Every announcement you see or hear on a Swiss train depends on a device someone needs to monitor.

At SBB, that's 50,000+ devices on about 800 trains.

NetworkChuck put Checkmk to the test in his homelab, uncovered hidden issues, and put AI agents to work alongside it for automated setup and recovery.

Big thanks for the collaboration, @NetworkChuck! 🙌

This is how I'm monitoring my Hermes agents:

- Set up @checkmk
- Configure a custom script to monitor:
- AI model subscription (OAuth)
- Cron jobs
- Memory health
- ...and whatever else I can think of.

I show how to do this in my latest video. (link in reply)

Setting up monitoring software for your homelab (and business) is a huge pain. That's why I usually don't do it...or I start and never finish it.

I started using @checkmk a few weeks ago, the free, open-source software that can monitor literally everything....and I think this one is going to be a different story for me. Why?

Because I can connect any of my AI agents to it to manage the monitoring for me. I set up a few things myself to see how things work and what it can monitor. Then...I just gave my AI agent the keys and it added ALL of my stuff, all of my infra, Docker containers, Proxmox VMs. It set up alerts and graphs and dashboards.

I'm hooked.
