Utilizzo della ricerca delle transazioni con AWS CloudFormation

È possibile utilizzare AWS CloudFormation per abilitare e configurare X-Ray Transaction Search.

Prerequisiti

Attivazione della ricerca nelle transazioni

Per abilitare l'utilizzo di Transaction Search CloudFormation, è necessario creare le due risorse seguenti.

Esempi di modelli

L'esempio seguente include sia la politica delle risorse che il TransactionSearchConfig.

YAML

Resources:
  LogsResourcePolicy:
    Type: AWS::Logs::ResourcePolicy
    Properties:
      PolicyName: TransactionSearchAccess
      PolicyDocument: !Sub >
        {
          "Version": "2012-10-17",
          "Statement": [
            {
              "Sid": "TransactionSearchXRayAccess",
              "Effect": "Allow",
              "Principal": {
                "Service": "xray.amazonaws.com"
              },
              "Action": "logs:PutLogEvents",
              "Resource": [
                "arn:${AWS::Partition}:logs:${AWS::Region}:${AWS::AccountId}:log-group:aws/spans:*",
                "arn:${AWS::Partition}:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/application-signals/data:*"
              ],
              "Condition": {
                "ArnLike": {
                  "aws:SourceArn": "arn:${AWS::Partition}:xray:${AWS::Region}:${AWS::AccountId}:*"
                },
                "StringEquals": {
                  "aws:SourceAccount": "${AWS::AccountId}"
                }
              }
            }
          ]
        }

  XRayTransactionSearchConfig:
    Type: AWS::XRay::TransactionSearchConfig
    Properties:
      IndexingPercentage: 10

JSON

{
    "Resources": {
        "LogsResourcePolicy": {
            "Type": "AWS::Logs::ResourcePolicy",
            "Properties": {
                "PolicyName": "TransactionSearchAccess",
                "PolicyDocument": {
                    "Fn::Sub": "{\n  \"Version\": \"2012-10-17\",\n  \"Statement\": [\n    {\n      \"Sid\": \"TransactionSearchXRayAccess\",\n      \"Effect\": \"Allow\",\n      \"Principal\": {\n        \"Service\": \"xray.amazonaws.com\"\n      },\n      \"Action\": \"logs:PutLogEvents\",\n      \"Resource\": [\n        \"arn:${AWS::Partition}:logs:${AWS::Region}:${AWS::AccountId}:log-group:aws/spans:*\",\n        \"arn:${AWS::Partition}:logs:${AWS::Region}:${AWS::AccountId}:log-group:/aws/application-signals/data:*\"\n      ],\n      \"Condition\": {\n        \"ArnLike\": {\n          \"aws:SourceArn\": \"arn:${AWS::Partition}:xray:${AWS::Region}:${AWS::AccountId}:*\"\n        },\n        \"StringEquals\": {\n          \"aws:SourceAccount\": \"${AWS::AccountId}\"\n        }\n      }\n    }\n  ]\n}"
                }
            }
        },
        "XRayTransactionSearchConfig": {
            "Type": "AWS::XRay::TransactionSearchConfig",
            "Properties": {
                "IndexingPercentage": 20
            }
        }
    }
}

Ecco un esempio di utilizzo di AWS CDK in TypeScript.

CDK

import * as cdk from '@aws-cdk/core';
import * as logs from '@aws-cdk/aws-logs';
import * as xray from '@aws-cdk/aws-xray';

export class XRayTransactionSearchStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // Create the resource policy
    const transactionSearchAccess = new logs.CfnResourcePolicy(this, 'XRayLogResourcePolicy', {
      policyName: 'TransactionSearchAccess',
      policyDocument: JSON.stringify({
        Version: '2012-10-17',
        Statement: [
          {
            Sid: 'TransactionSearchXRayAccess',
            Effect: 'Allow',
            Principal: {
              Service: 'xray.amazonaws.com',
            },
            Action: 'logs:PutLogEvents',
            Resource: [
              `arn:${this.partition}:logs:${this.region}:${this.account}:log-group:aws/spans:*`,
              `arn:${this.partition}:logs:${this.region}:${this.account}:log-group:/aws/application-signals/data:*`,
            ],
            Condition: {
              ArnLike: {
                'aws:SourceArn': `arn:${this.partition}:xray:${this.region}:${this.account}:*`,
              },
              StringEquals: {
                'aws:SourceAccount': this.account,
              },
            },
          },
        ],
      }),
    });

    // Create the TransactionSearchConfig with dependency
    const transactionSearchConfig = new xray.CfnTransactionSearchConfig(this, 'XRayTransactionSearchConfig', {
      indexingPercentage: 10,
    });

    // Add the dependency to ensure Resource Policy is created first
    transactionSearchConfig.addDependsOn(transactionSearchAccess);
  }
} 
        
      

Verifica della configurazione

Dopo aver distribuito lo AWS CloudFormation stack, puoi verificare la configurazione utilizzando. AWS CLI

aws xray get-trace-segment-destination

Una configurazione corretta restituirà quanto segue.

{
    "Destination": "CloudWatchLogs",
    "Status": "ACTIVE"
}
