Observations production and consumption

Observations Produced

In addition to custom observations defined by plugins, the M2MBridge can produce observation types regarding its life-cycle. These observations are only produced if they have been configured as such in the bridge instance used to clone.

1. m2mBridgeStarted when load process has finished. Need to be configured in the "Bridge Started Observation" property of the bridge instance used as template to clone.
2. m2mBridgeStopped when unload process has finished. Need to be configured in the "Bridge Stopped Observation" property of the bridge instance used as template to clone.
3. m2mBridgeError if an error occurred at the M2MBridge logic. Need to be configured in the "Bridge Error Observation" property of the bridge instance used as template to clone.
4. Observation types produced by plugins (plugin implementation dependent)

Observations Consumed

The M2MBridge may consume observations of two different types, when those observations have been configured in the observation production configuration.

1. observationresourcecrud when a property of a thing instance related to the M2MBridge changes.
2. command - Observation types implemented for a plugin as a command to be sent to devices. The M2MBridge validates that it has a valid targetthings (the instance type that will process the command)

Observations Validation

The validation of the observation production configuration validates that only one topic has been set for asynchronous operations observationresourcecrud and command
