Hello, According to http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=4970596 and other notes I read it appears that the ability to run dtrace programs (by having dtrace_proc and dtrace_user privileges configured inside NGZ''s) has been made available (through various projects) since build 37 of Nevada. I am not merely referring to configurable privileges alone, but to

Hi, we are developing and operating an very critical application in the financial sector. Now our customer wants us to report performance data (roundtrip times of the messages routed). My idea is using dtrace to measure the times with the pid provider catching the timestamps on entry of the in and out functions of the processes. Now my questions ;-): 1) Is this an appropriate method to monitor

Howdy, I am trying to migrate several scripts to use application defined types, and am running into a few issues. When I attempt to run a script with a application defined type, it looks like the DTrace preprocessor is getting angry with me: $ cat view.d #include "httpd.h" :::acceptconnection { this->addr = (conn_rec *)copyin(arg0,sizeof(conn_rec *)); } $ dtrace -C

We just updated our configuratiosn to have multiple NIS servers, when we initiated a test of client failover, we were disapointed. It seemed that the only way to get a filaover was to /etc/init.d/ypbind restart. It behaves as indicated in http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=5084845 using ypbind-1.17.2-13 on Centos 4.5 / Linux xxxxxxxxxxxx 2.6.9-55.0.12.ELsmp #1 SMP Fri Nov

Starting OpenJDK 10, the 'javah' utility is no more provided [1], and its functionality is provided by 'javac' itself. Hence, do not error out on missing 'javah', and store whether it was found; in case it is not, then: 1) assume 'javac' has the -h parameter to generate the C header, and make use of it 2) tell the buildsystem that

This came up as an RFE during the conference (I believe it''s been logged as "4012008: brendan() action needed for DTrace Toolkit".) As everyone here is aware, DTrace is not quite as user friendly as it could be. For the uninitiated, it can be confusing to run a DTrace script and not see the expected output. Brendan Gregg has addressed this in the DTrace Toolkit[1] by

Hi, I was going through the implementation of the fasttrap provider. I found that when displaced execution happens (ie., when the instruction traced is being executed out of the scratch space) if an asynchrnous signal comes we need to defer the delivery. Can somebody explain why this is necessary and how is it implemented? Thanks in advance Saravanan S -------------- next part -------------- An

How do I query an application to see if it supports any USDT probe points?

Hi, I''m working on some performance analysis with our database and it seems that when the file system (UFS) is mounted with forcedirectio, the IO probe are not triggered when an I/O event occurs. Could you confirm that ? If so, why ? Seb -- This message posted from opensolaris.org

Hi, I have used dtrace in the past for diagnosing IO/filesystem related issues. So I am a bit familiar with dtrace scripts Now I want to diagnose performance problems in the java area. May be memory leak etc. The hotspot provider is not present. How can I get them? Does someone have any further advice? regards Hans -- This message posted from opensolaris.org

Hi All, I''ve got a problem when I have USDT probes in a static library and in the application code outside of the library. I build the static library containing some USDT probes, glomming everything together (ld -r) before creating the .a file to preserve the probe symbols. This all works fine. I build an application which also has some USDT probes. When I build the application which

Hello, everyone I am a newbie of DTrace and OpenSolaris. Just wondering is it possible to trace every memory read/write of a specific process given the pid? Basically speaking, I want to record the virtual addresses being accessed by the process, using which I will try to do some online analysis. If DTrace does not support this type of instrumentation, will other tools in OpenSolaris help me

I''m trying to install CiscoWorks 2.5 on Solaris 10 update 1, and after the install when I try to start the daemon, it errors: # /opt/CSCOpx/objects/dmgt/dmgtd.sol ERROR: open file dmgtd failedERROR >>>>>>>>>>>>> open msg catalog failed.

Hi - I''m trying to use plockstat to help identify any mutex contention issues we may have in our c++ app. >From the docs it would appear to be a very useful tool - unfortunately in practice this doesn''t bear out purely because the stack traces produced are limited to being 39/40 characters wide. In general this means that I''m not seeing ~75% of each stack symbol and

Using the following dtrace command, I can see who''s calling what with lots of +/- numbers: dtrace -n ''fbt:ip:ip_output:entry{@dbtypes[((mblk_t *)arg1)->b_datap->db_type,caller] = count();}'' ...the output is what I want but not how I want to see it. What I''d rather see is the function names associated with caller and for db_type to be output in hex.

Hi: I''m running Indiana (OpenSolaris developer preview) under parallels in OS X 10.5.1. I can consistently get Solaris to hang. Doing a dtrace -n pid\$target::malloc:entry''{@=count()}'' -c ls will consistently hang Solaris. Basically doing anything with PID provider with the -c option seems to hangs Solaris. Only way to recover is to stop and start Parallels desktop.

On Solaris x86, does zpool (or anything) support PATA (or SATA) IDE SMART data? With the Predictive Self Healing feature, I assumed that Solaris would have at least some SMART support, but what I''ve googled so far has been discouraging. http://prefetch.net/blog/index.php/2006/10/29/solaris-needs-smart-support-please-help/ Bug ID: 4665068 SMART support in IDE driver

I''m pleased to pass along news that the Mac OS X DTrace port has been updated in 10.5.3 to fix the issue that caused timer based probes not to fire in the presence of certain untraceable applications. http://blogs.sun.com/ahl/entry/apple_updates_dtrace A big thank you to the folks at Apple for addressing the problem.

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?
