The last couple of days there was quite a bit of ThinApp news !
Time to post another ThinApp-PowerShell function.

I got an interesting question from one of my co-authors of the PowerCLI Reference book. He was looking for a method to find the port used by a VM when connected to a portgroup on a dvSwitch.
Finding the answer to that question is not too difficult, once you know which property holds the value. But while writing and testing the script, I thought that this question would be a good opportunity to show several ways and methods that you have at your disposal in PowerCLI and PowerShell, to come to a solution.
Here it goes.

Sometimes a solution to a problem is just staring you in the face.
While writing the PowerCLI book, I spent quite a bit of time on how to find which user acknowledged an alarm.
Today Eric “Scoop” Sloof launched the same question on Twitter. While I thought it was not possible, based on my past investigations, I decided to have a second look.
And of course now I found in a matter of minutes what had cost me fruitless hours before.

Another interesting feature of a dvSwitch is the ability to use bidirectional traffic shaping. Besides the outbound traffic shaping that is available on regular virtual switches, with the dvSwitches we can also have inbound traffic shaping. The traffic shaping is defined with the three known, classical values: average bandwidth, peak and burst size.
Recently there were some threads in the PowerCLI Community that asked how to do this with PowerCLI. Time to add this to our repertoire of PowerCLI dvSwitch functions.
When you’re using ThinApp to package your software packages you are bound to end up with a huge repository after some time. Of course you have documented each ThinApp package you made, but sometimes you will need to produce a quick-and-dirty report. Then it’s handy to fire up a PowerShell script, instead of reading through all the packaging documentation.
With the help of the ThinApp SDK it’s quite easy to produce such a report.
With vSphere 4.1 came 150+ new features. One of these is called Storage IO Control or SIOC.And it has been a very popular subject in the last weeks. Just a small selection of blog posts on the subject:
The only thing missing was a way to automate everything surrounding SIOC. And so I decided to write a couple of functions to fill that gap.
The VMTN Communities have always been a useful source of inspiration for writing scripts. This week, for example, there was an intriguing question raised in the Onyx Community. The user wanted to know if it was possible to monitor changes in the vSphere environment in real time.
As far as I know there is no API in the vSphere SDK to do real time monitoring. But the EventHistoryCollector can deliver something that I prefer to call nearly real time monitoring. The following script is a very basic function, written primarily to show that this principle of nearly real time monitoring works. The function displays some selected properties of each event it sees.

One of the announcements during VMworld 2010 in San Francisco that perhaps got a bit obscured by the other “big” announcements, was the release of Onyx 2.0. For those of you that hadn’t heard of Project Onyx before, this nifty little tool captures all SOAP traffic that is passed between your vSphere client or PowerCLI session and the vCenter or ESX(i) server to which you are connected.
And that’s not all, the Onyx program will translate the captured SOAP traffic into PowerShell code. This allows you to see which vSphere APIs are used and how parameter objects for these methods are constructed.
Update September 16th 2010: the Onyx Development Team has just released a new build (2.0.3910.32223) that fixes some issues when using Onyx with the PowerCLI client. Congratulations to the Onyx Development Team for this quick resolution of the problem !
On August 19th 2010 the long awaited ThinApp SDK became available.It allows you to programmatically interact with your ThinApp packages. The SDK package is foreseen to be used with Visual Studio, as can be deduced from the included merge module called ThinAppSDK.msm. The samples that come with the SDK unfortunately only show the use of the SDK with C++ and VBScript. But with a bit of fiddling it’s quite easy to use the APIs from your PowerShell environment.
This post will show you:
- how to set up the SDK for use from PowerShell
- some usage examples from PowerShell.

One of the new features that came with vSphere 4.1 was the ability to use Active Directory Authentication on ESX(i) servers for permissions, console access and ssh access.This is a great feature that you will probably want to activate on all your ESX(i) servers.
Unfortunately this new feature is not available in PowerCLI 4.1. That means you can’t set this up in your configuration scripts through a PowerCLI cmdlet. In most such cases you can fall back on one of the SDK APIs to bypass this lack of a cmdlet. But unfortunately the new “managers”, of which HostActiveDirectoryAuthentication is one, are not available in the VMware.Vim assembly either.
Rob raised this in a recent PowerCLI Community thread. Yasen, one of the PowerCLI Dev Team members, provided a bypass. To make this bypass a bit more accessible, I decided to roll it up in a PowerShell function.
