Elasticsearch node_stats metricset

The node_stats metricset interrogates the Cluster API endpoint of Elasticsearch to get the cluster nodes statistics. The data received is only for the local node so this Metricbeat has to be run on each Elasticsearch node.

The indices stats are node-specific. That means for example the total number of docs reported by all nodes together is not the total number of documents in all indices as there can also be replicas.

Fields

For a description of each field in the metricset, see the exported fields section.
