# Monitoring Amazon Trusted Advisor check results with Amazon EventBridge
<a name="cloudwatch-events-ta"></a>

You can use EventBridge to detect when your checks for Trusted Advisor change status. Then, based on the rules that you create, EventBridge invokes one or more target actions when the status changes to a value that you specify in a rule.

Depending on the status change, you can send notifications, capture status information, take corrective action, initiate events, or take other actions. For example, you can specify the following target types if a check changes status from no problems detected (green) to recommended action (red).
+ Use an Amazon Lambda function to pass a notification to a Slack channel.
+ Push data about the check to an Amazon Kinesis stream to support comprehensive and real-time status monitoring.
+ Send an Amazon Simple Notification Service topic to your email.
+ Get notified with an Amazon CloudWatch alarm action.

For more information about on how to use EventBridge and Lambda functions to automate responses for Trusted Advisor, see [Trusted Advisor tools](https://github.com/aws/Trusted-Advisor-Tools) in GitHub.

**Notes**  
Trusted Advisor delivers events on a best effort basis. Events are not always guaranteed to be delivered to EventBridge.
You must have a Business, Enterprise On-Ramp, or Enterprise Amazon Web Services Support plan to create a rule for Trusted Advisor checks. For more information, see [Change Amazon Web Services Support Plans](changing-support-plans.md).
As Trusted Advisor is a Global service, all Events are emitted to EventBridge in the US East (N. Virginia) Region.

Follow this procedure to create an EventBridge rule for Trusted Advisor. Before you create event rules, do the following:
+ Familiarize yourself with events, rules, and targets in EventBridge. For more information, see [What is Amazon EventBridge?](https://docs.amazonaws.cn/eventbridge/latest/userguide/eb-what-is.html) in the *Amazon EventBridge User Guide*.
+ Create the target that you will use in your event rule.
