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?
