To learn about monitoring in general, see Monitoring the Elastic Stack.
1. Configure your cluster to collect monitoring data:
a. Verify that the xpack.monitoring.enabled setting is true, which is its default value, on each node in the cluster. For more information, see Monitoring settings.
b. Verify that the xpack.monitoring.elasticsearch.collection.enabled setting is true, which is its default value, on each node in the cluster.
There is something like xpack which is installed during elasticsearch installation. In Bitnami xpack doesn't exist. So, how can I enable monitoring?
