Running

Before application can be run an authentication token is needed from plex.tv. This can be acquired by running plex_exporter token.

Plex exporter can then be run with plex_exporter -t <auth_token> --auto-discover and Plex servers will be auto discovered from plex.tv (this will only include servers you own).

Without auto discovery

If you don't want to auto discover from plex.tv you can provide a base url to the server with --plex-server.

Config file

--plex-server flag only supports specifying a single Plex server. If you want to provide more you need to use the config file.

address: ":9594"
logLevel: "info"
logFormat: "text"
autoDiscover: false
token: "asdf1234"
servers:
- baseUrl: https://my.plexserver.io:32400
  insecure: true
# My friend trusts me a lot
- baseUrl: https://myfriends.plexserver.io:32400
  token: my-friends-token

Servers without a token use the token from top-level config.

The insecure key turns off tls verify for that server.
