容器微云监控系统的设计和实现

微云是一种网络边缘的小型数据中心，能够以较低的延迟为用户的资源密集型应用提供服务.相较于主流的虚拟机技术，容器技术以资源利用率高，接近物理机的性能，启动迅速等特点，成为构建微云的首选.微云的运行离不开监控，本文结合现有集群监控系统的成熟架构，并结合容器微云的特点，设计并实现了一套基于容器技术的微云的监控系统，实现了监控数据的收集，存储，汇总，展示，异常检测及阈值和收集周期动态设置，同时，为了降低带宽的占用，提出了请求聚合算法.通过实际的部署和测试，证明该系统能够以较低的负载满足各项设计需求.
Abstract：Cloudlet, which can perform resource-intensive applications for users with low delay, is a small data center located at the edge of the Internet. Compared to virtual machine technology, container technology has become the first choice to build a cloudlet due to its higher resource use rate, physical-machine-like performance and faster boot speed. The monitoring system is indispensable to the operation of a cloudlet. Combining the maturity framework of existing monitoring systems and the characteristics of container-based cloudlet, a monitoring system was designed and implemented for container-based cloudlets. And the monitoring system realizes the collection, storage, aggregating and displaying of monitoring data, anomaly detection, and dynamic settings of thresholds and collection cycles. At the same time, a request aggregating algorithm was proposed to reduce. Actual deployment and testing indicate that the system can meet the design requirements with low load.
