Ruby GC Instrumentation

The RPM Ruby Agent now includes Garbage Collection statistics for applications running Ruby Enterprise Edition as well as Ruby versions with the Railsbench GC patches compiled in. This detailed information includes:
- Details on the time spent in GC for each controller action
- Number of GC calls made on average for each controller action
- A new segment in the breakdown graph showing the amount of time spent overall in Garbage Collection
To activate the feature, add the following call in your application initialization:
GC.enable_stats
