The Cluster Manager is responsible for node and cluster management. Every node within a Couchbase cluster includes the Cluster Manager component.

The Cluster Manager is responsible for the following within a cluster:

• Cluster management

• Node administration

• Node monitoring

• Statistics gathering and aggregation

• Run-time logging

• Multi-tenancy

• Security for administrative and client access

• Client proxy service to redirect requests

Access to the Cluster Manager is provided through the administration interface on a dedicated network port and through dedicated network ports for client access. Additional ports are configured for inter-node communication.
