export / store / delete / import alarms on many datacenters object

[TCPvmadmin]

Hi there,

I read many thing and see scripts from LucD but I still have an issue about my need.

Actually I have Alarm defined on my vCenter object and I have 5 Datacenters on this vCenter.

Each Datacenter are managed by differents support team.

We need :

- Copy / export Alarms from vCenter objects and delete them

- import these alarms to each differents datacenter object

If anyone can help us , maybe based on LucD script because I'm not able to understand all LucD's alarm script.

Thanks for your help.

Hi Jeremy, which script do you refer to ?

[TCPvmadmin]

Hi Luc,

This one : http://www.lucd.info/2010/02/20/alarms-moving-them-around/ I need same kind of scripts but moving theses alarms from vCenter object to a Datacenter and after that re execute it to copy on other datacenter object.

[LucD]

It's a matter of setting the $From and $To parameters of the function correctly.

The following is an updated version of my script that copies alarms from the vCenter root to 2 datacenters.

Set-Variable -Name alarmLength -Value 80 -Option "constant"

function Move-Alarm{
  param($Alarm, $To, [switch]$DeleteOriginal = $false)

  $alarmObj = Get-View $Alarm
  $alarmMgr = Get-View AlarmManager
  if($deleteOriginal){
    $alarmObj.RemoveAlarm()
  }
  else{
    $updateAlarm = New-Object VMware.Vim.AlarmSpec
    $updateAlarm = $alarmObj.Info
    $oldName = $alarmObj.Info.Name
    $oldState = $alarmObj.Info.Enabled
    $oldDescription = $alarmObj.Info.Description
    $suffix = " (moved to " + ([string]($to | %{$_.Name + ","})).TrimEnd(",") + ")"
    if(($oldName.Length + $suffix.Length) -gt $alarmLength){
      $newName = $oldName.Substring(0, $alarmLength - $suffix.Length) + $suffix
    }
    else{
      $newName = $oldName + $suffix
    }
    $updateAlarm.Name =  $newName
    $updateAlarm.Enabled = $false
    $updateAlarm.Description += ("`rOriginal name: " + $oldName)
    $updateAlarm.Expression.Expression | %{
      if($_.GetType().Name -eq "EventAlarmExpression"){
        $_.Status = $null
        $needsChange = $true
      }
    }

    $alarmObj.ReconfigureAlarm($updateAlarm)

    $alarmObj.Info.Name = $oldName
    $alarmObj.Info.Enabled = $oldState
    $alarmObj.Info.Description = $oldDescription
  }

  $newAlarm = New-Object VMware.Vim.AlarmSpec
  $newAlarm = $alarmObj.Info
  $oldName = $alarmObj.Info.Name
  $oldDescription = $alarmObj.Info.Description
  foreach($destination in $To){
    if($To.Count -gt 1){
      $suffix = " (" + $destination.Name + ")"
      if(($oldName.Length + $suffix.Length) -gt $alarmLength){
        $newName = $oldName.Substring(0, $alarmLength - $suffix.Length) + $suffix
      }
      else{
        $newName = $oldName + $suffix
      }
      $newAlarm.Name = $newName
      $newAlarm.Description += ("`rOriginal name: " + $oldName)
    }
    $newAlarm.Expression.Expression | %{
      if($_.GetType().Name -eq "EventAlarmExpression"){
        $_.Status = $null
        $needsChange = $true
      }
    }

    $alarmMgr.CreateAlarm($destination.MoRef,$newAlarm)
    $newAlarm.Name = $oldName
    $newAlarm.Description = $oldDescription
  }
}

$alarmMgr = Get-View AlarmManager

$from = Get-Folder -Name "Datacenters"
$to1 = Get-Datacenter -Name "DC1" 
$to2 = Get-Datacenter -Name "DC2" 

$alarms = $alarmMgr.GetAlarm($from.ExtensionData.MoRef)
$alarms | % {
  Move-Alarm -Alarm $_ -To $to.ExtensionData -DeleteOriginal:$false
}

Let me know if this does what you are looking for ?

Luc ,

Thanks for your time and effort I will try this right now and give you a feedback !

[TCPvmadmin]

It's not working at all , I have these kind of error :

The script needs to store all vCenters alarm , delete them and after these operation copy them on each datacenter.

[LucD]

Did the script get the alarms in $alarms ?

If there are no alarm definitions at the vCenter root, this variable will be empty.

[TCPvmadmin]

Yes there still have alarm in vCenter object and I can't tell you if $alarm variable is not empty I have any debuging tool (like PowerGUI) on my vCenter test lab.

Could you confirm that Get-Folder -Name "Datacenters" mean my vCenter objects ?

[LucD]

You could just add an extra line to the script with

$alarms | Select @{N="Name";E={$_.Info.Name}}

on it.

That way you should be able to see if some alarms are in the $alarms variable

[TCPvmadmin]

You'r right, $alarm variable is always empty

[LucD]

Do you see any alarm definitions in the vCenter root (datacenters) when you look with the vSphere client ?

The $From variable can be populated with a pointer to another VI Container. The script will handle that as well

[TCPvmadmin]

Yes I see definition Alarm on vCenter root object.

Today I will install a script editor in my lab to point what's happened exactly I will give you a feedback.

[TCPvmadmin]

Luc,

I just ran the script with my script editor and now the script seem's working better but there is still error.

Actually the script stop at :

$newAlarm.Description = $odlDescription

The property Description cannot be found on this object

It's seems this error doesn't occur for every object (Alarm description) maybe due to description lenght ?

I'm currently try to "debug" but the script is too complex for me :smileyconfused:

[LucD]

I suspect that could be a typo, that should be

$newAlarm.Description = $oldDescription

[TCPvmadmin]

Yes sorry it's my typo error.

I think find the beggining of the error, I attached a debug text file and the $alarms array is not empty but there is an error here :

  $alarms | Select @{N="Name";E={$_.Info.Name}}

There is any property existing in your select if you make a $alarms | get-member are you sure about that ?

$alarms | get-member

TypeName: VMware.Vim.ManagedObjectReference

Name        MemberType Definition

Thanks for your help

[LucD]

My mistake. The $alarms variable contains a series of MoRefs (pointers) to the Alarm objects.

So that should be

Get-View $alarms | Select @{N="Name";E={$_.Info.Name}}

Sorry about that

[TCPvmadmin]

I will try now and get you a feedback thanks !

Edit : I don't understand where I'm supposed to change this line. Could you repaste me the good script please ?
