Sysadmin Script to enable/disable CloudFlare DDoS protection automatically

I just follow this guide: Script to enable/disable CloudFlare DDoS protection automatically – VPSAddicted

/etc/ddos/attack.sh files works as expected, but:
Script
/etc/ddos/ddos.sh doesn't work.

What's wrong with the code?
I even change this line:
grep -w "[0.00-0.05]" $FILE >/dev/null
To be sure I capture the average load.

But it does nothing.
Please bash scripting guru .

I found much better implementation now
Create server load monitoring bash script - InMotion Hosting

 

My script is much simpler now:

Code:

#!/bin/bash
trigger=6.00

load=`cat /proc/loadavg | awk '{print $1}'`
response=`echo | awk -v T=$trigger -v L=$load 'BEGIN{if ( L > T){ print "greater"}}'`
if [[ $response = "greater" ]]
then
sar -q | mail -s"High load on server - [ $load ]" me@gmail.com
/usr/bin/sh /etc/ddos/attack.sh
else
/usr/bin/sh /etc/ddos/noattack.sh
fi

 

Your backup script and centminmod nginx/php recompile only consume 100-200% of my total Intel i7 8 core /800% Server .

 

This is so true:

I experienced it the last 2 days.
Even if I'm on Cloudflare Pro plan.

Luckily OVH can combat Layer 7 attacks also.
Which is really great.
