title: nrpe: command mysql_check not defined
body: <p>I'm trying to check mysql and tomcat on localhost.
  Basically I need to check the ports to see the applications are listening.
  I have nrpe and nagios plugins installed
  I'm trying to use nrpe to check mysql on localhost, but nagios shows this error: NRPE: command check_mysql not defined</p>
  
  <p>Any idea please?</p>
