Nutanix .Next 2019 Copenhagen Day 1

Having arrived in Copenhagen on Sunday I have had plenty of time to go for some sightseeing but yesterday things really started for me at the Nutanix .Next event in Copenhagen. I haven’t done any sessions to be honest but had a full schedule anyway. First we started of at the keynote with the NTC’s getting a shoutout from marketing Chief Ben Gibson and one of us on just before at the celebration of 10 years of Nutanix: Andrea Mauro. Several announcements where made during the keynote like Metro availability for AHV, one minute RPO for Xi Leap and ESXi availability for Xi Leap as well. For me the highlight was Julie O’Brien (VP of marketing ) doing a tech demo on stage.

What followed after the keynote was a lot of networking and offcourse the yearly NTC lunch. While it was only a small group it actually was great to catch up with everyone. Too bad Angelo didn’t have a microphone because he was singing with the music as usual.

In the afternoon I did a roundtable session about a new type of certification that Nutanix is exploring. This was with a small group of ntc’s and I have to say the discussions where great and what is actually the future of us engineers and what does an engineer actually do?

For the evening keynote Angelo got us in the executive lounge (that hadn’t been used a lot during the day according to some of the staff). Too bad the part with Dimitri Vegas and Like Mike wasn’t broadcasted but they made up for that at the awesome party in the evening. They did a great set with lots of oldskool music that got the croud really going.

(yes my smartphone can’t handle 120+db’s of music)

 

The VMware Labs flings monthly for September 2019

And yet another month gone, next week I will be in Kopenhagen for Nutanix .Next and the month after that I will be speaking at VMworld Barcelona. Will I see you at either of these two events? Last month one new fling was released:  Kubernetes eXtensible Desktop Client (KXDC) , seven received updates: App Volumes Entitlement Sync, vSphere HTML5 Web Client, DoD Security Technical Implementation Guide(STIG) ESXi VIB, VMware OS Optimization Tool, vSphere Mobile Client, Workspace One UEM Workload Migration Tool, USB Network Native Driver for ESXi and one was marked deprecated: VIB Author.

New releases

Kubernetes eXtensible Desktop Client (KXDC)

The Kubernetes eXtensible Desktop Client (KXDC) is a simple and multi-platform desktop client for Kubernetes (K8S). In the same way the kubectl command requires only a valid kubeconfig file to run commands against a K8S cluster, KXDC requires you just to configure one or more valid kubeconfig files to interact with one or more K8S clusters.

Main features:

  • Support for multiple kubeconfig files.
  • UI-driven interaction with the most frequently used K8S entities.
  • One-click terminal with the proper KUBECONFIG env variable set.
  • Generation of custom kubeconfig files for a given namespace.
  • Highlight sustainability and security-related data.

Updated flings

App Volumes Entitlement Sync

The App Volumes Entitlement Sync fling will read, sync and compare entitlements between various App Volumes instances.

Changelog

Version 2.2

  • Ignore Extra AppStacks on Primary or Secondary Server – these would cause compare to crash
  • Export Primary or Secondary Server Entitlements to XML

vSphere HTML5 Web Client

Do you want to have the latest version of the html5 client? Than you need the vSphere HTML5 Web Client fling!

Changelog

Fling 4.3.0 – Build 14483008
New Features

  • Ability to customize the header color per vCenter to differentiate vCenter servers. Go to Administration -> System Configuration and select the vCenter for which you want to change the header color.

The VMware OS Optimization Tool or OSOT in short is one of the best tools around to optimize your VDI image before publishing a desktop or rds host.

Changelog

September, 2019, b1110

  • New Common Options button – Allows you to quickly choose and set preferences to control common functionality. These would normally involve configuring multiple individual settings but can now be done with a single selection through this new interface
  • Split Windows 10 into two templates to better handle the differences between the versions; one for 1507-1803 and one for 1809-1909
  • Improved and new optimizations for Windows 10, especially for 1809 to 1909.

Updated and changed template settings for newer Windows 10 versions to cope with changes in the OS, registry keys and functionality:

  • Unavailable links in reference tab
  • Windows Store is unavailable after optimizing
  • Start menu may delay after optimizing
  • VMware Tools stops running after optimizing
  • Analysis Summary Graph is cropped

vSphere Mobile Client

Personally I think a phone screen is too small but this was one of the most asked questions the last few years: when can we manage vSphere from our phones? Well now you can with the vSphere Mobile Client fling.

