  • prometheus 로 관측할 대상에 대한 설치를 먼저 진행해보자

exporter 설치

모니터링 대상의 metric을 수집하고 prometheus가 접속했을 때 정보를 알려주는 역할

  • 종류
  • 해야할 설정
    • Exporter를 실행하면 데이터를 수집하는 동시에 HTTP 엔드 포인트를 열어서(node exporter의 기본은 9100포트) prometheus 서버가 데이터를 수집해 갈 수 있도록 한다. ( prometheus Server는 Exporter가 열어놓은 HTTP 엔드포인트에 접속해서 Metric을 수집하는 Pull 방식)

node exporter

https://github.com/prometheus/node_exporter

  • node exporter의 경우 호스트 시스템을 모니터링 하도록 설계되어 있기 떄문에, 호스트 시스템에 액세스 해야함.
    • Docker 컨테이너로 배포하는 것은 권장하는 바가 아니지만, docker 로 사용했을 때랑 그냥 서비스로 설치했을 때랑 플래그 조정만 한다면 개인적으론 차이를 느끼지 못했음
    • 배포의 편의성과 나중에 때어내거나 수정할 때 용의성을 위해 나는 docker-compose 로 작업했음.
  • Docker로 배포할 경우 주의 사항
    • 모니터링 하려는 루트가 아닌 마운트 지점은 컨테이너에 바인드 마운트해야함
  • node exporter 의 기본적으로 9100 포트에서 수신대기
  • node exporter 의 metrics 내용

docker 로 설치할 경우

# 그냥 docker 명령어로 실행할 경우
docker run -d \
  --net="host" \
  --pid="host" \
  -v "/:/host:ro,rslave" \
  quay.io/prometheus/node-exporter:latest \
  --path.rootfs=/host

docker-compose 로 설치할 경우

# docker-compose.yml 로 구성할 경우
version: '3.8'

services:
  node_exporter:
    image: quay.io/prometheus/node-exporter:latest
    container_name: node_exporter
    command:
      - '--path.rootfs=/host'
    network_mode: host
    pid: host
    restart: unless-stopped
    volumes:
      - '/:/host:ro,rslave'

테스트 하기

# node exporter 에 prometheus 가 와서 가져갈 metrics 확인하기
curl localhost:9100/metrics

데이터 검증하기

# cpu 관련
## node exporter 자료 - cpu 로드율
100 - (avg by(instance) (rate(node_cpu_seconds_total{mode="idle"}[2m])) * 100)
## top 의 자료 -> cmd 에 top 치고 세번쨰줄(cpu) 의 id % 부분 확인
## id 는 유휴 상태의 cpu 비중을 의미하기 때문에 100 -id 값이 위의 node exporter값과 같은지 확인

# hdd 사용량 관련
## node exporter 자료 - hdd 사용량(퍼센트)
(node_filesystem_avail_bytes * 100) / node_filesystem_size_bytes and ON (instance, device, mountpoint) node_filesystem_readonly == 0
## df -P 에서 루트 디렉토리의 사용량을 읽고 node-exporter의 자료와 같은지 확인
df -P

# memory 관련
## node-exporter의 자료 - 메모리 사용량(퍼센트)
node_memory_MemAvailable_bytes / node_memory_MemTotal_bytes * 100
## 방법1 ) top에서 memeory 사용량 보기
## 방법2 ) free 를 치고 memeory 사용량 보기

cadvisor

  • 도커 호스트에 컨테이너로서 실행되는 모니터링 툴로, 도커 엔진 및 컨테이너, 이미지 등에 대한 데이터등을 수집해준다.
  • 설치가 완료되면 아래와 같은 페이지를 열 수 있다.
    • prometheus 페이지처럼 간단하게 정보를 볼 수 있다.

docker로 설치하기

https://github.com/google/cadvisor

VERSION=v0.36.0 # use the latest release version from https://github.com/google/cadvisor/releases
sudo docker run \
  --volume=/:/rootfs:ro \
  --volume=/var/run:/var/run:ro \
  --volume=/sys:/sys:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \

  --detach=true \
  --name=cadvisor \
  --privileged \
  --device=/dev/kmsg \
  gcr.io/cadvisor/cadvisor:$VERSION

docker-compose 로 설치할 경우

  cadvisor:
    image: gcr.io/cadvisor/cadvisor:latest
    container_name: cadvisor 
    ports: 
      - 열기원하는포트:8080
