To aid in monitoring and troubleshooting FRS, maintain a clear
picture of your environment. A common approach is to create a Visio
diagram that describes the replica set configuration. Include the
following information in your diagram:
Replica members and their locations
Bandwidth between servers and sites
Replication topology
Master, hub, and spoke servers
Available disk space on members
How much data is in the replica set
How much data gets changed and how often (and therefore
replicated on a daily basis)