Changelog

Looking forward to Nutanix .Next in Copenhagen

This year will mark my third visit to the European Nutanix .Next conf, this time in lovely Copenhagen. This year though will be my first time as the Nutanix User Group Champion for The Netherlands. While the sessions will be awesome I am mostly looking forward to meeting the international #vCommunity once again.

My trip will start Sunday evening since the airfield closes to home only flies to Copenhagen on Sunday evening or Monday morning at cr*p o clock. This means I have spare time on onday and Tuesday that I will spend sightseeing if the weather permits. Hopefully I can get some people together to do a guided bicycle ride through town.

If you want to meet up during the event than hit me p on Twitter or look at the community area, there’s a good chance of seeing me there. I will be trying to visit a variety of sessions from architectural deep dives to new technology like Nutanix Mine with a side meal of IoT and the Edge. And I am certainly looking forward to the closing keynote because it sounds like it will be awesome. Maybe not as awesome as the keynote with Dr. Jane Goodall but that one is hard to top anyway.

So will I see you at .Next for some coffee and stroopwafels?

 

 

The VMware Labs flings monthly for August 2019

It’s been a bit quiet on the fling front with VMworld US happening. None the less there have been two new releases and three updates. New releases are the vSAN Performance monitor and Enterprise OpenShift as a Service on Cloud Automation Services flings. Updated where the vSphere Mobile Client, vRealize Operations REST Notifications Helper and Virtual Machine Compute Optimizer.

New Releases

vSAN Performance Monitor

The vSAN performance monitor is a monitoring and visualization tool based on vSAN Performance metrics. It will collect vSAN Performance and other metrics periodically from the clusters configured. The data collected is visualized in a more efficient and user-friendly way. The vSAN performance monitor comes with preconfigured dashboards which will help customers evaluate the performance of vSAN clusters, identify and diagnose problems, and understand current and future bottlenecks. The dashboards are heavily inspired by vSAN Observer.

The vSAN performance monitor is delivered in a virtual appliance with three major components, i.e., a Telegraf collector, InfluxDB, and a Grafana frontend.

  • Telegraf: Telegraf is the agent that collects metrics from vSAN cluster and stores them in InfluxDB.
  • InfluxDB: InfluxDB is the database to store the metrics
  • Grafana: We use Grafana as the frontend to virtualize the metrics stored in the InfluxDB

Once deployed, users will need to do some simple configuration changes to point the collector to target vSAN cluster(s) and start the service. After that, the data will be collected periodically and can be visualized for meaningful insights.

Enterprise OpenShift as a Service on Cloud Automation Services

This Fling enables a cloud admin to download the package, integrate with Cloud Assembly and other Infrastructure services and be able to provide an “OpenShift Cluster as a Service” offering. This Fling automates the end to end deployment process. End users can simply request for and get an enterprise grade distributed instance of OpenShift Cluster. This Fling provides all the required packages to configure and deploy an enterprise production grade OpenShift cluster using VMware Cloud Assembly Services with minimal effort and in a repeatable, fully automated fashion.

Updated Flings

vSphere Mobile Client

The vSphere Mobile Client is under heavy development to make sure we have the best experience in managing our vSphere environments using our mobile phones.

Changelog

Version 1.4.0

New features

  • Cluster view

vRealize Operations REST Notifications Helper

The vRealize Operations REST Notifications Helper helps in creating better REST notifications of alerts.

Changelog

Version 1.2.1

  • Updated instructions for v1.2
  • Minor fixes and improvements

Version 1.2.0

  • Multiple endpoint configurations
  • Blacklist
  • Windows support
  • Minor new features, improvements and fixes

Virtual Machine Compute Optimizer

The Virtual Machine Compute Optimizer (VMCO) is a Powershell script that uses the PowerCLI module to capture information about the hosts and VMS running in your vSphere environment, and reports back on whether the VMs are configured optimally based on the Host CPU and memory.

Changelog

Version 1.0.4

  • Added a -Property filter to the Get-View commands for hosts and VMs to reduce time and amount of returned data
  • Removed if statement in Get_Optimal_CPU function that included $hostCPUs as it was not yet being used

 

Updates to the Horizon API’s in PowerCLI 11.4

So today PowerCLI 11.4 was released with the following updates:

  • Add support for Horizon View 7.9
  • Added new cmdlets to the Storage module
  • Updated Storage module cmdlets
  • Updated HCX module cmdlets

As usual we need to wait for API explorer to be updated before we get the exact changes to the api’s but I already grabbed s short list by comparing the methods. Later I will create a more elaborate blog post about the changes if I have an overview. What I do see are some new additions that might be added to the vCheck for Horizon.

