Measures reported by WASThreadTest

To optimize performance and at the same time to support concurrent accesses from users, the application server uses thread pools. It is critical to monitor a WebSphere server's thread pools on an ongoing basis. This test monitors the thread pools on a WebSphere server.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Active_count The number of threads that are currently active Number A high value for this measure is indicative of a high load on this application and combined with the creation and destroy rates might give insights of the application pattern.
 
Create_count The number of threads that were created since the last measurement period Number A sudden increase in the value of this measure directly relates to an increase in the activity happening in this application.
Destroy_count The number of threads that were destroyed since the last measurement period Number A decrease in the value of this measure indicates that the threads are being active for a long period of time, which might indicate anomalies within the application.
Pool_size The number of threads in the pool, currently Number If the pool size is high and the number of active threads is low, it signifies that the threads are not being destroyed immediately after use.
Threads_hung_count The number of concurrently stopped threads Number
