效能計數器

《The》介紹各個系統效能的豐富資訊ONTAP ONTAP 。它會將此資料匯出為一組_效能計數器_、您可以用來評估ONTAP 您的整套系統效能、並協助達成您的效能目標。

存取ONTAP 效能計數器

您可以ONTAP 使用兩個不同的API、以及ONTAP 透過VMware命令列介面來存取VMware效能計數器。

註 在自動化管理您的VMware部署時、支援使用支援功能的API是首選且具策略性的選項ONTAP ONTAP 。

ONTAPI API

NetApp Network Manageability SDK提供ONTAPI API。使用ONTAPI時、效能計數器會在物件集合內定義。每個物件對應於系統的實體或虛擬元件。根據系統組態、每個物件可以有一個或多個執行個體。

例如ONTAP 、如果您的支援系統有四個實體磁碟、則會有四個執行個體 disk 物件、每個物件都有自己的一組效能計數器。您可以使用ONTAPI來存取每個磁碟執行個體的個別計數器。

靜態API ONTAP

從VMware版本9.11.1開始ONTAP 、您也可以透過REST API存取效能資料。在這種情況下、效能計數器會組織成相當於ONTAPI物件的表格。每個表格列都相當於ONTAPI物件的執行個體。

例如ONTAP 、如果您的支援系統有四個實體磁碟 disk 表格將包含四列。每一列都可以個別存取、並包含一組效能計數器、可在該列中作為欄位或欄位使用。

準備使用REST API

您應該先準備好、再使用ONTAP REST API存取效能計數器。

效能計數器會組織在表格中

ONTAPI物件的子集可透過ONTAP REST API取得、並顯示為表格。例如、ONTAPI *主機介面卡*物件透過REST API呈現為*主機_adpater*表格。系統中的每個主機介面卡都是一列、有自己的一組效能計數器。

其餘端點的摘要

共有四個主要端點可供存取ONTAP 不景效能計數器和相關表格。

註 每個REST端點都提供唯讀存取、而且僅支援* Get* HTTP方法。請參閱 "API 參考" 以取得更多資訊。

  • /叢集/計數器/表格

    傳回計數器表格及其架構定義的集合。

  • /叢集/計數器/表格/｛name｝

    傳回單一命名計數器表格的相關資訊。

  • /叢集/計數器/表格/｛counter_name｝/資料列

    傳回命名計數器表格中的列集合。

  • /叢集/計數器/表格/｛counter_name｝/列/｛id｝

    從命名的計數器表格傳回特定列。

從ONTAPI移轉至REST API

NetApp提供廣泛的支援、可將自動化程式碼從ONTAPI移轉至ONTAP REST API。這包括對應文件、以識別特定ONTAPI物件REST API中可用的等效效能計數器表。

請參閱您ONTAP 所使用之版本資訊的適當對應文件：

開始使用ONTAP 靜態API

以下範例說明如何使用REST API來存取ONTAP VMware效能計數器。這包括擷取可用表格的清單、以及探索表格結構。

開始之前

請先檢閱下列資訊、再使用範例。

身分證明ONTAP

您需要ONTAP 一個包含密碼在內的管理員帳戶。

叢集管理IP

您將需要為ONTAP 您的支援系統設定叢集管理IP位址。

所有API呼叫都使用Get方法

下列所有範例僅可用於擷取HTTP Get方法的資訊。

變動替代

每個Curl範例都包含一個或多個以大寫和方括弧括住文字表示的變數。請務必將這些變數替換成適合您環境的實際值。

範例符合端點

下列範例順序說明如何使用可用於擷取效能計數器的REST端點。請參閱 其餘端點的摘要 以取得更多資訊。

範例1：所有效能計數器表

您可以使用此REST API呼叫來探索所有可用的計數器管理器表格。
