+1 for CMK. It’s built on nagios. Been using it for decades. That shit is rock solid and has never let me down.
Prometheus is metrics and grafana reports it. IMHO, better reporting and graphing, better eye candy. But also harder to setup and get right.
CMK agent works on 95% of what you want with just the agent.
I use it on reclaimed hardware … Works great for me. Has all the features you’d want for a home lab, and I run a few production hosts there as well
I have a rack in my garage.
My advice, keep it simple, keep it virtual.
I dumpster dove for hardware and run proxmox on hosts. Not even clustered, just simple stand alone proxmox hosts. Connect to my Synology storage device and done.
I run next cloud for webDav contacts and calendar (fuck Google), it does photo and do. Storage. The next client is free from F-Droid for Android and works on debian desktops like a charm.
I run Minecraft server
I run home automation server
I run a media server.
Proxmox backs everything up on schedule
All I need to do is get off-site backup setup for Synology important data and I’m all set.
It’s really not as hard as you think if you keep it simple
Dont trust or use Google drive. Google wouldn’t offer that space for free…they get something out of it.
How many non tech people would use this, especially if not in play store. 95% of people don’t know fdroid exists
