Managing trails with the AWS CLI

The AWS CLI includes several other commands that help you manage your trails. These commands add tags to trails, get trail status, start and stop logging for trails, and delete a trail. You must run these commands from the same AWS Region where the trail was created (its Home Region). When using the AWS CLI, remember that your commands run in the AWS Region configured for your profile. If you want to run the commands in a different Region, either change the default Region for your profile, or use the --region parameter with the command.

Add one or more tags to a trail

To add one or more tags to an existing trail, run the add-tags command.

The following example adds a tag with the name Owner and the value of Mary to a trail with the ARN of arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail in the US East (Ohio) Region. 

aws cloudtrail add-tags --resource-id arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail --tags-list Key=Owner,Value=Mary --region us-east-2

If successful, this command returns nothing.

List tags for one or more trails

To view the tags associated with one or more existing trails, use the list-tags command.

The following example lists the tags for Trail1 and Trail2.

aws cloudtrail list-tags --resource-id-list arn:aws:cloudtrail:us-east-2:123456789012:trail/Trail1 arn:aws:cloudtrail:us-east-2:123456789012:trail/Trail2

If successful, this command returns output similar to the following.

{
 "ResourceTagList": [
     {
         "ResourceId": "arn:aws:cloudtrail:us-east-2:123456789012:trail/Trail1",
         "TagsList": [
             {
                 "Value": "Alice",
                 "Key": "Name"
             },
             {
                 "Value": "Ohio",
                 "Key": "Location"
             }
         ]
     },
     {
         "ResourceId": "arn:aws:cloudtrail:us-east-2:123456789012:trail/Trail2",
         "TagsList": [
             {
                 "Value": "Bob",
                 "Key": "Name"
             }
         ]
     }
  ]
}

Remove one or more tags from a trail

To remove one or more tags from an existing trail, run the remove-tags command.

The following example removes tags with the names Location and Name from a trail with the ARN of arn:aws:cloudtrail:us-east-2:123456789012:trail/Trail1 in the US East (Ohio) Region. 

aws cloudtrail remove-tags --resource-id arn:aws:cloudtrail:us-east-2:123456789012:trail/Trail1 --tags-list Key=Name Key=Location --region us-east-2

If successful, this command returns nothing.

Retrieving trail settings and the status of a trail

Run the describe-trails command to retrieve information about trails in an AWS Region. The following example returns information about trails configured in the US East (Ohio) Region.

aws cloudtrail describe-trails --region us-east-2

If the command succeeds, you see output similar to the following. 

{
  "trailList": [
    {
      "Name": "my-trail",
      "S3BucketName": "amzn-s3-demo-bucket1",
      "S3KeyPrefix": "my-prefix",
      "IncludeGlobalServiceEvents": true,
      "IsMultiRegionTrail": true,
      "HomeRegion": "us-east-2"
      "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail",
      "LogFileValidationEnabled": false,
      "HasCustomEventSelectors": false, 
      "SnsTopicName": "my-topic",
      "IsOrganizationTrail": false,
    },
    {
      "Name": "my-special-trail",
      "S3BucketName": "amzn-s3-demo-bucket2",
      "S3KeyPrefix": "example-prefix",
      "IncludeGlobalServiceEvents": false,
      "IsMultiRegionTrail": false,
      "HomeRegion": "us-east-2",
      "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-special-trail",
      "LogFileValidationEnabled": false,
      "HasCustomEventSelectors": true,
      "IsOrganizationTrail": false
    },
    {
      "Name": "my-org-trail",
      "S3BucketName": "amzn-s3-demo-bucket3",
      "S3KeyPrefix": "my-prefix",
      "IncludeGlobalServiceEvents": true,
      "IsMultiRegionTrail": true,
      "HomeRegion": "us-east-1"
      "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-org-trail",
      "LogFileValidationEnabled": false,
      "HasCustomEventSelectors": false, 
      "SnsTopicName": "my-topic",
      "IsOrganizationTrail": true
    }
  ]
}

Run the get-trail command to retrieve settings information about a specific trail. The following example returns settings information for a trail named my-trail.

aws cloudtrail get-trail - -name my-trail

If successful, this command returns output similar to the following.

