Every system administrator knows systemd. Developed by Lennart Poettering and freedesktop.org, systemd comes as a very handy initialization tool for administrating Linux services and handling dependencies. Most of the modern tools are shipped as systemd services and managed from there.
But what happens when one of the services fails? Most of the time, you discover it when the damage is already done.
Today, we are going to build a complete dashboard that monitors systemd services in realtime. It will provides us with active, inactive and failed services, and even raise alerts to Slack when one fails!
