do you think what happoens when you use a json instead of xml, fool!)

Then it’s a matter of logging in, performing a query and checking if there’s really a session for this user. As you can see I am using machineOrRDSServerDNS so it should also work for RDS sessions.

$hvserver1=connect-hvserver $ConnectionServerFQDN -user $username -domain $domain -password $password
$Services1= $hvServer1.ExtensionData

$queryService = New-Object VMware.Hv.QueryServiceService
$sessionfilterspec = New-Object VMware.Hv.QueryDefinition
$sessionfilterspec.queryEntityType = 'SessionLocalSummaryView'
$sessionfilter1= New-Object VMware.Hv.QueryFilterEquals
$sessionfilter1.membername='namesData.userName'
$sessionfilter1.value=$TargetUser
$sessionfilter2= New-Object VMware.Hv.QueryFilterEquals
$sessionfilter2.membername='namesData.machineOrRDSServerDNS'
$sessionfilter2.value=$TargetMachine
$sessionfilter=new-object vmware.hv.QueryFilterAnd
$sessionfilter.filters=@($sessionfilter1, $sessionfilter2)
$sessionfilterspec.filter=$sessionfilter
$session=($queryService.QueryService_Create($Services1, $sessionfilterspec)).results
$queryService.QueryService_DeleteAll($services1)
if($session.count -eq 0){
    write-host "No session found for $targetuser on $targetmachine"
    break
}

And last but not least logging the user of with or without the -force option

if($Force){
    write-host "Forcefully logging off $targetUser from $targetmachine"
    $Services1.Session.Session_Logoffforced($session.id)
}
else{
    write-host "Logging off $targetUser from $targetmachine"
    try{
        $Services1.Session.Session_Logoff($session.id)
    }
    catch{
        write-error "error logging the user off, maybe the sessions was locked. Try with -force"
    }
}

This session was locked

So let’s force that thing

Quickly grabbing all available REST api url’s for your Horizon version

One of the challenges with the Horizon REST API’s is that they are not feature complete yet and if you ain’t on the latest version you need to scroll trough the api explorer or Swagger UI to find if the URL you need is available. I have created a short script for both python and powershell that will show all the available urls.

If you’ve taken a good look at the Swagger page you’ll see there’s a link to the api docs almost at the top

If you open this you get something that looks like a json but it’s not readable (yet!)

Let’s grab the url’s with powershell first

$data = Invoke-WebRequest https://pod2cbr1.loft.lab/rest/v1/api-docs?group=Default
$json = $data |ConvertFrom-Json
$json.paths

this will give you all the available url’s from the docs and the methods they support

Now if you want to drill down deeper you can do a select -expandproperty on the url’s and with a get-member you get the available calls

$json.paths | select -expandproperty "/inventory/v1/rds-servers/{id}" | Get-Member

and with another select -expandproperty you see all the details

$json.paths | select -expandproperty "/inventory/v1/rds-servers/{id}" | select -ExpandProperty get

With Python you can start with something similar

import json,requests,urllib 
requests.packages.urllib3.disable_warnings() 
response = requests.get("https://pod2cbr1.loft.lab/rest/v1/api-docs?group=Default" , verify=False) 
data = response.json() 
for i in data["paths"]: 
    print(i)

but this will just give the url’s

To be able to drill down I decided to bring the url, method and the description into a list and print that if needed. This example is just with the method and url but you can add the description as well. The list is to make it easier to filter on.

import json,requests,urllib
requests.packages.urllib3.disable_warnings()
response = requests.get("https://pod2cbr1.loft.lab/rest/v1/api-docs?group=Default" , verify=False)

data = response.json()

list=[]
paths=data["paths"]

for i in paths:
    for method in paths[i]:
        obj = {}
        obj["method"] = method
        obj["url"] = i
        obj["description"] = paths[i][method]
        list.append(obj)

for i in list:
    print(i["method"], i["url"])

Community NVMe Driver for ESXi

This Fling is a collection of ESXi Native Drivers which enables ESXi to recognize and consume various NVMe-based storage devices. These devices are not officially on the VMware HCL and have been developed to enable and support the VMware Community.

Currently, this Fling provides an emulated NVMe driver for the Apple 2018 Intel Mac Mini 8,1 and the Apple 2019 Intel Mac Pro 7,1 allowing customers to use the local NVMe SSD with ESXi. This driver is packaged up as an Offline Bundle and is only activated when it detects ESXi has been installed on either an Apple Mac Mini or Apple Mac Pro.

