No monitoring data is visible in Kibana

edit

Symptoms: There is no information about your cluster on the Stack Monitoring page in Kibana.

Resolution: Check whether the appropriate indices exist on the monitoring cluster. For example, use the cat indices command to verify that there is a .monitoring-kibana* index for your Kibana monitoring data and a .monitoring-es* index for your Elasticsearch monitoring data. If you are collecting monitoring data by using Metricbeat the indices have -mb in their names. If the indices do not exist, review your configuration. For example, see Monitoring in a production environment.

Monitoring data for some Elastic Stack nodes or instances is missing from Kibana

edit

Symptoms: The Stack Monitoring page in Kibana does not show information for some nodes or instances in your cluster.

Resolution: Verify that the missing items have unique UUIDs. Each Elasticsearch node, Logstash node, Kibana instance, Beat instance, and APM Server is considered unique based on its persistent UUID, which is found in its path.data directory. Alternatively, you can find the UUIDs in the product logs at startup.

In some cases, you can also retrieve this information via APIs:

For Beat instances, use the HTTP endpoint to retrieve the uuid property. For example, refer to Configure an HTTP endpoint for Filebeat metrics.
For Kibana instances, use the status endpoint to retrieve the uuid property.
For Logstash nodes, use the monitoring APIs root resource to retrieve the id property.

When you install Elasticsearch, Logstash, Kibana, APM Server, or Beats, their path.data directory should be non-existent or empty; do not copy this directory from other installations.
