Runtime Performance Advisor uses PMI data to provide recommendations for performance tuning.
The Performance and Diagnostic Advisor uses Performance Monitoring Infrastructure (PMI) data to provide recommendations for performance tuning. Running in the JVM of the application server, this advisor periodically checks for inefficient settings, and issues recommendations as standard product warning messages.
The Performance and Diagnostic Advisor recommendations are displayed in two locations:
- The WAS SystemOut.log log file.
- The Runtime Messages panel in the admin console.
Troubleshooting | Runtime Messages | Runtime Warning
