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, If I release a new kernel module, do I need to release a SDT provider with it? Just like what "mdb" does - a mdb module together with the associated kernel module. Is it a "MUST" or a "OPTION"? Also what''s the requirement of USDT and user application? Is it encouraged or not to have many probes inside the code? Can I define my own

Hello, I''m having problems compiling Ruby 1.8.5 on a 64-bit Intel machine running Solaris 10 U3. I''m using Sun Studio 12 for building an optimized package for our company. We''re not interested in coolstack (from Sun used with GCC). Any help below would be appreciated: root@host # uname -an SunOS host 5.10 Generic_125101-08 i86pc i386 i86pc Solaris root@host # isainfo

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) AC_ARG_WITH(dtrace, AS_HELP_STRING([--with-dtrace=PATH], [Enable dtrace

Hi, I''m posting a question hoping someone will know the answer off hand thereby reducing my search time. :-) With USDT probes, the tracepoint is only installed by libdtrace itself, never by the drti ioctl. So whenever I run a program with an USDT probe, no tracepoint is installed. Only after I run the dtrace command the tracepoint is actually installed on the victim process. My question

I added a couple of static probes to Firefox to measure actual work done. I could have used a pid$target probe with a function name but work is done within an if statement, which is where I placed the static probes. I''m wondering about my use, though. Is the following significantly more efficient than pid$target::FunName:entry and return? I heard somewhere that $target does not

Hi, As I''ve discussed before whenever we add USDT probes to a C++ function and call dtrace -l we get the mangled C++ name for the dtrace function, being listed :( Now the point of USDT probes is to abstract a higher level semantic construct for users to make use of. Surely it is not meant to be listing Unstable Interfaces (implementation details), such as the containing C++

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

Hi people, When working with some usdt C++ probes we have come across a few issues. Controlling USDT Function name: Putting in usdt probes into C++ code gives you the mangled enclosing function name for the probes Function name. Working around this can be a pain. You need to wrap your usdt probes in extern C functions and call these. Could we have an option to control the Function name for

while trying to use the USDT made available to us in Postgresql database I have problems enabling them. On my database server I ran 1024+ PG processes (1024 clients). The server is a 8 core T2000 @1000MHz. 32GB. 7 storage arrays. Solaris 10 Update 4. Home compiled PG 8.3 beta 1 (optimized binary for T1 chip) with DTrace probes enabled. When running without enabling the probes I have approx 25%

Suppose I have a USDT probe in Firefox and that I''m trying to catch the startup with a probe like this: proc:::exec-success /execname == "firefox-bin"/ { start = timestamp; } and stop tracing when Firefox hits this USDT probe: mozilla:::main-entry { exit(0); } How do I put the running firefox-bin into "trace mode" so that my USDT probe fires? Thanks, Joel

[Perhaps someone could rename this list to dtrace-matt-problems-discuss?] If I run this script against my binary (which contains a USDT probe called ''concurrentq-latency''): ::: / probename == "concurrentq-latency" / { printf("[%s]:[%s]:[%s]\n", probeprov, probefunc, probename); } I get this output: dtrace: script ''testq.d'' matched 46056
