The network interface used by the Graylog HTTP interface.
This network interface must be accessible by all Graylog nodes in the cluster and by all clients using the Graylog web interface.
http_publish_uri = http://$http_bind_address/
The HTTP URI of this Graylog node which is used to communicate with the other Graylog nodes in the cluster and by all clients using the Graylog web interface.
The URI will be published in the cluster discovery APIs, so that other Graylog nodes will be able to find and connect to this Graylog node.
This configuration setting has to be used if this Graylog node is available on another network interface than $http_bind_address, for example if the machine has multiple network interfaces or is behind a NAT gateway.
This configuration setting must not be configured to a wildcard address!
http_external_uri = $http_publish_uri
The public URI of Graylog which will be used by the Graylog web interface to communicate with the Graylog REST API.
The external Graylog URI usually has to be specified, if Graylog is running behind a reverse proxy or load-balancer and it will be used to generate URLs addressing entities in the Graylog REST API (see $http_bind_address).
When using Graylog Collector, this URI will be used to receive heartbeat messages and must be accessible for all collectors.
This setting can be overriden on a per-request basis with the “X-Graylog-Server-URL” HTTP request header.
