Utilizzo CreateSamplingRule con un AWS SDK o una CLI

Come creare una regola di campionamento

L’esempio create-sampling-rule seguente crea una regola per controllare il comportamento di campionamento delle applicazioni strumentate. Le regole sono fornite da un file JSON. La maggior parte dei campi delle regole di campionamento è necessaria per creare la regola.

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

Contenuto di 9000-base-scorekeep.json:

{
    "SamplingRule": {
        "RuleName": "base-scorekeep",
        "ResourceARN": "*",
        "Priority": 9000,
        "FixedRate": 0.1,
        "ReservoirSize": 5,
        "ServiceName": "Scorekeep",
        "ServiceType": "*",
        "Host": "*",
        "HTTPMethod": "*",
        "URLPath": "*",
        "Version": 1
    }
}

Output:

{
    "SamplingRuleRecord": {
        "SamplingRule": {
            "RuleName": "base-scorekeep",
            "RuleARN": "arn:aws:xray:us-west-2:123456789012:sampling-rule/base-scorekeep",
            "ResourceARN": "*",
            "Priority": 9000,
            "FixedRate": 0.1,
            "ReservoirSize": 5,
            "ServiceName": "Scorekeep",
            "ServiceType": "*",
            "Host": "*",
            "HTTPMethod": "*",
            "URLPath": "*",
            "Version": 1,
            "Attributes": {}
        },
        "CreatedAt": 1530574410.0,
        "ModifiedAt": 1530574410.0
    }
}
