An application logs a structured JSON line for every transaction, including a 'status' field. A DevOps engineer needs to create a real-time alarm that triggers when the number of 'status' = 'ERROR' entries exceeds 10 in a 5-minute window. The logs are already streaming to CloudWatch Logs. What should the engineer do?

Create a CloudWatch alarm directly on the log group's 'ErrorCount' metric.

Create a CloudWatch metric filter on the log group for 'status' = 'ERROR', then create an alarm on that metric with a threshold of 10 and a period of 5 minutes.

Create an Amazon EventBridge rule that matches on the log event content and triggers an SNS topic.

Use CloudWatch Logs Insights to create an alarm based on a query.

What information is typically found in an AWS CloudTrail log event?

The CPU utilization of EC2 instances

The configuration state of resources

The API call, the user, and the timestamp

Which AWS services can be integrated with AWS X-Ray for tracing?

AWS CloudFormation and AWS CloudTrail

Amazon API Gateway and AWS Lambda
