Programming :: Show The Top Processes Eating RAM In Human Readable?
Aug 14, 2010
I want to find out which process is eating RAM, I use this command:
Code:
ps -eo size,pid,user,command | sort -k1 -rn | head -10
but it displays with no human readable:
Code:
283364 4644 quanta /usr/lib/mozilla-firefox/firefox --sm-config-prefix /firefox-C3JYUC/ --sm-client-id 1014cd7d2d4000128169799000000044950019 --screen 0
230372 3635 mysql /usr/sbin/mysqld --defaults-file=/etc/mysql/my.cnf --basedir=/usr --datadir=/var/lib/mysql --pid-file=/var
[code]....
use 'awk' to convert 'size' column to human readable? I also read this thread but I get stuck in printing from $4 to NR.

I have log files that everyday are downloaded from my webserver in the format: Code: samplesite.com.xxxxxxxxxxx.gz xxxxxxxxxx is a 10 digit epoch time. I am trying to figure out a way in batch to:
1. find all of exisiting files containing the pattern (after the first run it will only be one a day)
2. Isolate the epoch string
3. convert the epoch string to human readable date/time
4. rename the original file as samplesite.com.mmddYYYY.gz

I want to display users quota in human readable format, so if the size is over 1 GB I want the quotas displayed in GBs
So when I issue the command below should I not get the results in GB ?
Code: Select allrepquota -sa
bob -- 87200M 400G 440G 879 0 0
dave -- 255G 400G 440G 3627 0 0
jim -- 10664M 400G 440G 230 0 0
tom -- 10737M 400G 440G 636 0 0
User bobs usage is 86GB, should 86GB not be displayed rather than 87200M?

I'm running several SHOUTcast server instances and a WowzaMediaServer instance on a CentOS machine. I'm experiencing a memory leak problem, but I can't figure out which processes are eating memory.
TOP command reports as follows:
[Code]...
Something misterious to me (I'm still a Linux newbie) is that TOP reports a total of 7.5GB used ram but very small percentage for single process (0-1%). Memory consumption starts at 1GB/8GB after reboot and in three days running gradually increases up to 8GB. I'm practising with Linux, but I still miss a lot to understand what's happening on my system. For instance, are there linux kernel logs saved somewhere that I can look at?

I am trying to show only the processes that use more than 10% of the cpu. I have managed to get it to show the processes in use using:
ps -eo pcpu,cpu,nice,state,cputime,args.
Then I am unsure how to sort this information so it only shows over 10%?

I am doing real time programming in C++, under Linux. I have two processes, let me say A and B. A process is being started periodically, every 5ms. B process is being started every 10ms. The process A is doing data processing. The process B is reading that data and displays it. I am confused about how to run periodically processes. The problem is that the period of process A should be as much as it is possible accurate (5ms). For the process B it isn't so important. I have created independent processes, each in one .cpp file, and I am starting them from bash file. Is that OK? I don't have to make child processes in order to have parallel processes?

I have 2 completely different processes A and B (they do not have any relationship) suppose A opens a file with file descriptor 4 and B opens another file with file descriptor 5
Can process A use the fd 5 (i.e using the file object of processs B) by any means..if suppose i let the fd 4 of process A to point to the file object of process B(fd 5) will it work? is it safe?

I have my code with my fork in a server and each time a client connects one more process is created. i use this code for the handling of zombies
void sig_chld(int signo){//Diadikasia gia tin diagrafi twn 'zombies'
signal( SIGCHLD, sig_chld );//signal gia ton entopismo tou zombie
pid_t pid;
[code]....
but i need the server to kill each zombie after the client is disconnecting and not to have to press ctrl+c

how to even start this Perl script. I have the following processes:
Command used to get this info:
ps aux --forest | grep -e process_name -e ksh | awk '{if ($1 == "user1" && $1 != "root" && $1 != "UID" && $1 != "xfs" && $1 != "mfg" && $1 != "mfgnet") print $0}'
Processes
user1 2819 0.0 0.0 4272 612 ? S Nov17 0:00 \_ -pksh-ksh
user1 2820 0.0 0.0 64956 1584 pts/833 Ss+ Nov17 0:00 \_ -ksh
[code]....
I need a way to kill off the pids 2819, 2820 because they do not have a process tied to them like pids 2918, 2922 and 6657. The way it works is peek shell (pid 2918)is opened then it starts a ksh (pid 2922) session then from there the end user runs a command (pid 6657).

