On the MDS you can easily gather mdt journal stats by a read to /proc/fs/jb2/<mtd dev id>/info. This file is read only so it is impossible to clear the values to make data analysis easier.

Closing ticket per James Simmons recent comment:
This is more of a upstream kernel patch that is not related to lustre.

This is a change that we might consider for a future 2.x release but would not include for 2.1
