Each Elasticsearch node, Logstash node, Kibana instance, and Beat instance is considered
unique in the cluster based on its persistent UUID, which is written to the
path.data directory when the node or instance starts.
Monitoring documents are just ordinary JSON documents built by monitoring each Elastic Stack component at a specified collection interval. If you want to alter the templates for these indices, see Configuring indices for monitoring.
Metricbeat is used to collect monitoring data and to ship it directly to the monitoring cluster.
To learn how to collect monitoring data, see:
