This is another version i created that just grabs all alarms and sets email trigger. Note that it will delete all the current triggers (so ensure you dont have SNMP traps etc that you need)


# v3 : grab all alarms from vcenter (so should work all versions) and use these for alarm variables
# Usage ;
# Please manually connect to vCenter, use "Connect-VIServer" -- this promotes usernames and passwords not beings saved with script.
# Any alarm that is currently active will send email alert -- please confirm appropriate values for tiggers before running this script.

#Set Notification emails here;
$MailTo= “[email protected]”

#define alarms to be set;
$Alarms = Get-AlarmDefinition | sort Name | select name | ft -HideTableHeaders

foreach ($Alarm in $Alarms)
{
# Delete Trigger;
Get-AlarmDefinition -Name “$Alarm” | Get-AlarmAction | Remove-AlarmAction -Confirm:$false

# Create Trigger;
Get-AlarmDefinition -Name “$Alarm” | New-AlarmAction -Email -To “$MailTo”
}

UPDATE : I generally use the following script now. Less to maintain, and covers any alarms that have not been managed.

# Author : Darren Taylor
# v5 : grab all alarms from vcenter (so should work all versions) and use these for alarm variables
# Usage ;
# Please manually connect to vCenter, use “Connect-VIServer” — this promotes usernames and passwords not being saved with script.
# Any alarm that is currently active will send email alert — please confirm appropriate values for tiggers before running this script.
#
# Note ;
# This script needs to be modified to exclude alarms that are not critical (exclusive rather than inclusive)
# Once Exceptions list is updated, re-run script.

# ——————- VARIABLES ————————-

# These are the names of the alarms to ignore — i.e. do NOT setup email alert
