SNMP Disk Free error display neg numbers

Votes:

0

I have 2 servers that are similar. They are HP DL 385. Each has an 11TB ext4 file system mounted under the /data directory. Currently there is 6+TB free on each system.

My problem is that the snmp disk free sensor reports 0% free space on both servers /data filesystem. In fact the minimum value column in the sensor reads with a negative number.

How do I troubleshoot this and fix??

Thanks --Kenny

Negative numbers? In that case, would you please forward a mail including screenshots of this, as well as the settings page of the sensor, and any potentially other descriptive screenshots, as well as a full support bundle to [email protected]?
