Is there a plugin, container or app that can send a notification (email or other) when an VM has stopped?

Hi, I think it's possible with qemu hooks and notify command available in unraid.

Search about hooks for qemu in unraid and create one to push a notification (setup the parameters in unraid), something like this (not tested):

 

#!/bin/bash

if [[ $1 == "NameOfVM" ]] && [[ $2 == "stopped" ]]
then
  /usr/local/emhttp/webGui/scripts/notify -i normal -s "VM stopped"
fi

 

Replace NameOfVM with your vm name.

 

Info about notify command:

# /usr/local/emhttp/webGui/scripts/notify
notify [-e "event"] [-s "subject"] [-d "description"] [-i "normal|warning|alert"] [-m "message"] [-x] [-t] [add]
  create a notification
  use -e to specify the event
  use -s to specify a subject
  use -d to specify a short description
  use -i to specify the severity
  use -m to specify a message (long description)
  use -x to create a single notification ticket
  use -t to force send email only (for testing)
  all options are optional
notify init
  Initialize the notification subsystem.
notify smtp-init
  Initialize sendmail configuration (ssmtp in our case).
notify get
  Output a json-encoded list of all the unread notifications.
notify archive file
  Move file from 'unread' state to 'archive' state.

 

Would anyone be willing to explain how to do this to a noob? I've done a ton of Googleing and for the life of me just cannot figure this out. 

 

I'm currently running Home Assistant as a VM on Unraid. It works great, but occasionally it will crash. The only way I find out is when some sort of automation won't work or when the wife yells at me about something not working. If I could get a notification when this happens I could restart Home Assistant before anyone runs into issues. 

 

Thanks for you help!

I would be interested in doing the same thing.  There must be an easy way to notify when a VM goes down?

Here is a simple item you can create in this directory, You will need to chmod +x the file.

 

root@computenode:/etc/libvirt/hooks/qemu.d# cat Notify 
#!/usr/bin/env php

<?php


if ($argv[2] == 'started' || $argv[2] == 'stopped'){
      shell_exec("/usr/local/emhttp/webGui/scripts/notify -i normal -s \"VM {$argv[1]}\" -d \"".ucfirst($argv[2])."\"  >/dev/null 2>&1 & disown") ;
}
?>
root@computenode:/etc/libvirt/hooks/qemu.d#
