------------------------------------
Summary: Thread Usage Health Check
Key: SLING-6698
URL: https://issues.apache.org/jira/browse/SLING-6698
Project: Sling
Issue Type: New Feature
Components: Health Check
Reporter: Georg Henzler
Assignee: Georg Henzler
This health check should use java.lang.management.ThreadMXBean to provide the
following:
* A quick overview what an instance is doing via http (there are many other
means of monitoring, but there is nothing easier than using the the HC
servlet). This works well as all relevant tasks in sling (requests, jobs,
schedulers) set the thread name to a meaningful name
* It should WARN if all threads are highly utilised (but never send CRITICAL as
a fully utilised instance is not necessarily a problem)
* It should use the deadlock detection of ThreadMXBean of send CRITICAL
