Attach alarm to datastore

markdjones82 · ‎03-12-2013

So, we ahve a global alarm to alert on disk space, but we have a few that are above that and keep alerting. I'd like to remove the global alarm and set it on each object.

I was looking at the powercli commandlets and only see a way to modify the definitions but not set hte alarm on an object. Is this possible or will I need to get some onyx code?

No cmdlets for that I'm afraid.

But you can move/copy that alarm. Have a look at Alarms – Moving them around

Thanks, so I have to create the exact same alarm on all of them so I decided to just get the code after creating the alarm through the gui. I then deleted the alarm and tried to run it, but it is saying that the alarm has been deleted or not fully created. It's like it has a cached copy of it somewhere?

Afaik there is no cached copy. If the alarm is deleted, it is gone.

Can you add a check before calling CreateAlarm ?

Something like

Get-AlarmDefinition -Name "DatastoreSpace-$datastore.name"

If this returns an object, there must be an alarm with the same name present.

I added a check but there is no alarm with that name 😕 here is the ouput. Any ideas?

I did remove the .name part on the datastore name because it looks like it outputs the name only when referencing the variable?

$datastore = Get-Datastore datastore1234

 $checkalarm = Get-AlarmDefinition -Name  "DatastoreSpace-$datastore"
if ($checkalarm)
{
  Write-Host "Alarm is already defined!"
  }
else{

One more update, I tried it with random numbers at end of the name 12345678 and I receive same error

Maybe I have something wrong with the code I got. I'll check onyx again and make sure I coped it correctly.

Have a look in the vpxd log on your vCenter.

Sometimes you'll find a better indication of what is missing in the specs in that log.

Aha! It can't find the object. I found my typo, I had the object in quotes instead of just the variable

$entity.Value = "$datastore.extensiondata.moref.value"

$entity

.Value = $datastore.extensiondata.moref.value
