Mango M2M Functional overview
Users first create "data sources", which are typically based upon a protocol. Data sources
define "points", which are representations of single pieces of data and are configurable in many
ways including data logging, text rendering, and chart rendering. (There are two pages to view: data point
details - read only - and data point editing.) Both of these objects allow user permissions to be set in
very granular ways. These points can be monitoring on the "watch list", or users can build
graphical views using drag-and-drop functionality on uploaded background images.
Users could stop there and only use the system for manual monitoring, control, and data logging, but the
automation power of Mango is in the event subsystem. Events are split into two parts: the detection and the
handling. These parts can be arbitrarily paired in a one-to-many fashion, and can also be chained.
An event detector can be something like a high limit (for analog data) or a binary/multi-state state. For
example, you can define conditions such as "when the humidity exceeded 60% for more than 1 hour".
(Conditions depend on the data type of the point, so a somewhat different list of options will be displayed
for different points.) There are also hard-coded event detectors for data source exceptions, system
exceptions, and other things such as new Mango version notifications.
On the handler side, users decide what should happen when an event is raised. Currently there are two
handlers: email notification and set point. When the event is raised, email notifications are sent to
specified email addresses, users, or mailing lists. Optionally, if an event is still active at some
timeout, the event can also be sent to an escalation list. Finally, upon event deactivation, notifications
can optionally be sent to all event participants.
The set point handler allows the user to define how a point should be set upon the raising of an event.
This is how conditions can be chained together, since the new value of the set point may raise new
events.
This represents the general runtime usage of the system. There are also many advanced functions as well as
administrative, diagnostic, and management features of the system as well.
