Not able to get threadcount and thread busy metrices in Tomcat 7.0
Hi ,
I am facing a problem. We used to monitor tomcat JVM and used to monitor
" current ThreadCount " and "current Threadbusy"
Recently we upgraded from tomcat 6.0 to tomcat 7.0.16 and we are not
able to get these metrices .
On digging in we found that in tomcat6.0 the thread pool metrices were
retrieved by class "org.apache.tomcat.util.threads.ThreadPool "
But in tomcat 7.0 there is no such class instead it is replace by
org.apache.tomcat.util.threads.ThreadPoolExecutor which does not give
the above parameters.
So my question is tomcat 7.0 how can we get the above metrices
P.S- > Am new to tomcat so please bear if it is a silly question
Regards
Shashank

What about these methods in the ThreadPoolExecutor's superclass:
getCorePoolSize
getActiveCount
Those appear to be exactly what you're looking for.
You could also use JMX if you were so inclined.
