NAME

lockstat - DTrace kernel lock instrumentation provider

DESCRIPTION

The lockstat driver is a DTrace dynamic tracing provider that
performs dynamic instrumentation for locking primitives in the
kernel.


The lockstat provider makes probes available that you can use to
discern lock contention statistics, or to understand virtually any
aspect of locking behavior inside the operating system kernel. The
lockstat(8) command is implemented as a DTrace consumer that uses the
lockstat provider to gather raw data.


The lockstat driver is not a public interface and you access the
instrumentation offered by this provider through DTrace. Refer to the
Dynamic Tracing Guide for a description of the public documented
interfaces available for the DTrace facility and the probes offered
by the lockstat provider.
