Collecting and saving binary JVM trace data (Java applications only)
Some of the data that is collected by Health Center from Java™ applications comes from trace points in the monitored JVM. You can specify additional data to be collected, by adding extra trace points. You can export this data as a binary JVM trace file, which you can then transform into a readable format by using the Trace Formatter utility of your Java run time.
Before you begin
About this task
You can export data that is collected from trace points, such as Garbage Collection data, Profiling data, and Classes data, to a binary JVM trace file. You can also specify other trace points to use when collecting data. This extra data is only collected; it is not used in the generation of graphs or time lines in Health Center. You can also temporarily disable trace points, or remove them altogether.
Note: Be careful when disabling or removing trace points; you might disable or remove trace points that Health Center uses to generate graphs and time lines.
Procedure
What to do next
You can change the trace file into a text format by using the Trace Formatter utility provided with the Java run time that runs the monitored application. For more information about trace formatting, see the topic about the trace formatter, in the documentation for your version of the IBM® SDK and Runtime Environment Java Technology Edition. For example,
Using the trace formatter.

Note: When using the trace formatter on an exported trace file, errors might be reported. The errors are because the Health Center agent has a finite buffer size. When the buffer is full, data must be dropped.
