Is there a way to poll for a service on multiple servers? I understand the concept of the Host and a service that is being polled for. But I would like to be able to do 1 service on multiple servers. So as long as the service is up on one server it will show as being up.

Check out the check_cluster plugin.

There's also BPI which can be used to group services. You would set up both master and slave checks and group them into a BPI group. From there you can check the health of the group using check_bpi.php and send notifications based on the health.

You'll still need to setup host and service checks, but the above options let you group them and get alerts based on the cluster status instead of individual checks.
