Publish an Alert from Node-RED:
- Drag and drop an inject node.
- Drag and drop a function node.
- Connect the inject to function to mqtt node, respectively.
- Double-tap the function node and write this code:
msg.topic = "YOUR-ALERT-CHANNEL-MQTT-TOPIC";
msg.payload =
{
"severity_level": "MAJOR",
"subject": "An alert subject",
"description": "Description of the alert",
"client_id": "YOUR-DEVICE-CLIENT-ID"
};
return msg;
Severity levels could be the following
- 1.MAJOR
- 2.MINOR
- 3.INFORMATIVE
Important: Alert severities need to be CAPITALIZED when publishing. Failure to do so will result in you not receiving alert notifications, as well as not being able to filter results properly.
