It will be different for pretty much every chassis, maybe every boot.

I use the following snippet in my template to query the entity sensor mib,
examine the thresholds and sensors, and create useful configs.  This one is
particular to dB loss on optics, but you should be able to change the "next
if $ttype..." line more to your liking and set the units elsewhere more
appropriately.

# Look for dBm meters - probably interesting
