I have just added a page that lists the Horizon 8 2209 changes in the API’s. If you’re interested in the overall release notes, please see this link.
Some of the changes that stand out are brand new calls related to Radius & SAML settings but also options to bind to a domain, setting up unauthenticated users. licenses and pre-logon settings.
As always, a complete overview of all calls can be found in the API Explorer. But this is a list of the changes.
So besides the cpu/memory changes we obviously also have something called selective_push_image. This has to do with the added functionality of pushing a secondary image from Horizon 2111. While the example shows it as true the data model makes clear that it is not required and defaults to false. The array of machine_ids reflects the list of machines where the secondary image has to be applied.
compute_profile_num_cores_per_socket integer($int32)
example: 1
minimum: 1
exclusiveMinimum: false
exclusiveMaximum: false
Indicates the number of cores per socket for the CPU in the compute profile to be configured on clones.
If set, both compute_profile_num_cpus and compute_profile_ram_mb need to be set.
compute_profile_num_cpus integer($int32)
example: 4
minimum: 1
exclusiveMinimum: false
exclusiveMaximum: false
Indicates the number of CPUs in the compute profile to be configured on clones.
If set, this must be a multiple of compute_profile_num_cores_per_socket.
compute_profile_ram_mb integer($int32)
example: 4096
minimum: 1024
exclusiveMinimum: false
exclusiveMaximum: false
Indicates the RAM in MB in the compute profile to be configured on clones.
machine_ids [
example: List [ "816d44cb-b486-3c97-adcb-cf3806d53657", "414927f3-1a3b-3e4c-81b3-d39602f634dc" ]
Set of machines from the desktop pool on which the new image is to be applied. This can be set when selective_push_image is set to true.
selective_push_image boolean
example: true
Indicates whether selective push image is to be applied. If set to true, the new image will be applied to specified machine_ids in the desktop pool. The image published with this option will be held as a pending image, unless it is promoted or cancelled. The default value is false.
To be able to use this I have updated my previous image deployment script for Horizon 2206.
New arguments are:
AddVirtualTPM
Boolean to add a virtual TPM or not
SecondaryImage
Boolean to define the image as secondary (required if you also supply machine_ids)
Machine_Ids
Array with machine_ids to supply the secondary image to
CoresPerSocket
Int with # of Cores per Socket
CPUs
Int for total number of cpus
MemoryinMB
Memory in mb so 4096 or 6192 for example

