Hi: I got OpenSolaris 2008.05 running as dom0 under VmWare fusion on my MacBook pro. Using the instructions from Dipleep''s blog http://blogs.sun.com/dkumar/entry/how_to_create_domu_in Everything seems okay except the networking. When booting OpenSolaris (without dom0) the pcn0 interface works just fine but when booting Solaris xVM version them pcn0 does not work (ie) I get failures

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

Hi all, I remember at OSCON 2005 there was talk of adding DTrace probes to PHP (in fact, I have a photo of Bryan and Wes working on it!). Did they ever get into the upstream branch, ''cause I don''t recall seeing a --enable-dtrace (or similar) configuration option when I recently built PHP 5.2.1. If not, is there an ETA?

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.

Hy! I receive an nxge driver messages on console: Aug 18 11:08:42 [hostname] nxge: NOTICE: nxge_ipp_eccue_valid_check: rd_ptr = XXX wr_ptr = YYY I find the bug description/correction at sun web page, and i know i can ignore it. I thinking about how can i delete from console only these messages (here is my first version, what is not (so) elegant): #!/usr/sbin/dtrace -qs #pragma D option

Hi Folks, I''m trying to use DTrace to understand some complex code using the user process probe. Things are basically not matching up. When I use a variable to track depth, sometimes it jumps. Similarly, the flow indent seems off. I read another post saying that this is caused by missing return statements in functions.

Hello, I''m building some simple monitoring tools to watch zfs storage servers. Is this possible to run dtrace script for example 10 seconds? (Of course it is, I just trying to figure out how). Right know it has to be stopped by "CTRL-C" I''m particulary interested in scripts like iscsiio.d, iscsiwho.d from

...ht forward issue and I''m missing something obvious. I''m trying to print a wchar_t [] argument from a simple example program like #include <stdio.h> #include <wchar.h> #include <unistd.h> void prout(wchar_t *wstr) { } int main() { wchar_t name[]=L"Angelo Rajadurai"; int i; for(i=0; i<1000 ; i++) { prout(name); sleep(1); } } With a D script like #!/usr/sbin/dtrace -s pid$target::prout:entry{ printf("Argument of %s is %s\n",probefunc,copyinstr(arg0)); } but it just prints the first char of the string "A" I...

Hi, I am adding DTrace probes within NFS v3 client. In my current implementation, I use some tsd_*() functions and kmem_zalloc() function. These functions might be heavy and affect the performance. I want to call this function only when DTrace is running or the DTrace probes are enable. So is there a way to check DTrace is running or DTrace probe is enabled? Regards, Danhua

If I use a simple dtrace script such as this: fbt::somefunc:entry{self->trace=1;} fbt::somefunc:return{self->trace=0;} fbt:::entry{} fbt:::return{printf("%lx", arg1);} then it will descend to whatever depth is necessary If I want to limit it to say 3 functions deep, how can I do that? The quick answer I want to use is to do "self->depth++" on each entry and then

I use a lot of tabs and Firefox runs very slowly. I would like to figure out which tabs are eating up resources (cpu, memory, etc). Will the Mozilla dtrace framework be any help with this? -- This message posted from opensolaris.org

Hi, I am tracking down a problem and would like to know how I can follow a forked process with my dtrace script, or how I can trace a dynamic library. Here is the problem. I am tracing dtlogin, and specifically I am trying to determine what error libpkcs11`<routine> is returning. It turns out dtlogin forks a lot of processes, and I believe the second forked process is the one that winds
