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, with the exception of m2mBridgeError which is a mandatory observation production configuration. This is the list of configurable observation's production configuration:
- m2mBridgeStarted that is sent when the load process has finished. It needs to be configured in the "Bridge Started Observation" property of the bridge instance used as a template to clone.
- m2mBridgeStopped that is sent when the unload process has finished. It needs to be configured in the "Bridge Stopped Observation" property of the bridge instance used as a template to clone.
- m2mBridgeHeartbeat that is sent with a frequency to advertise that the bridge is alive. It needs to be configured in the "Bridge Heartbeat Observation" property of the bridge instance used as a template to clone.
- m2mBridgeError that is sent every time an error occurs in the execution of the M2MBridge. This is the only mandatory configuration and it needs to be set up in the "Bridge Error Observation" property of the bridge instance used as template to clone.
- Observation types produced by plugins (plugin implementation dependent)
- Placeholders (See Placeholders)
- #{userId} bridge instance user id; set at Edge configuration
- #{tenantId} bridge instance tenant; set at Edge configuration
- #{bridgeId} bridge instance name; composed by concatenating templateId Bridge instance ID to be cloned and bridgeIdPrefix Prefix to add to the unique M2MBridge identifter see Edge configuration
Observations Consumed
The M2MBridge may consume observations of two different types, when those observations have been configured in the observation production configuration.
- observationresourcecrud when a property of a thing instance related to the M2MBridge changes.
- 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 checks multiple conditions. The action of validation is executed at