Since several version in each VMware Horizon release notes pages there has been this mention:
This links to this page: VMware Horizon REST APIs (84155) for a while this page was updated with the latest additions to the REST api’s but I guess people didn’t want to do that anymore so that page now simply links to the API Explorer:
Since I used this changelog to decide on what I wanted to blog about I thought it was time to create a changelog myself. What I did was download all the swagger specifications and compare them. For reasons I had to do this in excel but at least I now have a nice source for this. (ping me if you would like to have the excel file). This result in a new menu item at the top of my blog with the changelog for every Horizon 8 version. Yes I know the rest api’s have been available since 7.10 but I decided to start with 8.0. Please use the menu on top of the links below to go to the changelog for the version that you would like to see.
For those of you who haven’t seen my demo last week at the VMUG EUC day I have created a new script that will push a new Golden Image to a RDS farm. The same API call can also be used to schedule a recurring maintenance but that will have to wait for a future post.
What you need to run it are the following parameters:
-Credentials: credentials object from get-credential
-ConnectionServerURL: Full url to the connection server https://pod1cbr01.loft.lab for example
-vCenterURL : Full url to the vCenter Server: https://pod1vcr1.loft.lab
-DataCenterName : name of the Datacenter in vCenter
-BaseVMName : VM name of the new golden image
-BaseSnapShotName : name of the snapshot to be used
-FarmName : name of the RDS farm to push the image to
-StoponError : Boolean $True or $False to stop on error or not. Defaults to $true
-logoff_policy : String in capitals to wait for the users to logoff (WAIT_FOR_LOGOFF) or to forcefully log them off (FORCE_LOGOFF). Defaults to WAIT_FOR_LOGOFF
-Scheduledtime : datetime object for the time to schedule the image push. If not provided it will push the image immediately.
In my Lab I have this RDS Farm:
The last Image push actually failed
And It’s using this Golden Image with the Created by Packer Snapshot
With the following command I will push the new image:
Today I got the question from someone that they where trying to send messages to users but had issues with adding the session id’s to the json. I decided to make a quick and nice script that’s able to send a message to all sessions. This uses the standard functions that I always use, the standard Get-HorizonRestData function that I created in this blog post and two custom functions that I created for this script.
The first new function is get-horizonsessions this function gets all local sessions utilizing the get-horizonrestdata function. As you can see pretty basic nothing fancy about it.
function get-horizonsessions(){
[CmdletBinding(DefaultParametersetName='None')]
param(
[Parameter(Mandatory=$true,
HelpMessage='url to the server i.e. https://pod1cbr1.loft.lab' )]
[string] $ServerURL,
[Parameter(Mandatory=$true,
HelpMessage='Part after the url in the swagger UI i.e. /external/v1/ad-users-or-groups' )]
[PSCustomObject] $accessToken
)
try{
Get-HorizonRestData -ServerURL $url -RestMethod "/inventory/v1/sessions/" -accessToken $accessToken
}
catch{
throw $_
}
return $results
}
The second one isn’t that more advanced besides that it has a few more parameters including one called $session_ids that requires an array of the session id’s to where you want to send a message. It creates an ordered hashtable that stores the message, message_type and the array of id’s. This hashtable is than converted to a json file and used as the body for the rest call.
function send-horizonmessage(){
[CmdletBinding(DefaultParametersetName='None')]
param(
[Parameter(Mandatory=$true,
HelpMessage='url to the server i.e. https://pod1cbr1.loft.lab' )]
[string] $ServerURL,
[Parameter(Mandatory=$true,
HelpMessage='Part after the url in the swagger UI i.e. /external/v1/ad-users-or-groups' )]
[PSCustomObject] $accessToken,
[Parameter(Mandatory=$true,
HelpMessage='url to the server i.e. https://pod1cbr1.loft.lab' )]
[array] $Session_Ids,
[Parameter(Mandatory=$true,
HelpMessage='url to the server i.e. https://pod1cbr1.loft.lab' )]
[string] $Message,
[Parameter(Mandatory=$true,
HelpMessage='url to the server i.e. https://pod1cbr1.loft.lab' )]
[validateset("ERROR","WARNING","INFO", IgnoreCase = $false)]
[string] $Message_Type
)
$jsonhashtable = [ordered]@{}
$jsonhashtable.add('message',$message)
$jsonhashtable.add('message_type',$Message_Type)
$jsonhashtable.add('session_ids',$Session_Ids)
$json = $jsonhashtable | convertto-json
try{
$results = Invoke-RestMethod -Method Post -uri "$ServerURL/rest/inventory/v1/sessions/action/send-message" -ContentType "application/json" -Headers (Get-HRHeader -accessToken $accessToken) -body $json
}
catch{
throw $_
}
return $results
}
Than I use these 2 lines to actually send the message (after authenticating first, duh). If you want to filter the sessions that can be added to the get-horizonsessions or manually do it on the $sessions array. Be aware that there are no names in this array so you need to gather any of the optional id’s first.
For years people have been asking, when can we start creating Horizon Desktop Pools using REST? The first years the answers was that there was no REST Api at all but since they added REST in 7.10 Horizon the answer was whenever VMware feels like adding this option. With the recent release of Horizon 8 2111 they have finally added the option to do this. I have created a script that uses a json file as base I grabbed this from the api explorer. But the sample below is already edited down so I can create a simple desktop pool. You can grab my version below or here on Github.
Essentially using only the json file could be enough to create a pool but I decided to create a powershell script that uses the json as a base and where I add functionality to make it more flexible. You cna supply names for things like datacenter, desktop pool name, display name and description & many others. If you want you can hardcode these names or even the id’s if you like but I have only done that in the json for the, access_group_id and the instant_clone_domain_account_id. You can go as crazy as you like and define each and every option as a parameter but I prefer a good base with the things that are changed the most often as parameters.
This is a sample of how I start the script, there is no feedback as the POST command doesn’t give any proper feedback if it ran well. I think the params are clear but you need to be careful to use a Relative Distinguished Name and not a normal Distinguished Name (the DC = parts are missing as you can see). For datastores you need to always need to use an array.
Now the script itself, I am still using the default rest functions and only a slight bit of error handling for checking if the json exists and importing it. For the rest it’s a list of api calls that you (partially) have seen before in other scripts. The datastoressobjects array is filled with separate objects per datastore. The json is converted to a regular array at the beginning so it’s very easy to replace all variables that need replacing. To convert the object to a usable json file you need to change the max depth as this is default only 2 an that’s not enough for this json file. I set it to 100 just to keep things easy. If you want to download the script I would recommend grabbing it from Github.
In a future blog post I will cover adding different VM Networks to the desktop pool. With this json file the default nic of the Golden Image is used.
So just found out that Horizon 8 2111 dropped today and there have been some welcome changes to the rest api’s. Luckily VMware does have these covered by now in THIS kb article.
In short these are the changes:
Inventory : Desktop Pools
Create desktop pool
Update desktop pool
Delete desktop pool
v5 version of List
v5 version of Get
Inventory : Desktop Actions
Validate Installed Applications
Validate VM Names Info
Resume Task on Desktop pool
Pause task on Desktop pool
Inventory : Farms
v3 version of List
v3 version of Get
v2 version of Create
v2 version of Update
Inventory : Farm Actions