Also: even though the updates are for Horizon 7.9 there’s a good chance that a lot of this also works for previous versions, the examples below where done with 7.8.

  • Datacenter
  • DesktopHealth
  • Gateway
  • GatewayHealth
  • MessageClient
  • Monitoring
  • PersistentDiskQueryService
  • Privilege
  • SecondaryCredentials
  • SessionStatistics
  • StorageAccelerator
  • UsageStatistics
  • Validator
  • VirtualCenterStatistics

Sadly it’s late so I can only show a couple of examples:

$services.Privilege.Privilege_ListSelectablePrivileges()

 

$services.SessionStatistics.SessionStatistics_GetLocalSessionStatistics()

Finally we can reset the usage counters as well now

And some statistics from vCenter

($services.VirtualCenterStatistics.VirtualCenterStatistics_listSummaryStatistics())
($services.VirtualCenterStatistics.VirtualCenterStatistics_listSummaryStatistics()).DataStoreSummaryStatistics

Generating a clean Host Profile using PowerCLI

First of all: I love Host Profiles! But they’re easy to mess up as well, leave something selected related to hardware and an update in ESXi, vib’s or even a firmware update might break it. For a customer where we are going to do the entire vSphere build from scratch I got the idea to generate an empty Host Profile and extend that one using scripting. At first I though this would be an easy thing but it definitely isn’t, a reply from PowerCLI guru Luc Dekens at the VMware{Code} forums set me on the right path to do so. Luc’s remark that editing Host Profiles might take some reverse engineering for the lack of documentation is a huge understatement. It has cost me many many hours to build the script below.

I strongly recommend having the reference host as clean as possible.

These are the steps the script takes

  1. connect to vCenter
  2. extract a new Host Profile
  3. Gets the new Host Profile
  4. Copies all members of the new Host Profile to an object that can be edited
  5. Sets everything that I could find in my environment to false
  6. Updates the Host Profile with the edited object

Required parameters

  • vCenter
    • Your vCenter host
  • Referencehost
    • the name of the host in vCenter
  • Hostprofilename
    • Name for the Host Profile

There are also a couple of optional parameters:

  • dnshost
    • It’s mandatory to have a DNS set in the defaulttcpipstack. With this parameter you can change this.
  • domainname
    • Like DNS it’s mandatory to have a domainname set in the defaulttcpipstack. With this parameter you can change this
  • Cleanup
    • This one defaults to false but can be set to true. It will remove all NFS Datastores, vmkernel ports, portgroups, device aliases and direct i/o profiles.
    • Use this one with care, if you apply it to a host it will most probably remove all networking details for that host making it unusable.

This is how a manual extracted Host Profile looks

This is how a Host Profile looks after using my script without the cleanup option, everything is deselected but the device aliases for example are kept.

.\create_clean_hostprofile.ps1 -vcenter vCenter -Hostprofilename demo_no_cleanup -referencehost hostname

And this is how it looks with the cleanup used.

.\create_clean_hostprofile.ps1 -vcenter vCenter -Hostprofilename demo_no_cleanup -referencehost hostname -cleanup $true

The script itself can be found on Github as well:

I have been named EUC Champion for 2019!

A couple of weeks ago I was informed that I would be awarded the EUC Champion for the second time.  The EUC Champions program grew from 35 to 42 and you can find all of us over here: https://www.vmware.com/euc-champions/current-champions.html As you can see in that list my very good friend and vmug stage buddy Hans Kraaijeveld was also awarded the EUC Champion title as well into this EUC elite group of people.

So what are the EUC Champions?

What is the EUC Champions program?
EUC Champions is an experts-only program that provides a forum for the EUC community and VMware EUC product teams to share industry trends, new product information and ideas through in-person meetings, networking events, industry conferences and webinars.

This is the official statement but there is more. We also have access to dedicated EUC Champions Slack channels at the VMware slack with direct contact to some of the EUC product teams. Also the knowledge sharing between each other has been awesome in my opinion. Plus we get to test some flings that Andrew Morgan created that might or might not be released at https://labs.vmware.com/flings

Do you also think you have it to become an EUC Champion? You can find more info at https://www.vmware.com/euc-champions.html

What did I do to become an EUC Champion? Well it’s my blogging over here but certainly also presenting at vmug’s about EUC related things.

 

The VMware Labs flings monthly for July 2019

So I am in the middle of my summer holiday but stil it’s time for this monthly overview. I see two new flings with the Virtual Machine Compute Optimizer and Machine Learning on VMware Cloud Foundation tools. No less than six have received updates: vSphere Mobile Client, Desktop Watermark, HCIBench, Horizon Toolbox, Horizon Helpdesk Utility and Horizon Session recording. I already blogged about the updates to the Horizon Helpdesk Utility over here.

