All my failed Power supplies using Powershell

Sometimes you just want to see all the systems that have a certain problem, like failed power supplies or all systems where free disk space is low.


Here is a bit of Powershell to list any server where the Health State of the HP Proliant SNMP Management Pack Power supply Class is in an Error state.


$ClassID = "HewlettPackard.Servers.ProLiant.SNMP.HPProLiantSNMPPowerSupplies"
$Class = get-monitoringclass -name:$ClassID
$ClassInstances = get-monitoringobject -monitoringclass:$Class
$Errors = $ClassInstances | where {$_.HealthState -eq "Error"}
Foreach ($Server in $errors)
{
$server."[HewlettPackard.Servers.HPHealthCollection].ServerName"
}


Free Space /Availability of Logical Disks on Server 2003


$ClassID = "Microsoft.Windows.Server.2003.LogicalDisk"
$Class = get-monitoringclass -name:$ClassID
$ClassInstances = get-monitoringobject -monitoringclass:$Class
$Errors = $ClassInstances | where {$_.HealthState -eq "Error"}
Foreach ($Server in $errors)
{
$Server.Path + "," + $Server.name
}


A good way to catch issues where the alerts may have been missed.

Of course you can just use the Discovered Inventory View on the Operations Console and change the target type to Windows Server 2003 Logical Disk but the console has no easy way to get this data out except a one by one copy and paste.
