向我发送电子邮件并重新启动tomcat攻击DDOS的脚本

Question

I need help to have a script to send me an e-mail alert when system resource intensive CPU and memory. I would also be interested in a script that when the tomcat is reaching the limits of its resources reboot my pc (This script would be to prevent DDOS attacks).

I wish you could help me !! Thank you

SOLUTION!!!!

Here is the script of which I spoke. This script will automatically restart the Tomcat when it exceeds 95% of physical memory. Enjoy it !!

porcentaje=95

usoMemoria=$(ps aux | grep tomcat | grep -v grep | awk '{printf ("%.0f", $4)}')

if [ $usoMemoria -ge $porcentaje ]; then

echo "Se ha superado el tope (95%) de memoria que se ha establecido para el Tomcat. Se procede a su reinicio automatico"

echo "$(date)"

echo "Comenzando..."

service tomcat7 restart

echo "Terminando Script..."

fi

exit 0