New Releases

Machine Learning on VMware Cloud Foundation

Want to do things with big data? This Fling might be able to help you with that on VCF, It could do with a proper logo though.

This Fling provides a platform for Data Scientists to quickly setup a virtualized cloud infrastructure to conduct data science experiments:

  • Virtualized environment based on VMware cloud and Kubernetes
  • Currently support CPU only (but will support GPU in future)
  • Based on Open Source Kubeflow, Horovod

Provides a set of example Notebooks and libraries for common data science tasks, including:

  • Data collection and cleaning (extract data from various sources, and describe the data semantics using metadata)
  • Data cleansing and transformation (clean up collected data and transform them from its raw form to a structured form more suitable for analytic processing)
  • Model training (develop predictive and optimization machine learning models)
  • Model serving (deploy model into a run time environment where online request will be served)

Virtual Machine Compute Optimizer

I personally wouldn’t call the Virtual Machine Computer Optimizer a fling since it’s a script but it’s here.

The Virtual Machine Computer Optimizer (VMCO) is a Powershell script that uses the PowerCLI module to capture information about the hosts and VMS running in your vSphere environment, and reports back on whether the VMs are configured optimally based on the Host CPU and memory. It will flag a VM as “YES” if it is optimized and “NO” if it is not. For non-optimized VMs, a recommendation is made that will keep the same number of vCPUs currently configured, with the optimal number of virtual cores and sockets.

Note that the VMCO will not analyze whether your VMs are configured with the correct number of vCPUs based on the VM’s workload. A more in-depth analysis tool such as VMware vRealize Operations Manager can make right-sizing determinations based on workload and actual performance.

Update flings

Horizon Session Recording

The Horizon Session Recording fling gives the Horizon admin a tool to record sessions for troubleshooting reasons for example.

Changelog

Version 1.2.2

  • Added support for horizon 7.8 and above
  • Added support for recording based on group memberships
  • Many bug fixes in agent
  • Bug fixes in server

Horizon Helpdesk Utility

Like I said I already blogged about the changes in the Horizon Helpdesk Utility but here’s the changelog, just to be complete.

Changelog

Version 1.4.0.1

  • No longer requires a helpdesk license! Yay!
  • Added the ability to interact with vCenter machines
  • Added the ability to open vCenter VM consoles
  • Added the ability to perform bulk machine actions
  • Added the ability to perform refresh / recompose tasks directly from helpdesk.
  • Fixed performance issues with multiple windows open (see single instance).
  • Fixed a crash when logon durations could not be accessed.
  • Added polling to allow logon durations to be received if notavailable when the session page is requested.
  • Fixed a crash in the ending of processes.
  • Fixed a metric ton of bugs with delegated administration.
  • Fixed a memory leak in the tray icon menu, of all places.
  • Removed the logon page graphic as it was to much of a pain to change it’s colour when changing themes

Changelog

v1.0 – Build 20190724-signed

  • Added a new attribute %DATETIME% to show hour and minute info on screen.

vSphere Mobile Client

The vSphere Mobile Client fling is still a work in progress but functionality keeps being added. Very useful for most VI admins.

Changelog

Version 1.2.0

  • Focused inventory (bookmark a VM and then enter focused mode by clicking the bullseye button in the header)
  • vCenter dashboard now has host and virtual machine aggregates
  • Swiping the VM card displays a screenshot, clicking on it displays an even larger image

Bug Fixes

  • Removed option to delete virtual machines
  • Improvements to the login page
  • Improvements to the events and alarms page

 

 

 

 

[API]How to successfully logoff users in Horizon

One of the things that annoy me about the Horizon admin interface is the fact that if you give a session the logoff command that this only works if the user is active aka when the desktop is not locked. With the api’s though (and Andrew implemented this in the helpdesk fling) it is possible to force a logoff. Let’s look at the available method’s first.

So we have a logoff and logoffForced. But there are also the logoffsessions and LofoffSessionsForced, I guess those let you logoff multiple sessions. this is what the extensiondata says about them.

So for the singular method’s we need a single id and for the sessions we need an array of ids. At first I will use get-hvglobalsession (yes, this works against sessions in other pod’s in a cloud pod architecture as well!) to get the id’s to show how it works. I have 5 sessions running from my desktop

$services1.Session.Session_Logoff((get-hvglobalsession | select -first 1).id)

Damn locked, let’s force this bastard from his desktop.

