Kibana/ES is overkill and not worth it. I have Loki, promtail and grafana setup for my 4 VMs and 2 systems. Took about a week to get dashboards and stuff going (plus geoip and worldmap plugin config for my public servers) but haven’t had to touch them in about 2 years since.
Just now heard of armcord which I’m going to give a shot on Linux here soon but looks like armcord is just a client, while this is a server as well.
