XMR for short, the message relay is responsible for pushing messages from the CMS to the Players. XMR is used for any Player Actions that need to be taken immediately. Examples of this are:
- Change Layout
- Collect Now
- Revert to Schedule
- Execute Command
XMR uses a technology called ZeroMQ which must be available on your web server before it will function. If not enabled the fault page will show a warning.
Xibo will function without XMR running, but will not run any player actions. Scheduling and Layouts will function as normal.
