create-sampling-rule

Description

Creates a rule to control sampling behavior for instrumented applications. Services retrieve rules with GetSamplingRules , and evaluate each rule in ascending order of priority for each request. If a rule matches, the service records a trace, borrowing it from the reservoir size. After 10 seconds, the service reports back to X-Ray with GetSamplingTargets to get updated versions of each in-use rule. The updated rule contains a trace quota that the service can use instead of borrowing from the reservoir.

Options

--sampling-rule (structure)

The rule definition.

RuleName -> (string)

The name of the sampling rule. Specify a rule by either name or ARN, but not both.

RuleARN -> (string)

FixedRate -> (double)

The percentage of matching requests to instrument, after the reservoir is exhausted.

--tags (list)

A map that contains one or more tag keys and tag values to attach to an X-Ray sampling rule. For more information about ways to use tags, see Tagging Amazon Web Services resources in the Amazon Web Services General Reference .

The following restrictions apply to tags:

  • Maximum number of user-applied tags per resource: 50

  • Maximum tag key length: 128 Unicode characters

  • Maximum tag value length: 256 Unicode characters

  • Valid values for key and value: a-z, A-Z, 0-9, space, and the following characters: _ . : / = + - and @

  • Tag keys and values are case sensitive.

  • Don’t use aws: as a prefix for keys; it’s reserved for Amazon Web Services use.

(structure)

A map that contains tag keys and tag values to attach to an Amazon Web Services X-Ray group or sampling rule. For more information about ways to use tags, see Tagging Amazon Web Services resources in the Amazon Web Services General Reference .

The following restrictions apply to tags:

  • Maximum number of user-applied tags per resource: 50

  • Tag keys and values are case sensitive.

  • Don’t use aws: as a prefix for keys; it’s reserved for Amazon Web Services use. You cannot edit or delete system tags.

Key -> (string)

A tag key, such as Stage or Name . A tag key cannot be empty. The key can be a maximum of 128 characters, and can contain only Unicode letters, numbers, or separators, or the following special characters: + - = . _ : /

Value -> (string)

An optional tag value, such as Production or test-only . The value can be a maximum of 255 characters, and contain only Unicode letters, numbers, or separators, or the following special characters: + - = . _ : /

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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

  • yaml

  • yaml-stream

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

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 create a sampling rule

The following create-sampling-rule example creates a rule to control sampling behavior for instrumented applications. The rules are provided by a JSON file. The majority of the sampling rule fields are required to create the rule.

aws xray create-sampling-rule \
    --cli-input-json file://9000-base-scorekeep.json

Contents of 9000-base-scorekeep.json:

{
    "SamplingRule": {
        "RuleName": "base-scorekeep",
        "ResourceARN": "*",

        "FixedRate": 0.1,
        "ReservoirSize": 5,

        "Host": "*",
        "HTTPMethod": "*",
        "URLPath": "*",

    }
}

Output:

            "URLPath": "*",
            "Version": 1,
            "Attributes": {}
        },
