I know it might seem to be a sledgehammer to crack a nut, but Nagios is a good service oriented monitoring tool that is OSS.
BTW Most load-balancing devices that need to do service monitoring simply open the service port and try to get a basic response that proves that the service is up and operating. For instance for a web service with a DB backend you might first do a simple HTTP GET of a static page (and compare with a known result) and then do a simple DB query via the web service to make sure the DB is running. Clearly some sort of algorithm needs to be determined of when to declare a service "down" (and when to declare it available again). (Of course if you want a slightly bigger sledgehammer there is HP OpenView....
