That would be great if you could send us a log file example.  I just 
tried a quick test on an old log file and it looked Ok in that 
particular case.  It might depend on the contents of the log.

We could probably add a command line option to produce that behavior.  
In the mean time you can at least use the --output option to specify the 
file name.

We don't have any great portable tools for looking at logs in aggregate 
yet.  There is one simple tool in test/darshan-gather-stats.pl (look at 
the comments at the top of the file for documentation) that can chug 
through a directory of darshan data and produce a text file with the 
amount of data and estimated performance for each job.  You could run 
that and then at least sort your jobs by performance or data usage or 
some intersection of the two.

Kevin and others have been working on a web-based dashboard that produce 
several different views of darshan data, but I think it is probably kind 
of tied to our site-specific tools?
