搭建Prometheus Grafana Go监控平台

一、前言

监控指标

Go监控指标有好多库,监控指标大致一样。
1)https://github.com/bmhatfield/go-runtime-metrics
2)https://github.com/tevjef/go-runtime-metrics
3)Prometheus SDK

指标输出

1)golang expvar
2)Prometheus

二、Prometheus搭建

镜像设置

docker pull mirrorgooglecontainers/addon-resizer:1.8.3
docker tag mirrorgooglecontainers/addon-resizer:1.8.3 k8s.gcr.io/addon-resizer:1.8.3
docker pull mirrorgooglecontainers/heapster-grafana-amd64:v5.0.4
docker tag mirrorgooglecontainers/heapster-grafana-amd64:v5.0.4 k8s.gcr.io/heapster-grafana-amd64:v5.0.4

prometheus部署

kubectl apply -f alertmanager
kubectl apply -f prometheus
kubectl apply -f kube-state-metrics
kubectl apply -f node-exporter
kubectl apply -f grafana

检查

kubectl get pod -n monitoring
kubectl get svc -n monitoring

三、Grafana搭建

数据源配置

Dashboard配置

https://grafana.com/grafana/dashboards/6671

四、效果展示

自定义job

查看指标

dashboard展示pod信息

实现

prometheus参考Thakurvaibhav的作品,并进行改造。
demo项目使用prometheus-client