{
   "Trail": {
      "Name": "my-trail",
      "S3BucketName": "amzn-s3-demo-bucket",
      "S3KeyPrefix": "my-prefix",
      "IncludeGlobalServiceEvents": true,
      "IsMultiRegionTrail": true,
      "HomeRegion": "us-east-2"
      "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/my-trail",
      "LogFileValidationEnabled": false,
      "HasCustomEventSelectors": false, 
      "SnsTopicName": "my-topic",
      "IsOrganizationTrail": false,
   }
}

Run the get-trail-status command to retrieve the status of a trail. You must either run this command from the AWS Region where it was created (the Home Region), or you must specify that Region by adding the --region parameter.

Note

If the trail is an organization trail and you are a member account in the organization in AWS Organizations, you must provide the full ARN of that trail, and not just the name.

aws cloudtrail get-trail-status --name my-trail

If the command succeeds, you see output similar to the following. 

{
    "LatestDeliveryTime": 1441139757.497, 
    "LatestDeliveryAttemptTime": "2015-09-01T20:35:57Z", 
    "LatestNotificationAttemptSucceeded": "2015-09-01T20:35:57Z", 
    "LatestDeliveryAttemptSucceeded": "2015-09-01T20:35:57Z", 
    "IsLogging": true, 
    "TimeLoggingStarted": "2015-09-01T00:54:02Z", 
    "StartLoggingTime": 1441068842.76, 
    "LatestDigestDeliveryTime": 1441140723.629, 
    "LatestNotificationAttemptTime": "2015-09-01T20:35:57Z", 
    "TimeLoggingStopped": ""
}

In addition to the fields shown in the preceding JSON code, the status contains the following fields if there are Amazon SNS or Amazon S3 errors:

  • LatestNotificationError. Contains the error emitted by Amazon SNS if a subscription to a topic fails.

  • LatestDeliveryError. Contains the error emitted by Amazon S3 if CloudTrail cannot deliver a log file to a bucket.

Configuring CloudTrail Insights event selectors

Enable Insights events on a trail by running the put-insight-selectors, and specifying ApiCallRateInsight, ApiErrorRateInsight, or both as the value of the InsightType attribute. To view the Insights selector settings for a trail, run the get-insight-selectors command. You must either run this command from the AWS Region where the trail was created (the Home Region), or you must specify that Region by adding the --region parameter to the command.

Note

To log Insights events for ApiCallRateInsight, the trail must log write management events. To log Insights events for ApiErrorRateInsight, the trail must log read or write management events.

Example trail that logs Insights events

The following example uses put-insight-selectors to create an Insights event selector for a trail named TrailName3. This enables Insights event collection for the TrailName3 trail. The Insights event selector logs both ApiErrorRateInsight and ApiCallRateInsight Insights event types.

aws cloudtrail put-insight-selectors --trail-name TrailName3 --insight-selectors '[{"InsightType": "ApiCallRateInsight"},{"InsightType": "ApiErrorRateInsight"}]'

The example returns the Insights event selector that is configured for the trail.

{
   "InsightSelectors": 
      [
         {
            "InsightType": "ApiErrorRateInsight"
         },
         {
            "InsightType": "ApiCallRateInsight"
         }
      ],
   "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName3"
}

Example: Turn off collection of Insights events

The following example uses put-insight-selectors to remove the Insights event selector for a trail named TrailName3. Clearing the JSON string of Insights selectors disables Insights event collection for the TrailName3 trail.

aws cloudtrail put-insight-selectors --trail-name TrailName3 --insight-selectors '[]'

The example returns the now-empty Insights event selector that is configured for the trail.

{
   "InsightSelectors": [ ],
   "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName3"
}

Configuring advanced event selectors

You can use advanced event selectors to log management events, data events for all resource types, and network activity events. In contrast, you can use basic event selectors to log management events and data events for the AWS::DynamoDB::Table, AWS::Lambda::Function, and AWS::S3::Object resource types. You can use either basic event selectors, or advanced event selectors, but not both. If you apply advanced event selectors to a trail that is using basic event selectors, the basic event selectors are overwritten.

To convert a trail to advanced event selectors, run the get-event-selectors command to confirm the current event selectors, and then configure the advanced event selectors to match the coverage of the previous event selectors, then add any additional selectors.

You must either run the get-event-selectors command from the AWS Region where the trail was created (the Home Region), or you must specify that Region by adding the --region parameter.

aws cloudtrail get-event-selectors --trail-name TrailName
Note

If the trail is an organization trail, and you are signed in with a member account in the organization in AWS Organizations, you must provide the full ARN of the trail, and not just the name.

