Software :: Monitor Mysql 5.0.77 With Nagios 3.2.1 Under CentOS 5.4?

Trying to monitor mysql 5.0.77 with nagios 3.2.1 under CentOS 5.4. Everything with nagios has been running without a hitch for me, however, when I added the following to /etc/nagios/objects/localhost.cfg to try to monitor mysql, I get an error that reads "Running configuration check... CONFIG ERROR! Restart aborted. Check your Nagios configuration."

define service{
use local-service
host_name localhost
service_description MYSQL
check_command check_mysql
notifications_enabled 1
}

This is pretty much what I added to monitor other things on the server such as ftp and smtp, just switched out check_smtp with check_mysql, etc.
