Before you install Centrify Audit & Monitoring Service, you should develop a basic deployment plan for how you will distribute and manage the components that make up an installation. For example, you should decide how many collectors and audit stores to create and where to put them. You should also consider the network connections required and how many computers you plan to audit. For example, you can have multiple agents using the same set of collectors, but you should keep the collectors within one hop of the agents they serve and within one hop of the audit stores to which they transfer data.
By planning where to install components initially, you can determine the number of collectors you should have for load balancing or redundancy. After the initial deployment, you can add collectors and audit stores whenever and wherever they are needed.
