Elasticsearch Health Status widget

The Elasticsearch Health Status widget provides information about overall health of the Elastic Search cluster. It includes this information:

• Cluster Status

  The cluster status is displayed as green, yellow or red:

  • Green indicates that the cluster is healthy, all indexes and shard allocations are available, and no actions are required.
  • Yellow indicates that the cluster is functional but that some of the indexes for which the primary shards are allocated have replicas that are not allocated.
  • Red indicates that there are one or more unassigned shards in the cluster.
• Total Number of Nodes

  The total number of nodes that is part of the cluster at any given point in time is shown. If the number of nodes is fewer than the number of nodes configured, corrective actions must be taken to make sure the node is available.

• Total Number of Primary and Replica Shards

  The total number of primary and replica shards on the cluster is shown. This information is important to monitor as an excessive number of shards can cause a cluster to be unstable.

• Total Storage Space Used

  This is the total storage space for the cluster.

• Total Indexes

  This is the total number of indexes available in the cluster.
