I implemented a monitor for a clustered MySQL service. Wrote it up at http://leapfrog.motd.org/2008/02/26/monitoring-mysql-and-redhat-cluster/ As it implies, it's specific to monitoring MySQL but the methodology could be applied to any service (as long as something returns host-specific information.)
