Thanks for sharing your home lab setup, I have settled on using Nagios for monitoring my servers, I like that I can put a lightweight agent on each node and have it run my custom checks and then report back to the central nagios dashboard. The dashboard handles notifications and tracking history graphs ect.
I do like the idea of having an uptime kuma instance running in docker as a second monitor, I will take a look at fly.io thanks for the suggestion.
Looking forward to more posts about your home lab. Are you using pfsence for your router/firewall?
I use CheckMK (fork of Nagios) for monitoring machine metrics, but I use Uptime Kuma for alerting.
I use OPNSense for my firewall.
Now I am interested in seeing your thoughts and configuration for checkMK and OPNSence.
Have you already posted on these subjects?
No, but I was planning on posting on different systems over time, I just don't post a lot these days. The only other one I have posted on so far is NextDNS.
