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 using the below dtrace script to capture the flow and times of kernel functions, from an ioctl() call. After an entry into restorectx(), the trace of startimestamp - vtimestamp makes a dramatic jump downwards. Here''s the snippet showing the jump... 6 -> di_checkmem 8 220176600 6 <- di_checkmem

Then maybe more of the error can be captured. I grepped for Inva in the source code. There are lots of error messages which start with this which are sent with error() or fatal() or

Hello all, I saw this question about a year back in the archive[1], but with no final answer. I would like to trace shmget calls and also get the id of the shared memory segment. That script looked like[2], but we dont get the id since arg1 is the errno value. How do i access the shm id, i would need this to debug a customer problem but i don''t have time to learn it the hard

Hi, I need help in calculating Java method time-stamp in following fashion. Consider following method example. long method3(long stop) { try { Thread.sleep(1500); } catch (Exception e) { } //////////////////// real CPU intensive operation /////////////////////////// for (int i = 1; i < stop; i++) { stop = stop * stop * i; };

Hi all i need urgent help our entire switchboard is down only 5 days after it came up. this is the second time this has happened and i am thinking that asterisk is not worth the trouble it gives. mostly it runs without hassle. but around 2 weeks ago during the test phase we rebooted the machine and did the normal modprobes and this error popped up. coming back to work after the weekend the

I have a cron script that polls various machines for their configs and archives any changes. When it connects to an OpenWrt router running "OpenSSH_9.1p1, OpenSSL 1.1.1s 1 Nov 2022", it sometimes gets this error: Bad packet length 1231976033. ssh_dispatch_run_fatal: Connection to 192.168.8.1 port 22: message authentication code incorrect What's odd is that the length is *always*

Is there any way to get printf type functionality inside the kernel from dtrace probes. Basically I want to dump progress through flow in my device driver. Something like: DTRACE_PRINTF("Inside chip reset, mailboxes %x %x %x %x %x %x %x %x", mb1, mb2, .....); ... ... DTRACE_PRINTF("reset failed: reason %s", failure_reasons[err]); I may have several such probes and they may

One thing that can cause this is if the libc writes to stderr (ie fd 2) on some classes of error. This is something libc should probably not do, since

Please do give reproducible example. The code you gave, which you claimed `works correctly' doesn't: > SDT.Optim <- function(crit = NULL, Hess = F) + { + q <- length(par); x <- data + if(hasArg(crit)) + cat("\n Crit present\n") + else +

I''m trying to time a function within Firefoxwith a pid$target probe [2]. e.g dtrace -Zqw -x dynvarsize=64m -x evaltime=preinit -p 13954 -s menu- construct.d -s sigcont.d elapsed: 12.7942481ms cpu : 7.7911194ms count : 40 times I''m also measuring Firefox startup time by running it arguments like this: ... file:///Users/joelr/work/mozilla/startup/startup.html#`python

Hi, Yufei: Thanks for your kind action. Let me centralize all the harm-hearted guys and involved alias in one email. Below is the answer of your question (Can you reply with more details on what failed? Does websphere use an IBM or Sun developed SDK? ) 1. Seems IBM bundled JDK can not detect agent options, like below: If use Sun JDK 1.5, no problem: /usr/jdk/jdk1.5.0_06/bin/java

Hey, Do you guys think that is a good idea to have a manual page for each provider with a complete description of what probes are offered ? Found some already under 7D category: dtrace dtrace (7d) - DTrace dynamic tracing facility fasttrap fasttrap (7d) - DTrace user instruction tracing provider fbt fbt (7d) - DTrace function boundary tracing provider

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

I''ve recently got a new modem. In fact, it''s a modem-router with NAT functionality. Before I had a plain modem-modem, and I was able to access my workstation from my remote server using the IP address assigned to me by my ISP. Now however, that IP address only reaches the modem-router and the IP address of my workstation is set by my modem-router to 192.168.0.2 How can I

Hi, I want to use USDT in my java applications. Please tell me how to achieve this. I am comfortable with SDT in C application. I am using Solaris Sparc10 with Generic_120011-14 version. Do I need to update my machine for this? Thanks, Ajit -- This message posted from opensolaris.org

Hi all, (CC''ing dtrace-discuss as an FYI+workaround) I''m using dtrace -h to define provider probes for my application, and it wraps the resulting probe provider definitions in an #if _DTRACE_VERSION. Everything works fine for cc/CC, but gcc/g++ (gccfss v4.2.0) doesn''t seem to define it and the provider call macros expand to nothing instead. A diff shows that gcc uses

Hi, I have mentioned before that we have added some sdt dtrace probes in SAX, our APL interpreter. Encouraged by Angelo and Jignesh, I have created a small document (5 pages) describing our experience with it, together with some problems we have encountered and some scripts we use for pretty-printing dtrace outputs. The said document can be found at
