dtrace - DTrace dynamic tracing facility
DESCRIPTION
The dtrace driver provides the dynamic instrumentation and tracing facilities for the DTrace software, as well as the built-in dtrace
provider. The dtrace driver is not a public interface and you access the instrumentation offered by this provider through DTrace tools such
as dtrace(1M). Refer to the Solaris Dynamic Tracing Guide for a description of the public documented interfaces available for the DTrace
facility and dtrace provider probes.

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.

I'm looking for a good Solaris performance monitoring book. I work primarily with Solaris 9, but will also be working with 10, so a dtrace chapter would also be good. Any insight would be much appreciated. (4 Replies)
Hi
when I do dtrace -l | awk '{print $2}' I get a list of providers. Some of them are similar providers. I want to receive only once the same provide name.
Is there a way to do it?

Solaris 10. Getting a boatload of "Resource unavailable" on read errors for a Java process which is taking 350% of CPU. No I/O issues and dtrace shows lots of lwp calls. There are only 54 threads (or so, it fluxuates) but certainly not a lot. App is WebLogic.
App has been up since the third and... (2 Replies)
Hi,
I have a quick question.
How can I see MPXIO statistics (like errors, how many I/O|throuput per path, ....) on Solaris 10? Does maybe a ready dtrace script exist (I do not have the knowledge to write one myself)?
I would be happy if somebody knows some good documentation/links (with... (1 Reply)

I ran an fs_usage (based off dtrace facility) but someone closed the window I think.. But I still see the process running # 15023 I tried fg 15023 but it told me no job control.. Is there anyway I can see my output? The scan has been running an hour and the output is valuable to me. (3 Replies)
Can you tell me a command to show which file in the filesystem recently grew tremendously and then went back to its original size? I tried looking into dtrace disk i/o type commands but they take time to learn.. I want to know how to detect where in the filesystem the most drastic disk usage... (4 Replies)
I'm running on Solaris 10, and I have a script that's running on several machines. Basically, what it's doing is:
* tail -f | grep one or more log files into a temp file
* Every minute or so, copy that temp file to a second temp and zero the first
* Sed through the 2nd temp to pull out a user... (2 Replies)

Is there any way to create a file on Solaris 10 (ZFS preferably, but UFS would be helpful as well) with a specific inode number? I need to create a file with a large inode, greater than a 32bit integer.
