Alarms sent by the asset do not reach ThingWorx Platform
User Actions
The user must perform the following actions when faced with this error:
• Verify that the Connector is still running or attached. To do this, navigate to the > page and validate that the Connector is available in the list.
• Verify if the alarms property exist on the Thing and if the Axeda Compatibility Extension is installed. Check if the Thing was created using the appropriate Axeda Thing Template. If yes, then the alarms property would have automatically been created.
• Check if the WritePropertyError advisory event was sent to the Connection Services Hub. This indicates that the Connector attempted to write a property for a Thing, but could not do it because of a problem.
Administrator Actions
In addition to the steps that the user performs, the administrator must perform the following steps when faced with this error:
• If you are running a multi-node connector environment, verify that all the Connectors are still running and connected.
• Check the > page and validate that the correct number of Connectors are available in the list. If all the Connectors are not displayed in the list, traffic could land on a broken connector and fail to reach the ThingWorx Platform.
• Monitor metrics from the Connector nodes to validate that each eMessage Connector is processing messages from the load balancer. For more information, refer to
Metrics Monitoring.
• Use a packet sniffer to validate that network packets are being sent:
◦ Between the load balancer and each connector node.
◦ Between each connector node and ThingWorx Platform.
