Managing alarms

To manage the different aspects of an alarm, we can use the following cmdlets:

• Get-AlarmAction
• New-AlarmAction
• Remove-AlarmAction
• Get-AlarmDefinition
• Set-AlarmDefinition
• Get-AlarmActionTrigger
• New-AlarmActionTrigger
• Remove-AlarmActionTrigger

There is no direct cmdlet available to create an alarm. We can create an alarm using the vSphere APIs, which we will cover in a later chapter. So, in this section, we will cover how to define and manage the different aspects of an existing alarm.

An alarm has main three parts: an alarm definition, alarm action, and alarm action trigger.
