Back in 2016 I wrote a Checkmk notification script that sends messages via a Telegram Bot. Only a few years later I got around and turned it into a real Checkmk package.
After switching to Checkmk 1.6 some months ago, all I had for notifications was email. During my christmas vacation I got notifications via Telegram set up again. As part of the setup I also brought the old code into shape and finally packaged it as a real Checkmk package to make installation easier.
I once installed Checkmk into an existing Nagios installation, back then by using a plain source package. This also meant I had to take care of installing and configuring all dependencies like Apache, Nagios and PNP4Nagios. Keeping this setup working was quite tedious over the last two upgrades (1.2.4 to 1.2.6 and finally 1.2.6p16) so I decided to switch to the official Checkmk CRE packages instead. For now I switched to the rather outdated 1.2.6p16 packages to concentrate on migrating my configuration first.
