aws grafana, prometheus 구성_6

Elasticache 모니터링

RDS 와 동일하다.

기존에 받았던 cloudwatch_exporter 의 examples/ElastiCache.yml 사용

cp -r a_account_ec2/ a_acount_cache

cd a_acount_cache

cp examples/ElastiCache.yml ./config.yml

 

cpu 와 free memory 만 모니터링

웹
모니터링서버 ip:9108

 

문제없이 열리면 완료.

 

이제 prometheus 수정

global:
  scrape_interval: 1m
  evaluation_interval: 1m

scrape_configs:
  - job_name: 'a_acount_ec2'
    static_configs:
      - targets: ['172.17.0.2:9106']
    metric_relabel_configs:
      - source_labels: [tag_Name]
        target_label: instance_name

  - job_name: 'a_acount_rds'
    static_configs:
      - targets: ['172.17.0.5:9106']

  - job_name: 'a_acount_cache'
    static_configs:
      - targets: ['172.17.0.6:9106']
      
      
      
1. 컨테이너에 직접 접속해서 수정
docker exec -it -u root prometheus /bin/sh

2. prometheus.yml 수정 후 이미지 - 새 컨테이너 구동
예시)
vi /home/ec2-user/prometheus/prometheus.yml
docker build -t prometheus:v2 .
docker run -d -p 9090:9090 --name prometheus prometheus:v2

1, 2 둘 중 하나 선택

저장 후
docker restart prometheus

 

prometheus 웹 새로고침 후

위와 같이 되면 완료.

 

grafana 로 이동

이전과 동일하게 dashboard 복붙 후 Edit

code

aws_elasticache_cpuutilization_average{cache_cluster_id=~".*(redis).*"}

Legend 는 {{cache_cluster_id}} 변경
