Powercli get vmware alarm

#get alarm info of multiple host server
Get-AlarmDefinition -Server Server1, Server2

#to get all the server alarm of a vcenter use  below script.
$alrm=get-vmhost
foreach($host in $alrm)
{
Get-AlarmDefinition -Server $host.name
}

#to get information of specific alarm, it will Extract all PowerCLI supported alarm actions for the default alarm "Host processor status".

Get-AlarmDefinition -Name "Host processor status" | Get-AlarmAction -ActionType "ExecuteScript", "SendSNMP", "SendEmail"

#Extract the alarm actions for the default alarm "Host processor status" by specifying the alarm by name.

Get-AlarmAction -AlarmDefinition "Host processor status" -ActionType "SendSNMP" -Server 'server IP'


#Get-AlarmDefinition is a typical PowerCLI getter.
#It returns all the alarms defined on the vCenter Servers you’re connected to.
Get-AlarmDefinition # This will return all the defined alarms on the servers you’re connected to

#This will return all the disabled alarm definitions with names starting with “virtual machine”
Get-AlarmDefinition -Name "virtual machine*" -Enabled $false

#This will return all alarms that apply to the host “hostname”.
#This includes alarms defined on this host and alarms inherited from the parent entity, or from any ancestors in the inventory hierarchy.
Get-VMHost hostname | Get-AlarmDefinition

#Here’s how you can modify an alarm definition:

#This will rename the alarm to “Host memory” and disable it
Get-AlarmDefinition "Host memory status" | Set-AlarmDefinition -Name "Host memory" -Enabled $false

#The main part of the alarm definitions you can manage is an alarm’s actions configuration.
#You can create an alarm action this way:
#This will create a send email action which will be triggered once when the alarm state changes from warning (yellow) to alert (red)
Get-AlarmDefinition "Host storage status" | New-AlarmAction -Email -To “me@mycompany.com” -Subject "Host storage shortage"

H#ere is how you can add another action trigger, which will fire earlier – when the alarm state changes from normal (green) to alert (yellow):
#Get the action we previously created
$action = Get-AlarmDefinition "Host storage status" | Get-AlarmAction -ActionType SendEmail

#Add a new repeating trigger to the action
$action | New-AlarmActionTrigger -StartStatus Green -EndStatus Yellow –Repeat

#You can also set the interval at which the action is repeated:
#This will configure the send email action to repeat once a day (as long as the alarm is in the yellow state)
Set-AlarmDefinition "Host storage status" -ActionRepeatMinutes (60 * 24)

#Finally you may want to remove certain alarm actions. You can do it this way:
$action = Get-AlarmDefinition "Host storage status" | Get-AlarmAction -ActionType SendEmail
Remove-AlarmAction -AlarmAction $action

#This is what you can do with the newly introduced cmdlets.
#The PowerCLI team has decided that the rest of the alarm functionality will not be reconfigured often enough to add cmdlets for the task.
#However you can always gain full control over the situation through the alarm’s View object.
#Here’s how you can change alarm configuration that is not available to change through the cmdlets:
#Get the alarm’s view
$alarmDefinition = Get-AlarmDefinition "Host storage status"

$alarmSpecification = $alarmDefinition. ExtensionData

#Make the desired alarm configuration changes
$alarmSpecification. Description="advanced-set description…..”

#Update the alarm

$alarmView = Get-View $alarmSpecification.Alarm

$alarmView.ReconfigureAlarm( $alarmSpecification )
