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在空闲时不执行暂停CPU指令、这会使空闲线程在vCPU上看起来很热。
  • 从AWS角度来看、这将视为100%的CPU利用率。
  • 相比之下、您可以 在ONTAP命令行界面中使用sysstat (或statics show)命令从ONTAP的角度查看实际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。
