 Anita,
 
 Why extend from CountStatistic instead of
 TimeStatistic?  Can't we use 
 StartTime (from Statistic - parent of TimeStatistic)
 for the StartupTime 
 AIUI, StartTime in Statistic is to keep the time
when the statistics gathering started. It can be used
to compute other information for a given sampling
interval. The startupTime is slightly different. It is
the time taken to start the context (webapp).  
 and TotalTime for the ProcessingTime?  
I could use TotalTime of TimeStatistics for this.
I do not like filling all the other attributes (max,
min, count) to undefined values (-1 ?). I would prefer
the Count, its Unit can be used to format it correctly
in UI. 
That would
 just leave TldScanTime 
   in the extension class.  What is TldScanTime use
 for?
TldScanTime is the time to Scan the TLD contents
of all tag library descriptor files (including those
that are inside the jars 'accessible' to this webapp)
and register any application event listeners found
there. StartupTime is made up of tldScanTime, time to
load all servlets etc. May be tomcat users can comment
if is useful for performance tuning?  
  It brings me to another type of statistics say
'availability' which has a boolean value. Monitoring
tools constantly sample this value, and come up with
availability graphs and sometime take corrective
action. How do we represent this? Tomcat does provide
'availability' stats for an app. 

Thanks
Anita
