Connections check shell script

Monday, June 4th, 2007

You only have to fill this: {mysq_ladmin_pass} with your mysql administrator password.

#!/bin/sh

pass={mysq_ladmin_pass}

echo “Apache Connections (port 80):” `netstat -an |grep :80 |wc -l`
echo “MySQL Connections (port 3306):” `mysqladmin -uadmin -p”$pass” processlist |wc -l`
echo “SMTP Connections (port 25):” `netstat -an |grep :25 |wc -l`
