similar to: dtrace: failed to grab pid 16537: process is traced

Dtrace does work on some workstation, such as as follows, ----------------------------------------------------------- bash-3.00# dtrace -s ./mem.d `pgrep test` dtrace: script ''./mem.d'' matched 5 probes ^C bash-3.00# uname -a SunOS ftp 5.10 Generic_118833-17 sun4u sparc SUNW,Sun-Blade-100 bash-3.00# dtrace -V dtrace: Sun D 1.1

We are using following dtrace script to analyze an application. However we see different number of lwp_yield and yield calls reported depending on whether we trace mutex_lock or mutex_unlock or not. The number reported when we are not tracing mutex_lock or mutex_unlock is higher. What could be going on here and which one is the correct number. This is on S10 U2. Thanks, Rao.

[1] Predicates in one-liners I would like to list the probe modules in my executable and then dynamically create a dscript to trace execution of those modules alone (by excluding the 3rd party and system libraries). I tried the below script without success. The conditional given in the predicate is not taking effect. Why is this so ? $ dtrace -ln ''pid$target:::

My fame package has a function that checks to see if a FAME SERVER process is already running. On Linux, I can do this in one of two ways: pid <- Sys.getpid() user <- Sys.info()["user"] cmd <- paste("pgrep -fU", user, "-P", pid, "'FAME SERVER'") fameRunning <- as.logical(length(system(cmd, intern = T))) or I can use cmd

I have a script that runs as a cron job every minute (on Ubuntu 10.10 and R 2.11.1), querying a database for new data. Most of the time it takes a few seconds to run, but once in while it takes more than a minute and the next run starts (on the same data) before the previous one has finished. In extreme cases this will fill up memory with a large number of runs of the same script on the same data.

Greetings, is there a way to specify probes and other dtrace operations via command line parameters, like " BEGIN { usr_exec=$$1; usr_syscall=$$2; } syscall::usr_syscall:entry /execname == usr_exec && guard++ == 0/ { ... " [this does not work] This would make it possible to create "generic" dtrace scripts. Otherwise, some shellscript with sed-magic would

Hey all, I'm having a little bit of a weird issue on my web host. I was just wondering if anyone's seen anything like this before. The problem is that you can't seem to restart apache via the stock init script that comes with apache: [root at beta:~] #service httpd restart Stopping httpd: [FAILED] Starting httpd: [Mon Mar 03 11:21:14 2014]

I''m curious to know what files are being used from a NFS server perspective. I''m unable to trace the client because it is in the boot phase. Looking at the io provider, I believe it does not allow you to look at what files are being requested. That would lead me to the fbt provider. Does anyone know what fbt provides the file handle for NFS client request on the NFS

Hey Listees, I have a question (hopefully quite simple) about the system V init scripts in /etc/init.d. I have an app installed and for some reason it had no system V init script. It has been installed a long while now so I can't quite remember whats going on but basically I remember I wrote the init script my self and the app is enabled as a service which chkconfig to run at system levels 3,

Warning - I'm fairly new to libvirt, lxc and systemd so there is a good chance I'm doing something terribly wrong here. However, instead of continuing to struggle, I figured I would mail the list for some advice. What I'm trying to accomplish is a libvirt-lxc, systemd-based container running on my system (Fedora 19). I've read that sharing the underlying OS filesystem with

Hi there, I have an X-Lite phone on my box and I'm trying to register it with a remote Asterisk box. Both the X-Lite and Asterisk are behind a NAT. I know it's a pain to do because of SIP not working well with NATs, but I know there are ways to do such a thing...moving the Asterisk box outside the NAT is not a possibility at the moment. One thing we tried was setting up a VPN, but

Hello, I am not sure if I trigger a bug and if so it could also be in ruby sqlite3 backend. However, maybe I do something totally wrong. I have the following part in puppet.conf: [master] storeconfigs = true dblocation = /var/lib/puppet/state/clientconfigs.sqlite3 dbadapter = sqlite3 Now every time a client (agent in puppet speak) is run I get one more connection to the

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

Hi, for a job of lesser priority I would like to connect to a Samba server. When I'm doing a 'smbmount', enter the server by SSH, pgrep for the new smbd process and then renice it I have exactly the behaviour I desire. Now I would like to automate this and yet start the server process with lower priority. Connections to other clients shall not be touched at all. Are there any
