Joe,
Are you refering to Jetty's raw jmx statistics available from the
management console or to Jetty's JSR77 implementation?
Jetty supports JSR77 via a filter. Have a look at the Jetty extra/jsr77
package in the Jetty source tree. It is part of the JettyPlus server, but
should be able to be extracted to work with vanilla jetty. I've attached
the jettyplus config files that enables it for your info.
I can work with you on this to enable jsr77 for jetty if you'd like.
cheers

I'm working a new JSR77 like management API for performance monitoring
of Jetty (soon to be followed by Tomcat) started by Aaron. However,
I'm hitting some incompatibilities between the currently available Jetty
statistics from the server (and displayed in the console today) and
JSR77 performance monitoring style reporting.
Jetty can report averages for some attributes such as the number of
connection requests, the duration of connections and the duration of
requests. When Jetty provides an average of some statistic the only
other value typically provided is the maximum (this is true for all three).
JSR77 performance monitoring does not track/store any averages. Rather,
for TimeStatistics only, it is expected that the average can be computed
by dividing the total time by the total count. There is not a way to
compute the average for range statistics (such as the connection
requests). I would like to be able to infer the missing values from
the average but I don't have enough information available from Jetty.
Given this mismatch I can do one of the following:
1) Don't make available the reporting of averages from Jetty for the
three statistics. Since there are no other values available, the result
will be that we will only display the maximum value for the particular
statistic(for Time values we'd be missing minimum, total time, and count
- for Range that's current and LowWaterMark).
2) Provide some extensions on the JSR77 Statistics in the console or
geronimo Jetty packages to store and retrieve the averages in addition
to the other values. Once again we would not have values for the other
statistic fields ... just average and maximum.
I'll need to work out the same or similar performance statistics for
Tomcat as soon as I have the Jetty capability resolved (which I hope is
still in the next day). So, I'll need some help from you Tomcat experts
soon! :-)
