Description

Note

This is the latest version of AWS WAF , named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Provides high-level information for a managed rule group, including descriptions of the rules.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  describe-managed-rule-group
--vendor-name <value>
--name <value>
--scope <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--vendor-name (string)

The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.

--name (string)

The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.

--scope (string)

Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

  • CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
  • API and SDKs - For all calls, use the Region endpoint us-east-1.

Possible values:

  • CLOUDFRONT
  • REGIONAL

--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.

--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.

See 'aws help' for descriptions of global parameters.

Output

Capacity -> (long)

The web ACL capacity units (WCUs) required for this rule group. AWS WAF uses web ACL capacity units (WCU) to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect each rule's relative cost. Rule group capacity is fixed at creation, so users can plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

Rules -> (list)
