Why can't I see Linux disks through SNMP



Your Vote:



I am trying to convert from Solarwinds NPM to PRTG. I have snmpd configured on my RHEL AS3 boxes. When I try to add the "SNMP Linux Disk Free" sensor to my host I don't see anything available to monitor. In Solarwinds I can monitor / , /boot , etc.... I assume that it is using the Host Resources MIB. When I import that mib into PRTG as a library I can see hrStorageUsed etc... but I don't want to have to do a sensor factory sensor for every disk on every linux server. Is there something I am missing?

In order to monitor SNMP-based Disk Space sensors you require entries similar to the one listed below in the /etc/snmp/snmpd.conf file:

# PATH:  mount path to the disk in question.
# MIN:  Disks with space below this value will have the Mib's errorFlag set.
#        Default value = DEFDISKMINIMUMSPACE.

# Check the / partition and make sure it contains at least 10 megs.

disk / 10000

Extracted from the snmpd.conf:

Disk Usage Monitoring:

This requires that the agent was built with support for the ucd-snmp/disk module (which is included as part of the default build configuration).

disk PATH [ MINSPACE | MINPERCENT% ] monitors the disk mounted at PATH for available disk space.