Remove RDS servers from farm
Schedule Maintenance (and image management schedule maintenance)
Cancel Schedule Maintenance
Validate Installed Applications
Inventory : Global Application Entitlements
v2 version of List
v2 version of Get
Create Global Application Entitlements
Update Global Application Entitlements
Delete Global Application Entitlements
List Compatible Backup Global Application Entitlements
Inventory : Global Desktop Entitlements

Create Global Desktop Entitlements
Update Global Desktop Entitlements

so finally we’re able to create desktop pools using REST and to push a new image to rds farms. I will make sure to update the Python module ®Soon and create some blog posts on the new options.
A while ago Robin Stolpe (Twitter) asked me if it was possible to find what machines a user is assigned to in a Horizon environment. To answer this I first started messing with the soap api’s and had a really hard time to filter for the user id with the various machine related queries. When looking for the assignedUser property this was no problem but this has been deprecated and replaced by assignedUsers because of the added functionality for assigning multiple users to a machine. Instead of becoming too frustrated I decided to switch paths and user Powershell with the rest api’s.
TLDR: I have defined a broadly usable function for just about all Horizon REST GET api calls with or without filtering that also works for GET calls without any additions and for GET calls that require an Id for example. You can scroll down to the bottom to get that function and a script that uses it.
Warning: the sample code in the script & example function require PowerShell 7!
Filtering
One of the things I hadn’t done before with these was filtering and pagination in a more useful way than just writing the entire url out. VMware has a guide available for filtering that can be found here. This was a good way to get started but I found it easiest to skip the single searches entirely and always use the And or Or filtering types for chained filtering.
The method I am using to create the filter is to first define an ordered hashtable. Why ordered? The api calls require the Name/value pairs in a certain order and if you just add them to a regular hashtable this order will change.
$filterhashtable = [ordered]@{}
Next I add the first Name/value pair for the filtertype, this is either And or Or
$filterhashtable.add('type', 'And')
Next I add another pair with name filters and value an array. I could use .add again or just set the name like I do here:
$filterhashtable.filters = @()
The filters name array members again need to be ordered hashtable’s (as you can see I search for a user here)
For the pagination I needed the HAS_MORE_RECORDS property of the returned headers. If this is TRUE there are more records to be found, sadly this is not available in the classic invoke-restmethod from Powershell v5. With Powershell 7 you can add -ResponseHeadersVariable responseheader to store the headers in a variable called $responseheader. With this variable you can easily create a do while loop.
Please be advised that without some additional parameters this code isn’t usable yet, scroll down for something you can really use.
[sta_anchor id=”function” /]
The function
To combine the above 2 items I have created a function that can use all of the above but is also able to do regular get calls and get calls that require an id in the url.
function Get-HorizonRestData(){
[CmdletBinding(DefaultParametersetName='None')]
param(

if($filteringandpagination){
if ($filters){
$filterhashtable = [ordered]@{}
$filterhashtable.add('type',$filtertype)
$filterhashtable.filters = @()
foreach($filter in $filters){
$filterhashtable.filters+=$filter
}
$filterflat=$filterhashtable | convertto-json -Compress
$urlstart= $ServerURL+"/rest/"+$RestMethod+"?filter="+$filterflat+"&page="
}
else{
$urlstart= $ServerURL+"/rest/"+$RestMethod+"?page="
}
$results = [System.Collections.ArrayList]@()
$page = 1
$uri = $urlstart+$page+"&size=$pagesize"
$response = Invoke-RestMethod $uri -Method 'GET' -Headers (Get-HRHeader -accessToken $accessToken) -ResponseHeadersVariable responseheader
$response.foreach({$results.add($_)}) | out-null
if ($responseheader.HAS_MORE_RECORDS -contains "TRUE") {
do {
$page++
$uri = $urlstart+$page+"&size=$pagesize"
$response = Invoke-RestMethod $uri -Method 'GET' -Headers (Get-HRHeader -accessToken $accessToken) -ResponseHeadersVariable responseheader

