Amazon Relational Database Service(RDS)는 클라우드에서 관계형 데이터베이스를 설정, 운영 및 확장하는 데 사용되는 웹 서비스입니다. 이 통합을 활성화하면 Datadog에서 모든 RDS 메트릭을 볼 수 있습니다.
참고: 환경 변수 DD_SITE
가 코드 외부의 리전 로 설정되었는지 확인하거나, 다음과 같이 코드에서 변수를 설정하세요:
DD_SITE = os.getenv("DD_SITE", default="
")
RDS 인스턴스를 모니터링하는 옵션에는 Standard, Enhanced, Native 세 가지가 있습니다. 각 메트릭에는 해당 설정이 라벨로 표시되어 있으므로 설정을 선택하기 전에 전체 메트릭 목록을 검토하세요. 또한 아래 정보를 검토하여 각 설정의 요구 사항 및 프리셋 대시보드에 대해 자세히 알아보세요:
표준 통합을 위해서는 AWS 통합 페이지의 Metric Collection
탭에서 RDS를 활성화해야 합니다. 이를 통해 클라우드와치(CloudWatch) 통합이 허용하는 한 인스턴스에 대한 메트릭을 자주 수신할 수 있습니다. 모든 RDS 엔진 유형이 지원됩니다.
이 통합을 위한 프리셋 대시보드에는 다음 메트릭 정보가 포함됩니다: 연결, 복제 지연, 읽기 작업 및 대기 시간, 컴퓨터, RAM, 쓰기 작업 및 대기 시간, 디스크 메트릭.
향상된 통합에는 추가 설정이 필요하며 MySQL, Aurora, MariaDB, SQL Server, Oracle 및 PostgreSQL 엔진에서 사용할 수 있습니다. 추가 메트릭을 사용할 수 있지만 메트릭을 Datadog에 제출하려면 AWS Lambda가 필요합니다. 더 높은 세분성 및 추가 필수 서비스로 인해 추가적인 AWS 요금이 발생할 수 있습니다.
이 통합을 위한 프리셋 대시보드에는 다음 메트릭 정보가 포함됩니다: 로드, 가동 시간, CPU 사용률, 작업, 메모리, SWAP, 네트워크 수신, 네트워크 전송, 프로세스당 사용된 CPU, 프로세스당 사용된 메모리, 디스크 작업, 사용된 파일 시스템(pct), 실행 중인 작업 및 시스템 CPU 사용률.
네이티브 데이터베이스 통합은 부수적이며 MySQL, Aurora, MariaDB, SQL Server 및 PostgreSQL 엔진 유형에 사용할 수 있습니다. RDS의 메트릭과 네이티브 통합의 메트릭을 일치시키려면, RDS 인스턴스에 할당한 식별자를 기반으로 네이티브 통합에서 dbinstanceidentifier
태그를 사용하세요. RDS 인스턴스에 자동으로 태그가 할당됩니다.
이 설정에 사용할 수 있는 3개의 프리셋 대시보드가 있습니다: MySQL, Aurora, PostgreSQL. 각 대시보드에는 다음 메트릭 정보가 포함됩니다: 쿼리 볼륨, 디스크 I/O, 연결, 복제 및 AWS 리소스 메트릭.
참고: 이 대시보드는 AWS 클라우드와치(CloudWatch)와 개별 데이터베이스 엔진 자체의 메트릭을 모두 표시합니다. 모든 통합 메트릭을 위해 MySQL, Aurora 또는 PostgreSQL 통합 중 하나를 활성화합니다.
표준 RDS 통합을 위해 먼저 Amazon Web Services 통합을 설정합니다.
Instance Actions에서 Modify를 선택하여 인스턴스 생성 중 또는 이후에 RDS 인스턴스에 대한 향상된 모니터링을 활성화합니다. Monitoring Granularity에 대해서는 15
를 권장합니다.
다음 지침에서는 KMS와 Lambda Management Console을 사용하여 RDS Enhanced Monitoring Lambda 함수에서만 사용할 수 있는 Datadog API 키의 암호화된 버전을 생성합니다. Log Forwarder와 같은 다른 Lambda의 암호화된 API 키가 이미 있는 경우 Lambda 함수의 README를 참조해 다른 옵션을 살펴보세요.
lambda-datadog-key
와 같은 키의 별칭을 입력합니다. 참고: 별칭은 aws로 시작할 수 없습니다. aws로 시작하는 별칭은 사용자의 계정에서 AWS 관리형 CMKs를 나타내기 위해 Amazon Web Services에서 예약한 것입니다.Serverless Application Repository
를 선택하고, Datadog-RDS-Enhanced
를 검색 후 선택하세요.KMSKeyId
파라미터의 이전 섹션에서 생성한 키의 Id를 붙여넣고 배포합니다.Configuration
탭을 클릭하고 Environment variables
섹션으로 이동합니다. 환경 변수 kmsEncryptedKeys
의 경우 다음과 같이 value
필드에 전체 JSON 형식의 Datadog API 키를 추가합니다. {"api_key":"<YOUR_API_KEY>"}
.Encryption configuration
섹션을 열고 Enable helpers for encryption in transit
을 선택합니다.KMS key to encrypt at rest
섹션에서 Use a customer master key
를 선택하고 앞서 생성한 동일한 KMS 키를 입력합니다.RDSOSMetrics
클라우드와치(CloudWatch) 로그 그룹을 소스로 사용하여 새 트리거를 생성합니다.Lambda 함수에 대한 테스트 버튼을 클릭하면 다음 오류가 발생할 수 있습니다:
{
"stackTrace": [
[
"/var/task/lambda_function.py",
109,
"lambda_handler",
"event = json.loads(gzip.GzipFile(fileobj=StringIO(event['awslogs']['data'].decode('base64'))).read())"
]
],
"errorType": "KeyError",
"errorMessage": "'awslogs'"
}
이것은 무시해도 됩니다. 이 설정에서는 테스트 버튼이 작동하지 않습니다.
AWS 콘솔로 이동하고 RDS 섹션을 열어 모니터링하려는 인스턴스를 찾습니다.
예를 들어 mysqlrds.blah.us-east1.rds.amazonaws.com:3306과 같은 Agent를 설정하는 데 사용되는 엔드포인트 URL을 기록해 두세요. mysqlrds와 같은 DB Instance identifier
도 기록해 둡니다. 이는 그래프와 대시보드를 만드는 데 사용됩니다.
AWS 통합 페이지에서 Metric Collection
탭 아래에 RDS
가 활성화되어 있는지 확인합니다.
Amazon RDS 메트릭을 수집하려면 Datadog IAM 정책에 다음 권한을 추가하세요. 자세한 내용은 AWS 웹사이트에서 RDS 정책을 참조하세요.
AWS 권한 | 설명 |

