Going forward, the plan is for stack products to be monitored with Metricbeat instead of the products internally monitoring themselves. So far this plan has been implemented for Elasticsearch and Kibana.

For Elasticsearch, see https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-metricbeat.html. Note that this page is linked to from https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-monitoring.html and https://www.elastic.co/guide/en/elasticsearch/reference/current/collecting-monitoring-data.html.

For Kibana, see https://www.elastic.co/guide/en/kibana/current/monitoring-metricbeat.html. Note that this page is linked to from https://www.elastic.co/guide/en/kibana/current/configuring-monitoring.html and https://www.elastic.co/guide/en/kibana/current/monitoring-kibana.html.

We will need equivalent documentation pages for each Beat as well, as Metricbeat has gained the ability to monitor Beats starting 7.3.0.
