Using the UI
The central Worker configuration can be managed through the WranglerView UI from the Supervisor. Using the Workers tab, select one or more machines, <right-click> to get the menu, and choose "Configure on Supervisor"
The worker configuration UI will be shown. Make any desired changes. Any values that you edit will have their labels turn green, as in the worker_description field to the right.
Clicking OK will save the changes to the central worker configuration, at which time the Supervisor will automatically instruct all workers to re-request their configuration from the Supervisor. No Supervisor or Worker restart is necessary. Any Workers not currently running will receive the changes when they next start up.
