== HTTP Endpoint
experimental[]
{beatname_uc} can expose internal metrics through an HTTP endpoint. These are useful to
monitor the internal state of the Beat. For security reasons the endpoint is disabled
by default, as you may want to avoid exposing this info.
The HTTP endpoint has the following configuration settings:
`http.enabled`:: (Optional) Enable the HTTP endpoint. Default is `false`.
`http.host`:: (Optional) Bind to this hostname or IP address.
It is recommended to use only localhost. Default is `localhost`
`http.port`:: (Optional) Port on which the HTTP endpoint will bind. Default is `5066`.
This is the list of paths you can access. For pretty JSON output append ?pretty to the URL.
