You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cleanup_queues.rb
    path of file: ./repos/vets-api/app/sidekiq/sidekiq_alive
    
    the code of the file until where you have to start completion: # frozen_strin
    
  def perform
    # Get all hostnames of Sidekiq processes
    processes = Sidekiq::ProcessSet.new

    vsp_env = Settings.vsp_environment
    current_env = vsp_env == 'development' ? 'dev' : vsp_env
    hostname_suffix = "sidekiq_alive-#{current_env}-api.va.gov"
    if current_env == 'production'
      hostname_suffix = 'sidekiq_alive-api.va.gov' # No env - api.va.gov NOT production-api.va.gov
    end
