Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to a host. It can also protect hosts from security threats, query data from operating systems, forward data from remote services or hardware, and more. Refer to the documentation for a detailed comparison of Beats and Elastic Agent.

The Nats module uses Nats monitoring server APIs to collect metrics.

The default metricsets are stats, connections, routes and subscriptions while connection and route metricsets can be enabled to collect detailed metrics per connection/route.
