Tip: Script for Checking for Server Load

Rai    Linux     bash, email, Linux, script, server, shell

I wrote this simple bash script so I could tell the server’s current load by email. The script is run every 15 minutes and very lightweight.

#!/bin/bash

LOAD=`uptime | awk -F: ‘{print $5}’ | awk -F\, ‘{print $1}’`
RCPT=”kamotegirl@pinoytux.com”
TIMESTAMP=`date +%D\ %T\ %Z`

`uptime|mail -s “Server Load as of $TIMESTAMP is $LOAD” $RCPT`

Then setup the cronjob to execute the script to run every 15 minutes and send an email to the RCPT.
