Observability
I run a quite large vps. now and i want to monitor it ive been using beszel an uptime kuma, does anyone know a better solution ive tried grafana an prometheous. but it was not as good as i was hoping. i saw netdata on selfh.st does anyone have expierance with that.
Depends on what youre trying to track, but prom can track whatever you want and grafana can display it. You may also want log monitoring as well, which you can also feed in - grafana is just display.
The metrics you want to look at are the big question though.
Prometheus is mostly for regularly collected statistics and state. what would you recommend for statistics that are only collected when something happens? stats that aren’t available on schedule. as an example, take UPS state changes to battery mode or overvoltage mode. Prometheus can’t collect them when they are short lived.
Depends
To me this is where SNMP traps shine, its quite specifically its purpose. Which means alloy, logstash, snmptrapd + promtail, logstashetc. Which fits best depends on what youre doing, I personally lean simple first. Do you want traps by themselves? Remote logs? Do you have a device thats already handling relays that can be triggered? How does the UPS connect? If its serial or USB over to a dedicated machine, that machine should log and send upstream.
