I have a process that runs without creating a PID. I know how to use pidof... So I use it to create a pidfile containing the process number. The thing is that monit checks that the file exist... That works fine... But when I kill the process manually... leaving the pidfile, monit doesn't see this... And the process doesn't restart. The process is flashplayer... running an swf in full screen.

It would seem MySQL and VSFTP no longer create pid files and monit requires a pid file to work. Is there any way to force MySQLD and VSFTPD to use pid files or am I out of luck?
View 3 Replies View RelatedI was trying to configure monit for my system.These all are the commands i used to configure:
1). set httpd port to 2812 it worked..
2). ssl enable it gives command not found...
i am unable to locate the problem.....
I have a perl program that I need to an eye on so it run 24/7 and restarts if it stops at any time. I have Webmin installed and I am looking into Mon but it seems it only monitors services like "httpd" and "smtp" rather than a file.pl file which runs. Actually the file creates a pid.log in /var/log/ which has the PID number in it.
Since Monit doesn't come on webmin I am not sure what I need to put in it's config file to monitor my file.pl.
I'm trying to set up and run Monit to monitor an Apache2 webserver, I want to be able to ensure Apache is running and if it's not have it restarted with an email alert sent out.
The monitrc (edited for relevance) looks like:
Code:
check system *server name*
if loadavg (1min) > 4 then alert
if loadavg (5min) > 2 then alert

I've run into a strange problem on one of the servers I maintain. It's running CentOS 5, fully up to date. The server has Monit installed via RPMforge, and runs Postfix as its MTA. Every day at about 4:20am, when cron is running, Monit loses its connection to Postfix. As far as I can tell, nothing is actually going wrong with Postfix and it's always restarted just fine. I run a couple of Debian servers with very similar setups, and the problem does not occur on them.
Perhaps related, other daemons on the CentOS box often lose their pid files at the time when cron runs, which results in Monit thinking they're not running. One service in particular (zarafa-dagent) is so bad for this that I've had to completely disable monitoring of it in Monit. Again, this problem doesn't occur on the Debian boxes I maintain.The problem isn't hugely urgent as everything still runs fine, but it does mean that pretty much every day I get false positive mail alerts from Monit, which is (a) annoying and (b) makes me more likely to miss a real alert.
I've some file with .sh extensions that runs some softwares.Now,how do I stop running that filesI know we run the command ./start_tomcat.sh to start the apache.Is there any command to stop that file/process or is it just kill the process to stop the process

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.

Is it possible to save the process and log out then log in and continue the process? I know how to pause a process using kill -pause pID and continue it using kill -cont pID. But that only work if you don't log out after pausing it.

I want to kill parent process after "fork()" method. but if I kill parent process with "exit(0)" method, main() thread is terminated as well so child prosess doesn't work anymore. Is there any way to kill only parent process without affecting to child process?
#include <sys/types.h>

[code]....
Consider the following code:
Code:
int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)
[code]....
I get the following output:
Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1
[code]....
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?
I need a command to get the process name by process id.

View 2 Replies View RelatedI recenlty set up a headless linux home server by my router will my spare computer parts. I have NFS and even a COD4 server running on it for my friends and me. Because the box is headless, I take controll over it with ssh and start the COD4 server from there, but the problem is, if I close the terminal I have the ssh running from, it closes my server, meaning my desktop needs to be up and running the entire time. That kinda ruins the point of my server
So my question is, is there a way for me to run the command so that it will not close with the terminal AND that I can still send commands to the server.

and I didn't use anything else and didn't install any P2P client in Ubuntu. And then a few day later, my laboratory received the message that someone in our laboratory used P2P with prohibited in the university. The people in my laboratory pointed to me because they're all using windows only me using Ubuntu. So I would like to ask "Is it possible that Ubuntu using P2P in its background? or apt-get or synaptics using P2P in their process?" If Ubuntu can't do that, I can prove myself. But If Ubuntu does, I still can show to them that it's Ubuntu's program and it's legal.
