The Oaf Aggregation Framework is a framework for monitoring various systems and aggregating status information into a single view i.e. is everything ok? It is designed to support an individual's view of their world and any number of key inputs to it.

• Systems - Systems represent an input point, something in the real or virtual world has developed a status and would like to communicate it to you. They provide a simple end-point and get/post inferface to accept data. Systems have a few basic properties:
  • status - a one word description of the status of the reporting state commonly something from ['none', 'ok', 'working', 'success', 'warning', 'error']
  • message - A free-form description of the status
  • color - the color that this system matches to the given status as a rgb tuple
  • blink - a blink speed from 0-7
  • level - how importantant this status is compared to other statuses that this system might have
• Notifiers - notifiers expose the state of a system or systems for view. In the trivial case this is equivalent to going to read the systems page itself, but notifiers can report via other protocols, such as push, pager, or similar.
• Servers - Servers tie together lists of systems and notifers. Beyond the simple repeating function they will process the levels and relative importance of the various systems to pick one system that should be the user's greatest concern. This is the color, status, blink, and message that is sent to all notifiers.
  • SubServers allow the summarization logic to be applied hierachically, serving as servers and systems and thereby supporting notifications for designated areas.
