Running on Heroku

I'm having a hard time trying to run Fnordmetric in Heroku. Basically, what happens is that Heroku won't allow to start the EM worker on the same dyno. Is there a way to manually run the Fnordmetric worker using a rake command or something similar?

First of all, sorry for my late answer. From fnordmetric v0.7.3 upwards you can do the following:

$ ruby my_fnordmetric_app.rb worker

This seems to work fine when you have FnordMetric.standalone. However, standalone does not appear to allow you to pass in options. Is there a recommended way to run it with something like

FnordMetric.embedded(
  :redis_url => ENV['REDISTOGO_URL'] || "redis://localhost:6379",
  :inbound_stream => ["0.0.0.0", "1337"]
)

And, any idea how best to set the inbound_stream port on heroku?

hm, maybe you are looking for this?

FnordMetric.server_configuration = {
  :redis_url => ENV['REDISTOGO_URL'] || "redis://localhost:6379",
  :inbound_stream => ["0.0.0.0", "1337"]
}

FnordMetric.standalone

Heroku won't allow to spawn a random port so this line

:inbound_stream => ["0.0.0.0", "1337"]

Will fail in Heroku.

Finally, thank you for your answer and your willingness to help, you're awesome.

You can disable the inbound stream by passing:

FnordMetric.server_configuration = {
  :redis_url => ENV['REDISTOGO_URL'] || "redis://localhost:6379",
  :inbound_stream => false
}```

I created a sample repo at https://github.com/fairchild/fnordystats. I think it can likely be done much cleaner than i have done there. Seems when inbound_stream is set to false, i get errors like cant start FnordMetric::InboundStream. port in use?
