1、The load-generating vm has 2 cores. 2、Can I use currentThreadsBusy to monitor the performance of Tomcat using APR connector? 2017-03-10 0:42 GMT+08:00 Christopher Schultz : > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA256 > > Linbo, > > On 3/8/17 8:13 PM,

Re: JMX currentThreadsBusy less than connections/requests when use APR connector

Hi, Here is the Connector configuration: I use wrk, the currentThreadsBusy is higher than the value in ab testing, but most of time is less than 40. ./wrk -t100 -c 100 -d 10s http://10.211.55.4:8080/ For APR connector, will it get one thread from the poll to deal with each request?

Re: JMX currentThreadsBusy less than connections/requests when use APR connector

Linbo, "currentThreadsBusy" is number of busy threads. These are the threads are being actively use. If you are seeing this count > 0 for long time(depending on your application type), then most likely you have "hung thread". In that case thread dump analysis will show you root of the problem.
