The utilization tracking and reporting feature is a lightweight and simple mechanism for tracking the compiler utilization within your organization. It is disabled by default. You can use this feature to detect whether your organization's use of the compiler exceeds your compiler license entitlements.
When utilization tracking is enabled, each invocation of the compiler is recorded in a compiler utilization file. You can run the utilization reporting tool to generate a report from one or more of these files to get a picture of the overall usage of the compiler within your organization. The urt command can be used to control how the report is generated. In particular, the report indicates whether the compiler usage complies with the number of Concurrent User licenses that you have purchased.
The utilization tracking and reporting feature is easy to set up and manage, and utilization tracking does not impact the usage or performance of the compiler.
For detailed information about the utilization tracking and reporting feature, see Tracking and reporting compiler usage in the XL C/C++ Compiler Reference.
