| mtrace |
| |
| This agent library can be used to track method call and return counts. |
| It uses the same java_crw_demo library used by HPROF to do BCI on all or |
| selected classfiles loaded into the Virtual Machine. It will print out a |
| sorted list of the most heavily used classes (as determined by the number |
| of method calls into the class) and also include the call and return counts |
| for all methods that are called. |
| |
| You can use this agent library as follows: |
| |
| java -Xbootclasspath/a:mtrace.jar -agentlib:mtrace ... |
| |
| To get help on the available options try: |
| |
| java -agentlib:mtrace=help |
| |
| See ${JAVA_HOME}/demo/jvmti/index.html for help running and building agents. |
