-------------------------------------------
Here is an example job which has been set up for period-based thread pool monitoring
(threadpools monitored every 10 seconds):
You can view the thread pool statistics in one of two ways:
- view them in context as part of the server log output (e.g.
)
- view them as a file of statistics per server (e.g.
Create tool to monitor clustering thread pool usage

Key: WFLY-6321

https://issues.jboss.org/browse/WFLY-6321
Project: WildFly
Issue Type: Task
Components: Clustering
Reporter: Richard Achmatowicz
Assignee: Richard Achmatowicz
Priority: Minor
Scheduled executors and thread pools are used widely in JGroups and Infinispan for
asynchronously executing tasks. When thread pools are not adequately sized to the load
they are subjected to, this can lead to performance problems.
It would be helpful if we could see thread pool usage as a function of elapse time during
performance runs, in order to diagnose potential thread pool issues.
This task will provide a Byteman-based tool to monitor threadpool usage and allow a
report to be attached to SmartFrog test jobs.