$services1.Session.Session_LogoffForced((get-hvglobalsession | select -first 1).id)

Aaaand it’s gone

And to show that it works I had to make sure the first session wasn’t locked.

And now the big bang fuck all of you!

$services1.Session.Session_LogoffSessionsForced((Get-HVGlobalSession).id)

As you can see one of my users was a but slow in logging off (nested esxi with only a couple vcpu’s for that one) I have also created a script that asks for the user whom you want to logoff and which session you want to logoff in case they have multiple. It’s not the cleanest code that I have written but it works 🙂

$hvserver1=connect-hvserver servername -user user -domain domain -password passwords
$Services1= $hvServer1.ExtensionData

$username= Read-Host "Which user do you want to logoff? (no wildcards needed, part of the name is enough)"

$queryService = New-Object VMware.Hv.QueryServiceService
$userdefn = New-Object VMware.Hv.QueryDefinition
$userdefn.queryEntityType = 'ADUserOrGroupSummaryView'
$userfilter1= New-Object VMware.Hv.QueryFilterContains
$userfilter1.membername='base.name'
$userfilter1.value=$username
$userfilter2= New-Object VMware.Hv.QueryFilterEquals
$userfilter2.membername='base.group'
$userfilter2.value=$False
$userfilter=new-object vmware.hv.QueryFilterAnd
[email protected]($userfilter1, $userfilter2)
$userdefn.filter=$userfilter
$users=($queryService.QueryService_Create($Services1, $userdefn)).results

$menu = @{}
for ($i=1;$i -le $users.count; $i++){ 
    Write-Host "$i. $($users[$i-1].base.name)" 
    $menu.Add($i,($users[$i-1].id))
}
[int]$ans = read-host "Please select the correct user"
$user=$menu.Item($ans)

$GlobalSessionQueryService = new-object VMware.Hv.GlobalSessionQueryServiceService
$sessionfilterspec=new-object vmware.hv.GlobalSessionQueryServiceQuerySpec
$sessionfilterspec.user=$user
$sessions=($GlobalSessionQueryService.GlobalSessionQueryService_QueryWithSpec($services1, $sessionfilterspec)).results

$menu = @{}
for ($i=1;$i -le $sessions.count; $i++){ 
    Write-Host "$i. $($sessions[$i-1].namesdata.basenames.MachineOrRDSServerName)" 
    $menu.Add($i,($sessions[$i-1].id))
}
[int]$ans = read-host "Please select the correct VDI Desktop"
$session=$menu.Item($ans)

$Services1.Session.Session_Logoffforced($session)
$queryService.QueryService_DeleteAll($services1)

This script forces the logoff for the sessions since I haven’t been able yet to find where the desktop status (locked or not) is visible.

Updates to the VMware Horizon Helpdesk fling

Today a new version has been released of the VMware Horizon Helpdesk fling by Andrew Morgan. One big change is that the Helpdesk license isn’t required anymore so at least a part of the functionality is available to owners of advanced or standard Horizon licenses.

the entire changelog:

Version 1.4.0.1

  • No longer requires a helpdesk license! Yay!
  • Added the ability to interact with vCenter machines
  • Added the ability to open vCenter VM consoles
  • Added the ability to perform bulk machine actions
  • Added the ability to perform refresh / recompose tasks directly from helpdesk.
  • Fixed performance issues with multiple windows open (see single instance).
  • Fixed a crash when logon durations could not be accessed.
  • Added polling to allow logon durations to be received if notavailable when the session page is requested.
  • Fixed a crash in the ending of processes.
  • Fixed a metric ton of bugs with delegated administration.
  • Fixed a memory leak in the tray icon menu, of all places.
  • Removed the logon page graphic as it was to much of a pain to change it’s colour when changing themes
  • Fixed some layout issues when changing themes.
  • Removed empty sites from the viewon the change pod tray menu.
  • Added preliminary support for Horizon 7.9.

 

Let’s look into some of the new options (will do the options without the helpdesk license last)

Added the ability to interact with vCenter machines 

From the pool view you’ll see an extra button for vCenter actions

And that will give these options

These all speak for themselves in functionality.

Added the ability to open vCenter VM consoles 

Open VM console will give an popup that asks for vCenter credentials.

Hit logon and a vrmc client should start if it’s installed

Added the ability to perform bulk machine actions 

The vCenter actions above can be done against multiple vm’s but also the various actions from View itself

Added the ability to perform refresh / recompose tasks directly from helpdesk. 

No longer requires a helpdesk license! Yay! 

when you use the std license the biggest difference is that you can’t view any specifics inside sessions since that’s all limited to the helpdesk license.
