适用场景

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

问题描述

性能顾问是OnCommand统一管理器(DFM)的一部分、从本质上说、它定期连接到Data ONTAP中的计数器管理器、将这些示例存储在OnCommand统一管理器服务器上、并可针对多个控制器进行配置。这样、管理员就可以拥有一个图形前端来存储性能数据、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。它通常在需要特定控制器性能的详细视图时临时运行。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、在事件发生时就可以捕获详细信息、而不是依赖手动perfstat。一个很好的例子是、定义特定性能特征、然后在下次检测到该特征时自动启动perfstat的过程。
