# Using Internet Monitor with Amazon EventBridge
<a name="CloudWatch-IM-EventBridge-integration"></a>

Health events that Internet Monitor creates for networking issues are published with Amazon EventBridge, so that you can send notifications about a degradation in end users' experience for your application. Both overall (global) health events and local health events are published to EventBridge. Global health events have an impact type of `AVAILABILITY` or `PERFORMANCE`, and local health events have an impact type of `LOCAL_AVAILABILITY` or `LOCAL_PERFORMANCE`.

To use EventBridge to work with Internet Monitor health events, follow the guidance here.

**To set up a rule for Internet Monitor in EventBridge**

1. In the AWS Management Console, in EventBridge, choose **Rules**, then enter a name and a description. Create the rule on the **Default** event bus.

1. In Step 2, select **Other** for the event source, and then, under **Event pattern**, match the following source.

   ```
   {
     "source": ["aws.internetmonitor"]
   }
   ```

1. In Step 3, for the target, select **AWS Service** and **CloudWatch Logs Group**, then select an existing log group or create a new one. 

1. Add any desired tags, and then create the rule. This should populate your selected CloudWatch Logs Group with events from EventBridge.

## Filtering health events by impact type
<a name="CloudWatch-IM-EventBridge-filtering"></a>

You can use event patterns to filter health events by impact type. This is useful if you want to receive only global health events, only local health events, or both.

**Receive only global health events:**

```
{
  "source": ["aws.internetmonitor"],
  "detail": {
    "impactType": ["AVAILABILITY", "PERFORMANCE"]
  }
}
```

**Receive only local health events:**

```
{
  "source": ["aws.internetmonitor"],
  "detail": {
    "impactType": ["LOCAL_AVAILABILITY", "LOCAL_PERFORMANCE"]
  }
}
```

**Receive all health events (default):**

```
{
  "source": ["aws.internetmonitor"]
}
```
