Following tools are available for replication check:
1. Basic monitoring script, which allows to see what is going on with replication at this very moment. It does not send any notifications and cannot be thought as complete solution to replication monitoring. Mature tools (like Nagios) should be used in near future.
2. Server-side replication check made by M.DePhillips. This script checks which slaves are connected to master (robinson) on daily basic. List of connected slaves is compared to the known slave list (stored at dbAdmin database at heston.star.bnl.gov).
