The web admin UI

Now, let's understand and explore the main administrative web user interface provided for managing Couchbase clusters. It provides a complete interface for configuring, managing, and monitoring Couchbase clusters.

Some of the main functionalities it provides are as follows:

• The administrator can view the overall health of the Couchbase cluster
• The administrator can create data buckets, perform configuration, and modify various properties related to buckets
• The administrator can view active nodes, their configuration, and perform overall operations in the cluster

The web UI provides various tabs that can be used to view cluster information, details of the server nodes, information about data buckets, view configuration, the configuration options for XDCR (for data replication), logging and setting of the cluster name, and so on.

The Cluster Overview section provides an overview of the Couchbase cluster status. It's the home page of the web console. The administrator can take a glance at the overall status of the cluster from a single window:

The Cluster section provides information about the RAM and disk usage for the cluster. As shown in the preceding screenshot, out of an overall cluster with a total memory size of 2 GB RAM, approximately 1.09 GB is allocated to the default bucket. The total memory/cache size of the cluster is 2 GB, since we have configured a 2 GB RAM quota for each server contributing to the cluster at the time of installation. Currently, we have only one node in our cluster.

The total cluster disk size is the total space of the drive in which the Couchbase node is being installed. In our case, we have installed it in the C: drive and its capacity is 195 GB. Out of this, 146 GB is free, as shown here:
