There's a guy here from Sandia (Jim Brandt) talking about a tool
called 'Ovis'.  It's not exactly like darshan.  more like TACC stats.  

the statistics collection approach is different from darshan, but
there are probably some good ideas in their data exploration UI.

they use something called 'baler' log file analysis from Louisiana
Tech (Narate Taerat working under Chokchai 'box' Leangsukusn).  Looks
at a bunch of log files and groups similar things, but also will flag

there are other components of this project that aren't so relevant to
darshan, at least not until darshan decides to send stats to a central
location: a lightweight distributed metric service to collect stats
from every node.
