![MongoDB 대시보드1
MongoDB를 Datadog에 연결하면 다음을 수행할 수 있습니다.
커스텀 find
, count
, aggregate
쿼리를 사용하여 고유한 메트릭을 만들 수도 있습니다.
데이터베이스 모니터링(DBM)을 통해 쿼리 성능 및 데이터베이스 상태에 대한 인사이트를 얻을 수 있습니다. 표준 통합 외에도 Datadog DBM은 실시간 및 이전 쿼리 스냅샷, 느린 쿼리 메트릭, 데이터베이스 로드, 작업 실행 계획 및 컬렉션 인사이트를 제공합니다.
참고: 이 통합에는 MongoDB v3.0 이상이 필요합니다. MongoDB Atlas와 Datadog의 통합은 M10 이상 클러스터에서만 사용할 수 있습니다. 이 통합은 Alibaba ApsaraDB 및 AWS DocumentDB 인스턴스 기반 클러스터도 지원합니다. DocumentDB Elastic 클러스터는 클러스터(mongos) 엔드포인트만 노출하므로 지원되지 않습니다.
MongoDB 점검은 Datadog Agent 패키지에 포함되어 있어 추가 설치가 필요하지 않습니다.
참고: MongoDB용 데이터베이스 모니터링을 설치하려면 데이터베이스 모니터링 문서에서 해당 호스팅 솔루션을 선택한 후 지침을 확인하세요.
대부분의 하위 수준 메트릭(가동 시간, 스토리지 크기 등)은 모든 mongod 노드에서 수집되어야 합니다. 기타 상위 수준 메트릭(컬렉션/인덱스 통계 등)는 한 번만 수집해야 합니다. 이러한 이유로 Agent를 구성하는 방법은 mongo 클러스터 배포 방법에 따라 달라집니다.
단일 노드 MongoDB 배포에 대해 이 통합을 구성하려면 다음 지침을 따르세요.
Mongo 셸에서 admin
데이터베이스의 Datadog Agent에 대한 읽기 전용 사용자를 만듭니다.
# 어드민 사용자로 인증합니다.
use admin
db.auth("admin", "<YOUR_MONGODB_ADMIN_PASSWORD>")
# Datadog Agent에 대한 사용자를 만듭니다.
db.createUser({
"user": "datadog",
"pwd": "<UNIQUEPASSWORD>",
"roles": [
{ role: "read", db: "admin" },
{ role: "clusterMonitor", db: "admin" },
{ role: "read", db: "local" },
#컬렉션/인덱스 통계를 수집하려는 데이터베이스에 대한 추가 읽기 전용 액세스 권한을 부여합니다.
{ role: "read", db: "mydb" },
{ role: "read", db: "myanotherdb" },
# 또는 모든 데이터베이스에 읽기 전용 액세스 권한을 부여합니다.
{ role: "readAnyDatabase", db: "admin" }
]
})
사용 가능한 모든 mongo 메트릭을 수집하려면 단일 Agent(가급적이면 동일한 노드에서 실행)만 필요합니다. 구성 옵션은 아래를 참조하세요.
MongoDB 복제본 세트에 대해 이 통합을 구성하려면 다음 지침을 따르세요.
Mongo 셸에서 기본 인증 후 admin
데이터베이스의 Datadog Agent에 대한 읽기 전용 사용자를 만듭니다.
# 어드민 사용자로 인증합니다.
use admin
db.auth("admin", "<YOUR_MONGODB_ADMIN_PASSWORD>")
# Datadog Agent에 대한 사용자를 만듭니다.
db.createUser({
"user": "datadog",
"pwd": "<UNIQUEPASSWORD>",
"roles": [
{ role: "read", db: "admin" },
{ role: "clusterMonitor", db: "admin" },
{ role: "read", db: "local" },
# 컬렉션/인덱스 통계를 수집하려는 데이터베이스에 대한 추가 읽기 전용 액세스 권한을 부여합니다.
{ role: "read", db: "mydb" },
{ role: "read", db: "myanotherdb" },
# 또는 모든 데이터베이스에 읽기 전용 액세스 권한을 부여합니다.
{ role: "readAnyDatabase", db: "admin" }
]
})
MongoDB 복제본 세트의 각 호스트에 Datadog Agent를 설치하고 해당 호스트(localhost
)의 복제본에 연결하도록 Agent를 구성합니다. 각 호스트에서 Agent를 실행하면 대기 시간과 실행 시간이 줄어들고 호스트에 장애가 발생하더라도 데이터가 계속 연결되어 있습니다.
예를 들어 기본 노드에서 다음을 수행합니다.
init_config:
instances:
- hosts:
- mongo-primary:27017
2차 노드에서 다음을 수행합니다.
init_config:
instances:
- hosts:
- mongo-secondary:27017
3차 노드에서 다음을 수행합니다.
init_config:
instances:
- hosts:
- mongo-tertiary:27017
MongoDB 샤드 클러스터에 대해 이 통합을 구성하려면 다음 지침을 따르세요.
클러스터의 각 샤드에 대해 복제본 세트의 기본 샤드에 연결하고 admin
데이터베이스의 Datadog Agent에 대한 로컬 읽기 전용 사용자를 생성합니다.
# 어드민 사용자로 인증합니다.
use admin
db.auth("admin", "<YOUR_MONGODB_ADMIN_PASSWORD>")
# Datadog Agent에 대한 사용자를 만듭니다.
db.createUser({
"user": "datadog",
"pwd": "<UNIQUEPASSWORD>",
"roles": [
{ role: "read", db: "admin" },
{ role: "clusterMonitor", db: "admin" },
{ role: "read", db: "local" }
]
})
그런 다음 mongos 프록시에서 동일한 사용자를 만듭니다. 이 작업을 수행하면 구성 서버에 로컬 사용자가 생성되고 직접 연결이 허용됩니다.
참고: 중재자 노드 모니터링은 지원되지 않습니다(자세한 내용은 MongoDB Replica Set Arbiter 참조). 그러나 기본 노드에 연결된 Agent가 중재자 노드의 상태 변경을 보고합니다.
호스트에서 실행되는 경우 아래 지침에 따라 이 점검을 설정하세요. 컨테이너화된 환경 경우 도커(Docker), 쿠버네티스(Kubernetes) 또는 ECS 섹션을 참조하세요.
호스트에서 실행 중인 에이전트에 이 점검을 구성하는 방법:
