sorry for not explaining my problem properly.As you suggested I read all the graylog docs but I didn’t find any solution to my problem.
I configured my graylog through nginx to access with the http://:/graylog/.
Bu using the above configuration I am able to get the web interface of graylog with /graylog context.
It is working fine for the options like search,streams,dashboards,alerts.sources it is working very well.BUt for the options under the system like inputs and outputs it is framing the url as http://:/graylog/graylog/system/xxxx.

my graylog and nginx is running in the docker containers

first check X-Graylog-Server-URL property…

I just pasted the X-Graylog-Server-URL property above.if you find anything wrong,please let me know.

as I see, you missed the doc in this topic.
http://docs.graylog.org/en/3.0/pages/configuration/web_interface.html

I would like to highlight this part

How does the web interface connect to the Graylog server?

The web interface is fetching all information it is showing from the REST API of the Graylog server. Therefore it needs to connect to it using HTTP(S). There are several ways how you can define which way the web interface connects to the Graylog server. The URI used by the web interface is determined in this exact order:

  • If the HTTP(S) client going to the web interface port sends a X-Graylog-Server-URL header, which contains a valid URL, then this is overriding everything else.
  • If http_external_uri is defined in the Graylog configuration file, this is used if the aforementioned header is not set.
  • If http_publish_uri is defined in the Graylog configuration file, this is used if the aforementioned http_external_uri is not set.
  • If none of the above are defined, http://$http_bind_address is used.

The web interface assets (e.g. the index.html , CSS and JavaScript files) are accessible at the URI root ( / by default) and the REST API endpoints are accessible at the /api path.

There is also an example config. It’s different from yours.

I’m experiencing the same thing. Installed 3.0 according to docs. All works fine when accessing it directly on my server via port 9000.
I want to access my GL instance through my Nginx proxy on another server.
So http://srvA.domain.it:9000 works perfect. All menu items resolve. API browser works.

After reading the docs I’ve setup my Nginx so I can access my GL like https://domain.it/gl (Nginx hosted on srvB). Every item in the menu works, execpt when accessing something under System it wants to go to https://domain.it/gl/gl/system/inputs (mark the double gl!).

My nginx entry:

   # Slash graylog 
location /gl/ {
    proxy_set_header    Host                    $http_host;
    proxy_set_header    X-Forwarded-Host        $host;
    proxy_set_header    X-Forwarded-Server      $host;
    proxy_set_header    X-Forwarded-For         $proxy_add_x_forwarded_for;
    proxy_set_header    X-Graylog-Server-URL    https://$server_name/gl;
    rewrite             ^/gl/(.*)$  /$1  break;
    proxy_pass	        http://srvA.domain.it:9000;
}

I tried already various configs suggested on this board. What’s weird is that all works great exept those item menus under System. So when removing one ‘/gl’ ( https://domain.it/gl/system/inputs) it works!!

I think your not getting the problem what I am saying exactly,The above docs saying that will work with / context.For me its working as per the above docs.
In my case graylog wants to work with /graylog context,for this I changed the config and I clearly described the problem currently I am facing with /graylog context.

Don’t say again to check the documents,My requirement is graylog has to work with /graylog context not with / context.

thanks

Hi ,

Exactly I am also facing the same issue ,why it is appending the context again for the url for the options under the system.

10

have you been able to solve this issue?

I created an issue for that in github because I was able to verify the issue
