History

George V. Neville-Neil 480f4e946d Add an mbuf provider to DTrace. The mbuf provider is made up of a set of Statically Defined Tracepoints which help us look into mbufs as they are allocated and freed. This can be used to inspect the buffers or for a simplified mbuf leak detector. New tracepoints are: mbuf:::m-init mbuf:::m-gethdr mbuf:::m-get mbuf:::m-getcl mbuf:::m-clget mbuf:::m-cljget mbuf:::m-cljset mbuf:::m-free mbuf:::m-freem There is also a translator for mbufs which gives some visibility into the structure, see mbuf.d for more details.

README

$FreeBSD$

This directory contains scripts for use with the DTrace system.  The
toolkit/ directory installs the latest vendor import of Brendan
Gregg's DTraceToolkit while the other files and directories
contain code generated by the FreeBSD Project for use with DTrace on
FreeBSD.

NOTE: Do not add new scripts to the toolkit directory. New DTraceToolkit
scripts should be send to the maintainer of the toolkit and then brought
back into FreeBSD via future vendor imports.
