Can dtrace agent of JDK be used in IBM Websphere?(fwd)
------------------forwarded------------------------------------
This is to help my customer to migrate their IBM websphere 6.0.2 to run
on solaris 10 platform.
Customer is eager to use the dtrace agent of JDK
(https://solaris10-dtrace-vm-agents.dev.java.net/ ) to benefit their IBM
websphere server, I am not sure whether we can use this agent in IBM
websphere bundled JDK whose version is JDK

more friendly "dtrace --actions" , "dtrace --aggregations", "dtrace --varib
To remember all dtrace actions, aggregations and variables is a headache, even worse, they are not include in dtrace(1M) now.
So here is a chance to have a CLI RFE -
to have something like "dtrace --actions", which will list all actions, like this page:

Analyzing java class loading with dtrace
Hi there,
I am trying to diagnose a performance problem on a Sun T5120 running
Solaris 10. I see general poor performance using Java and, in
particular, loading classes. I have developed a simple java test that
loads all of the classes in a Crystal Reports JAR file (around 7000
classes) which takes much longer on the T5120 (40 secs) than on a Core
2 Duo windows PC (5 secs). I recognise that this

autoconf test for building dtrace USDT probes?
X.Org has adopted GNU autoconf as its build configuration mechanism,
so when I integrated the dtrace probes, I checked to see if they
should be built using this test, checking for the existence of a
program named "dtrace" in the path:
dnl Check for dtrace program (needed to build Xserver dtrace probes)

Dtrace Snooping
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

Duplication in dtrace''s forceload entries in /etc/system
Hi,
If you have a custom kernel (and therefore have duplicates of
everything in /kernel in your custom kernel) and have noticed that when
you try to use anonymous tracing, dtrace adds multiple copies of the
forceload directives to /etc/system, e.g.:
* vvvv Added by DTrace
*
* The following forceload directives were added by dtrace(1M) to allow for
* tracing during boot. If these

dtrace doesn''t trace some functions
Hello,
I''m trying to debug an issue with rpc.metad on Solaris 10, basecally I
believe the failure path is
- svc_init
-- check_sys
--- check_host
---- strcmp(hostname, mynode())
It seems that for some reason hostname and mynode didn''t match then I
would like to use dtrace to show the argument of the strcmp
However the dtrace pid provider can''t trace functions

about use dtrace analyze tomcat''s situation
everyone Here:
How do you do!
dtrace is interesting. I am studing how to write dtrace script and analyze situation.
I read dtrace_example.pdf and 819-6959.pdf document more than five times with careful.
because I am newbie to studing dtrace.so I still don''t know how to begin.
for question:
1. What consumes time?
2. Which system call(s) consume(s) time?

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

I/O size distribution?
Hello
I have read that under Solaris one can use DTrace to get I/O request
size distribution on a global scale (also on a per process/pid basis).
See for example
http://prefetch.net/articles/observeiodtk.html
Can anyone?recommend?an alternative to get similar information under
CentOS? I looked into dtrace for linux but it seems still work in
progress, even putting aside CDDL issues ...

Re: Debugging Linux binaries with Dtrace?
Hi Nils, all,
I tried the ''FBT-trick'' suggested below by Nils and (of course :-) ) it
works and gives me a pile of output. Good enough to show that indeed Linux
application behavior is not totally opaque, good enough to for instance show
that ''system call mapping'' is taking place.
I wonder, is there any documentation available for lxsyscall module ? To
