# Non-API events captured by CloudTrail
<a name="cloudtrail-non-api-events"></a>

In addition to logging AWS API calls, CloudTrail captures other related events that might have a security or compliance impact on your AWS account or that might help you troubleshoot operational problems. 
+ [AWS service events](non-api-aws-service-events.md) – CloudTrail supports logging non-API service events. These events are created by AWS services but are not directly triggered by a request to a public AWS API. For these events, the `eventType` field is `AwsServiceEvent`.
+ [AWS Management Console sign-in events](cloudtrail-event-reference-aws-console-sign-in-events.md) – CloudTrail logs attempts to sign in to the AWS Management Console, the AWS Discussion Forums, and the AWS Support Center. All IAM user and root user sign-in events, as well as all federated user sign-in events, generate records in CloudTrail. For sign-in events, the `eventType` field is `AwsConsoleSignIn`.
