istio收集Metrics和日志信息
1.切换到istio根目录
cd /data/istio/istio-0.7.1
2.安装prometheus
kubectl apply -f install/kubernetes/addons/prometheus.yaml
3.创建收集数据的模板

执行命令:
istioctl create -f new_telemetry.yaml
istioctl create -f tcp_telemetry.yaml
为了测试支持收集tcp metric数据:
kubectl apply -f <(istioctl kube-inject -f samples/bookinfo/kube/bookinfo-ratings-v2.yaml)
kubectl apply -f <(istioctl kube-inject -f samples/bookinfo/kube/bookinfo-db.yaml)
istioctl create -f samples/bookinfo/kube/route-rule-ratings-db.yaml
4.测试
1)访问bookinfo事例
http://192.168.181.99:32693/productpage
2)查看prometheus ui
