Checkmk is an IT monitoring software that tracks the health and performance of your systems, networks, servers, applications, and cloud services. It provides real-time insights, alerts for issues, and tools for troubleshooting, helping ensure smooth operations across your infrastructure.
To create a new Proxmox VE Checkmk LXC, run the command below in the Proxmox VE Shell.
To Update Checkmk, run the command below (or type update) in the LXC Console.
Screenshot looks interesting. Offcial website looks interesting as well.
However, when following the instructions, there appears no ‘checkmk.creds’ file is being generated.
Located the file with this command: find /opt/omd/sites -name “checkmk.creds” 2>/dev/nul
To find the user/pass needed, I used: cat /root/checkmk.creds
Perhaps add this to the instructions, as ‘cat ~/checkmk.creds’ showed nothing.
Yes, used Debian 12 and yes, used the Proxmox shell too (v8.3.1 if that is a concern or not).
I did use the ‘Advanced’ option during setup wizard of the LXC container, for the sole purpose of entering a pre-configured MAC address, as I use DHCP mapping extensively in my OPNSense router.
This also makes it easier to access the LXC container via SSH later on. As I didn’t get the info from the Proxmox shell, I used SSH access to find the creds file. And that worked like a charm.
