I searched this community and the greater internet and could not find something that did this so I made it. It’s a very simple script. Give the user who is running it permission to run icingacli, and give the script the name of an Icingaweb2 module, and the script checks the github release versions against icingacli to see if the latest version is running.
Thanks Icinga community for all the work you have done over the years to make this monitoring software! I have used it happily for over a decade.
