  • Data ONTAP 7 及更早版本
  • OnCommand Unified Manager 5.x

问题描述

Performance Advisor是OnCommand Unified Manager (DFM)的组成部分、它基本上会定期连接到Data ONTAP 中的计数器管理器、并将这些样本存储在OnCommand Unified Manager服务器上、并且可以为多个控制器进行配置。这样、管理员就可以使用图形前端查看性能数据、同时还可以保留、报告和提醒历史记录。

配置Performance Advisor后、它会在后台持续运行;而perfstat则会提供有关Data ONTAP 性能方面的非常详细的信息。当需要详细了解特定控制器的性能时、它通常会临时运行。perfstat可提供更详细的信息;但是、它不会持续收集每个控制器上的数据。

Performance Advisor的重要功能是轮询、查找特定场景、然后触发perfstat收集。这样可以在事件发生时捕获详细信息、而不是依赖手动perfstat。一个很好的示例是定义特定性能特征、然后在下次检测到perfstat特性时自动启动的过程。
