describe-trails¶

Description¶

Retrieves settings for one or more trails associated with the current region for your account.

Synopsis¶

  describe-trails
[--trail-name-list <value>]
[--include-shadow-trails | --no-include-shadow-trails]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--trail-name-list (list)

Specifies a list of trail names, trail ARNs, or both, of the trails to describe. The format of a trail ARN is:

arn:aws:cloudtrail:us-east-2:123456789012:trail/MyTrail

If an empty list is specified, information for the trail in the current region is returned.

If an empty list is specified and IncludeShadowTrails is false, then information for all trails in the current region is returned.

If an empty list is specified and IncludeShadowTrails is null or true, then information for all trails in the current region and any associated shadow trails in other regions is returned.

Note

If one or more trail names are specified, information is returned only if the names match the names of trails belonging only to the current region. To return information about a trail in another region, you must specify its trail ARN.

(string)

Syntax:

"string" "string" ...

--include-shadow-trails | --no-include-shadow-trails (boolean)

Specifies whether to include shadow trails in the response. A shadow trail is the replication in a region of a trail that was created in a different region, or in the case of an organization trail, the replication of an organization trail in member accounts. If you do not include shadow trails, organization trails in a member account and region replication trails will not be returned. The default is true.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To describe a trail

The following describe-trails command returns the settings for Trail1 and Trail2:

aws cloudtrail describe-trails --trail-name-list Trail1 Trail2

Output:

trailList -> (list)

The list of trail objects. Trail objects with string values are only returned if values for the objects exist in a trail’s configuration. For example, SNSTopicName and SNSTopicARN are only returned in results if a trail is configured to send SNS notifications. Similarly, KMSKeyId only appears in results if a trail’s log files are encrypted with KMS customer managed keys.
