Viewing the Runtime Performance Advisor recommendations

Runtime Performance Advisor uses Performance Monitoring Infrastructure (PMI) data to provide recommendations for performance tuning.

About this task

The Runtime Performance Advisor uses Performance Monitoring Infrastructure (PMI) data to provide recommendations for performance tuning. Running in the Java virtual machine (JVM) of the application server, this advisor periodically checks for inefficient settings, and issues recommendations as standard product warning messages.

Procedure

The Runtime Performance Advisor recommendations are displayed in two locations:
  1. The WebSphere Application Server SystemOut.log log file.
  2. The Runtime Messages panel in the administrative console. To view this administrative page, click Troubleshooting > Runtime Messages > Runtime Warning.

Example

The following log file is a sample output of advice on the SystemOut.log file:
[4/2/04 15:50:26:406 EST] 6a83e321 TraceResponse W CWTUN0202W: 
Increasing the Web Container thread pool Maximum Size to 48 
might improve performance. 

Additional explanatory data follows.

Average number of threads: 48.

Configured maximum pool size: 2.

This alert has been issued 1 time(s) in a row. 
The threshold will be updated to reduce the 
overhead of the analysis.