The following example shows the settings for a trail that is using advanced event selectors to log management events. By default, a trail is configured to log all management events and no data events or network activity events.

{
    "TrailARN": "arn:aws:cloudtrail:us-east-1:123456789012:trail/management-events-trail",
    "AdvancedEventSelectors": [
        {
            "Name": "Management events selector",
            "FieldSelectors": [
                {
                    "Field": "eventCategory",
                    "Equals": [
                        "Management"
                    ]
                }
            ]

        }
    ]
}

To create an advanced event selector, run the put-event-selectors command. When an event occurs in your account, CloudTrail evaluates the configuration for your trails. If the event matches any advanced event selector for a trail, the trail processes and logs the event. You can configure up to 500 conditions on a trail, including all values specified for all advanced event selectors on your trail. For more information, see Logging data events and Logging network activity events.

Example trail with specific advanced event selectors

The following example creates custom advanced event selectors for a trail named TrailName to include read and write management events (by omitting the readOnly selector), PutObject and DeleteObject data events for all Amazon S3 bucket/prefix combinations except for a bucket named amzn-s3-demo-bucket, data events for an AWS Lambda function named MyLambdaFunction, and network activity events for AWS KMS access denied events over a VPC endpoint. Because these are custom advanced event selectors, each set of selectors has a descriptive name. Note that a trailing slash is part of the ARN value for S3 buckets.

aws cloudtrail put-event-selectors --trail-name TrailName --advanced-event-selectors
'[
  {
    "Name": "Log readOnly and writeOnly management events",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Management"] }
    ]
  },
  {
    "Name": "Log PutObject and DeleteObject events for all but one bucket",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Data"] },
      { "Field": "resources.type", "Equals": ["AWS::S3::Object"] },
      { "Field": "eventName", "Equals": ["PutObject","DeleteObject"] },
      { "Field": "resources.ARN", "NotStartsWith": ["arn:aws:s3:::amzn-s3-demo-bucket/"] }
    ]
  },
  {
    "Name": "Log data plane actions on MyLambdaFunction",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Data"] },
      { "Field": "resources.type", "Equals": ["AWS::Lambda::Function"] },
      { "Field": "resources.ARN", "Equals": ["arn:aws:lambda:us-east-2:111122223333:function/MyLambdaFunction"] }
    ]
  },
  {
     "Name": "Audit AccessDenied AWS KMS events over a VPC endpoint",
     "FieldSelectors": [
       { "Field": "eventCategory", "Equals": ["NetworkActivity"]},
       { "Field": "eventSource", "Equals": ["kms.amazonaws.com"]},
       { "Field": "errorCode", "Equals": ["VpceAccessDenied"]}
     ]
  }
]'

The example returns the advanced event selectors that are configured for the trail.

{
  "AdvancedEventSelectors": [
    {
      "Name": "Log readOnly and writeOnly management events",
      "FieldSelectors": [
        {

         },
         {
           "Field": "eventSource",
           "Equals": ["kms.amazonaws.com"]
         },
         {
           "Field": "errorCode",
           "Equals": ["VpceAccessDenied"]
         }
       ]
     }
  ],
  "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

Example trail that uses custom advanced event selectors to log Amazon S3 on AWS Outposts data events

The following example shows how to configure your trail to include all data events for all Amazon S3 on AWS Outposts objects in your outpost. In this release, the supported value for S3 on AWS Outposts events for the resources.type field is AWS::S3Outposts::Object.

aws cloudtrail put-event-selectors --trail-name TrailName --region region \
--advanced-event-selectors \
'[
    {
            "Name": "OutpostsEventSelector",
            "FieldSelectors": [
                { "Field": "eventCategory", "Equals": ["Data"] },
                { "Field": "resources.type", "Equals": ["AWS::S3Outposts::Object"] }
            ]
        }
]'

The command returns the following example output.

{
    "AdvancedEventSelectors": [
        {
            "Name": "OutpostsEventSelector",
            "FieldSelectors": [
                {
                    "Field": "eventCategory",
                    "Equals": [
                        "Data"
                    ]
                },
                {
                    "Field": "resources.type",
                    "Equals": [
                        "AWS::S3Outposts::Object"
                    ]
                }
            ]
        }
    ],
  "TrailARN": "arn:aws:cloudtrail:region:123456789012:trail/TrailName"
}

Example trail that uses advanced event selectors to exclude AWS Key Management Service events

The following example creates an advanced event selector for a trail named TrailName to include read-only and write-only management events (by omitting the readOnly selector), but to exclude AWS Key Management Service (AWS KMS) events. Because AWS KMS events are treated as management events, and there can be a high volume of them, they can have a substantial impact on your CloudTrail bill if you have more than one trail that captures management events.

