Here is a custom script I made to check HP Onboard Administrators, Netapp Controllers, and vCenter servers for health issues in Powershell. Cheers!

This relies on a few things first:
VMWare PowerCLI 5.5+
Netapp DataOnTap 4.0 modules
HP OA Powershell Cmdlets to function properly.

If you want to capture VM Snapshot alarms you must create an alarm in your vCenters called “VMSnapshot Running” . I personally set mine to if the snapshot is 2GB or larger, trigger the alarm.

You must export any credentials that are not fully integrated into your AD domain. I export $nacred, and $oacred with export-clixml, and then import those creds into the function upon load time. You would need to add a vCenter cred, and use -Credential $vccred (or whatever your variable is called) on the vmware piece if that is what your environment requires.
