nagios_context | string

Default: juju

This address is used by the Web Interface to download secondary assets (JavaScript/CSS/etc). This setting should be the public address of the proxy, which will direct traffic to Graylog. For Graylog 2, the proxy should connect back to the address set in 'web_listen_uri' *. The 'web_listen_uri' will be used as the default value if this config is left blank.
