In addition to the compiler configuration file, there is a separate configuration file for the utilization tracking and reporting feature. Utilization tracking is disabled by default, but you can enable it by modifying an entry in this configuration file. Various other aspects of utilization tracking can also be configured using this file.
Although the compiler configuration file is separate from the utilization tracking configuration file, it contains an entry that specifies the location of the utilization tracking configuration file so that the compiler can find this file.
For more information about how to configure the utilization tracking and reporting feature, see Tracking and reporting compiler usage in the XL C/C++ Compiler Reference.
