It looked interesting so I turned on

EntryStatistics 1 ConnDirectionStatistics 1 HiddenServiceStatistics 1

in addition to the default

DirReqStatistics 1

and the output is indeed interesting. Also have

CellStatistics 1

though this information does not seem to be published in the ExtraInfo digest.

Any reason why having any of these enabled might be a bad idea? Running 0.2.6.9.
