give the cockpit a go. It won't use system resources, but gives good light way to manage server and see stuff. $PKGMGR install -y cockpit*&&systemctl enable --now cockpit.socket. Then up to yout network, but if can't open firewall, take ssh -L 9090:localhost:9090 $host and firefox https://localhost:9090 

 checkmk looks interesting. Last week I did demo with dynatrace (together with ansible eda), that was some heavy duty stuff.
