List and Status of Clusters

The available clusters and cluster nodes can be listed under the Command Line Interface, and their statuses inspected, with the exaclusters and exanodes commands respectively.

List Clusters

An example of output of the exaclusters command allowing to list available clusters is shown below.

>>> exaclusters
ALIAS        HOSTNAME

cluster-001  master-production-20160630cluster-001.exabyte.io
cluster-007  master-production-20160630cluster-007.exabyte.io

List Cluster Nodes

An example of the output of the other exanodes command allowing to list available cluster nodes is included below.
