This HOW-TO is realized to monitor a group of processes on linux machine.
1) create a check_process.sh like this:
#!/bin/bash
#
# Uso: .//check_system_pp
#
##################################################################################
#
# Processi da analizzare
PROCLIST_RED="init syslogd collectd"
##################################################################################
PATH="/usr/bin:/usr/sbin:/bin:/sbin"
STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKNOWN=3
STATE_DEPENDENT=4
check_processes_red()
{
PROCESS="0"
ERROR_PROCS=""
for PROC in `echo $PROCLIST_RED`; do
if [ `ps -ef | grep $PROC | grep -v grep | wc -l` -lt 1 ]; then
PROCESS=1
ERROR_PROCS="$ERROR_PROCS""$PROC ";
fi
done
if [ $PROCESS -eq "1" ]; then
exit_red=$STATE_CRITICAL
elif [ $PROCESS -eq "0" ]; then
exit_red=$STATE_OK
fi
}
check_processes_red
final_exit=`expr $exit_red`
if [ $final_exit -eq "0" ]; then
echo "SYSTEM OK - All monitored resources OK. Processes: $PROCLIST_RED"
exitstatus=$STATE_OK
elif [ $final_exit -eq "1" ]; then
echo "SYSTEM WARNING - Processes DOWN. ($WARNING_PROCS)."
exitstatus=$STATE_WARNING
elif [ $final_exit -ge "1" ]; then
echo "SYSTEM CRITICAL - Resources DOWN! Processes: $ERROR_PROCS
$WARNING_PROCS"
exitstatus=$STATE_CRITICAL
fi
exit $exitstatus
This is a NAGIOS plugin, modified to fit the zenoss structure.
2) modify the list of processes to monitor, and move the file into /usr/bin
with the maximum privileges
3) follow this guide to import a NAGIOS plugin into Zenoss
http://www.zenoss.com/community/docs/howtos/create-modify-nagios-templates
but remember to set the ZENOSS command path to /usr/bin (generally is
/opt/libexec or something..)
4) we've done!!!
