Check HP Management Agents with PowerCLI

Checking on the existence of HP Management Agents on your ESX hosts and/or their version is rather easy with PowerCLI.

 

Connect to your vCenter hosts using the Connect-VIServer cmdlet (remember that you can connect to multiple servers!).

Run the following piece of code to check to HP Agents:

$ESXHosts = Get-View -ViewType "HostSystem" -Property Name, Runtime.HealthSystemRuntime.SystemHealthInfo.NumericSensorInfo

[PSObject[]] $objOutput = @()

Foreach ($ESXHost in $ESXHosts)

{

    $lobjHPAgent = $ESXHost.Runtime.HealthSystemRuntime.SystemHealthInfo.NumericSensorInfo | Where-Object {$_.Name -like "*hp-agents-config*"}

    If ($lobjHPAgent -ne $null)

    {

        $lstrHPAgentVersion = $lobjHPAgent.Name.SubString($lobjHPAgent.Name.IndexOf(" ", 1) + 1)

        $lstrHPAgentVersion = $lstrHPAgentVersion.SubString(0, $lstrHPAgentVersion.IndexOf("@"))

    }

    Else

    {

        $lstrHPAgentVersion = "Not Installed"

    }

    $objESX = New-Object PSObject -Property @{Name = $ESXHost.Name;Version = $lstrHPAgentVersion}

    $objOutput += $objESX

}

$objOutput

This gives you a nice output like this:

The code might not be the shortest one, but it’s fast and gives you an Object that you can pipe through Sort-Object, Format-Table, …
