General :: Find Out How Much Time An Already Running Process Is Spending In User And Kernel Spac?
Jun 8, 2011
I am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.
I am trying to set the umask for a process(orkaudio) which is running as the root user.This program creates dir and files and I need the umask to be 022. I have edited my /etc/bashrc -- and when i type in umask i get 0022 --- Not sure how to go about getting this resolved...

I have an Acer Aspire netbook with 1GB RAM and 1.6 GHz dual-core 32-bit x86 chips. The KPackageKit / yum / rpm chain is running too slow for me. In addition to the time required to download any new packages or updates, it seems to require at least one full minute of processing time to install each package, update, or bug fix, no matter how small. Another full minute is consumed for each package in "cleaning up."Running yum from the command line takes nearly the same amount of time.During this time, I cannot run any other applications without severe thrashing. It seems that a full gigabyte of memory is in use with some 100M swapped out to disk.
Is there any way to reduce the running time and memory requirement of the update process?While not updating or installing software, I do not normally run out of memory (i.e. begin thrashing) until I have about a dozen browser tabs open, or the like.
i am using Ubuntu 10.04.1 LTS. i only ever contact my ubuntu machine through SSH. everytime i login, i do:
this launches the dropbox process and all is great. except when i log back into the ubuntu machine via ssh after a few hours, the process no longer exists. how can i get the process to run indefinitely?
I am trying to write a script that will look for a plugin and check that its running and if not start it Code: ps ax | grep -v grep | grep aseco.php The above should list the process, if I put it into terminal this is incorrect?
i googled around and finally stumbled over this forum. I've been wondering, how would i kill an process running from an folder and with user parameter? I usually type this into the ssh console: pkill -9 < process > -U < username >
But i want users be able to run it multiple times, and killing only an specific process and not every single one.
Is It possible to change a process running in root-user to non-root-user by setting suid / uid / euid / gid etc... I so please instruct how, when and wat to set in order to change a process running in root-user to non-root user
I am trying to find the dyanmic heap size and stack size of a running process in rhel5.5 and rhel6.I read that the 23rd parameter in the file /proc/pid/stat gives the heap size.Can you elaborate more on this.Also is there any other way to do this?
I am writing a program which i dont want the kernel scheduler to preempt before certain time duration. I am using the system call sched_get_priority_max to set the maximum priority. However it is not producing results.
I am searching for a Linux user level command/utility to measure the network bandwitdth used by a specific process by usig its process id.i used different commands like, iperf, ntop, netstat etc, but it doesn't to meet my requirement. i need to observe network bandwidth used by only a specific process .
I have the latest release of Lucid Lynx installed. I want to try out audio recording on Linux so I want to know if it's possible to use a real time kernel with Lucid. So I installed the 2.6.31 real time kernel. It shows up in GRUB, but when I boot it gives me the message:
mounting none on /dev failed No such device
It then takes me to the login screen, and once I enter my password it just takes me back to the login.
This morning I ran the automatic upgrade provided on the repositories, updating my kernel from 2.6.38-8 to 2.6.38-10.Unfortunately, upon reboot I discovered that a series of patches I'd applied in order to get my wireless card on my desktop working had been undone (see I had to run a modified version of the instruction set in order to get my wireless back on.My question: is there a way to trigger this every time the kernel upgrades? I'd hate to have to run this cumbersome set of commands manually every time.
I started to use linux (CentOS 5) 1 week ago. And I took lot of imformation from this forum. Is it possible to install two program at same time? Total download size: 67 M Is this ok [y/N]: y Downloading Packages: jdk-6u24-linux-i586.rpm 19% [========-] 6.0 kB/s | 13 MB 153:51 ETA It is so boring to wait and I have to wait there is nothing to do something else just centOs text.
I want to limit the time a grep process command is allowed to run or be alive.For example. I want to perform the following:grep -qsRw -m1 "parameter" /varBut before running the grep command I want to limit how long the grep process is to live, say no longer than 30 seconds.How do I do this?And if it can, how do I return or reset to have no time limit afterwards.
Centos 5.4 64bitWould like to know when a particular process was started.1.Quote:ll -d /proc/4014/dr-xr-xr-x 5 mysql mysql 0 Nov 28 07:34 /proc/4014/2.Quote:ps -o pid,lstart -p 4014 PIDSTARTED 4014 Tue Nov 17 23:10:13 20091) Which one should I consider?2) why do both have such a difference?
Is it possible, using ps, to determine where a process is running from? I have two applications, both are identical and running in parallel directories, such as /app1/start.sh and /app2/start.sh. If I run ps -ef then I'm unable to tell the difference between the two
Using ps (or alternative), how can I tell that PID 123 belongs to app1?
