It may seem like running debugger on an application, but it most certainly is not. Debuggers intercept all the application's instructions introducing huge delays. DTrace on the other hand is built deeply into Solaris kernel, firing off its code only when instructed to trace some particular event, which is done by DTrace probes. By default all the probes are disabled. When DTrace code like above is executed, Solaris kernel substitutes small piece of its own assembly code with instructions informing DTrace framework about particular event. This code is only executed when traced event happens. This behavior results in literally no overhead when tracing rare events like sending signals to applications and very small overhead when tracing larger number of very often occurring events.

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 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. ATTRIBUTES
