I have a partition which contains the "." character. I would like to monitor the total disk space available for this device. The agent says this is possible on the command line, yet nothing get's returned to the server.

1. mount
   /dev/etherd/e0.0 on /mnt/e0.0 type ext3 (rw)

1. zabbix_agentd -t vfs.fs.size[/mnt/e0.0]
   vfs.fs.size[/mnt/e0.0] [u|6249399196]
2. zabbix_agentd -t vfs.fs.size[/mnt/e0.0,free]
   vfs.fs.size[/mnt/e0.0,free] [u|177327400]

The key matches the above keys, and is set to update on a 60 second interval. The UI does not show the item as unsupported or any other error yet nothing is ever displayed.
