Enabling the Java Virtual Machine Profiler Interface data

Why and when to perform this task

The Java Virtual Machine Profiler Interface (JVMPI) enables the collection of information, such as data about garbage collection, object utilization, and thread states, from the Java Virtual Machine (JVM) that runs the application server and enables more comprehensive performance analysis. Once JVMPI is enabled, selected statistics can be enabled to collect specific data using the PMI custom option.

To enable Java Virtual Machine Profiler Interface (JVMPI) data reporting for each individual application server:

Steps for this task

  1. Open the administrative console.
  2. Click Servers > Application Servers in the console navigation tree.
  3. Click the application server for the JVMPI that needs to be enabled.
  4. Click Java and Process Management under Server Infrastructure.
  5. Click Process Definition.
  6. Click Java Virtual Machine under Additional properties.
  7. Type -XrunpmiJvmpiProfiler in the Generic JVM arguments field.
  8. Click Apply or OK.
  9. Click Save.
  10. Click Servers > Application Servers in the console navigation tree.
  11. Click the application server for the JVMPI that needs to be enabled.
  12. Click the Configuration tab. When in the Configuration tab, settings apply when the server is restarted. When in the Runtime Tab, settings apply immediately. Note that Performance Monitoring Infrastructure (PMI) can only be enabled in the Configuration tab.
  13. Click Performance Monitoring Infrastructure under Performance.
  14. Select the Enable Performance Monitoring Infrastructure (PMI) check box.
  15. Click Custom and select JVM Runtime on the left side tree.
  16. Click a JVMPI group under JVM Runtime and enable or disable the statistic on the right side table. Go back to the main PMI configuration page by clicking the Performance Monitoring Infrastructure link.
  17. Click Apply or OK.
  18. Click Save.
  19. Start the application server, or restart the application server if it is currently running.
  20. Refresh the Tivoli Performance Viewer if you are using it. The changes you make will not take affect until you restart the application server.
