2. Modify the name and the description of a selected alarm definition, and enable the alarm.

   Get-AlarmDefinition -Name AlarmDefinition | Set-AlarmDefinition -Name AlarmDefinitionNew -Description 'Alarm Definition Description' -Enabled:$true

3. Create an alarm action email for the renamed alarm definition.

   Get-AlarmDefinition -Name AlarmDefinitionNew | New-AlarmAction -Email -To '[email protected]' -CC @('[email protected]', '[email protected]') -Body 'Email text' -Subject 'Email subject'

4. Create an snmp alarm action.
