给aws xray添加采样规则

准备规则文件

rule-apigateway-dev-10pct.json

json 复制代码

{
  "SamplingRule": {
    "RuleName": "apigateway-prod-10pct",
    "ResourceARN": "*",
    "Priority": 100,
    "FixedRate": 0.1,
    "ReservoirSize": 0,
    "ServiceName": "*",
    "ServiceType": "*",
    "Host": "*",
    "HTTPMethod": "*",
    "URLPath": "/prod/*",
    "Version": 1,
    "Attributes": {}
  }
}

新增规则不会改变 Default，它仍然是 FixedRate=0.05、ReservoirSize=1。只有命中 /prod/* 的请求才会按 10% 采样。

添加采样规则

bash 复制代码

aws xray create-sampling-rule --region cn-north-1 --cli-input-json file://rule-apigateway-dev-10pct.json

查看所有规则

bash 复制代码

aws xray get-sampling-rules
