Advisor View

The Advisor view contains a set of suggestions for improving the performance of your application based on the data collected so far.

When displayed, the Advisor view is located, by default, to the right of the Projects view, overlaying the Collect and Analyze views.

To open the Advisor view, click on the Generate Advice button or toolbar choice. This will analyze the collected data and produce advice output.

The figure below shows the Advisor view:
