WLST Thread Count

WLST Thread Count in WebLogic 9.x and all higher version the Thread model is depends on WorkManager. The WorkManager internally uses self-tuning threads for each WebLogic Server instances.
-->

To get the thread Model and its Idle count as in the WebLogic 8.1 we need to tune the server instance parameter in the config.xml. While changing this you should be cautious,

 make sure you have  a backup copy the config.xml before editing.
Enter the following line in the child element, given same level as element.






Full detail description about how to change this parameter is given here...

The WLST script for Thread count monitoring will be as follows:
