基于 Python 的 OpenStack 资源监控系统设计与实现 Design and Implementation of OpenStack Resource Monitoring System Based on Python摘 要为了优化 OpenStack 监控模块在功能和可视化方面的不足，确保OpenStack 实例的稳定运行，设计出一个用于 OpenStack 的监控系统。通过使用 Libvirt、Python 编程语言、Django 框架、Echarts 等开发技术，完成了拥有实时监控、实时报警功能的监控系统。该系统主要是通过每秒数据的输出绘制成图表来实现实时监控，还原当前运行资源的真实性。最后在本地虚拟环境下搭建 OpenStack 平台进行了测试，该系统能够 准 确 的 输 出 实 例 当 前 的 资 源 状 态 ， 实 现 报 警 等 功 能 。 解 决 了OpenStack 监控模块在功能和数据可视化方面的缺陷，并且对于OpenStack 监控模块从 Controller 节点获取资源数据而言，该系统直接从 Computer 节点获取资源数据，从而节省了 Controller 节点资源。关键词：OpenStack；资源监控；虚拟化；Libvirt；Python AbstractIn order to optimize the function and visualization of the OpenStack monitoring module and ensure the stable operation of the OpenStack instance, a monitoring system for OpenStack was designed. Through the use of Libvirt, Python programming language, Django framework, Echarts and other development technologies, a monitoring system with real-time monitoring and real-time alarm functions has been completed. The system mainly realizes real-time monitoring by drawing data output per second into a chart, restoring the authenticity of current running resources.Finally, the OpenStack platform was built and tested in a local virtual environment. The system can accurately output the current resource status of the instance and implement alarm and other functions. Solved the defects of the OpenStack monitoring module in terms of function and data visualization, and for the OpenStack monitoring module to obtain resource data from the Controller node, the system d...
