We would like to monitor few servers,like if the server goes down i
should get a pop-up instantly without fail. I know it is possible,
but i have no idea on how to setup it. It will be so kind if someone helps
me to setup it. Thanks in advance..

You can use ping. Although ping failure doesn't necessarily mean that your system is down, it can also happen if the network is down but I believe for most intents and purposes these are same thing. You can use following script



#!/bin/bash
HOSTS="cyberciti.biz theos.in router"

COUNT=4

for myHost in $HOSTS
do
count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')
if [ $count -eq 0 ]; then
# 100% failed
echo "Host : $myHost is down (ping failed) at $(date)"
fi
done


This is from here. You can also setup a cron job for this or any similar script to ping all your servers after a regular interval.
