IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Garbage Collection Analysis workspace
This workspace summarizes all the Java Virtual Machine's garbage-collector activity over a user-defined interval. The JVM generates detailed garbage collection logs for an application server when started with the verbose:gc runtime parameter.
This workspace displays data provided by the Garbage Collection Analysis attributes.
The predefined workspace contains the following items:
- Garbage Collection Rate - History graph, which displays the rate at which the garbage-collection algorithm is being invoked
- Heap Usage - History bar chart
Displays the high water mark of free storage (in kilobytes) available in the heap after each garbage-collector run
- Percentage of Time Garbage Collector Running - History graph, which displays the percentage of real time the garbage collector was running during the current interval, for each server region
- Garbage Collection Analysis report, which displays information about the garbage-collection activities within the Java Virtual Machine that is hosting the application server. For example, this report displays the number of times the collector ran during the interval and the resulting number of objects that the collector freed
Access the Garbage Collection Analysis workspace
To access this workspace, perform the following steps:
- Within the Navigator, expand Windows Systems, Linux Systems, UNIX Systems, as appropriate for the node you are monitoring.
- Within the node list, expand the entry that corresponds to your node's name.
- Within that node's list of monitored applications, expand the list of J2EE agents.
- Within the list of available agents, expand the J2EE application server of your choice.
- Within that server's list of available J2EE application server workspaces, click the Garbage Collection Analysis entry.
