Concurrent requests being sent to the tomcat dont match with Dynatrace JVM threads

We are running performance test and using DynaTrace to monitor the run. While performance team claims to be sending concurrent requests to the tune of 900 at one point of time. I don't see that being reflected on the DynaTrace JVM threads .Is this the right place to check this ON DT or there is something wrong in the test itself. Also Jmeter shows all the requests to be successfull. Any pointers will be helpful

Hi,

This depends on the settings of the maxThreads in Tomcat. So when maxed to 600 you can also serve 900 concurrent requests, but some have to wait till a worker thread is available. See also the doc https://tomcat.apache.org/tomcat-9.0-doc/config/executor.html
