[ aws . cloudtrail ]



Looks up management events or CloudTrail Insights events that are captured by CloudTrail. You can look up events that occurred in a Region within the last 90 days.


LookupEvents returns recent Insights events for trails that enable Insights. To view Insights events for an event data store, you can run queries on your Insights event data store, and you can also view the Lake dashboard for Insights.

Lookup supports the following attributes for management events:

  • Amazon Web Services access key
  • Event ID
  • Event name
  • Event source
  • Read only
  • Resource name
  • Resource type
  • User name

Lookup supports the following attributes for Insights events:

  • Event ID
  • Event name
  • Event source

All attributes are optional. The default number of results returned is 50, with a maximum of 50 possible. The response includes a token that you can use to get the next page of results.


The rate of lookup requests is limited to two per second, per account, per Region. If this limit is exceeded, a throttling error occurs.

See also: AWS API Documentation

lookup-events is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Events


[--lookup-attributes <value>]
[--start-time <value>]
[--end-time <value>]
[--event-category <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--endpoint-url <value>]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]


--lookup-attributes (list)

Contains a list of lookup attributes. Currently the list can contain only one item.


Specifies an attribute and value that filter the events returned.

AttributeKey -> (string)

Specifies an attribute on which to filter the events returned.

AttributeValue -> (string)

Specifies a value for the specified AttributeKey .

The maximum length for the AttributeValue is 2000 characters. The following characters ('_ ', '```` ', ', ', '\\n ') count as two characters towards the 2000 character limit.

Shorthand Syntax:

AttributeKey=string,AttributeValue=string ...

JSON Syntax:

    "AttributeKey": "EventId"|"EventName"|"ReadOnly"|"Username"|"ResourceType"|"ResourceName"|"EventSource"|"AccessKeyId",
    "AttributeValue": "string"

--start-time (timestamp)

Specifies that only events that occur after or at the specified time are returned. If the specified start time is after the specified end time, an error is returned.

--end-time (timestamp)

Specifies that only events that occur before or at the specified time are returned. If the specified end time is before the specified start time, an error is returned.

--event-category (string)

Specifies the event category. If you do not specify an event category, events of the category are not returned in the response. For example, if you do not specify insight as the value of EventCategory , no Insights events are returned.

Possible values:

  • insight

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To look up events for a trail

The following lookup-events command looks up API activity events by the attribute EventName:

aws cloudtrail lookup-events --lookup-attributes AttributeKey=EventName,AttributeValue=ConsoleLogin

Events -> (list)

A list of events returned based on the lookup attributes specified and the CloudTrail event. The events list is sorted by time. The most recent event is listed first.


Contains information about an event that was returned by a lookup request. The result includes a representation of a CloudTrail event.

EventId -> (string)

The CloudTrail ID of the event returned.

EventName -> (string)

The name of the event returned.

ReadOnly -> (string)

Information about whether the event is a write event or a read event.

AccessKeyId -> (string)

The Amazon Web Services access key ID that was used to sign the request. If the request was made with temporary security credentials, this is the access key ID of the temporary credentials.

EventTime -> (timestamp)

The date and time of the event returned.

EventSource -> (string)

The Amazon Web Services service to which the request was made.

Username -> (string)

A user name or role name of the requester that called the API in the event returned.

Resources -> (list)

A list of resources referenced by the event returned.


Specifies the type and name of a resource referenced by an event.

ResourceType -> (string)

The type of a resource referenced by the event returned. When the resource type cannot be determined, null is returned. Some examples of resource types are: Instance for EC2, Trail for CloudTrail, DBInstance for Amazon RDS, and AccessKey for IAM. To learn more about how to look up and filter events by the resource types supported for a service, see Filtering CloudTrail Events .

ResourceName -> (string)

The name of the resource referenced by the event returned. These are user-created names whose values will depend on the environment. For example, the resource name might be "auto-scaling-test-group" for an Auto Scaling Group or "i-1234567" for an EC2 Instance.

CloudTrailEvent -> (string)

A JSON string that contains a representation of the event returned.

NextToken -> (string)

The token to use to get the next page of results after a previous API call. If the token does not appear, there are no more results to return. The token must be passed in with the same parameters as the previous call. For example, if the original call specified an AttributeKey of 'Username' with a value of 'root', the call with NextToken should include those same parameters.
