hi, I am trying to find out the avg cpu time spent in each of my user methods (exclusive of other methods invoked by a method). Hence the following snippet failed miserably: ----------------------- pid$target:a.out::entry { time[probefunc] = timestamp;} pid$target:a.out::return { @spent[probefunc] = avg(timestamp - time[probefunc]);} END { printa(@spent);} --------------------------------- Sample process int g(){} int f2(){g();} int f(){f2();g();} int main() { f(); } ------------------ sample output: g...

Why is this so ? $ dtrace -ln ''pid$target::: /probemod!="libc.so.1"/ { printf("%s ----- %s",probefunc, probename); } '' -p `pgrep a.out` Similar is the case for the below script, I expect only the entry points to be printed but all the probes in a.out are being printed. $ dtrace -ln ''pid$target:a.out:: /probename=="entry"/ { printf("%s ----- %s",probefunc, prob...

I''d like to be able to dynamically read external configuration files within a dtrace script. I know dtrace allows inclusion of C header files but only at the preprocessing stage. What we need to do is dynamically enable/disable probes based on current application settings. I''d rather not have a bunch of independant scripts running and being started and killed whenever the

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? Als...

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.

Referring to the DTrace manual: "Module If this probe corresponds to a specific program location, the name of the module in which the probe is located. This name is either the name of a kernel module or the name of a user library.

The goal we try to achieve is trying to get insight if there is a bursty nature in the time slot when system calls are done.

Counting the number of read and write syscalls that fall in each slot. This one is run a...

I''m wondering if I should file a bug against this or is this just a case of a user doing something stupid :) I ran the following script on my desktop: #!/usr/sbin/dtrace -s pid9276:::entry { @counting[probefunc] = count(); } And my Xsession immediately crashed and through me back to the login screen. My OS is 5.11 snv_50 i86pc i386 i86pc with a dual core amd chip and 2G or memory. pid 9276 was Xorg, in case you couldn''t guess. So is this something that dtrace could/should have prevented or i...

Hi all, Is there some documentation or some example on how to interpret the arg0 .. arg<n> for the aioread, aiowrite, aiowait syscalls? The system call name for all three seems to be "kaio".

We''re running a Solaris 10 container, with an Oracle 9.2.0.4 database - every 5-10 min, an Oracle process shoots up (using 20% + CPU) and then goes down in CPU %, doing a [i]pollsys [/i](see it via dtruss). I tried using some of the trace scripts in the Dtracetoolkit to see what the process is doing, but without any luck - also tried with the following, but dtrace process goes up to 30%
