Uso de Transaction Search con AWS CloudFormation

Puede utilizar AWS CloudFormation para habilitar y configurar X-Ray Transaction Search.

nota

Para crear una pila de AWS CloudFormation, consulte Creación de su primera pila.

  • Debe tener acceso a una cuenta de AWS con un rol o usuario de IAM que tenga permisos para usar Amazon EC2, Amazon S3, AWS CloudFormation o acceso de usuario administrativo.

  • Debe tener una nube privada virtual (VPC) que tenga acceso a Internet. Para simplificar, puede usar la VPC predeterminada que se incluye con su cuenta. La VPC predeterminada y las subredes predeterminadas bastan para esta configuración.

  • Asegúrese de que Transaction Search esté deshabilitada antes de habilitarla usando AWS CDK o AWS CloudFormation.

Habilitación de Transaction Search

Para habilitar Transaction Search mediante CloudFormation, debe crear los siguientes dos recursos.

  • AWS::Logs::ResourcePolicy

  • AWS::XRay::TransactionSearchConfig

  1. Crear AWS::Logs::ResourcePolicy: cree una política de recursos que permita a X-Ray enviar rastros a los registros de CloudWatch

    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}"
                }
              }
            }
          ]
        }

    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}"
                }
            }
        }
    }
}

  2. Crear y configurar AWS::XRay::TransactionSearchConfig: cree el recurso TransactionSearchConfig para habilitar Transaction Search.

    YAML

    Resources:
  XRayTransactionSearchConfig:
    Type: AWS::XRay::TransactionSearchConfig

    JSON

    {
  "Resources": {
    "XRayTransactionSearchConfig": {
      "Type": "AWS::XRay::TransactionSearchConfig"
    }
  }
}

  3. (Opcional) Puede configurar la propiedad IndexingPercentage para controlar el porcentaje de intervalos que se indexarán.

    YAML

    Resources:
  XRayTransactionSearchConfig:
    Type: AWS::XRay::TransactionSearchConfig
    Properties:
      IndexingPercentage: 50

    JSON

    {
  "Resources": {
    "XRayTransactionSearchConfig": {
      "Type": "AWS::XRay::TransactionSearchConfig",
      "Properties": {
        "IndexingPercentage": 20
      }
    }
  }
}

    El valor de IndexingPercentage se puede establecer entre 0 y 100.

Ejemplos de plantillas

El siguiente ejemplo incluye tanto la política de recursos como la 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
            }
        }
    }
}

A continuación se muestra un ejemplo usando AWS CDK en 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);
  }
}

Verificación de la configuración

Después de implementar su pila de AWS CloudFormation, puede verificar la configuración mediante la AWS CLI.

aws xray get-trace-segment-destination

Una configuración correcta devolverá lo siguiente.

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