Adding new parameter for web server base path

[jesjimher]

It would be nice if a parameter existed to specify a web context for glances when it's running as a web server (-w), so that listening URL would be http://localhost:port/context. Something like:

$ glances -w --web-base-path myglances
Glances web server started on http://0.0.0.0:61208/myglances/

It would make Apache or Nginx configuration much easier when glances must be executed behind a proxy. Right now it's possible to make it work, but it's pretty tricky and doesn't work for everyone.

Thanks a lot for the great work, glances is great!

@notFloran : What is the impact of such enhancement in the Web UI code ?

[notFloran]

@nicolargo I don't know, I will try to make a POC and see if that broke something

[notFloran]

@nicolargo We need to update the wiki https://github.com/nicolargo/glances/wiki/Reverse-proxy-to-the-Glances-Web-UI

Since the 2.11 :

location / {
  if ($http_referer ~ "^https?://[^/]+/glances"){
    rewrite ^/(.*) /glances/$1 redirect;
  }
}

and

location / {
        if ($http_referer ~ "^https?://[^/]+/glances"){
                rewrite ^/(.*) https://$http_host/glances/$1 redirect;
        }
}

are useless

Done ! Can you have a look on the Wiki and check that the configuration is fine ?

[notFloran]

For the issue I see the following problem:

• with a web-base-path argument all routes of bottle (webui and API) will be prefixed
• in the 3.0 roadmap I see that client/server mode will use the REST API

So we can have the following setup:

• server 1:
  • no web-base-path-> API available at IP:61208/api
• server 2:
  • web-base-path on -> API available at IP:61208/my-base-web-path/api

Currently to connect to the server we execute : glances -c <ip>.

With the new web-base-path we need something like glances -c <ip> --web-base-path <web_base_path> or glances -c <url_of_the_api>

nginx config is ok, for apache I have not tested but it seems ok

@notFloran completely agree with your last comment. Concerning the Glances 3.0 roadmap, i am not sure that the Restful API will replace the XML/RPC. The bandwidth consumption between a server and a client is *10 between the RPC and the Restful. Before switching, i have to find a way to optimize and reduce the bitrate.