If you choose not to log management events, AWS KMS events are not logged, and you cannot change AWS KMS event logging settings.

To start logging AWS KMS events to a trail again, remove the eventSource selector, and run the command again.

aws cloudtrail put-event-selectors --trail-name TrailName \
--advanced-event-selectors '
[
  {
    "Name": "Log all management events except KMS events",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Management"] },
      { "Field": "eventSource", "NotEquals": ["kms.amazonaws.com"] }
    ]
  }
]'

The example returns the advanced event selectors that are configured for the trail.

{
  "AdvancedEventSelectors": [
    {
      "Name": "Log all management events except KMS events",
      "FieldSelectors": [
        {
          "Field": "eventCategory", 
          "Equals": [ "Management" ]
        },
        {
          "Field": "eventSource", 
          "NotEquals": [ "kms.amazonaws.com" ]
        }
      ]
    }
  ],
  "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

To start logging excluded events to a trail again, remove the eventSource selector, as shown in the following command.

aws cloudtrail put-event-selectors --trail-name TrailName \
--advanced-event-selectors '
[
  {
    "Name": "Log all management events",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Management"] }
    ]
  }
]'

Example trail that uses advanced event selectors to exclude Amazon RDS Data API management events

The following example creates an advanced event selector for a trail named TrailName to include read-only and write-only management events (by omitting the readOnly selector), but to exclude Amazon RDS Data API management events. To exclude Amazon RDS Data API management events, specify the Amazon RDS Data API event source in the string value for the eventSource field: rdsdata.amazonaws.com.

If you choose not to log management events, Amazon RDS Data API management events are not logged, and you cannot change Amazon RDS Data API event logging settings.

To start logging Amazon RDS Data API management events to a trail again, remove the eventSource selector, and run the command again.

aws cloudtrail put-event-selectors --trail-name TrailName \
--advanced-event-selectors '
[
  {
    "Name": "Log all management events except Amazon RDS Data API management events",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Management"] },
      { "Field": "eventSource", "NotEquals": ["rdsdata.amazonaws.com"] }
    ]
  }
]'

The example returns the advanced event selectors that are configured for the trail.

{
  "AdvancedEventSelectors": [
    {
      "Name": "Log all management events except Amazon RDS Data API management events",
      "FieldSelectors": [
        {
          "Field": "eventCategory", 
          "Equals": [ "Management" ]
        },
        {
          "Field": "eventSource", 
          "NotEquals": [ "rdsdata.amazonaws.com" ]
        }
      ]
    }
  ],
  "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

To start logging excluded events to a trail again, remove the eventSource selector, as shown in the following command.

aws cloudtrail put-event-selectors --trail-name TrailName \
--advanced-event-selectors '
[
  {
    "Name": "Log all management events",
    "FieldSelectors": [
      { "Field": "eventCategory", "Equals": ["Management"] }
    ]
  }
]'

Configuring basic event selectors

You can only use basic event selectors to log management events and data events for the AWS::DynamoDB::Table, AWS::Lambda::Function, and AWS::S3::Object resource types. You can log management events, all data resource types, and network activity events by using advanced event selectors.

You can use either basic event selectors, or advanced event selectors, but not both. If you apply basic event selectors to a trail that is using advanced event selectors, the advanced event selectors are overwritten.

To view the event selector settings for a trail, run the get-event-selectors command. You must either run this command from the AWS Region where it was created (the Home Region), or you must specify that Region by using the --region parameter. 

aws cloudtrail get-event-selectors --trail-name TrailName
Note

If the trail is an organization trail and you are a member account in the organization in AWS Organizations, you must provide the full ARN of that trail, and not just the name.

The following example shows the settings for a trail that is using basic event selectors to log management events.

{
    "EventSelectors": [
        {
            "ExcludeManagementEventSources": [],
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "All"
        }
    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

To create an event selector, run the put-event-selectors command. If you want to log Insights events on the trail, be sure the event selector enables logging of the Insights types you want configured your trail. For more information about logging Insights events, see Working with CloudTrail Insights.

