modify alarm setting (actions)

[qwert1235]

Hello:

I need to modify settings for my existing alarm by script. I need to add SNMP action to specific alarm (I know how to filter by name).

Can somebody please help me with it?

Thanks,

qwert

Have a look at my scripts in CreateAlarm not (always) compatible with the vSphere client.

In there I use a SendSNMPAction action.

Luc,

I know how to create Alarm that does NOT exist yet with action - thanks to your post (see attachment).

However, I cannot figure out how I can just add action to the existing alarm...

I guess, I have to use EditAlarm or ReconfigureAlarm, but have problem with it...

I really appreciate the help.

Thanks,

qwert

You have to use the ReconfigureAlarm method

Something like this

$tgtAlarmName = <alarm-name>
$alarmMgr = Get-View AlarmManager
$alarms = $alarmMgr.GetAlarm($null)
$alarms | %{
	$alarm = Get-View $_
	if($alarm.Info.Name -eq $tgtAlarmName){
		$spec = New-Object VMware.Vim.AlarmSpec
		$spec.Action = $alarm.Info.Action
		$spec.Expression = $alarm.Info.Expression
		$spec.Setting = $alarm.Info.Setting
		$spec.Name = $alarm.Info.Name
		$spec.Description = $alarm.Info.Description
		$alarmTrigger = New-Object VMware.Vim.AlarmTriggeringAction
		$alarmTrigger.TransitionSpecs =  New-Object VMware.Vim.AlarmTriggeringActionTransitionSpec
		$alarmTrigger.TransitionSpecs[0].StartState = $spec.Action.Action[0].TransitionSpecs[0].StartState
		$alarmTrigger.TransitionSpecs[0].FinalState = $spec.Action.Action[0].TransitionSpecs[0].FinalState
		$alarmTrigger.Action = New-Object VMware.Vim.SendEmailAction
		$alarmTrigger.Action.toList = "luc.dekens@lucd.info"
		$alarmTrigger.Action.CcList = ""
		$alarmTrigger.Action.Subject = "Alarm subject"
		$alarmTrigger.Action.Body = ""
		$spec.Action.Action += $alarmTrigger
		$alarm.ReconfigureAlarm($spec)
	}
}

I hope this puts you on the right track.

Luc,

Thank you very much for your help. Unfortunately, it’s still does not work.

You code gives error “$alarmTrigger.TransitionSpecs[0].StartState = $spec.Action.Action[ <<<< 0].TransitionSpecs[0].StartState”

Also, looks like I have to add line $spec.Enabled = $alarm.Info.Enabled for the alarm to stay enabled.

I tried to modify the code and in my last draft it looks like this:

http://Reflection.Assembly::LoadWithPartialName("vmware.vim")

$svcRef = new-object VMware.Vim.ManagedObjectReference

$svcRef.Type = "ServiceInstance"

$svcRef.Value = "ServiceInstance"

$serviceInstance = get-view $svcRef

$entity = Get-View (Get-Folder -Name "Datacenters").ID $alarmMgr = get-view $serviceInstance.Content.alarmManager

$tgtAlarmName = "TEST_ALARM"

$alarmMgr = get-view $serviceInstance.Content.alarmManager

$alarms = $alarmMgr.GetAlarm($null)

$alarms | %{

$alarm = Get-View $_

if($alarm.Info.Name -eq $tgtAlarmName){

$spec = New-Object VMware.Vim.AlarmSpec

$spec.Expression = $alarm.Info.Expression

$spec.Setting = $alarm.Info.Setting

$spec.Name = $alarm.Info.Name

$spec.Enabled = $alarm.Info.Enabled

$spec.Description = $alarm.Info.Description

$spec.Action = New-Object VMware.Vim.GroupAlarmAction

$action = New-Object VMware.Vim.AlarmTriggeringAction

$action.Action = New-Object VMware.Vim.SendSNMPAction

$trans = New-Object VMware.Vim.AlarmTriggeringActionTransitionSpec

$trans.StartState = "yellow"

$trans.FinalState = "red"

$action.TransitionSpecs += $trans

$alarm.ReconfigureAlarm($spec)

}

}

But when I am running it I got error on my last line:

“Exception calling "ReconfigureAlarm" with "1" argument(s): "Not initialized: vim.alarm.AlarmAction[] action" $alarm.ReconfigureAlarm <<<< ($spec)”

Can you please point me what to mistakes in this code?

Thanks,

qwert

I tested with an alarm that had 1 action (send email) and the adapted script below seems to work.

$entity = Get-View (Get-Folder -Name "Datacenters").ID 
$alarmMgr = get-view AlarmManager

$tgtAlarmName = "Test Alarm"

$alarms = $alarmMgr.GetAlarm($null)
$alarms | % {
	$alarm = Get-View $_
	if($alarm.Info.Name -eq $tgtAlarmName){
		$spec = New-Object VMware.Vim.AlarmSpec
		$spec.Expression = $alarm.Info.Expression
		$spec.Setting = $alarm.Info.Setting
		$spec.Name = $alarm.Info.Name
		$spec.Enabled = $alarm.Info.Enabled
		$spec.Description = $alarm.Info.Description

		$spec.Action = New-Object VMware.Vim.GroupAlarmAction
		$action = New-Object VMware.Vim.AlarmTriggeringAction
		$action.Action = New-Object VMware.Vim.SendSNMPAction
		$trans = New-Object VMware.Vim.AlarmTriggeringActionTransitionSpec
		$trans.StartState = "yellow"
		$trans.FinalState = "red"
		$action.TransitionSpecs += $trans

		$spec.Action.Action = $alarm.Info.Action.Action
		$spec.Action.Action += $action
		
		$alarm.ReconfigureAlarm($spec)
	}
}

Note1: you don't need to do the LoadWithPartialName anymore since VITK 1.5

Note2: for the AlarmManager, the Get-View has a direct pointer. No need to go via ServiceInstance anymore.

Note3: first I copy over the existing actions from $alarm.Info.Action and then I add the new $action

Hey LucD, can u help me creating the VI Java equivalent of this ?

Here is my code :

}

exp.setEventType("DatacenterRenamedEvent");

exp.setObjectType("Datacenter");

exp.setStatus(ManagedEntityStatus.yellow) ;

return exp;

}

}

</Code>

Please help

Thanks in advance.

Sorry to disappoint you, but my Java knowledge is $null.

Why don't you try your luck in the VI Java forum ?

[apapap]

Ok. Thanks for the quick response.

[qwert1235]

Luc,

Can you please help me figure out what am I missing on my server that preventing me to run "Get-View AlarmManager"?

Here is the error I am getting:

PS C:\temp> $alarmManager = Get-View AlarmManager

PS C:\temp>

I am using vSphere PowerCLI 5.0.1.4431 and PowerShell 2.0.  It's working for me on another server wher I am running the same version of PowerCLI and PowerShell... I think I am missing something; but what?

Thank you,

qwert

[LucD]

Are you perhaps connected to a vCenter ?

That error normally appears when connected to an ESXi server.

Btw, in the current PowerCLI version there is no need anymore to use the SDK methods to change Alarm actions.

There are now cmdlets for that, see New-AlarmAction.

[qwert1235]

Luc,

Thanks a lot!

No, I connected to VC, not to ESX host, but you were right it was connection issue.

Thanks again,

qwert