I work on Linux for ARM processor for cable modem. There is a tool that I have written (as the job demands) that sends/storms customized UDP packets using raw sockets. I form the packet from scratch so that we have the flexibility to play with different options. This tool is mainly for stress testing routers.
The details are here.
I actually have multiple interfaces created. Each interface will obtain IP addresses using DHCP. This is done in order to make the modem behave as virtual customer premises equipment (vcpe).
When the system comes up, I start those processes that are asked to. Every process that I start will continuously send packets. So process 0 will send packets using interface 0 and so on. Each of these processes that send packets would allow configuration (change in UDP parameters and other options at run time). Thats the reason I decide to have separate processes.
I start these processes using fork and excec from the provisioning processes of the modem.
The problem now is that each process takes up a lot of memory. Starting just 3 such processes, causes the system to crash and reboot.
I have tried the following:- 1-I have always assumed that pushing more code to the Shared Libraries will help. So when I tried moving many functions into shared library and keeping minimum code in the processes, it made no difference to my surprise.
2-I also removed all arrays and made them use the heap. However it made no difference. This maybe because the processes runs continuously and it makes no difference if it is stack or heap?
3-I suspect the process from I where I call the fork is huge and that is the reason for the processes that I make result being huge. I am not sure how else I could go about. say process A is huge -> I start process B by forking and excec. B inherits A's memory area. So now I do this -> A starts C which inturn starts B will also not help as C still inherits A?. I used vfork as an alternative which did not help either. I do wonder why.
reduce the memory used by each independent child processes.

I am building a queue system (in C on CentOS 5) where each directory queue has a number of process instances 'watching' it. I have a root-permission queue supervisor process which does all the forking, and the instance processes give up root as their first action. For max security each queue is accessible to a different set of users and groups.
I need to keep the RAM requirements as low as possible, so I am relying heavily on copy-on-write (since all memory writes are to shmget() shared memory)
Each process presently dlopen's the libraries it requires after fork, but I'm wondering if I would gain by performing the dlopen before forking a number of instances which all require the same libraries.
Any pointers to mid-level tutorials on dlopen and fork internals would be most appreciated: this is about my third post anywhere since I converted to Linux, but I just can't find the answer to this anywhere online.

User 1 and User 2 each start a mono process with sudo:
"sudo mono user1.exe" "sudo mono user2.exe"
Each user has a kill.sh in their directory, which is being called by user1.exe/user2.exe to kill the process.
The script itself is
ps aux | grep 'mono user1.exe' | awk '{print $1}' | xargs kill
which in theory should pull *only* the PID of "mono user1.exe" and kill only that. The problem: It kills any and every single instance of mono that is running on my system, every userx.exe thats open. I am confused, as a simple "ps aux | grep 'mono user1.exe'" does only return the mono user1.exe process and not the others. "ps aux | grep 'mono'" returns them all though. how I can modify that script so that it only kills the specific process? Would "pkill -9 -f 'mono MCuser1.exe'" work as well - or would it too kill every instance of mono? I cant do a lot more of trial and error, its not good I am killing those instances accidently...

As an assignment i was doing a program to create two process using fork and pass messages between them using message queue.Did it worked well until my friend tried to copy it using scp.suddenly all hell broke loose as processes without ran syncronisation ie. in tech terms the process just wont wait wen a message queue is empty.it keeps on executing randomly.but after a reboot .. everything worked fine. until again i tried to do scp on my system on purpose. and again the program just went mad.

I have p1,p2,p3,p4 some processes created by me in C. p1, p2, p3 are started individually from several consoles. And I want process p4 to terminates processes p1, p2, p3 if they are running. Which is the easiest way to accomplish that? put all processes in the same process group and send from p4 a kill signal to the group. But I couldn't do that because I cannot call successfully setpgid(getpid(), 15000) from p1-p4. It's there some way to put them in the same group? the processes don't have a child-parent relationship, they are launched manually from consoles.

I have two processes that share a piece of memory, and i want to use the shared memory to send data from one process to the other. it's like a simple consumer-producer problem. when the producer fills the shared memory, it waits until the consumer can consume some data in the memory; the consumer needs to wait if there is no data in the memory. The thing gets complicated when both threads are allowed to sleep and wait for the other to wake it up.
i wanted to use condition variable of pthread for synchronization, but it doesn't work in multiple processes. i tried semaphore, but it's quite complicated and i still cannot make it right. I believe it's a common problem and someone should have written similar code before, or maybe the code is even wrapped in a library, but when I search for it on Internet, I only found information about how to share memory between processes. Does anyone know where I can find this kind of code or library?

I have a program that receive user input.
I want to run this program automatically without user interaction, and in order to do that I need to simulate key events.
How can I do such a thing?
The program I am running is partly java and partly shell.
The shell part is easily done by using:
./prog.sh <parameters (Parameters being a file containing parameters)
But the java doesn't work similarly.
