sdt - DTrace statically defined tracing provider
DESCRIPTION
The sdt driver is a DTrace dynamic tracing provider that performs dynamic instrumentation at statically-defined locations in the Solaris
kernel.
The sdt provider allows kernel developers to explicitly create probes at formally designated locations in the operating system kernel and
loadable modules, allowing the implementor to consciously choose the points in their code that are desired probe points, and to convey some
semantic knowledge about that point with the choice of probe name and a relevant set of arguments.
The sdt driver is not a public interface and you access 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
sdt provider.

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.

Hi,
I am trying to process line by line of a file. But I should not be allocating static allocation for reading the contents of the file. The memory should be dynamically allocated. The confusion here is how do I determine the size of each line, put it into a buffer with the memory allocated... (11 Replies)
Hi , I am new to this forum. Can someone help me on this question, I have no clue how to proceed . Its urgent..
A continuous program should print out the following dynamic information
(average of an interval). Internally, there should be two parameters with
your program, one is the probing... (5 Replies)
Hi,
I have a var sdt='23032011000000'
now if i want only 23 out of above? hw to cut?
also..after cuttint-will it be stored in another var as a varchar or as a number? (4 Replies)
