OPE Retriever

The Retriever collects information on persistent data handling and application-specific data. With control data that you specify as environment variables you can control tracing of your application. This chapter gives you the definition of the environment variables and a description.

This chapter also covers the Retriever application programming interface (Retriever API).

The Retriever API is a set of C++ classes that you can use to control tracing of your application. With this interface you can

• dd more application-specific information to the application trace.
• ontrol the amount of measured data.
• Limit tracing of the application to those parts you are interested in.
• Create several application traces within a single application run.
