PowerCLI: Getting host alarms

Yesterday I wrote a post about getting vm alarms through PowerCLI. Today it’s time for getting host alarms 🙂
The code is very similar to the one for getting vm alarms, since they both use get-view to grab all info:

$VMHosts = Get-View -ViewType HostSystem -Property Name,OverallStatus,TriggeredAlarmstate
$FaultyVMHosts = $VMHosts | Where-Object {$_.TriggeredAlarmState -ne "{}"}

$progress = 1
$report = @()
if ($FaultyVMHosts -ne $null) {
   foreach ($FaultyVMHost in $FaultyVMHosts) {
       foreach ($TriggeredAlarm in $FaultyVMHost.TriggeredAlarmstate) {
           Write-Progress -Activity "Gathering alarms" -Status "Working on $($FaultyVMHost.Name)" -PercentComplete ($progress/$FaultyVMHosts.count*100) -Id 1 -ErrorAction SilentlyContinue
           $alarmID = $TriggeredAlarm.Alarm.ToString()
           $object = New-Object PSObject
           Add-Member -InputObject $object NoteProperty VMHost $FaultyVMHost.Name
           Add-Member -InputObject $object NoteProperty TriggeredAlarms ("$(Get-AlarmDefinition -Id $alarmID)")
           $report += $object
           }
       $progress++
       }
   }
Write-Progress -Activity "Gathering alarms" -Status "All done" -Completed -Id 1 -ErrorAction SilentlyContinue

$report | Where-Object {$_.TriggeredAlarms -ne ""} 

The output will look something like this:

And here’s the function code:

function Get-VMHostAlarms
{
$VMHosts = Get-View -ViewType HostSystem -Property Name,OverallStatus,TriggeredAlarmstate
$FaultyVMHosts = $VMHosts | Where-Object {$_.TriggeredAlarmState -ne "{}"}

$progress = 1
$report = @()
if ($FaultyVMHosts -ne $null) {
   foreach ($FaultyVMHost in $FaultyVMHosts) {
       foreach ($TriggeredAlarm in $FaultyVMHost.TriggeredAlarmstate) {
           Write-Progress -Activity "Gathering alarms" -Status "Working on $($FaultyVMHost.Name)" -PercentComplete ($progress/$FaultyVMHosts.count*100) -Id 1 -ErrorAction SilentlyContinue
           $alarmID = $TriggeredAlarm.Alarm.ToString()
           $object = New-Object PSObject
           Add-Member -InputObject $object NoteProperty VMHost $FaultyVMHost.Name
           Add-Member -InputObject $object NoteProperty TriggeredAlarms ("$(Get-AlarmDefinition -Id $alarmID)")
           $report += $object
           }
       $progress++
       }
   }
Write-Progress -Activity "Gathering alarms" -Status "All done" -Completed -Id 1 -ErrorAction SilentlyContinue

$report | Where-Object {$_.TriggeredAlarms -ne ""}
