NO DATA for disk space

[elzerox]

Hi, I have a zabbix server monitoring 21 servers

18 servers write well disk space graphics except 3 servers (one of them, the zabbix server itself). These 3 servers are OpenVZ containers (proxmox) Centos 6.6 32bit, the rest of servers are dedicated servers.

This is the error and some test that I've done (from zabbix server itself) after reading other posts

Please, can anyone help me? Thanks a lot!

dunno, if you need help anymore but simfs is not discovered by standard linux template, you can check 'File systems for discovery' regex in administration -> general -> regular expressions. This regex is used in discovery to filter discovered filesystems, you simfs root partition is just ignored, so it would probably work, if you add it to regexp.
