ONTAP 9及更高版本

问题描述

本文旨在指导您创建和安装自定义性能预设。
注意: 创建每个预设是为了收集 特定的数据集、以便进行故障排除。  应在NetApp技术支持的指导下执行此过程。

  • 统计信息 预设用于声明一个或多个性能对象名称的列表以及 计数器名称的列表(针对每个对象)。
  • 性能归档的预设配置会指定 每个计数器的采样周期
  • 预设使用 计数器管理器(CM) 框架中包含和组织的计数器。
  • CM以结构化分层 格式包含性能指标:object:instance:counter:value
    • 对象 -数据收集的基本单位/主题部分、例如volume
    • Instance —特定的数据单元、例如卷名称、vol10
    • 计数器 -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、无需指定为预设的一部分。
