A mechanism is provided for collecting one or more performance metrics. A plurality of source code instructions is provided. The source code instructions include a plurality of macro calls. Each of the plurality of macro calls includes a plurality of predetermined parameters. A plurality of object code instructions corresponding to the plurality of source code instructions is executed. In response to receiving a signal identifying at least one of the plurality of macro calls contained in the source code instructions and identifying a desired level of granularity, performance metrics are collected using the identified macro call in accordance with the desired level of granularity.