When an event occurs in your account, CloudTrail evaluates the configuration for your trails. If the event matches any event selector for a trail, the trail processes and logs the event. You can configure up to 5 event selectors for a trail and up to 250 data resources for a trail. For more information, see Logging data events.

Example trail with specific event selectors

The following example creates an event selector for a trail named TrailName to include read-only and write-only management events, data events for two Amazon S3 bucket/prefix combinations, and data events for a single AWS Lambda function named hello-world-python-function. 

aws cloudtrail put-event-selectors --trail-name TrailName --event-selectors '[{"ReadWriteType": "All","IncludeManagementEvents": true,"DataResources": [{"Type":"AWS::S3::Object", "Values": ["arn:aws:s3:::amzn-s3-demo-bucket/prefix","arn:aws:s3:::amzn-s3-demo-bucket2/prefix2"]},{"Type": "AWS::Lambda::Function","Values": ["arn:aws:lambda:us-west-2:999999999999:function:hello-world-python-function"]}]}]'

The example returns the event selector configured for the trail.

{
    "EventSelectors": [
        {
            "ExcludeManagementEventSources": [],
            "IncludeManagementEvents": true,
            "DataResources": [
                {
                    "Values": [
                        "arn:aws:s3:::amzn-s3-demo-bucket/prefix",
                        "arn:aws:s3:::amzn-s3-demo-bucket2/prefix2"
                    ],
                    "Type": "AWS::S3::Object"
                },
                {
                    "Values": [
                        "arn:aws:lambda:us-west-2:123456789012:function:hello-world-python-function"
                    ],
                    "Type": "AWS::Lambda::Function"
                },
            ],
            "ReadWriteType": "All"
        }
    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

Example trail that logs all management and data events

The following example creates an event selector for a trail named TrailName2 that includes all management events, including read-only and write-only management events, and data events for all Amazon S3 buckets, AWS Lambda functions, and Amazon DynamoDB tables in the AWS account. Because this example uses basic event selectors, it cannot configure logging for S3 events on AWS Outposts, Amazon Managed Blockchain JSON-RPC calls on Ethereum nodes, or other advanced event selector resource types. You also can't log network activity events using basic event selectors. You must use advanced event selectors to log network activity events and data events for all other resource types. For more information, see Configuring advanced event selectors.

Note

If the trail applies only to one Region, only events in that Region are logged, even though the event selector parameters specify all Amazon S3 buckets and Lambda functions. Event selectors apply only to the Regions where the trail is created.

aws cloudtrail put-event-selectors --trail-name TrailName2 --event-selectors '[{"ReadWriteType": "All","IncludeManagementEvents": true,"DataResources": [{"Type":"AWS::S3::Object", "Values": ["arn:aws:s3:::"]},{"Type": "AWS::Lambda::Function","Values": ["arn:aws:lambda"]},{"Type": "AWS::DynamoDB::Table","Values": ["arn:aws:dynamodb"]}]}]'

The example returns the event selectors configured for the trail.

{
    "EventSelectors": [
        {
            "ExcludeManagementEventSources": [],
            "IncludeManagementEvents": true,
            "DataResources": [
                {
                    "Values": [
                        "arn:aws:s3:::"
                    ],
                    "Type": "AWS::S3::Object"
                },
                {
                    "Values": [
                        "arn:aws:lambda"
                    ],
                    "Type": "AWS::Lambda::Function"
                },
{
                    "Values": [
                        "arn:aws:dynamodb"
                    ],
                    "Type": "AWS::DynamoDB::Table"
                }
            ],
            "ReadWriteType": "All"
        }
    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName2"
}

Example trail that does not log AWS Key Management Service events

The following example creates an event selector for a trail named TrailName to include read-only and write-only management events, but to exclude AWS Key Management Service (AWS KMS) events. Because AWS KMS events are treated as management events, and there can be a high volume of them, they can have a substantial impact on your CloudTrail bill if you have more than one trail that captures management events. The user in this example has chosen to exclude AWS KMS events from every trail except for one. To exclude an event source, add ExcludeManagementEventSources to your event selectors, and specify an event source in the string value.

If you choose not to log management events, AWS KMS events are not logged, and you cannot change AWS KMS event logging settings.

To start logging AWS KMS events to a trail again, pass an empty array as the value of ExcludeManagementEventSources.

aws cloudtrail put-event-selectors --trail-name TrailName --event-selectors '[{"ReadWriteType": "All","ExcludeManagementEventSources": ["kms.amazonaws.com"],"IncludeManagementEvents": true]}]'

The example returns the event selector that is configured for the trail.

