With the upgrade to Elasticsearch 5.x and 6.x, plugins are deprecated. It's suggested to use [[Kibana]] as a monitoring and management interface to Elasticsearch.

You'll need to set xpack.monitoring.collection.enabled=true for Elasticsearch to do self-monitoring. If that is enabled in your elasticsearch.yml, then you can navigate in the left-panel of Kibana to "Stack Monitoring" under the "Management" section at the bottom. However that is called 'internal monitoring'. It has long been recommended to use a distinct 'external' service called '''Metricbeat''' for monitoring the health of your Elasticsearch cluster.
