Overview of the DTrace Recorder

The DTrace Recorder is a tool for recording and visualizing DTrace data from a number of Operating Systems and HotSpot JVM probes.

Recordings can be created on both local and remote hosts.

Recordings contain information about which systems functions have been called, scheduling of threads on CPUs, Garbage Collections in the JVM, etc.

Note: It is very hard to estimate the performance overhead of DTrace. It should be approximately 10% with the included script, but your mileage may vary. Also changing the probes will alter the overhead.
