I have some hosts in a Template in zabbix for monitoring. All items are work correctly for all hosts except an item vfs.fs.size[/,used] just for one of them in zabbix web interface.
The host OS is Debian 7.3 and Zabbix agent version is 2.0.9.
Note: every time i try that key by zabbix_get
from the host, it work correctly and just in zabbix web interface nothing monitor.