conf.d 디렉토리에서 적절한 yaml 파일을 편집하여 Agent를 설정하고 RDS 인스턴스에 연결한 다음 Agent를 다시 시작하세요:
RDS Aurora의 경우, 사용 중인 데이터베이스 플레이버의 YAML 파일을 편집합니다.
MySQL 또는 MariaDB를 사용하는 경우 mysql.yaml
을 편집합니다:
init_config:
instances:
# AWS 콘솔의 엔드포인트 URL
- server: 'mysqlrds.blah.us-east-1.rds.amazonaws.com'
user: '<USERNAME>'
pass: '<PASSWORD>'
port: 3306
tags:
- 'dbinstanceidentifier:<INSTANCE_NAME>'
PostgreSQL을 사용하는 경우 postgres.yaml
을 편집합니다:
init_config:
instances:
- host: 'postgresqlrds.blah.us-east-1.rds.amazonaws.com'
port: 5432
username: '<USERNAME>'
password: '<PASSWORD>'
dbname: '<DB_NAME>'
tags:

Microsoft SQL Server를 사용하는 경우 sqlserver.yaml
를 편집합니다:
init_config:
instances:
- host: 'sqlserverrds.blah.us-east-1.rds.amazonaws.com,1433'
username: '<USERNAME>'
password: '<PASSWORD>'

몇 분 후, RDS 메트릭 및 MySQL, Aurora, MariaDB, SQL Server, Oracle 또는 PostgreSQL의 메트릭은 Datadog의 메트릭 탐색기, 대시보드 및 알림에서 액세스할 수 있습니다.
다음은 RDS와 MySQL 통합의 여러 메트릭을 표시하는 Aurora 대시보드의 예입니다. 인스턴스 quicktestrds
에 대한 두 통합의 메트릭은 dbinstanceidentifier
태그를 사용하여 통합됩니다.
MySQL, MariaDB 및 Postgres 로그를 Amazon 클라우드와치(CloudWatch)로 전달할 수 있습니다. Amazon CloudWatch로 Amazon Aurora MySQL, MySQL용 Amazon RDS 및 MariaDB 로그 모니터링에 있는지침에 따라 클라우드와치(CloudWatch)로 RDS 로그 전송을 시작하세요.
완료되면, Datadog Log 섹션으로 이동하여 로그를 탐색합니다.
