PutEventSelectors

Configures event selectors (also referred to as basic event selectors) or advanced event selectors for your trail. You can use either AdvancedEventSelectors or EventSelectors, but not both. If you apply AdvancedEventSelectors to a trail, any existing EventSelectors are overwritten.

You can use AdvancedEventSelectors to log management events, data events for all resource types, and network activity events.

You can use EventSelectors to log management events and data events for the following resource types:

You can't use EventSelectors to log network activity events.

If you want your trail to log Insights events, be sure the event selector or advanced event selector enables logging of the Insights event types you want configured for your trail. For more information about logging Insights events, see Logging Insights events in the CloudTrail User Guide. By default, trails created without specific event selectors are configured to log all read and write management events, and no data events or network activity events.

When an event occurs in your account, CloudTrail evaluates the event selectors or advanced event selectors in all trails. For each trail, if the event matches any event selector, the trail processes and logs the event. If the event doesn't match any event selector, the trail doesn't log the event.

Example

The PutEventSelectors operation must be called from the Region in which the trail was created; otherwise, an InvalidHomeRegionException exception is thrown.

You can configure up to five event selectors for each trail.

You can add advanced event selectors, and conditions for your advanced event selectors, up to a maximum of 500 values for all conditions and selectors on a trail. For more information, see Logging management events, Logging data events, Logging network activity events, and Quotas in AWS CloudTrail in the AWS CloudTrail User Guide.

Examples

Example

The following example shows how to use advanced event selectors to log all management events (both readOnly and writeOnly), include PutObject and DeleteObject data events for the S3 objects in two S3 bucket prefixes, and log network activity events for AWS KMS. As shown here, you can use advanced event selectors to select not only the S3 prefix names by ARN, but the names of the specific events that you want to log.

{
   "AdvancedEventSelectors": [ 
      {
         "Name": "Log all management events",
         "FieldSelectors": [
            { "Field": "eventCategory", "Equals": ["Management"] }
          ]
      },
      {
         "Name": "Log PutObject and DeleteObject data events for two S3 prefixes",
         "FieldSelectors": [
            { "Field": "eventCategory", "Equals": ["Data"] },
            { "Field": "resources.type", "Equals": ["AWS::S3::Object"] },
            { "Field": "eventName", "Equals": ["PutObject","DeleteObject"] },
            { "Field": "resources.ARN", "StartsWith": ["arn:aws:s3:::amzn-s3-demo-bucket/prefix","arn:aws:s3:::amzn-s3-demo-bucket2/prefix2"] }
         ]
         
      },
      {
         "Name": "Log network activity events for AWS KMS",
         "FieldSelectors": [
            {"Field": "eventCategory", "Equals": ["NetworkActivity"]},
            {"Field": "eventSource", "Equals": ["kms.amazonaws.com"]}
         ]
      }
   ],
   "TrailName": "myTrail"
