6 lockstat - DTrace kernel lock instrumentation provider
7
9 The lockstat driver is a DTrace dynamic tracing provider that performs
10 dynamic instrumentation for locking primitives in the Solaris kernel.
11
12
13 The lockstat provider makes probes available that you can use to dis‐
14 cern lock contention statistics, or to understand virtually any aspect
15 of locking behavior inside the operating system kernel. The lock‐
16 stat(1M) command is implemented as a DTrace consumer that uses the
17 lockstat provider to gather raw data.

20 The lockstat driver is not a public interface and you access the
21 instrumentation offered by this provider through DTrace. Refer to the
22 Solaris Dynamic Tracing Guide for a description of the public docu‐
23 mented interfaces available for the DTrace facility and the probes
24 offered by the lockstat provider.
