I think so, but it's been a while since I've dug into it.

You need to change line 9 of the mrtg script, and include the debug
targets you are interested in:

# cfg  - watch the config file reading
# dir  - directory mangeling
# base - basic program flow
# tarp - target parser
# snpo - snmp polling
# snpo2 - more snmp debug
# coca - confcache operations
# repo - track confcache repopulation
# fork - forking view
# time - some timing info
# log  - logging of data via rateup or rrdtool
# eval - trace eval experssions
# prof - add timeing info some interesting bits of code

I'd try snpo and snpo2 to start off.  A lot of that gets written into
confcache, so add coca if the first two don't help.
