适用场景

  • Cloud Volumes ONTAP
  • 无法在  指标下获取托管CVO节点的VM的CPU/内存利用率报告
  • CPU百分比始终显示99%

问题解答

  • 从云提供商 控制台查看的CPU利用率应为100%。
  • 在虚拟环境中, ONTAP 会使 vCPU 始终处于就绪状态,以提高系统性能。
  • ONTAP 不会在空闲时执行 halt CPU 指令,因此, vCPU 上的空闲线程似乎很热。
  • 从 AWS 角度来看,这将被视为 100% CPU 利用率。
  • 相比 之下,您可以从 ONTAP 的角度通过 ONTAP 命令行界面中的 sysstat (或 statistics show )命令查看实际 CPU 利用率。

追加信息

没有可用于CPU利用率的其他ONTAP级别警报功能。
