I’m looking into setting up some monitoring combined with simple automation for my selfhosting. Currently I was thinking about using Zabbix.
I want to:
Track bandwidth usage on a router/fw and on a managed switch and track cpu/ram/disk usage on my vms.
Simple monitoring (up/down/maintenance) on the router, switch, my vms as well as on linux services (jellyfin/forgejo/etc) and windows services (lab for studying work-related tools).
I’m also interested in doing simple https checks on my webuis (i’ve had a service running but the website returning both 403 and 404 before) and testing nslookup on my internal dns (if the service is up but the lookups timeout I still want to try restarting the service).
Is there any FOSS/FLOSS alternatives that I should look into before diving into Zabbix?
But these 3 are all about metrics, right? While they’re great to monitor and analyse numbers (ping times, disk space, memory, etc.), they aren’t that great with e.g. plaintext error messages in log files. That’s how I remember it from a few years ago, at least.
Grafana/Loki does logs. Still early days for me but it’s solid so far.
