rb_objcpu.d - measure Ruby object creation on-CPU time using DTrace. rb_objcpu.d This traces Ruby activity from all programs running on the system with Ruby provider support. Class names are printed if available. Any Evolving - uses the DTrace Ruby provider, which may change as additional features are introduced. Check Ruby/Readme to see what version these scripts are based on.

Default output, # rb_objcpu.d

See the DTraceToolkit for further documentation under the Examples, Notes and Docs directories. The example files may be especially useful as they aim to demonstrate how to interpret the output. rb_objcpu.d will run until Ctrl-C is hit. Brendan Gregg [CA, USA] dtrace(1M)
