How can I get triggered alarms using PowerCLI?

Question

In vSphere Client on a VM host in the Alarms tab there is a view of Triggered Alarms.

How can I get those alarms using PowerCLI?

Solution 1

To find all vmhosts with alarm status = "red", I expanded on this.

#
# Find all hosts with triggered alarms in "Red" state
#
$esx_all = Get-VMHost | Get-View
$Report=@()
foreach ($esx in $esx_all){
    foreach($triggered in $esx.TriggeredAlarmState){
        If ($triggered.OverallStatus -like "red" ){
            $lineitem={} | Select Name, AlarmInfo
            $alarmDef = Get-View -Id $triggered.Alarm
            $lineitem.Name = $esx.Name
            $lineitem.AlarmInfo = $alarmDef.Info.Name
            $Report+=$lineitem
        } 
    }
}
$Report |Sort Name | export-csv "c:\temp\ESX-Host-Red-Alarms.csv" -notypeinformation -useculture
Invoke-item "c:\temp\ESX-Host-Red-Alarms.csv"

Solution 2

this is what i use.

$esx = Get-VMHost $vmhost | Get-View
foreach($triggered in $esx.TriggeredAlarmState){
  $alarmDef = Get-View -Id $triggered.Alarm
  Write-Host $alarmDef.Info.Name
}

I had tried that but it never returned anything at all, while the "Triggered Alarms" view in vSPhere Client showed my triggered alarm. (I created a triggered alarm based on a VM being used more than 1% CPU over 30 seconds as a test alarm.)

You may need to look at the vm view in that case. I am not sure if vm alarms are included in the vmhost view.

You can format your code as it is formatted now (I've done it for you) by indenting with 4 spaces.
