similar to: Erlang DTrace Provider

All, With Jon Haslam''s exciting news about the DTrace doc wiki (if you haven''t seen it yet, make your way to http://wikis.sun.com/display/DTrace), and with some of the discussion with the Apple folks, I''m wondering if the time isn''t right for something of a DTrace summit, perhaps as an unconference. The idea here would not be a DTrace user group (though that

G''Day Folks, I''ve finally typed up my classic DTrace demo, which I use to introduce people to DTrace (I delivered this at SOSUG#1), http://www.brendangregg.com/DTrace/dtracevstruss.html Here I create a fault and show the difficulty in analysing it using previous tools. Then I compare the impact of analysing the problem using both DTrace and truss. DTrace wins (a lot!).

Hi, This is not a DTrace technical question (so, please don''t flame me for it) :) This is regarding the DTrace (un)conference TShirt. I am curious to know what engine is it. Could not figure it out.

Unless I am missing something I cannot find a way to do a condtional check and handle it when a dtrace script is written with macros $1, $2 being passed to it, etc... In other words I have a dtrace script that can have parameters passed to it. Lets say $1 and $2 for example. I am trying to verity that there is or is not a value for $1 or $2 and adjust accordingly. I am finding that if use macros

So I realize this is somewhat stupid, and I''ve actually gotten myself out of kmdb to kill my dtrace script but this has happened in the past and I''m wondering if there''s any better way around it than hitting :c a bunch of times. Say you set a breakpoint() to fire in a common function. This will drop you into kmdb where you can do some debugging, you take a look around

For those of you following the IBM vs SCO legal case, you have probably noticed that SCO has said that the GPL is invalid. IBM appears to make the reasonable case that you can't say something is void, and then rely on it. INAL, but why is SCO allowed to distribute Samba without agreeing to the GPL? That's like buying a car, then claiming the sale agreement is bogus but you still want

I''d like to see if we can use DTrace to as the kernel implementation of the BSD systrace security policy system (http://www.systrace.org). I don''t really want to port systrace to Solaris because I think with DTrace we already have all the necessary in kernel hooks to do this. With systrace you express things like: "httpd can bind to port 80 but not any other port, it

It's not possible to define an action which takes a parameter called 'message' because the Erlang bindings use that as the name of an internal variable. Solve this by renaming the Erlang internal variable.

Hi, Following Chris' advice, I will rebase the patches and break them in 3 distinct emails (one at a time) in order to be easier for a reviewer to approve/comments. Please note that the three patches while being code-wise independent, they 're strongly-connected *semantically*, meaning that including just a subset of these patches to LLVM's code base is quite weak if the others are

Hi, We 've been working on an LLVM backend for High Performance Erlang (HiPE) [1], the native code compiler of Erlang/OTP [2]. ErLLVM [3] targets the X86 and AMD64 architectures for now but there is some ongoing work from a team on the Uppsala University to also support ARM. In our implementation, we have paid special attention on retaining ABI-compatibility with the Erlang Runtime System in

There is a Slashdot discussion today titled "Cambridge Researcher Breaks OpenBSD Systrace". Slashdot anonymous member has a comment "Even Sun''s Dtrace might be vulnerable." I don''t think it is.

I'm beginner with R language My goal is to write a function that takes an input Erlang entering your ? Name ? Name ? Date of birth. The program will calculate age and display output first I do know the system date (month, day, year) I find with Sys.Date () I found a function. net to calculate the age Protected Sub calcul_age() Dim datetimenow = DateTime.Now Dim

Hello, How would you implement an Erlang feature such as the ultra-light processes? Is llvm prepared for similar situations? I would appreciate some insight on this. Thank you very much, .alvaro.castro.castilla.

I have a number of systems running solaris10 and i see the package and binary for dtrace installed however whenever we try to run anything we get this error dtrace: failed to initialize dtrace: DTrace device not available on system the only system in which i dont have this error is the development server that has the full solaris 10 install while others are minimized, do i need additional

Hi Álvaro, Your question is too vague to answer with any accuracy.
