How to use LinearScalingStrategy?

[ardell]

I'm not sure exactly how to set up my middleware chain to use the LinearScalingStrategy with DelayedShutdown. Here's what I've got so far, but it only ever scales to 1 worker dyno, even when I add 10+ jobs. Sidekiq's concurrency is set to 1.

# Only auto-scale on Heroku
if ENV['HEROKU_API_KEY'] and ENV['HEROKU_APP']
  Sidekiq.configure_client do |config|
    config.client_middleware do |chain|
      heroku   = Autoscaler::HerokuScaler.new
      strategy = Autoscaler::DelayedShutdown.new(
        Autoscaler::LinearScalingStrategy.new(10, 1),
        60
      )
      Autoscaler::Sidekiq::Client
        .add_to_chain(chain, 'default' => heroku)
        .set_initial_workers(strategy)
    end
  end

  Sidekiq.configure_server do |config|
    config.server_middleware do |chain|
      strategy = Autoscaler::DelayedShutdown.new(
        Autoscaler::LinearScalingStrategy.new(10, 1),
        60
      )
      chain.add(Autoscaler::Sidekiq::Server, Autoscaler::HerokuScaler, strategy)
    end
  end
end

What am I doing wrong?

Have you checked your worker for errors? I think in the server setup you need Autoscaler::HerokuScaler.new
