Background jobs will use the Sidekiq on Redmine. You can Monitoring easily used by Sidekiq plugin.

• Administrator can use the Sidekiq Web UI from the top menu.
• Add to autoload_paths of the Plugin /app/workers.
• IMPORTANT: Anyone trying to use the sidekiq :delay method, use :sidekiq_delay instead because for former has clashes with Redmine safe attributes. There is NO change for :delay_for and :delay_until methods.
