Hello Srikant - A quantization distributes the results of your aggregation into ranges ordered by a power-of-two. Presumably what you''d do in your script is capture the inclusive elapsed time of each function call in your library, then use this quantization to see how tightly-banded the times are. Perhaps there''s some blocking I/O in some of your calls, for example, in which

According to this page, http://www.apple.com/macosx/technology/unix.html In addition, Java, Ruby, Python, and Perl have been extended to support DTrace, providing unprecedented access for monitoring the performance characteristics of those languages. When I do dtrace -l | grep -i perl on MacOSX 10.5.2. I don''t see any perl providers so I am not sure how I could monitor perl scripts via

The earlier post with the Dtrace probes definition (sent on April 23) was only to solicit feedback from all prospective users of iSCSI DTrace probes. I will follow up shortly with an updated document requesting approval from the community. thanks Priya -------- Original Message -------- Subject: Dtrace provider for the COMSTAR iscsi Target Port Provider - Review Request Date: Thu, 23 Apr

DTrace folks, I''m pleased to introduce a potential new DTrace-sponsored project: the Erlang DTrace provider. To be good OpenSolaris citizens, we want to put the formation of this officially sponsored project to a vote -- as outlined in the OpenSolaris Constitution -- so here are the details for the new Project, as prepared by the Project Team: Name : Erlang DTrace Integration

This is from a discussion on opensolaris-tools that is somewhat relevant for DTrace community. I wrote a simple D script (http://www.opensolaris.org/os/project/onnv/onnv_build/faster_builds/tools/dtrace/dirtrace.d) that collects data for each dmake process during the Solaris build. After that the data is post-processed by a Perl script

I''m trying to profile the time spent in libc functions in a large build job (building Perl), and I have trouble getting ufunc and func working. (func() is not strictly needed; I was just hoping to use it in order to profile idle time.) Here''s the story. I''ve written a dtrace script to start a separate dtrace process for each invoked command: int fileid;

The open solaris dtrace page (http://www.opensolaris.org/os/community/dtrace/) has a bad link to the DTrace Guide(http://docs.sun.com/db/doc/817-6223). This message posted from opensolaris.org

Hi there, I''ve been using OpenSolaris for three months now, and I''ve started to get interested about to get my hands dirty with DTrace. Since I have an strong GNOME background, I would like to use it to help GNOME developers to find performance problems. Federico Mena Quintero, one of the Novell GNOME guys is one of the people that are working on GNOME performance stuff. He

Hi, I am kind of new to DTrace , I have written a script to time function calls in our application library , Wanted to know how to interpret the output from quantize of the elapsed time in each function call , here is a sample Here is the entry and return function for the library that is being traced pid$1:libswduar::entry { duarEntry[probefunc] = timestamp;

It''s quite difficult, though, to predict what DTrace features one will get when installing Solaris 10 (whatever release). There is nothing about the fine details of

In the past I used a tool called WHAM to collect system and process information from Solaris. It looks like dtrace could replace WHAM. Below are the counters that I got from WHAM. I got cumulative and instantaneous counts. Is there some existing dtrace script that will give me all of these plus even more? Also, WHAM was distributed, that is it could collect these counters from multiple

hello! First of all thank you for all your information you give us on this sites. It is a great help to learn for example dtrace. i''ve a little script in work, which shows the cpu utilization per process in percent. this output is refreshed every 2 seconds for example. now i want to extend this script with the output of the allocated bytes of memory per process. how could i display this

Dear dtrace Experts, I have seen some dtrace utilities like opensnoop and execsnoop etc. My interest is to write a simple script that can snoop the files which uses the 3 syscalls like open,create,unlink. I have gone through dtrace oneliners that can do the same : dtrace -n ''syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0));}'' dtrace -n

I want to print out arguments of float and double type, such as from sin(), cos(), etc. By trial and error, I came up following macros. union { double d64; float f32[2]; int64_t s64; int32_t s32[2]; } VALUE; #define PRINT_F32_sparc(val) \

Hi All, One of the customer is seeing the following error messages. He is using a S10U1 system with all latest patches. Dtrace script is attached. I am not seeing these error messages on S10U2 system. What could be the problem?

I have inserted some probes in my application, and it works great in the "debug build" I have been using. So I wanted to look at the "overhead" introduced by inactive dtrace probes in my application. I am using the Sun Studio 11 compiler, so I added the following options: -xO5 -g0 -xbuiltin But this breaks the linking of my application. Undefined first
