At the moment you can only test mysql using checktype=connect
or by setting service=none. The latter would be the default
in this case as you are using port 3306 which is
not associated with a service that ldirectord knows about.
To use the request and receive directives, which would
presumably be an sql query of some sort and an expected response,
you would need to add mysql support to ldirectord.
This should be quite simple as I believe mysql has perl bindins.
Take a look inside ldirectord for check_http and others for
an idea of how this should work.
