How can I make all log entries within each 5-minute interval appear in the same log stream for an AWS CDK REST API?

Question

I have created a REST API using the AWS CDK and specified the following for the access logs:

const apiLogGroup = new cdk.aws_logs.LogGroup(this, `${this.apiName}-logGroup`, {
  retention: cdk.aws_logs.RetentionDays.ONE_MONTH,
  logGroupName: `/aws/apigateway/${this.apiName}`,
});

const accessLogDestination = new apigw.LogGroupLogDestination(apiLogGroup);
const accessLogFormat = apigw.AccessLogFormat.custom(
  JSON.stringify({
    requestId: apigw.AccessLogField.contextRequestId(),
    email: apigw.AccessLogField.contextAuthorizer('email'),
    path: apigw.AccessLogField.contextResourcePath(),
    method: apigw.AccessLogField.contextHttpMethod(),
  })
);

new apigw.RestApi(this, this.apiName, {
  deployOptions: {
    accessLogDestination,
    accessLogFormat,
  }
});

However I get dozens of new logstreams every second which contain only a single log. I would like to have all logs of say a 5 minute interval in the same logstream. Is there a way to ensure that all log entries within each 5-minute interval end up in the same log stream?

Answer 1

You can't. Which log stream a service writes to is not user-configurable, either with or without the CDK. See this related question: When does AWS CloudWatch create new log streams?.

Use the FilterLogEvents API or LogInsights to abstract away the log stream details if they are getting in your way.
