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.
The high level steps are pretty straight forward.
- Add a wrapper script which creates the
apt.promfile format for you.
- Install the apt hook.
- Enable the text file collector and point it to your directory with the
- Scrape the Node_Exporter endpoint with Prometheus
- Install the Grafana dashboard
I’ve collected the scripts and a Grafana dashboard you can use in the apt-prometheus repository.
Feel free to fork - merry x-mas and have fun.
