CA APM Kubernetes Monitor

CA APM Kubernetes Monitoring是一个扩展，提供对通过Kubernetes部署、扩展和管理的容器化应用的全面监控洞察。使用该扩展可监控容器化应用、进程和云实例的可用性与性能，实时管理Docker和Kubernetes容器集群中主机与应用的依赖关系，并利用收集的指标数据优化环境的伸缩。

安装

运行以下yml文件：

kubectl create -f caagent-kubernetesmonitor.yml 

注意：

• 以下YML文件包含部署和守护进程集，容器需要以特权模式运行。

• 替换以下变量为您的设置详情：

[AGENTMANAGER_URL] ：Agent/EM连接详情 - 与IntroscopeAgent.profile中提供的类似
[AGENTMANAGER_CREDENTIAL]：连接任何SaaS实例所需的Agent Manager凭据 
[KUBERNETES_CONNECTION_URL]：Kubernetes连接详情。可通过运行kubectl config view获取
[APITOKEN]：连接URL的API令牌。您可以通过在默认工作区创建具有cluster-reader角色的服务账户来获取。

如何获取APITOKEN

• 在"default"命名空间创建服务账户：

kubectl create sa caapm

• 添加cluster-reader角色：

kubectl create clusterrolebinding cluster-read --serviceaccount=default:caapm  --clusterrole=cluster-admin

• 获取令牌：

kubectl get secrets|grep caapm-token| cut -f1 -d " "|xargs kubectl describe secret | grep token

卸载

kubectl delete -f caagent-kubernetesmonitor.yml
