Top Forums Shell Programming and Scripting script to grep outofmemory message in logs Post 302477695 by coolguyamy on Monday 6th of December 2010 07:58:21 AM

Hello Jim,

Thanks for the response. My requirement is the script should check all variables i.e var1,var2,var3,var4,var5 and var6. If var1 contains "outofmemory" message then it should send message there is an outofmemory error on tomcat1 same for other variables like var2,var3,var4,var5,var6. If var2 contains outofmemory then it should send there is an outofmemory for tomcat2. Please guide me to implement this logic.

Also can you please explain me how can we use below command to grep for outofmemory message.Please let me know what should we keep in place of *(tomcat*logs).

var=$(grep -l 'outofmemory' tomcat*logs)
if [ ! -z "$var" ] ; then
echo "outofmemory error in file(s) $var" | mailx -s 'outofmemory error' me@myaddress.com
fi

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
