NAME

6       lockstat - DTrace kernel lock instrumentation provider
7

DESCRIPTION

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.
18
19
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.
