Hi all,
I’m new in the CheckMK community as I’m changing the monitoring in my homelab from Zabbix (which I’ve used for the last 5 years) to CheckMK. After I’ve had an initial look at CheckMK I find it much more easy to use for me 
After reading and learning a lot in the last days, I’m struggling with the LVM monitoring of my Proxmox hosts.
I’ve installed the LVM plugin to the agent of my Proxmox hosts and the plugin returns correct data:
root@pmx1:~# /usr/lib/check_mk_agent/plugins/lvm.txt

On this host the Proxmox lvm-thin storages which I want to monitor are:
- data/pve (This is what Proxmox creates by default on /dev/sda, named “local-lvm” in Proxmox
- local-lvm1 (Additional datastore)
- local-lvm2 (Additional datastore)
- local-lvm3 (Additional datastore)
But when I run the discovery in CheckMK, I’m getting only three LVM pools:
The output from the agent lists 10 pools, why do I only get 3 in CheckMK? Especially I absolutely need the “data/pve” pool as this is a used LVM pool which I need to monitor.
Any idea is highly appreciated.
