CoreDNS

Supported OS Linux

통합 버전3.2.2

개요

실시간으로 CoreDNS에서 메트릭을 받아 DNS 실패와 캐시 적중 및 캐시 누락을 가시화 및 모니터링하세요.

설정

버전 1.11.0부터 본 OpenMetrics 기반 통합에는 최신 모드(openmetrics_endpoint가 대상 엔드포인트를 가리키도록 설정하여 활성화됨)와 레거시 모드(prometheus_url를 대신 설정하여 활성화됨)가 있습니다. Datadog에서는 최신 모드를 활성화해 최신 기능을 사용할 것을 권장합니다. 자세한 내용을 확인하려면 OpenMetrics 기반 통합의 최신 및 레거시 버전 관리를 참고하세요.

CoreDNS 점검 최신 모드를 사용하려면 Python 3이 필요하며 .bucket 메트릭을 제출하고 .sum 및 .count 히스토그램 샘플을 단조 카운트 유형으로 제출합니다. 이전에는 이 메트릭이 레거시 모드에서 gauge 유형으로 제출되었습니다. 각 모드에서 사용할 수 있는 메트릭 목록은 metadata.csv 파일을 참고하세요.

Python 3을 사용할 수 없는 호스트나 이 통합 모드를 전에 구현한 적이 있으면 legacy 모드 구성 예시를 참고하세요. coredns.d/auto_conf.yaml 파일을 사용하는 자동탐지 사용자의 경우, 이 파일은 기본적으로 점검 legacy 모드에서 prometheus_url 옵션을 활성화합니다. 기본 구성 옵션을 보려면 coredns.d/auto_conf.yaml 샘플을 보고 사용할 수 있는 구성 옵션 목록 전체를 보려면 coredns.d/conf.yaml.example 샘플을 보세요.

설치

Datadog 에이전트 패키지에 CoreDNS 점검이 포함되어 있기 때문에 서버에 새로운 설치를 할 필요가 없습니다.

설정

    Docker

    컨테이너에서 실행 중인 에이전트에 이 점검을 구성하는 방법:

    메트릭 수집

    애플리케이션 컨테이너에서 자동탐지 통합 템플릿을 Docker 레이블로 설정합니다.

    LABEL "com.datadoghq.ad.check_names"='["coredns"]'
LABEL "com.datadoghq.ad.init_configs"='[{}]'
LABEL "com.datadoghq.ad.instances"='[{"openmetrics_endpoint":"http://%%host%%:9153/metrics", "tags":["dns-pod:%%host%%"]}]'

    이 OpenMetrics 기반 점검의 레거시 모드를 활성화하려면 openmetrics_endpoint를 prometheus_url로 교체하세요.

    LABEL "com.datadoghq.ad.instances"='[{"prometheus_url":"http://%%host%%:9153/metrics", "tags":["dns-pod:%%host%%"]}]'

    참고:

    • 전달된 coredns.d/auto_conf.yaml 파일은 기본적으로 레거시 모드에서 prometheus_url 옵션을 활성화합니다.
    • dns-pod 태그가 대상 DNS 파드 IP를 추적합니다. 다른 태그는 서비스 탐지를 사용해 정보를 폴링하는 Datadog 에이전트와 관련되어 있습니다.
    • 파드에서 서비스 탐지 주석을 해야 합니다. 배포하고 싶을 경우 템플릿 사양 메타데이터에 주석을 추가하세요. 외부 사양 수준에 추가하지 마세요.

    로그 수집

    기본적으로 로그 수집은 Datadog 에이전트에서 비활성화되어 있습니다. 활성화하려면 Docker 로그 수집을 참고하세요.

    그런 다음 Docker 레이블로 로그 통합을 설정하세요.

    LABEL "com.datadoghq.ad.logs"='[{"source":"coredns","service":"<SERVICE_NAME>"}]'
