Summary: 0002422: PortMXBean statistics
Description: (rep by Knut Forkalsrud)

I'm trying to get some statistics out of my Resin instance through the JMX beans.
Some of the interesting metrics on PortMXBean seem to be missing, notably the
following properties:

requestCountTotal
requestCountKeepalive
requestCountClientDisconnect
requestTimeTotal
requestBytesRead
requestBytesWritten

I've tried to trace the source code for where they're updated, but I can't find any
code that does that. The attached jsp page illustrates the issue. As I load the
page over and over the metrics do not change, they're always zero. I've run this
on 3.1.4 and 3.0.23, and they're both the same in this respect. Is there a trick
I need to invoke to get this going, or is it simply not implemented?

Thanks
