I have just setup a fresh CheckMK server and am monitoring 13 servers in a Proxmox VE cluster. No errors, all is great.
After following the great article by Alexander Wilms Proxmox Monitoring: How to Do it Efficiently with Checkmk I am simply STUCK on this line:
Aside from the agent, configure and use the Proxmox VE special agent in Checkmk.
I just have no idea what that means. I can go to Settings->Agents->VM, Cloud, Container->Proxmox VE but once there I see nothing that I can even do. Just a blank set of rules.
So the question is pretty embarrassing: HOW do I install(?) or activate(?) the Proxmox VE Special Agent? Is it something I install on the Proxmox server? Worse: What is a “Special Agent”?
