similar to: DTrace merged ready for 7.1

Hi Dean, I haven't looked very closely at XRay so far, but I'm wondering if making CTF (common trace format, e.g. see http://diamon.org/ctf/) the default format for XRay traces would be useful? It seems it'd be nice to be able to reuse some of the tools that already exist for CTF, such as a graphical viewer (http://tracecompass.org/) or a converter library

Hello everybody! How do people generate the Compact Type Format (CTF) section? Do you have a special parser or employ gcc debug information? Is there any open utility to do this job? Best regards, Yaroslav

I would like to know how to get access to errno when using pid provider to probe calls to libc functions like fopen(). The built-in errno appears to be only for system calls. What I''d like to be able to do is investigate where in an application I''m encountering EMFILE and what the stack looks like at the time. This message posted from opensolaris.org

I have a script where I can freely reference struct nameidata*, struct vnode*, etc. on Snow Leopard. How does DTrace know about these data types? I understand things like #pragma D depends_on library darwin.d where darwin.d has typedefs. I can''t find definitions of nameidata and vnode in any D scripts, though. How does it work? Thanks, Joel --- firefox for android!

Hi. I''m happy to inform that the ZFS file system is now part of the FreeBSD operating system. ZFS is available in the HEAD branch and will be available in FreeBSD 7.0-RELEASE as an experimental feature. Commit log: Please welcome ZFS - The last word in file systems. ZFS file system was ported from OpenSolaris operating system. The code in under CDDL license. I''d

OK, I am trying to dtrace isp(4) module in freebsd 7. each obj file is converted using: ctfconvert -L VERSION isp_freebsd.o and using "ctfdump isp_freebsd.o" I can see CTF info embedded in the .o file but in the linked kernel module, I found much less CTF info inside it. I guess I should use "ctfmerge" to combine the CTF info from each obj file into the final kernel module,

Hi llvm-dev, Recently, we've committed the beginnings of the llvm-xray [0] tool which allows for conveniently working with both XRay-instrumented libraries as well as XRay trace/log files. In the course of the review for the conversion tool [1] which turns a binary/raw XRay log file into YAML for human consumption purposes, a question arose as to how we intend to allow users to develop tools

I want to go a lot deeper with my tracing of MySQL and to do so I want to look into MySQL Thread Descriptors (class THD). Inside is a great bulk of information utilized by a great many of the core functions within MySQL... I really want to get in there. So far I''ve had no luck though. It''s a C++ class, and I''m afraid that I''m approaching it like a C struct,

Hi all, OK, so this at first looked like a clear cut "Don''t do it, or at worst handle the results" issue my customer has come to me with, but the more we discuss it, the more it looks like we should have better ways of dealing with this issue. > We have user defined dtrace probe points in the application which use > as parameter 64 bit values: > > provider adv {

Hi R-friends, Attached is the SAS XPORT file that I have imported into R using following code library(foreign) mydata<-read.xport("C:\\ctf.xpt") print(mydata) I am trying to maximize logL in order to find Maximum Likelihood Estimate (MLE) of 5 parameters (alpha1, beta1, alpha2, beta2, p) using NLM function in R as follows. # Defining Log likelihood - In the function it is noted as

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?

My leaky memory says we moved entry-point into some form of debug record in the standard libraries, circa Solaris 8/9. Before that, my group maintained text files that listed all the entry-points and their parameters for libraries like libc.so, so that we could print out parameter values in apptrace(8). There''s a (small) chance the records are complete enough that dtrace could use the

Hi, I''m trying to be really, really sure that a specific service is not running. The central part of this looks like that: service { ''foo'': ensure => stopped, enable => false } -> package { ''foo'': ensure => purged } The astute reader will notice that on the second run puppet will complain that the init script for foo is

Hi, I am trying to trace some functions that are executed at detach time, and it seems that just having dtrace around to instrument the module is causing a short circuit, whereas modunload will return (device busy). I understand that this makes sense, but how can I get around this if I want to trace stuff at detach time? Thanks, --S