VMware Cloud Foundation Powernova

VMware Cloud Foundation Powernova is a Fling built on top of VCF that provides the users the ability to perform Power Operations (Power ON, Power OFF) seamlessly across the entire inventory. It has a sleek UI to visualize the entire VCF inventory (which is the first of its kind for VCF) across the domains of VCF.

The UI is easy to use and elucidates the current Health and Power State of each node in the VCF inventory. Powernova lets the user work on the Power Operations on the components with domain specific inter dependencies automatically resolved.

Powernova also performs valid health checks on all nodes in the VCF inventory to ensure Power Operations are performed only on healthy nodes. Powernova takes minimal input (4 user defined inputs on their VCF system) and does all the magic for the users behind the scenes.

If any infrastructure maintenance activity, VCF migration activity, or power operations need to be performed only on specific domains in VCF, then Powernova is the one stop solution for all VCF users.

Workspace ONE Access Migration Tool

Workspace ONE Access Migration Tool helps ease migration of Apps from one WS1 Access tenant to another (on-premises to SaaS or SaaS to SaaS) and use cases that require mirroring one tenant to another (for setting up UAT from PROD or vice versa) by providing capabilities listed below

Features
  • Copying of App Categories
  • Migrating Weblinks (3rd party IDP), icons as is
  • Creating a link to federated apps and copying the icons (to maintain the same user experience)
  • Copying App Assignment to a Category mapping

Sample Data Platform Deployment on Virtualized Cloud Infrastructure

Data is king and your users need a sample data platform quickly.

With this Fling, you will leverage your VMware Cloud Foundation 4.0 with vRealize Automation deployment and stand a sample data platform based on vSphere Virtual Machines in less than 20-minutes comprising of Kafka, Spark, Solr, and ELK.

You can also choose whether to deploy a wavefront proxy and configure the components to send data to the wavefront proxy or use your own.

Community Networking Driver for ESXi

This Fling is a collection of ESXi Native Drivers which enables ESXi to recognize and consume various PCIe-based network adapters (See Requirements for details). These devices are not officially on the VMware HCL and have been developed to enable and support the VMware Community.

Code Stream Concourse Integrator

The Code Stream Concourse Integrator (CSCI) Fling provides integration between a vRealize Automation Code Stream and Concourse CI tools with which users can trigger Concourse CI pipelines from Code Stream pipelines without any additional tooling/scripting. This enables users to use the features from both the tools flexibly and seamlessly as per their needs. This solution is built using Code Stream’s extensibility feature named Custom Integration.

Managing application pools using the VMware Horizon Python Module

Earlier this week I added several methods to the VMware Horizon Python Module that are centered about application pools and I promised a blog post so here it is 🙂 In the module we have the following methods in the Inventory about Application Pools:

Preparation

In order to use the methods I am using this as standard configuration in my script

import requests, getpass, urllib, json, operator
import vmware_horizon
requests.packages.urllib3.disable_warnings()

url="https://loftcbr01.loft.lab"
username = "m_wouter"
domain = "loft.lab"
pw = getpass.getpass()


hvconnectionobj = vmware_horizon.Connection(username = username,domain = domain,password = pw,url = url)
hvconnectionobj.hv_connect()
print("connected")
monitor = obj=vmware_horizon.Monitor(url=hvconnectionobj.url, access_token=hvconnectionobj.access_token)
external=vmware_horizon.External(url=hvconnectionobj.url, access_token=hvconnectionobj.access_token)
inventory=vmware_horizon.Inventory(url=hvconnectionobj.url, access_token=hvconnectionobj.access_token)
entitlements=vmware_horizon.Entitlements(url=hvconnectionobj.url, access_token=hvconnectionobj.access_token)

All of the connects at the bottom is so I don’t need to think to do those if I need them when testing.

I end with

end=hvconnectionobj.hv_disconnect()
print(end)

Both the connected and end prints aren’t required at all but give me feedback about the status of the connection.

get_application_pools

This is the easiest method to use as it doesn’t require anything. It does allow for setting page sizes and filtering if needed. See this article if you want to know more about filtering: https://www.retouw.nl/2021/02/14/filtering-searching-and-pagination-with-the-python-module-for-vmware-horizon/ The method will return a list of dicts, for the first example I will show only the names of the items.

ap = inventory.get_application_pools(maxpagesize=100)
for i in ap:
    print(i["name"])

Or just with the entire list returned

ap = inventory.get_application_pools(maxpagesize=100)
print(ap)

get_application_pool

To get a single application pool you can use get_application_pool and it requires an application_pool_id, I will use the first one of the list of application to show it.

