If the volume of messages is too high,
you might have luck with "domain"
logging, which narrows it to
particular functional realms, for
example:

setconf Log="[edge] debug file logfile001"

where the "edge" domain relates to event
processing.  See

   Log [domain,...]

in

   https://www.torproject.org/docs/tor-manual.html.en

for details and the full list of message domains.
