IBM Tivoli Composite Application Agent for J2EE, Version 7.1.1

Setting the Heap Dump scan interval and logging

The Heap Dump Management function of ITCAM for J2EE can create Heap Dumps of the monitored IBM® WebSphere® Application Server by user request.

Once in a defined time interval, ITCAM for J2EE scans the existing Heap Dumps, to inform the user of their existence. This scan also serves to delete heap dump files that are over 48 hours old.

By default, this interval is every 12 hours. To change the interval, set the following property in the custom_directory/toolkit_custom.properties file to the new interval in seconds:

am.mddmgr.poll.delay

To enable logging of heap Dump scans, set the following property in the cynlogging.properties file. This file is located in the directory that also contains custom_directory:

CYN.trc.datacollector.level=DEBUG_MIN

Once every scan interval (12 hours by default), Heap Dump scan messages are logged in to the trace-dc-ParentLast.log file.