}

$results = Invoke-RestMethod $uri -Method 'GET' -Headers (Get-HRHeader -accessToken $accessToken) -ResponseHeadersVariable responseheader
}
else{
$uri= $ServerURL+"/rest/"+$RestMethod
$results = Invoke-RestMethod $uri -Method 'GET' -Headers (Get-HRHeader -accessToken $accessToken) -ResponseHeadersVariable responseheader
}
return $results
}
As you can see there are several arguments:
ServerURL
This is the url to the connection server i.e. https://server.domain
Filters
An Array of ordered hashtables as you can find in the filtering paragraph
filtertype
Sets the filter type, this needs to be And or Or
PageSize
This is optional if you want to change from the default 500 results that I have set
RestMethod
This is the RestMethod that you can copy from the Swagger URL or API Explorer.
AccessToken
This is the accesstoken you get as a result when using open-hrconnection from previous samples to authenticate (see the sample script below)
Filteringandpagination
Add this argument to use the filtering and/or pagination options
Id
Use this for REST API Get calls where an Id is required in the URI
The script below (and available on Github here) aks for credentials if you don’t supply the object, connectionserver FQDN (no url needed), user and domain to search for and returns an array of machines the user is assigned to. It uses the default functions Andrew Morgan created a long time ago and my function to use the get methods.
<#
.SYNOPSIS

I use it like this to only display the machine names
So last year Guy Leech asked if if I had a script to identify machines running on an old snapshot. I Created a script for that here. This week Madan Kumar asked for a script that finds these same VDI desktops but that also cleans them out if needed. For this I have created the Horizon_cleanup_old_images.ps1 script (yes I suck at making up names).
If you run a get-help for the script you’ll see this:
By default the script only requires a Connectionserverfqdn and poolname as it works on a per pool level. It will try to give the users a gracefully logoff and has options to force the logoff ( in case their sessions is locked) or to delete the machine. And if you just want to have a preview there’s an option for that as well.
Optional arguments are:
-credential: this can be created with get-credential or can be retrieved from a stored credentials xml file, just make sure that it looks like domain\username and password
-deletedesktops: if used it will forcefully try to logoff the users but always deletes the desktop
-forcedlogoff: A normal logoff doesn’t work when the sessions is locked so you might need to force it
-preview: no actions are taken, just the information will be displayed to screen.
Yes I use write-host but it’s all 1 liners so shouldn’t be too slow and I like colors but as you see with the preview mode it shows what would happen. One of these sessions is locked so let’s see what happens when I log them off.
yes an error but I think it’s clear why, the graceful logoff worked for 2 users but not the third one, I will add the forced option now.
That looks good and when I look at the desktop pool everything is fine there as well.
And that’s being confirmed by the script
Now I will use the delete option for my other desktop pool.
First again with the preview option
and without
and seen from the Horizon Admin
As linked above the script can be found on github but also below this line.
<#
.SYNOPSIS
Cleans up desktops running on an image that's not the default for a desktop pool
.DESCRIPTION
This script uses the Horizon soap api's to pull data about machines inside a desktop pool that are running on a snapshot or base vm that's not currently configiured on the desktop pool. By default it logs off the users but there are options to forcefully logoff the user or delete the machines.
.EXAMPLE
.\Horizon_cleanup_old_image.ps1 -Credential $creds -ConnectionServerFQDN pod2cbr1.loft.lab -poolname "Pod02 Pool02" -delete -preview
.PARAMETER Credential
Mandatory: Yes
Type: PSCredential
Object with credentials for the connection server with domain\username and password
.PARAMETER ConnectionServerFQDN
Mandatory: No
Default: String
FQDN of the connection server to connect to
.PARAMETER Poolname
Mandatory: Yes
Type: string
Display name of the Desktop Pool to check
.PARAMETER Deletedesktops
Mandatory: No
Enables the deleteion of the desktops, this includes an attempt to forcefully logoff the users.
.PARAMETER Forcedlogoff
Mandatory: No
Enables the forcefully logging off of the users.
.PARAMETER Preview
Mandatory: No
Makes the script run in preview mode and not undertake any actions.

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.
