Simple self-hosted monitoring tools

Recently I need a tool to monitoring my devices, and alert me if some services goes down.

I found some softwares on internet.

I heard Grafana, Prometheus and Zabbix before but they seems too complicated to me.

I have experience with Monit before, the config was simple, it can alert via email. I will have it on my server but I wanted to try something new.

So I tried Netdata, for my needs it was simple with fancy UI but I don’t want all of its feature.

Gatus and Uptime Kuma seems fit my needs, it does the job and it has clean UI.

I will try Gatus in several days and still running Netdata for now.

After all, maybe I will go back with Monit because I don’t really want UI, just monitoring and alert.
