So besides filtering I am not sure how will pmacct tracks the statistic for the sessions. One more thing, I was running the debug mode and after a few hours it hangs my system and i could not even log into console, i had to power off and restart my box, which has 1Intel(R) Xeon E5420 2.50G and 16G memory, now after I turned of the debugging mode, the mysql process keeps consuming about 95% of cpu time.
