There are log parsers available that will tell you this information, but why not get it right from the source? How about general melee stats.

DPS average over the last 15mins.

DPS average of the last fight.

Damage taken average over the last 15mins.
Hit/Miss(dodge, riposte, parry) average over the last 15mins.

Stuff like that. It seems like a perfect fit for SEQ.
