Choosing the right performance advisor for the purpose

Two performance advisors are available: the Runtime Performance Advisor and the performance advisor in Tivoli Performance Viewer (TPV advisor). The Runtime Performance Advisor runs in the Java virtual machine (JVM) process of Application Server; therefore, it does not provide expensive advice. In a Network Deployment environment, the performance advisor in TPV runs on the node agent and can provide advice on resources which are more expensive to monitor and analyze. The TPV advisor requires that you enable performance modules, counters, or both.

The following chart shows the differences between the Runtime Performance Advisor and the TPV advisor:
  Runtime Performance Advisor TPV advisor
Start location Application server TPV client
Invocation of tool TPV Administrative console
Output The SystemOut.log file and the administrative console TPV in the administrative console
Frequency of operation Configurable When you select refresh in the TPV administrative console
