I am trying to add an IMS4000 to my instance. This device has an available MIB, and I have managed to discover it correctly after adding an appropriate yaml file. However, it has some oddly-laid-out sensors I have been unable to add. The sensors are in two nested, parallel structures, as follows (from snmpwalk):
Values are in 1.3.6.1.4.1.8338.1.1.1.(1…17).8.1.1.7.(1…11)
Sensor types/units are in 1.3.6.1.4.1.8338.1.1.1.(1…17).8.1.1.3.(1…11)
Human names for sensors are in 1.3.6.1.4.1.8338.1.1.1.(1…17).8.1.1.2.(1…11)
I did find an existing PHP file, precache/avtech.inc.php, which uses regexes to solve a similar problem, but I’m not sure exactly how to use the precache mechanism to pick up these sensors – if anyone could point me to documentation for the meaning of the precache variables and how they’re interpreted into sensor entries, I’d appreciate it.
