Automation

Hi,

we're currently using DRS for distribution of Windows-VMs on specific hosts within our clusters. These hosts are bundled in a DRS-Group "Windows licensed hosts" in each cluster.

For our license-management I need to report the current number of hosts (and CPUs per host) assigned to these DRS-Groups each month.

As the environment is growing bigger I want to automate this task by using a scheduled report.

How can I get a list of relevant hosts incl. physical CPUs per cluster and a total CPU-count?

We're using vSphere 5.1 and PowerCLI doesn't seem to offer a lot for DRS-Groups out of the box.

I just need to know how to get the list of hosts, I can do anything around that (adding PSModule, connection to vVenter, report per mail, etc.) by myself

Any help appreciated.

Hi Daniel,

right, PowerCLI doesn't offer much out of the box.

But there's a module you can import:

That should help ;-)

That's looking good =)

Just did my first steps using it...

PowerCLI C:\> Get-Cluster CLUSTER | Get-DrsVMHostGroup -Name '*Windows*' | select VMHost

VMHost

------

{HOST1, HOST2}

How can I iterate through this list of hosts now?

Foreach doesn't work as it's no array.

Try doing a Select -ExpandProperty VMHost

Thanks a lot that worked.
