6.6、拷贝证书¶
cd /data/nfs-volume/prometheus/etc/
cp /opt/certs/ca.pem ./
cp /opt/certs/client.pem ./
cp /opt/certs/client-key.pem ./
6.7、应用资源配置清单¶
kubectl apply -f http://k8s-yaml.zs.com/prometheus-server/rbac.yaml
kubectl apply -f http://k8s-yaml.zs.com/prometheus-server/dp.yaml
kubectl apply -f http://k8s-yaml.zs.com/prometheus-server/svc.yaml
kubectl apply -f http://k8s-yaml.zs.com/prometheus-server/ingress.yaml
6.8、访问验证¶
通过浏览器访问promethues.zs.com
6.9、纳入其他应用监控¶
6.9.1、Traefik纳入监控¶
修改traefik的yaml：
从dashboard里找到traefik的yaml，跟labels同级添加annotations
"annotations": {
"prometheus_io_scheme": "traefik",
"prometheus_io_path": "/metrics",
"prometheus_io_port": "8080"
}
等pod重启后，可以从Prometheus的web页面上看到
6.9.2、blackbox纳入¶
这个是检测容器内服务存活性的，也就是端口健康状态检查，分为tcp和http
我这里是启动的我们公司的一个eureka注册中心的服务
等服务起来以后，首先在对应的资源中添加一个TCP的annotation：
注意配置中的端口号，要对应自己的服务情况
"annotations": {
"blackbox_port": "9001",
"blackbox_scheme": "tcp"
}
可以通过Prometheus的web页面查看到下述页面
通过blackbox.zs.com页面可以看到新加入服务信息
也可以增加以下http资源，方法与tcp增加相同
"annotations": {
"blackbox_path": "/hello?name=health",
"blackbox_port": "8080",
"blackbox_scheme": "http"
}
Jvm监控
"annotations": {
"prometheus_io_scrape": "true",
"prometheus_io_port": "12346",
"prometheus_io_path": "/"
}
7、部署配置grafana¶
7.1、镜像准备¶
docker pull grafana/grafana:5.4.2