{
    "EventSelectors": [
        {
            "ExcludeManagementEventSources": [ "kms.amazonaws.com" ],
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "All"
        }
    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

To start logging AWS KMS events to a trail again, pass an empty array as the value of ExcludeManagementEventSources, as shown in the following command.

aws cloudtrail put-event-selectors --trail-name TrailName --event-selectors '[{"ReadWriteType": "All","ExcludeManagementEventSources": [],"IncludeManagementEvents": true]}]'

Example trail that logs relevant low-volume AWS Key Management Service events

The following example creates an event selector for a trail named TrailName to include write-only management events and AWS KMS events. Because AWS KMS events are treated as management events, and there can be a high volume of them, they can have a substantial impact on your CloudTrail bill if you have more than one trail that captures management events. The user in this example has chosen to include AWS KMS Write events, which will include Disable, Delete and ScheduleKey, but no longer include high-volume actions such as Encrypt, Decrypt, and GenerateDataKey (these are now treated as Read events).

aws cloudtrail put-event-selectors --trail-name TrailName --event-selectors '[{"ReadWriteType": "WriteOnly","ExcludeManagementEventSources": [],"IncludeManagementEvents": true]}]'

The example returns the event selector that is configured for the trail. This logs write-only management events, including AWS KMS events.

{
    "EventSelectors": [
        {
            "ExcludeManagementEventSources": [],
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "WriteOnly"
        }
    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

Example trail that does not log Amazon RDS data API events

The following example creates an event selector for a trail named TrailName to include read-only and write-only management events, but to exclude Amazon RDS Data API events. Because Amazon RDS Data API events are treated as management events, and there can be a high volume of them, they can have a substantial impact on your CloudTrail bill if you have more than one trail that captures management events. The user in this example has chosen to exclude Amazon RDS Data API events from every trail except for one. To exclude an event source, add ExcludeManagementEventSources to your event selectors, and specify the Amazon RDS Data API event source in the string value: rdsdata.amazonaws.com.

If you choose not to log management events, Amazon RDS Data API events are not logged, and you cannot change event logging settings.

To start logging Amazon RDS Data API management events to a trail again, pass an empty array as the value of ExcludeManagementEventSources.

aws cloudtrail put-event-selectors --trail-name TrailName --event-selectors '[{"ReadWriteType": "All","ExcludeManagementEventSources": ["rdsdata.amazonaws.com"],"IncludeManagementEvents": true]}]'

The example returns the event selector that is configured for the trail.

{
    "EventSelectors": [
        {
            "ExcludeManagementEventSources": [ "rdsdata.amazonaws.com" ],
            "IncludeManagementEvents": true,
            "DataResources": [],
            "ReadWriteType": "All"
        }
    ],
    "TrailARN": "arn:aws:cloudtrail:us-east-2:123456789012:trail/TrailName"
}

To start logging Amazon RDS Data API management events to a trail again, pass an empty array as the value of ExcludeManagementEventSources, as shown in the following command.

aws cloudtrail put-event-selectors --trail-name TrailName --event-selectors '[{"ReadWriteType": "All","ExcludeManagementEventSources": [],"IncludeManagementEvents": true]}]'

Stopping and starting logging for a trail

The following commands start and stop CloudTrail logging.

aws cloudtrail start-logging --name awscloudtrail-example
aws cloudtrail stop-logging --name awscloudtrail-example
Note

Before deleting a bucket, run the stop-logging command to stop delivering events to the bucket. If you don’t stop logging, CloudTrail attempts to deliver log files to a bucket with the same name for a limited period of time.

If you stop logging or delete a trail, CloudTrail Insights is disabled on that trail.

Deleting a trail

If you've enabled CloudTrail management events in Amazon Security Lake, you are required to maintain at least one organizational trail that is multi-Region and logs both read and write management events. You cannot delete a trail if it is the only trail you have that meets this requirement, unless you turn off CloudTrail management events in Security Lake.

You can delete a trail with the following command. You can delete a trail only in the Region it was created (the Home Region).

aws cloudtrail delete-trail --name awscloudtrail-example

When you delete a trail, you do not delete the Amazon S3 bucket or the Amazon SNS topic associated with it. Use the AWS Management Console, AWS CLI, or service API to delete these resources separately.
