check_proc_mem.sh: check process memory usage

First of all, thanks your work! As I see if you use --cmdpattern, the script counts only the first process' mem usage. So if you run httpd or other services with fork/child calculate with it. I prefer to send back the warning and critical in perform data. So I modified the script a bit. if [ "$memVmRSS" -ge "$4" ]; then echo "Memory: CRITICAL VIRT: $memVmSize MB - RES: $memVmRSS MB used!|RES=$(($memVmRSS*1024*1024));$(($2*1024*1024));$(($4*1024*1024));;" $(exit 2) elif [ "$memVmRSS" -ge "$2" ]; then echo "Memory: WARNING VIRT: $memVmSize MB - RES: $memVmRSS MB used!|RES=$(($memVmRSS*1024*1024));$(($2*1024*1024));$(($4*1024*1024));;" $(exit 1) else echo "Memory: OK VIRT: $memVmSize MB - RES: $memVmRSS MB used!|RES=$(($memVmRSS*1024*1024));$(($2*1024*1024));$(($4*1024*1024));;" $(exit 0) fi

Hi and thanks for a great plugin. I ran into an issue because I had renamed the file from check_proc_mem.sh to just check_proc_mem as I like them w/ no file extension since that is how they commonly are in the plugin directory. This caused an issue in the grep -v portion. I added some things to accommodate this changes, here is the modified script that will work just in case someone else happens to rename it: #!/bin/bash -e ##------------------------------------------------------------------- ## File: check_proc_mem.sh ## Author : Denny ## Description : ## -- ## ## Link: http://www.dennyzhang.com/nagois_monitor_process_memory ## ## Created : ## Updated: Time-stamp: ##------------------------------------------------------------------- SCRIPTNAME=$(basename $0) if [ "$1" = "-w" ] && [ "$2" -gt "0" ] && [ "$3" = "-c" ] && [ "$4" -gt "0" ]; then pidPattern=${5?"specify how to get pid"} if [ "$pidPattern" = "--pidfile" ]; then pidfile=${6?"pidfile to get pid"} pid=$(cat $pidfile) elif [ "$pidPattern" = "--cmdpattern" ]; then cmdpattern=${6?"command line pattern to find out pid"} pid=$(ps -ef | grep "$cmdpattern" | grep -v grep | grep -v ${SCRIPTNAME} | head -n 1 | awk -F' ' '{print $2}') elif [ "$pidPattern" = "--pid" ]; then pid=${6?"pid"} else echo "ERROR input for pidpattern" exit 2 fi if [ -z "$pid" ]; then echo "ERROR: no related process is found" exit 2 fi memVmSize=`grep 'VmSize:' /proc/$pid/status | awk -F' ' '{print $2}'` memVmSize=$(($memVmSize/1024)) memVmRSS=`grep 'VmRSS:' /proc/$pid/status | awk -F' ' '{print $2}'` memVmRSS=$(($memVmRSS/1024)) if [ "$memVmRSS" -ge "$4" ]; then echo "Memory: CRITICAL VIRT: $memVmSize MB - RES: $memVmRSS MB used!|RES=$(($memVmRSS*1024*1024));;;;" $(exit 2) elif [ "$memVmRSS" -ge "$2" ]; then echo "Memory: WARNING VIRT: $memVmSize MB - RES: $memVmRSS MB used!|RES=$(($memVmRSS*1024*1024));;;;" $(exit 1) else echo "Memory: OK VIRT: $memVmSize MB - RES: $memVmRSS MB used!|RES=$(($memVmRSS*1024*1024));;;;" $(exit 0) fi else echo "${SCRIPTNAME}" echo "" echo "Usage:" echo "${SCRIPTNAME} -w -c " echo "" echo "Below: If tomcat use more than 1024MB resident memory, send warning" echo "${SCRIPTNAME} -w 1024 -c 2048 --pidfile /var/run/tomcat7.pid" echo "${SCRIPTNAME} -w 1024 -c 2048 --pid 11325" echo "${SCRIPTNAME} -w 1024 -c 2048 --cmdpattern "tomcat7.*java.*Dcom"" echo "" echo "Copyright (C) 2014 DennyZhang (denny.zhang001@gmail.com)" exit fi ## File - check_proc_mem.sh ends
