# check_procl.sh,v 1.1 2002/07/04 09:35
#
# Description :
#
# This plugin is for check the %cpu, %mem or cputime of one or more process
#
# Usage :
#
# check_procl.sh -p process1,process2,... -w a.b -c c.d --cpu
# check_procl.sh -p process1,process2,... -w a.b -c c.d --mem
# check_procl.sh -p process1,process2,... -w a:b:c -c d:e:f --cputime
#
# check_procl.sh -p %all% -e process1,process2,... -w <a.b | a:b:c> -c <c.d | d:e:f> <--cpu | --mem | --cputime>
# check_procl.sh -p %max% -e process1,process2,... -w <a.b | a:b:c> -c <c.d | d:e:f> <--cpu | --mem | --cputime>
#
# Example :
#
# To know the memory eaten by HTTPD processes, be warned when it reach 50% and be critical when it reach 75%
# check_procl.sh -p httpd -w 50.0 -c 75.0 --mem
# > OK - total %MEM for process httpd : 46.1
#
# To know the process which eat the more cpu time, but as we are under linux and are using kapm we do :
# check_procl.sh -p %max% -e kapmd-idle,kapmd -w 0:1:0 -c 0:2:0 --cputime
# > CRITICAL - total CPUTIME for process named : 02:32:10
#
# Tested on solaris 7/8, Linux Redhat 7.3 and Linux Suse 7.1
#
# BUGS : problems with handling time on solaris...
