Statman error after building release with exrm

When I try to start my app after creating a release with exrm, I get the following error:

14:04:51.276 [info] Application discorelic exited: exited in: Discorelic.start(:normal, [])
    ** (EXIT) an exception was raised:
        ** (UndefinedFunctionError) function :statman_server.add_subscriber/1 is undefined (module :statman_server is not available)
            :statman_server.add_subscriber(:statman_aggregator)
            (discorelic) lib/discorelic.ex:26: Discorelic.start/2
            (kernel) application_master.erl:273: :application_master.start_it_old/4
{"Kernel pid terminated",application_controller,"{application_start_failure,discorelic,{bad_return,{{'Elixir.Discorelic',start,[normal,[]]},{'EXIT',{undef,[{statman_server,add_subscriber,[statman_aggregator],[]},{'Elixir.Discorelic',start,2,[{file,\"lib/discorelic.ex\"},{line,26}]},{application_master,start_it_old,4,[{file,\"application_master.erl\"},{line,273}]}]}}}}}"}

This happens on both macOS and CentOS, erlang/OTP 18 and 19, and elixir 1.3.3

If it works outside of exrm, it's likely you're missing an application in your mix.exs.

@blatyo Thanks for the response. I get this error when I try to add statman to my applications list

10:25:59.104 [info] Application statman exited: :statman_app.start(:normal, []) returned an error: shutdown: failed to start child: :statman_server
    ** (EXIT) already started: #PID<0.1313.0>
{"Kernel pid terminated",application_controller,"{application_start_failure,statman,{{shutdown,{failed_to_start_child,statman_server,{already_started,<0.1313.0>}}},{statman_app,start,[normal,[]]}}}"}

Crash dump is being written to: erl_crash.dump...done
Kernel pid terminated (application_controller) ({application_start_failure,statman,{{shutdown,{failed_to_start_child,statman_server,{already_started,<0.1313.0>}}},{statman_app,start,[normal,[]]}}})

I've not used exrm, so I don't think I'll be able to help you much more. I believe exrm doesn't pull in an application unless it's in the applications list, which was your first issue. Now, you have the issue that this library is starting statman, so, the line in applications is conflicted with that one. I'm not sure if there's a way in exrm to say you need that application, but to not start it.

I was not able to see data on relic server
I have added discorelic info in mix.exs and config.exs

defp deps do
[{:phoenix, "> 1.2.0"},
{:phoenix_pubsub, "> 1.0"},
{:phoenix_html, "> 2.6"},
{:phoenix_live_reload, "> 1.0", only: :dev},
{:gettext, "> 0.11"},
{:discorelic, "> 0.1.0", github: "nogates/discorelic"},
{:cowboy, "~> 1.0"}]

def application do
[mod: {Appname, []},
applications: [:phoenix, :phoenix_pubsub, :phoenix_html, :discorelic, :cowboy, :logger, :gettext]]
end

in config.exs
config :discorelic,
application_name: "appname",
license_key: System.get_env("key")
Please let me know if I'm missing any thing..

Sorry for the late, late reply :( I guess that you probably either solved it or moved to another thing... but yeah, let me know if this is still an issue for you
