Cron job for monitoring processes

Shell Programming and Scripting
1

I have to monitor several processes in my application .

i get the listing of these processes using the command ps -ax

i want to write a shell script that will monitor the processes and if a

process goes missing then it will send an email to my gmail account.

I want to run this script as a cron job that will start every 15min.

kindly provide me with the shell script and the directory in the server

where this shell script needs to be placed and the cron entry for running

this script every 15min. I need all this information as i am new to unix

and i have to implement this stuff on my server as soon as poosible.

Please any one help me!!!!!(my OS is Solaris 5.6)

man crontab

I know how cron works. But i haven't made any changes to it as of now.The basic problem is , how my cron job will monitor the process and send an email when the process goes missisng

First, as to your private message, google "linux command line email" and look at the first link.

To this question, what have you tried? You mentioned ps output, you'll have to do something with that output to get what you want. From what I've seen, most folks on here are happy to help with specific problems but have other jobs to do.

An answer to the question "this script is having problems and I need some help" will have a much different answer than "these are the requirements I have, please write the script for me".

grep "CMIS_STACK_LAN" processlist.txt

if [ $? -ne 0 ]
then
CMIS_STACK_LAN & (this is used to restart the CMIS process which is stoped)
date > error.log
echo "the process CMIS has stopped" >> error.log
fi

peterro,

the command CMIS_STACK_LAN & is used to restrt my application process

there are to users in my server

1)root

2)net1

now to run the above command, i will have to be net1 user

so when i run this command manually i have to do the following

su net1

CMIS_STACK_LAN &

now when i do the same thing in a script , the command does not run

the CMIS_STACK_LAN is a C code that runs continuously on the server.

this is so far my progress.

Can any one of the gurus out there help me out with this

Hi Neo,

I have figured that out

before doing

grep 'CMIS_STACK" process.txt,

i will have to do ps -ax > process.txt

thanks for pointing out my mistake.

now my problem is , i have to run the CMIS process if it is missing

i have to run this process from user netmon.

on command prompt ,i have to do the following.

su - netmon
CMIS_STACK &

and the process starts successfully.

but when i include the same things in a shell script , the scripts exits,
without restarting the process.

can you please help me out with the problem

You could run the monitor job as either the netmon user or see if the -c switch is available on your version of su. It allows you to run a single command as another user.
