Tomcat Executor MBean
Hi,
I am using an embedded version of Tomcat 7.0.42. Using java executor with
either of the connectors i.e. BIO/NIO.
However while monitoring the server via JMX, I see the mbean attributes,
currentThreadCount
currentThreadsBusy
always showing the value "-1".
The only one that shows the appropriate dynamic value is connection count,
which seems to match the count of the client threads that I initiate.
Any idea how to get currentThreadCount and currentThreadsBusy to show the
right values?
Thanks

All i am doing is creating an instance of a connector and setting it with
an java executor with an custom thread pool. Not sure i get it, when you
say registering the executor mbean, thought if connector is just
programmatically created, it shouldn't have really mattered. Moreover, it
does show the connection count accurately.
Do you have any pointers/references about registering of the mbean thing.

Are you registering the executor MBean with the JMX server? Tomcat will
auto-register the <Executors> in server.xml when running non-embedded,
but I'm not sure it will auto-register them if you programmatically add
Executors in an embedded environment.
