pmm server

install

helm repo add percona https://percona-charts.storage.googleapis.com
helm repo update
NS=pxc-mysql
helm install monitoring pmm/pmm-server -n $NS --set platform=kubernetes --set "credentials.password=your_password"

ingress 설정

cert-manager가 설정이 미리 되있어서 ssl까지 만들면서 진행

백앤드에 ssl로 통신하는것 중요

사이트에 접속해보면 grafana가 보인다. 로그인하면 된다.

pmm-client

cr.yaml

pmm:
  enabled: true
  image: percona/pmm-client:2.18.0
  serverHost: pxc-pmm-service # pmm-server에서의 서비스 명
  serverUser: admin # 확인

k apply -f cr.yaml

자동으로 서버를 찾아서 자기 스스로를 등록한다.

pmm 확인

pmm.c3.yourdomain.com 으로 들어가서 확인해보면 많은 데이터를 볼수 있다.

다 구성되고 나면 pmm 에 접속해보면 클러스터 상태가 보인다.

alert manager를 설정하면 슬랙으로 에러를 받을수 있다.

subchart 로 argocd에서 설정

argocd 에서 subchart를 사용 해야 gitops가 된다.

subchart로 만들자.

mkdir pmm
cd pmm

ingress까지 잘 적용되는것을 알수있다.

k apply -f add-pmm-server.yaml

잘 적용된다.
