lockstat(7D) Devices lockstat(7D)NAMElockstat - DTrace kernel lock instrumentation providerDESCRIPTIONThe lockstat driver is a DTrace dynamic tracing provider that performs dynamic instrumentation for locking primitives in the Solaris ker- nel. 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(1M) 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 Solaris Dynamic Tracing Guide for a description of the public documented interfaces available for the DTrace facility and the probes offered by the lockstat provider.ATTRIBUTESSee attributes(5) for a description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWdtrp | +-----------------------------+-----------------------------+ |Interface Stability |Private | +-----------------------------+-----------------------------+SEE ALSOdtrace(1M), lockstat(1M), attributes(5), dtrace(7D) Solaris Dynamic Tracing Guide SunOS 5.11 3 Sep 2003 lockstat(7D)
