The collector will call into the registry to gather contention metrics for all registered mutex objects. A new JS test will verify the behavior of the collector:
- It honors specified tracking modes for registered mutex objects.
- The aggregate metrics are monotonically increasing.
- The metrics for mutex objects that are separately reported are zeroed out after they are destroyed.
- The detailed report includes all registered mutex objects.
- The metrics are properly recorded by FTDC.
