So I think I’m going to have a stab at creating a custom Freshservice plugin, ripping the Nagios integration apart - we are migrating from Nagios, so it makes it a bit easier, and Nagios uses the same OMD backend as Checkmk. With a few tweaks to alert payloads in Fresh, and tweaks to the JSON notifications sent via a custom bash script, I think this can work. Will get back with how I got on, but will take some time to test as I get to grips with it.
