Hi,

 derp :)

Seems as my mistake.
Please make and attach debug for poller:

./poller.php -r -d m <hostname>

Hi,

Between r9885 -> r9886 there was a change (possibly lmsensors.inc.php ?) which seems to have caused any of our temperature sensors to drop to zero degrees.

Interestingly, where a host supports it, the output from SNMP / LM-SENSORS-MIB-lmTempSensorsValue still works, but the 'agent' retrieval from lmsensors consistently fails.

The issue persists up to r9890, any ideas please?

Cheers!
