A Telegraf plugin to check Debian for package updates.
This plugin runs continuously and prints an output in the interval requested by Telegraf.
In addition, the ouput can be triggered externally, e.g. during apt update to get the latest status in almost real time.
The Debian wiki is queried to check the LTS status.
Install curl.
To make this plugin useful you need a way to keep your package sources up to date.
You can use unattended-upgrades to run apt update on a regular basis.
To trigger the plugin to collect new stats after an apt update, create a Post-Invoke configuration.
You can copy 99telegraf to /etc/apt/apt.conf.d/99telegraf or use it as example.
Telegraf can be configured like this:
[[inputs.execd]]
command = ["/bin/sh", "/opt/telegraf/telegraf-apt.sh"]
