get-sampled-requests¶

Description¶

Note

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Gets detailed information about a specified number of requests–a sample–that AWS WAF randomly selects from among the first 5,000 requests that your AWS resource received during a time range that you choose. You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.

GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which AWS WAF selected the requests in the sample.

Synopsis¶

  get-sampled-requests
--web-acl-id <value>
--rule-id <value>
--time-window <value>
--max-items <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--web-acl-id (string)

The WebACLId of the WebACL for which you want GetSampledRequests to return a sample of requests.

--rule-id (string)

RuleId is one of three values:

The RuleId of the Rule or the RuleGroupId of the RuleGroup for which you want GetSampledRequests to return a sample of requests.

Default_Action , which causes GetSampledRequests to return a sample of the requests that didn’t match any of the rules in the specified WebACL .

--time-window (structure)

The start date and time and the end date and time of the range for which you want GetSampledRequests to return a sample of requests. You must specify the times in Coordinated Universal Time (UTC) format. UTC format includes the special designator, Z . For example, "2016-09-27T14:50Z" . You can specify any time range in the previous three hours.

StartTime -> (timestamp)

The beginning of the time range from which you want GetSampledRequests to return a sample of the requests that your AWS resource received. You must specify the date and time in Coordinated Universal Time (UTC) format. UTC format includes the special designator, Z . For example, "2016-09-27T14:50Z" . You can specify any time range in the previous three hours.

EndTime -> (timestamp)

The end of the time range from which you want GetSampledRequests to return a sample of the requests that your AWS resource received. You must specify the date and time in Coordinated Universal Time (UTC) format. UTC format includes the special designator, Z . For example, "2016-09-27T14:50Z" . You can specify any time range in the previous three hours.

Shorthand Syntax:

StartTime=timestamp,EndTime=timestamp

JSON Syntax:

{
  "StartTime": timestamp,
  "EndTime": timestamp
}

--max-items (long)

The number of requests that you want AWS WAF to return from among the first 5,000 requests that your AWS resource received during the time range. If your resource received fewer requests than the value of MaxItems , GetSampledRequests returns information about all of them.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Output¶

SampledRequests -> (list)

A complex type that contains detailed information about each of the requests in the sample.

(structure)

Note

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

The response from a GetSampledRequests request includes a SampledHTTPRequests complex type that appears as SampledRequests in the response syntax. SampledHTTPRequests contains one SampledHTTPRequest object for each web request that is returned by GetSampledRequests .

Request -> (structure)

A complex type that contains detailed information about the request.

ClientIP -> (string)

The IP address that the request originated from. If the WebACL is associated with a CloudFront distribution, this is the value of one of the following fields in CloudFront access logs:

c-ip , if the viewer did not use an HTTP proxy or a load balancer to send the request

x-forwarded-for , if the viewer did use an HTTP proxy or a load balancer to send the request

Country -> (string)

The two-letter country code for the country that the request originated from. For a current list of country codes, see the Wikipedia entry ISO 3166-1 alpha-2 .

URI -> (string)

The part of a web request that identifies the resource, for example, /images/daily-ad.jpg .

Method -> (string)

The HTTP method specified in the sampled web request. CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .

HTTPVersion -> (string)

The HTTP version specified in the sampled web request, for example, HTTP/1.1 .

Headers -> (list)

A complex type that contains two values for each header in the sampled web request: the name of the header and the value of the header.

(structure)

Note

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

The response from a GetSampledRequests request includes an HTTPHeader complex type that appears as Headers in the response syntax. HTTPHeader contains the names and values of all of the headers that appear in one of the web requests that were returned by GetSampledRequests .

Name -> (string)

The name of one of the headers in the sampled web request.

Value -> (string)

The value of one of the headers in the sampled web request.

Weight -> (long)

A value that indicates how one result in the response relates proportionally to other results in the response. A result that has a weight of 2 represents roughly twice as many CloudFront web requests as a result that has a weight of 1 .

Timestamp -> (timestamp)

The time at which AWS WAF received the request from your AWS resource, in Unix time format (in seconds).

Action -> (string)

The action for the Rule that the request matched: ALLOW , BLOCK , or COUNT .

RuleWithinRuleGroup -> (string)

This value is returned if the GetSampledRequests request specifies the ID of a RuleGroup rather than the ID of an individual rule. RuleWithinRuleGroup is the rule within the specified RuleGroup that matched the request listed in the response.

PopulationSize -> (long)

The total number of requests from which GetSampledRequests got a sample of MaxItems requests. If PopulationSize is less than MaxItems , the sample includes every request that your AWS resource received during the specified time range.

TimeWindow -> (structure)

Usually, TimeWindow is the time range that you specified in the GetSampledRequests request. However, if your AWS resource received more than 5,000 requests during the time range that you specified in the request, GetSampledRequests returns the time range for the first 5,000 requests. Times are in Coordinated Universal Time (UTC) format.

StartTime -> (timestamp)

The beginning of the time range from which you want GetSampledRequests to return a sample of the requests that your AWS resource received. You must specify the date and time in Coordinated Universal Time (UTC) format. UTC format includes the special designator, Z . For example, "2016-09-27T14:50Z" . You can specify any time range in the previous three hours.

EndTime -> (timestamp)

The end of the time range from which you want GetSampledRequests to return a sample of the requests that your AWS resource received. You must specify the date and time in Coordinated Universal Time (UTC) format. UTC format includes the special designator, Z . For example, "2016-09-27T14:50Z" . You can specify any time range in the previous three hours.
