COH Add Thread status log entries to Liberty code - Equivalent of TWas Runtime.ThreadMonitorHeartbeat

Traditional WebSphere had a configuration setting (Runtime.ThreadMonitorHeartbeat) that instructed it to log details about its thread pool usage e.g. the number of hung threads/size of the pool.

Liberty does not have this functionality.

Liberty only has one thread pool but it would still very useful to be able to see the history of the state of the threads.
This needs to be logged for support staff who are analysing the logs after an event to understand at what point the problem occurs.

These are the instructions for configuring this functionality for the traditional WebSphere system.

## Configuring the Websphere Thread Pool statistics to log key thread counts and their status ##
# Servers > Application Servers > Server Name > Troubleshooting > Logging and Tracing > Configuration > General Properties > Log Level Detail
:Runtime.ThreadMonitorHeartbeat=detail

 

Use case:
Who would use this?
support staff who need to:
Identify the state of the thread pool e.g. how many threads were hung at a particular moment in time

How frequently would it be used?
it would be used when investigating the health of a jvm and after a serious issue
