raw_data

Returns an Array of individual raw profile data Hashes ordered from earliest to latest by :GC_INVOKE_TIME.

For example:

[
  {
     :GC_TIME=>1.3000000000000858e-05,
     :GC_INVOKE_TIME=>0.010634999999999999,
     :HEAP_USE_SIZE=>289640,
     :HEAP_TOTAL_SIZE=>588960,
     :HEAP_TOTAL_OBJECTS=>14724,
     :GC_IS_MARKED=>false
  },
  # ...
]

The keys mean:

:GC_TIME

Time elapsed in seconds for this GC run

:GC_INVOKE_TIME

Time elapsed in seconds from startup to when the GC was invoked

:HEAP_USE_SIZE

Total bytes of heap used

:HEAP_TOTAL_SIZE

Total size of heap in bytes

:HEAP_TOTAL_OBJECTS

Total number of objects

:GC_IS_MARKED

Returns true if the GC is in mark phase

If ruby was built with GC_PROFILE_MORE_DETAIL, you will also have access to the following hash keys:

:GC_MARK_TIME

:GC_SWEEP_TIME

:ALLOCATE_INCREASE

:ALLOCATE_LIMIT

:HEAP_USE_SLOTS

:HEAP_LIVE_OBJECTS

:HEAP_FREE_OBJECTS

:HAVE_FINALIZE
