Quite frequently there are questions in the VMTN PowerCLI Community for scripts that report on the tasks that ran in a vSphere environment.
The PowerCLI pssnapin provides a Get-Task cmdlet, but that only provides information about the recent tasks. An alternative is to use the Get-VIEvent cmdlet and extract all the TaskEvent entries.
But why not use the TaskHistoryCollector and it’s methods ? It provides many filtering options, and since this filtering is done in vSphere itself, this way of working is inherently much faster than using a filter in your script.
In analogy with the Get-VIEventPlus function, I published in my Get the vMotion/svMotion history post, here is the Get-TaskPlus function !

In a previous post, called Events, Dear Boy, Events – Part 2, I mentioned that some tools/add-ons use a special event type called ExtendedEvent. Two classic examples are the Converter and the Update Manager. If you want to compile a report for any these tools it’s important to understand what is available in the extended events they produce.
If you want to know if there are any other tools/add-ons in your vSphere environment that produce extended events, then you can use the first script from the Events, Dear Boy, Events – Part 2 post to get a complete list of all available extended events.
In this post I’ll show how to use the Converter extended events.

There was an interesting question in the PowerCLI Community on how to use the -RunAsync parameter. The user wanted to create a number of new guests and start each guest once the creation was complete. This can be done rather easily by using a New-VM cmdlet and piping the result to the Start-VM cmdlet.
Only problem was, the creation of the new guests was done in Async mode.
That’s where the Get-Task cmdlet and the use of a hash table come in handy.
