This automatically collects a bunch of Ruby's GC-related metrics that
will come in handy while we tune the Unicorn workers. Some of theres
are:
* runtime.ruby.class_count
* runtime.ruby.gc.malloc_increase_bytes
* runtime.ruby.gc.total_allocated_objects
* runtime.ruby.gc.total_freed_objects
* runtime.ruby.gc.heap_marked_slots
* runtime.ruby.gc.heap_available_slots
* runtime.ruby.gc.heap_free_slots
* runtime.ruby.thread_count
Check https://docs.datadoghq.com/tracing/runtime_metrics/ruby/#data-collected for the complete list.
The cool thing is that
> Runtime metrics can be viewed in correlation with your Ruby services
