How to tell sidekiq to send requests every 2 seconds?

Question

Ruby on Rails

I'm not very familiar with Sidekiq yet, so the question might be confusing.
The thing is that there is my server, and there is server N, on which I want to check the existence of a file every 2 seconds. 2 seconds - this is because the server owners themselves gave such a condition. I also have a Worker that actually climbs to that server and checks what is there and how.
But I don’t understand a little, how can I make the Worker make requests every 2 seconds? Make another Worker, to whom to give a bunch of schedules to launch another Worker, or what?
