Why does Redhat disable support lm_sensors support in net-snmp? The spec file contains everything needed to add lm_sensors support but it is disabled by default.  I modified the spec file and rebuilt the RPM to enable lm_sensors on my CentOS boxes. Seems to work fine for me. I’d love to know why they disabled it though.

Here’s a great article on setting up cacti with lm_sensors:
