EJB subsystem thread-pool statistics largest-thread-count is counting threads instead of show the peak of parallel use ---------------------------------------------------------------------------------------------------------------------- Key: WFLY-8966 URL: https://issues.jboss.org/browse/WFLY-8966 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 11.0.0.CR1 Reporter: Wolf-Dieter Fink Attachments: ejb31-timer.jar The description of "largest-thread-count" is => "The largest number of threads that have ever simultaneously been in the pool." But the behaviour at runtime shows that it is handled similar to task-count. If only one thread is used it will increased for every invocation until max-threads. As result the largest-thread-count is == max-threads after a short time. The helpful metrict to check whether the threads are exhaused is missing!
