It is possible to create graphs of the Proxmox VMs that run on your monitored machines. Currently, only traffic graphs are created. One for each interface on each VM. Possibly, IO graphs will be added later on.
The ultimate goal is to be able to create traffic bills for VMs, no matter on which physical machine that VM runs.
Enabling Proxmox graphs
To enable Proxmox graphs, do the following:
In config.php, enable Proxmox:
$config['enable_proxmox'] = 1;
Then, install librenms-agent on the machines running Proxmox and enable the Proxmox-script using:
cp /opt/librenms-agent/agent-local/proxmox /usr/lib/check_mk_agent/local/proxmox chmod +x /usr/lib/check_mk_agent/local/proxmox
Then, restart the xinetd service
Then in LibreNMS active the librenms-agent and proxmox application flag for the device you are monitoring. You should now see an application in LibreNMS, as well as a new menu-item in the topmenu, allowing you to choose which cluster you want to look at.
