In this use case, you'll set up an alert and a trigger for the default MQTT SSL connector in Belden Horizon Data Operations (BHDO) that connects to Belden Horizon Data Manager (BHDM). Then you will simulate a disconnection for the connector to trigger the alert.

# Before You Begin

- You will have to enable SMTP from the Belden Horizon Data Manager Admin Console. See [Email](docId\:L2yv7i3mkj2HVMA2bLbXu) to learn more. 
- If you haven't yet connected your BHDO instance to BHDM, see [Activate an Edge Device](docId\:bbgh94p0zHJUZ0JuaO6bY). A BHDO instance needs to be activated in BHDM before it can trigger alerts.

# Step 1: Set Up an Email-Alert based Trigger 

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](docId\:qcRiKcFeXyjQAbqJTKJmr) for additional details.

From Belden Horizon Data Manager, navigate to **Alerts** and follow the steps below. 

## Step 1a: Set Up an Email Alert

**To set up an email alert: **

1. From the *Alerts *pane, click the **Add new Action** icon.

# Step 2: Simulate a Disconnection

From BHDO you will simulate a disconnection with BHDM.

**To simulate a disconnection:**

1. Log in to Belden Horizon Data Operations.
2. From the navigation panel, select **Integration**.
   The *Integration *pane appears.
3. From the *generic-mqtt-ssl* tile, click the toggle to disable the connector.

# Step 3: Verify Successful Trigger and Alert

From Belden Horizon Data Manager, you will verify the simulated disconnection.

**To verify the trigger and alert:**

1. Log in to Belden Horizon Data Manager.
2.
   Select the appropriate company and project. 
   The *Dashboard *pane appears for the project.
3.
   Scroll down to see the alert.

The email address that was configured for the alert will also receive the respective alert email.
