These attributes belong to the attribute group "Application Server":

Hung Threads Total: Total number of detected hung threads. The valid format is a positive integer.
Hung Threads Blocked: Number of hung threads detected in the BLOCKED state. The valid format is a positive integer.
Hung Threads Waiting: Number of hung threads detected in the WAITING state. The valid format is a positive integer.
Hung Threads Timed Waiting: Number of hung threads detected in the TIMED_WAITING state. The valid format is a positive integer.

These attributes are used in the WebSphere App Server workspace, Application Server Summary view.

There are no corresponding PMI counters for them, hence the question.

That data comes from the ThreadMXBean directly

The monitored threads are defined in itcamdc/etc/toolkit_config_kwj.xml
