Ruby / Sidekiq - queue analyzing / reporting

We currently have a chrome extension which uses Ruby and has a task queue using sidekiq to process requests. As far as I can see we are unable to currently see which users are sending large amount of tasks and we'd like to be able to see this and also report on it.

The code is available via github.

Please ensure you provide at least one example of a sidekiq based project you have worked on.
