개요

k6는 성능 문제와 퇴보를 조기에 발견하는 데 도움이 되는 오픈 소스 부하 테스트 도구입니다.

k6 통합을 사용하면 k6 테스트의 성능 메트릭을 추적할 수 있습니다.

  • 애플리케이션 성능과 부하 테스트의 상관관계를 파악합니다.
  • 성능 테스팅 메트릭 기반 알림을 생성합니다.
  • k6 Datadog 대시보드 또는 메트릭 탐색기를 사용하여 k6 메트릭을 분석하고 시각화합니다.

설정

자세한 지침은 k6 설명서를 참조하세요.

설치

  1. Datadog에서 통합 > API로 이동하여 API 키를 복사합니다.

  2. Datadog 에이전트를 실행합니다.

    k6 메트릭을 Datadog로 가져오려면 k6은 Datadog 에이전트를 통해 메트릭을 전송합니다. Datadog 에이전트는 Datadog 플랫폼으로 메트릭을 수집, 집계하고 전달합니다.

    다음 명령으로 Datadog 에이전트 서비스를 도커(Docker) 컨테이너로 실행합니다.

    DOCKER_CONTENT_TRUST=1 \
docker run -d \
    --name datadog \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \
    -v /proc/:/host/proc/:ro \
    -v /sys/fs/cgroup/:/host/sys/fs/cgroup:ro \
    -e DD_SITE="datadoghq.com" \
    -e DD_API_KEY=<YOUR_DATADOG_API_KEY> \
    -e DD_DOGSTATSD_NON_LOCAL_TRAFFIC=1 \
    -p 8125:8125/udp \
    datadog/agent:latest

    참고: <YOUR_DATADOG_API_KEY>를 API 키로 바꿉니다. 계정이 Datadog EU에 등록된 경우 DD_SITE의 값을 datadoghq.eu로 변경합니다.

  3. k6 테스트를 실행하고 결과를 Datadog로 출력합니다.

    Datadog 에이전트 서비스가 실행되면 k6 테스트를 실행하고 메트릭을 에이전트로 전송하세요.

    K6_STATSD_ENABLE_TAGS=true k6 run --out statsd script.js

  4. Datadog에서 k6 메트릭을 시각화합니다.

    테스트를 실행하는 동안 k6는 Datadog로 메트릭을 주기적으로 전송합니다. 기본적으로 메트릭에는 k6.이 이름 접두사로 사용됩니다.

    메트릭 탐색기, 모니터 또는 커스텀 대시보드 를 통해 k6 메트릭을 실시간으로 시각화할 수 있습니다.

    또한 Datadog 이 k6.http_reqs 메트릭을 처음 감지하면 k6 통합 타일이 자동으로 설치되고 기본 k6 대시보드 이 [대시보드 목록 ]에 추가됩니다9.
