"EventBridge sends metrics to Amazon CloudWatch every minute for everything from the number of matched events to the number of times a target is invoked by a rule." from https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-monitoring.html B: SQS, irrelevant C: 'Check for events', this wording is confusing but could mean something in wrong context. I would have chosen C if A wasn't an option D: CloudTrail is for AWS resource monitoring so irrelevant

A per https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-monitoring.html Not B because SQS is not even involved here Not C because EventBridge sends only metrics, not detailed logs, to CloudWatch Not D, many fall for CloudTrail supposedly recording "API calls", but this is about calls for the EventBridge API to AWS, not calls to 3rd party APIs by EventBridge.

Option A, "Check for metrics in Amazon CloudWatch in the namespace for AWS/Events," primarily provides aggregated metrics related to EventBridge, but it may not give detailed information about individual events or their specific content. Metrics in CloudWatch can give you an overview of how many events are being processed, but for detailed inspection of events and their conditions, checking CloudWatch Logs (option C) is more appropriate. CloudWatch Logs allow you to see the actual event data and details, providing a more granular view that is useful for troubleshooting and understanding the specifics of why a third-party API is not receiving incoming traffic.

A Events not generating logs in cloudwatch and cloudtrail. only metric data is available.

CloudWatch is a monitoring service for AWS resources and applications. CloudTrail is a web service that records API activity in your AWS account. CloudWatch monitors applications and infrastructure performance in the AWS environment. CloudTrail monitors actions in the AWS environment.

C should be correct, I check in AWS management concole.

should be A

Check the trails in AWS CloudTrail for the EventBridge events.

Amazon CloudWatch Logs is a service that collects and stores logs from Amazon Web Services (AWS) resources. These logs can be used to troubleshoot problems, monitor performance, and audit activity. The other options are incorrect: Option A: CloudWatch metrics are used to track the performance of AWS resources. They are not used to store events. Option B: Amazon SQS dead-letter queues are used to store messages that cannot be delivered to their intended recipients. They are not used to store events. Option D: AWS CloudTrail is a service that records AWS API calls. It can be used to track the activity of EventBridge rules, but it does not store the events themselves.

The answer is D: "CloudTrail captures API calls made by or on behalf of your AWS account from the EventBridge console and to EventBridge API operations." (https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-logging-monitoring.html)

The key reasons: AWS CloudTrail provides visibility into EventBridge operations by logging API calls made by EventBridge. Checking the CloudTrail trails will show the PutEvents API calls made when EventBridge rules match an event pattern. CloudTrail will also log the Invoke API call when the rule target is triggered. CloudWatch metrics and logs contain runtime performance data but not info on rule evaluation and targeting. SQS dead letter queues collect failed event deliveries but won't provide insights on successful invocations. CloudTrail is purpose-built to log operational events and API activity so it can confirm if the EventBridge rule is being evaluated and triggering the target as expected.

Option A is the most appropriate solution because Amazon EventBridge publishes metrics to Amazon CloudWatch. You can find relevant metrics in the "AWS/Events" namespace, which allows you to monitor the number of events matched by the rule and the number of invocations to the rule's target.
