M/R Staticstics

When I submit a simple "Hello World" M/R job like WordCount it takes 
less than 5 seconds. The texts show numerous methods for monitoring M/R 
jobs as they are happening but I have yet to see any that show 
statistics about a job after it has completed. Obviously simple jobs 
that take a short amount of time don't allow time to fire up any web 
mage or monitoring tool to see how it progresses through the JobTracker 
and TaskTracker as well as which node it is processed on. Any 
suggestions on how could see this kind of data *after* a job has 
completed?

do you see "retired jobs" on job tracker page. There is also "job tracker
history" on the bottom of page.

something like this http://nn.zettabyte.com:50030/jobtracker.jsp

Thanks and Regards,
