HTTP Endpoint

HTTP Endpoint

edit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

Journalbeat 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.

Info

edit

/ provides basic info from the Journalbeat. Example:

curl -XGET 'localhost:5066/?pretty'

{
  "beat": "metricbeat",
  "hostname": "example.lan",
  "name": "example.lan",
  "uuid": "34f6c6e1-45a8-4b12-9125-11b3e6e89866",
  "version": "6.5.4"
}

Stats

edit

/stats reports internal metrics. Example:

curl -XGET 'localhost:5066/stats?pretty'
