APT Monitoring with Prometheus

As soon you run a Linux server, you need to make sure your systems are up-to-date. It would also be handy to know if you had Kernel upgrades which require a reboot of the system to get applied.

I came across a blog post from Tom Henderson which provided a solution using the Node_Exporter with Prometheus. The way he solved this is pretty slick. I had to tweak the scripts a bit to get it running. He integrated an APT hook which runs a command on apt update and after installing packages. The hooks create a Prometheus file which can be easily shipped with the Node_Exporter.
