问题描述

本文旨在指导您完成自定义性能预设的创建和安装。
注意:每个预设都是为收集特定数据集来进行故障排除而创建的。应按照 NetApp 技术支持的指示执行此过程。

  • 统计信息预设可声明一个或多个性能对象名称的列表以及一个计数器名称列表(针对每个对象)。
  • 性能归档的预设配置会为每个计数器指定采样周期
  • 预设使用计数器管理器( CM )框架中包含和组织的计数器。
  • CM 包含结构化分层格式的性能指标: object:instance:counter:value
    • 对象—数据收集的基本单元 / 主题部分,例如 volume
    • 实例—特定的数据单元,例如卷名称, vol10
    • counter —从该对象中收集的数据点,例如 avg_latency
    • value —收集的数据,例如 1120us
    • CM 性能指标的示例如下:  volume:vol10:avg_latency:1120us
  • 指定自定义预设时,只需要定义对象和计数器。 
    • 实例和值数据会自动收集,不需要在预设中指定。