ap = inventory.get_application_pools(maxpagesize=100)
firstap=ap[0]
print(inventory.get_application_pool(application_pool_id=firstap["id"]))

delete_application_pool

To delete an application pool we again only need the application_pool_id I will combine both the get methods to show all application pools before and after the deletion. (with some prints not relevant for the code so I won’t show them below)

ap = inventory.get_application_pools(maxpagesize=100)
for i in ap:
    print(i["name"])
firstap=ap[0]

print(inventory.get_application_pool(application_pool_id=firstap["id"]))

inventory.delete_application_pool(application_pool_id=firstap["id"])

ap = inventory.get_application_pools(maxpagesize=100)
for i in ap:
    print(i["name"])

new_application_pool

Since I just deleted my firefox pool I will need to recreate it. The new_application_pool method requires a dict with quite a lof of values. This is the standard list that the swagger-ui gives you

{
  "anti_affinity_data": {
    "anti_affinity_count": 10,
    "anti_affinity_patterns": [
      "*pad.exe",
      "*notepad.???"
    ]
  },
  "category_folder_name": "dir1\\dir2\\dir3\\dir4",
  "cs_restriction_tags": [
    "Internal",
    "External"
  ],
  "description": "string",
  "desktop_pool_id": "0103796c-102b-4ed3-953f-3dfe3d23e0fe",
  "display_name": "Firefox",
  "enable_client_restrictions": false,
  "enable_pre_launch": false,
  "enabled": true,
  "executable_path": "C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\Firefox.lnk",
  "farm_id": "855ea6c5-720a-41e1-96f4-958c90e6e424",
  "max_multi_sessions": 5,
  "multi_session_mode": "DISABLED",
  "name": "Firefox",
  "parameters": "-p myprofile",
  "publisher": "Mozilla Corporation",
  "shortcut_locations": [
    "START_MENU"
  ],
  "start_folder": "string",
  "supported_file_types_data": {
    "enable_auto_update_file_types": true,
    "enable_auto_update_other_file_types": true,
    "file_types": [
      {
        "description": "Firefox Document",
        "type": ".html"
      }
    ],
    "other_file_types": [
      {
        "description": "Firefox URL",
        "name": "https",
        "type": "URL"
      }
    ]
  },
  "version": "72.0.2"
}

This does not say that all of these are required, what I have found to be an easy way to find what the minimums are is to  create an application pool with a single key value pair. display_name is always required so I will use that one. Experience has learned that this might require several tries so let’s go.

new_app_pool = {}
new_app_pool["display_name"] = "Firefox"

inventory.new_application_pool(application_pool_data=new_app_pool)

So the first hard requirements are display_name, executable_path and name, let’s add these and see what happens

new_app_pool = {}
new_app_pool["display_name"] = "Firefox"
new_app_pool["name"] = "Firefox"
new_app_pool["executable_path"] = "C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\Firefox.lnk"

inventory.new_application_pool(application_pool_data=new_app_pool)

It looks like we actually need some more: at least desktop_pool_id or farm_id since I am doing this against a connection server with no farms I’ll use a desktop pool.

desktop_pools = inventory.get_desktop_pools()
firstpool = desktop_pools[0]

new_app_pool = {}
new_app_pool["display_name"] = "Firefox"
new_app_pool["name"] = "Firefox"
new_app_pool["executable_path"] = "C:\\ProgramData\\Microsoft\\Windows\\Start Menu\\Programs\\Firefox.lnk"
new_app_pool["desktop_pool_id"] = firstpool["id"]

inventory.new_application_pool(application_pool_data=new_app_pool)

No errors and a peak in the admin console shows me that I again have a firefox application

update_application_pool

To update the pools we need the application_pool_id and again a dict, this time the dict needs things we want to update. Experience again learned me there are a few required key value pairs while the example in the swagger-ui shows lots, so let’s find those. I am going to use my new firefox app as the source for this. What I actually am going to try to change is the display_name so I will use that as the first key value pair.

filter = {}
filter["type"] = "And"
filter["filters"] = []
filter1={}

filter1["type"] = "Equals"
filter1["name"] = "name"
filter1["value"] = "Firefox"
filter["filters"].append(filter1)
ap = (inventory.get_application_pools(filter=filter))[0]
appid = ap["id"]
update_app = {}
update_app["display_name"] = "FF2"
inventory.update_application_pool(application_pool_id=appid, application_pool_data=update_app)

So here different key value pairs are required than when creating a new application pool, strange but there is nothing I can do about it! I will add these from the ap object I retrieve earlier in the script.

