## Properties

- `logBucket`: [IBucket](/cdk/api/v2/docs/aws-cdk-lib.aws_s3.IBucket.html) — Amazon S3 Bucket for monitoring log publishing.

  **Default:** if `logging` is manually set to `true` and a `logBucket` is not provided, a `logBucket` will be automatically generated`.

  You can configure your jobs to send log information to Amazon S3.

- `logging`: boolean — Enable logging for this job.

  **Default:** true - true if values are provided for `logGroup` or `logBucket`, false otherwise

  If set to true, will automatically create a Cloudwatch Log Group and S3 bucket.

- `logGroup`: [ILogGroup](/cdk/api/v2/docs/aws-cdk-lib.aws_logs.ILogGroup.html) — A log group for CloudWatch monitoring.

  **Default:** if `logging` is manually set to `true` and a `logGroup` is not provided, a `logGroup` will be automatically generated`.

  You can configure your jobs to send log information to CloudWatch Logs.

- `logStreamNamePrefix`: string — A log stream name prefix for Cloudwatch monitoring.

  **Default:** Log streams created in this log group have no default prefix
