Create an Email-Alert Trigger for Connector Online Status
In this guide, you'll set up an alert and a trigger for Litmus Edge's default MQTT SSL connector that connects to Litmus Edge Manager. Then you will simulate a disconnection for the connector to trigger the alert.
- If you haven't yet connected your Litmus Edge instance to Litmus Edge Manager, see Activate an Edge Device. A Litmus Edge instance needs to be activated in Litmus Edge Manager before it can trigger alerts.
In this step you'll create an email notification alert. Next, you will create a trigger that will use the email notification alert. See Alerts for additional details.
