Agent uses a HTTP check if the service listen on port 9200.

If some auto-detected parameters are wrong, you can manually override them by adding the following to /etc/glouton/conf.d/99-local.conf:

service:
  [...]

  # For an Elasticsearch running outside a container
  - type: "elasticsearch"
    address: "127.0.0.1"
    port: 9200

  # For an additional Elasticsearch running outside a container
  - type: "elasticsearch"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 9201

  # For an Elasticsearch running in a Docker container
  - type: "elasticsearch"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 9200
