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.
