Follow these steps to set up a crawler for Amazon S3 event notifications for an Amazon S3 target using the Amazon Web Services Management Console or Amazon CLI.

#### [ Amazon Web Services Management Console ]

1. Sign in to the Amazon Web Services Management Console and open the GuardDuty console at [https://console.amazonaws.cn/guardduty/](https://console.amazonaws.cn/guardduty/).

1.  Set your crawler properties. For more information, see [ Setting Crawler Configuration Options on the Amazon Glue console ](https://docs.amazonaws.cn/glue/latest/dg/crawler-configuration.html#crawler-configure-changes-console). 

1.  In the section **Data source configuration**, you are asked * Is your data already mapped to Amazon Glue tables? * 

    By default **Not yet** is already selected. Leave this as the default as you are using an Amazon S3 data source and the data is not already mapped to Amazon Glue tables. 

1.  In the section **Data sources**, choose **Add a data source**.

aws glue update-crawler \
    --name myCrawler \
    --recrawl-policy RecrawlBehavior=CRAWL_EVENT_MODE \
    --schema-change-policy UpdateBehavior=UPDATE_IN_DATABASE,DeleteBehavior=LOG
    --targets '{"S3Targets":[{"Path":"s3://amzn-s3-demo-bucket/", "EventQueueArn": "arn:aws:sqs:us-east-1:012345678910:MyQueue"}]}'
