Clusters

The Clusters page provides a table summarizing all Kafka clusters for which interceptors are collecting monitoring data:

There are four columns:

Cluster name

A human friendly name for the cluster (by default, the cluster GUID). This name is specified using the Cluster Edit page in Control Center and is not exposed outside of Control Center.

ZooKeeper servers

A list of ZooKeeper servers configured for the cluster. This information is only available if the cluster is the same as the one being used internally by Control Center. This column will be blank for other clusters.

Bootstrap servers

A list of bootstrap servers configured for the cluster. This information is only available if the cluster is the same as the one being used internally by Control Center. This column will be blank for other clusters.

GUID

A unique id associated with the Kafka cluster (provided by the cluster). This information is available for all clusters running Kafka version 0.10.1.0 or higher.

Setting a Cluster Name

To set a human friendly name for a cluster, click the elipsis icon to the right of the Cluster name column on the row associated with the cluster:

Specify the Cluster name in the Edit cluster page, and press Save cluster. By default the Cluster name is the GUID provided by the cluster.