aps = inventory.get_application_pools(maxpagesize=100)
for i in aps:
    print(i["display_name"])
filter = {}
filter["type"] = "And"
filter["filters"] = []
filter1={}

filter1["type"] = "Equals"
filter1["name"] = "name"
filter1["value"] = "Firefox"
filter["filters"].append(filter1)
ap = (inventory.get_application_pools(filter=filter))[0]
appid = ap["id"]
update_app = {}
update_app["display_name"] = "FF2"
update_app["executable_path"] = ap["executable_path"]
update_app["multi_session_mode"] = ap["multi_session_mode"]
update_app["enable_pre_launch"] = ap["enable_pre_launch"]

inventory.update_application_pool(application_pool_id=appid, application_pool_data=update_app)

aps = inventory.get_application_pools(maxpagesize=100)
for i in aps:
    print(i["display_name"])

So with that you have the basics to retrieve, create, update and delete application pools using python

Filtering/Searching and pagination with the Python module for VMware Horizon

Yesterday I added the first method to the VMware Horizon Python module that makes use of filtering while the day before that I added pagination. VMware{Code} has a document describing available options for both but let me give some explanation.

Pagination

Pagination is where you perform a query but only get an x amount of objects returned by default. The rest of the objects are available on the next page or pages. This is exactly what I ran into with the vmware.hv.helper Powershell module a long time ago. With the REST api’s this is rather easy to add since if there are more pages/objects left the headers will contain a key named HAS_MORE_RECORDS. For all the methods that I add where pagination is supported you don’t need to handle this though as I have added it to the method itself. What I did add was the option the change the maximum page size. I default to 100 and the maximum is 1000, if you supply an interrupt higher than 1000 this will be corrected to 1000.

Filtering

Filtering needs some more work from the user of the module to be able to use it.

What options are there for filtering?

For the type we have: And, Or and Not

For the filters themselves there are: Equals, NotEquals, Contains, StartsWith and Between.

The formula is you pick one from the first row and combine that with one or more from the second row.

To apply these the document describes the base schema like this:

{
    “type”: ”And”,
    “filter”: <filter object>
}

and a filter object looks like this:

{
    "type":"Equals",
    "name":"domain",
    "value":"ad-example0"
}

or this for a range:

{
    "type":"Between",
    "name":"assignedUsers",
    "fromValue":"10",
    "toValue":"20"
}

Combining both into a single object looks like this:

{
    "type":"Not",
    "filter": {
        "type":"Equals",
        "name":"domain",
        "value":"ad-example0"
    }
}

This all looks like a dictionary with a nested dictionary when translating it to Python but when you have multiple filters it suddenly looks like this:

{
    "type":"And",
  "filters": [
        {
            "type":"Equals", 
            "name":"domain",
            "value":"ad-example0"
        },
        {
            "type":"StartsWith", 
            "name":"name",
            "value":"test"
        }
    ]
}

otherwise know as a dictionary with a list of dictionaries in it and since the latter also works with a single dict inside the list I have taken that route. The document also describes encoding and minifying the code to it works for a REST api call but I have done all of that for you so no need to worry about it, just build the dictionary and you are good!

Now let’s actually perform a search

First I create my base object with the type AND and a list for the filters key

filter_dict = {}
filter_dict["type"] = "And"
filter_dict["filters"] = []

Next I create the filters object where the type is contains and I filter on the field name with the value LP-00

filter1={}
filter1["type"] = "Contains"
filter1["name"] = "name"
filter1["value"] = "LP-00"

And now I add the filters1 object to the filter_dict filters list

filter["filters"].append(filter1)

and I get the machines with a pagesize of 1 to show the pagination (the pool with these machines only has 2 😉 )

machines = obj.get_machines(maxpagesize=1, filter = filter_dict)

And this would be the entire python script

import requests, getpass, urllib, json
import vmware_horizon

requests.packages.urllib3.disable_warnings()

url="https://loftcbr01.loft.lab"
username = "m_wouter"
domain = "loft.lab"
pw = getpass.getpass()

hvconnectionobj = vmware_horizon.Connection(username = username,domain = domain,password = pw,url = url)
hvconnectionobj.hv_connect()

obj = vmware_horizon.Inventory(url=hvconnectionobj.url, access_token=hvconnectionobj.access_token)

filter_dict = {}
filter_dict["type"] = "And"
filter_dict["filters"] = []
filter1={}
filter1["type"] = "Contains"
filter1["name"] = "name"
filter1["value"] = "LP-00"

filter["filters"].append(filter1)

machines = obj.get_machines(maxpagesize=1, filter = filter_dict)

for i in machines:
    print(i["name"])

hvconnectionobj.hv_disconnect()

And it shows this in python:
