X-Pack monitoring in Kibana serves two separate purposes:
- To visualize monitoring data from across the Elastic Stack. You can view health and performance data for Elasticsearch, Logstash, and Beats in real time, as well as analyze past performance. For more information, see Monitoring the Elastic Stack.
- To monitor Kibana itself and route that data to the monitoring cluster.
If you enable X-Pack monitoring across the Elastic Stack, a monitoring agent runs on
each Elasticsearch node, Logstash node, Kibana instance, and Beat to collect and index
metrics. Each node and instance is considered unique based on its persistent
UUID, which is written to the
path.data directory when the node
or instance starts.
