IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

JVM thread display

Use the JVM thread display page to view all threads running within the JVM of an application server.

To view the JVM thread display page, from the top navigation click

You can also access this page from the toolbox icon on the Server Activity Display page.

Select the server group name in the Group list box, and the server name in the Server list box. If you access this page from the Tivoli Enterprise Portal and from the Server Activity Display page, the server group name and server name display automatically.

At the top of the page, the snapshot date and time and the server name and IP address are displayed. The timestamp for Snapshot Date and Snapshot Time is collected from the data collector and converted to the time zone of the managing server.

The page initially displays a list of top-level thread groups and active threads.

To view thread groups and active threads within a thread group, click the name of the thread group. A Thread Group Properties pane displays on the right of the page, showing information for the current thread group.

To view information for a thread, click its name. A Thread properties pane displays on the right of the page, showing information for the thread.

To change priority for the thread, in the Thread properties pane select the new priority in the Priority list box and click the Change Priority button.

The new priority remains for the life of the thread. As a result, any requests assigned to that thread after the change hold that priority.

To view a stack trace for the thread, in the Thread properties pane click the View Stack Trace button.

Cancelling a thread might cause JVM and application server instability. Use the cancel thread function only when absolutely necessary, and with careful consideration of the consequences.

To cancel the thread, in the Thread properties pane click the Cancel Thread button.

To troubleshoot a multithreaded application, you might need to view the thread dump, which includes detailed information about memory allocation of all threads in the JVM. To view the thread dump, click the Thread Dump button, located in Server Properties at the top of the page.
