Redis cache monitoring / Automating telnet session using bash scripts

Below is a combination of shell & expect script which helps to monitor Redis cache.

Get your shell script [redistest.sh] embedded in Nagios/Zenoss [ or whichever monitoring tool you are using ] to set up monitoring for redis cache.

redistest.sh #!/bin/bash set -x var=`/tmp/redistest| awk '{print $1}'|grep PONG|cut -c2-5` echo $var if [ "$var"  == "PONG" ] then echo "Redis is now running fine |" exit 0 else echo "Redis is having some issue |" exit 2 fi echo "Unknown error|" exit 3

redistest #!/usr/bin/expect set timeout 5 set serverip "10.50.16.10" set port 6379 spawn telnet $serverip $port send "ping\r" expect "+PONG" exit
