Datadog is a monitoring service that gathers monitoring data from your containers within your Azure Container Service cluster. Datadog has a Docker Integration Dashboard where you can see specific metrics within your containers. Metrics gathered from your containers are organized by CPU, Memory, Network and I/O. Datadog splits metrics into containers and images.

一、你需要准备的东西：

1. 你需要有一个k8s集群，创建k8s集群的过程此处省略，方法多种，我目前使用的是Azure Container Service Engine.
2. 需要创建一个Datadog账号 create an account

登陆到Datadog以后，按照此文档去安装Datadog agent。注意其中的datadog-agent.yaml 这个文件，把它copy出备用

二、安装过程：

kubectl create -f datadog-agent.yaml


安装Helm

sudo snap install helm

helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.9.1 --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts


helm search


https://app.datadoghq.com/account/settings#api

helm install --name wbdatadog --set datadog.apiKey=5606443cd7359ac1ba6815**** stable/datadog


helm list


三、我们的基本结果：

成功后，登陆Datadog，能看到我们的k8s node list：
