Needs some status on the Unicorn

[kaspergrubbe]

Something like

# Displays the current status of the server(s)
#
desc "Displays server status"
task :status, :roles => :app do
  find_servers(:roles => :app).each do |server|
    run "touch #{fetch(:unicorn_pid)}", :hosts => [server]
    pid = capture "cat #{fetch(:unicorn_pid)}", :hosts => [server]
    if pid.to_i > 0 # Server is running
      workers = capture("ps uxww | grep unicorn | grep #{fetch(:application)} | grep #{fetch(:rails_env)} | grep worker ", :hosts => [server]).split("\n").reject{ |l| l.include?("sh -c") }.count
      logger.info "#{server.to_s.ljust(20)}: Server running #{workers} workers on pid #{pid.to_i}"
    else # Server is not running
      logger.info "#{server.to_s.ljust(20)}: Server _NOT_ running!"
    end
  end
end

But simplified.
