install mysql check in monit

[Maravelias Marios - Tophost Internal]

Hello, I have monit running for check and monitoring http.
It works fine.
To day I tried to install monitor for mysql database too.
I added these lines at /etc/monitrc file:

check process mysqld with pidfile /var/run/mysqld/mysqld.pid
        group mysql
        start "/etc/init.d/mysqld start"
        stop  "/etc/init.d/mysqld stop"
        if failed port 3306 then restart
        if 5 restarts within 5 cycles then timeout

in the web interface I see this:

Process

Status

Uptime

CPU

Memory

mysqld

Connection failed

37m

3.4%

5.8% [122288 kB]

Why do I get connection failed? how do I fix that?

Thank you.
