标题 No.6 - 虚拟化场景下的性能调测工具 virttop

描述 云场景,性能类问题无法快速定位定界,缺少定位手段。例如CPU性能不足,网络性能抖动等常见问题定位周期长,定位手段少。CPU超分场景经常出现虚拟机的 vcpu争抢,需要提供vcpu使用监控手段,期望能够提供一套类似top的实时监测工具。

产出标准

  1. 实时查询kvm虚拟机性能信息的用户层软件,方便性能问题定位
  2. 查询虚拟机的cpu占用率、调度时延、虚拟化开销、陷入陷出次数等vcpu信息以及内存占用、
  3. 内存带宽使用、LLC使用情况等其他性能相关信息
  4. 使用方式类似top命令
  5. 代码仓库 https://gitee.com/src-openeuler/virttop

技术要求

  1. 代码符合开源要求
  2. 参考top源码或者基于top提供的能力
  3. C语言或C++
