The DTrace Toolkit
A set of scripts for use with DTrace on various systems.
The DTrace Toolkit was originally developed by Brendan Gregg and licensed under the CDDL. Various people have continued to work on the scripts in OpenSolaris and its derivatives, FreeBSD and Mac OS X.
Work continues on the toolkit with new scripts being licensed under the BSD 2-Clause license and modifications to the original scripts remaining under the CDDL. Do NOT change the license on existing files.
The master branch maintains the original imported scripts and is not to be modified. Each Operating System has its own branch (illumos, freebsd, macos) on which OS specific changes are to be maintained.
