效能監控單元 (PMU) 是 CPU 核心內的硬體元件，可監控處理器執行程式碼的方式。在支援的執行個體中啟用 PMU 後，您可以使用效能監控軟體存取 PMU 中的效能計數器。這種做法可協助您找出並解決應用程式的效能瓶頸，進而最佳化效能敏感型工作負載，例如高效能運算 (HPC) 或機器學習 (ML)。
本文說明 PMU 的行為、計費方式和限制。如要瞭解如何在運算執行個體中啟用 PMU，請參閱「在 VM 中啟用 PMU」。
瞭解 PMU
PMU 由一組稱為效能監控計數器 (PMC) 的硬體計數器組成。這些計數器是特定於模型的暫存器，用於計算 CPU 內發生低階處理器事件的次數，例如分支預測錯誤或快取未命中。您可以使用 Intel VTune 分析器等效能監控軟體，在 PMU 中讀取及設定 PMC。
在 VM 中啟用 PMU 後，PMU 會在背景執行，並使用 PMC 持續監控效能事件。您也可以選擇使用偏好的效能監控軟體，為特定 PMC 設定門檻。如果 PMC 超過指定門檻，PMU 就會通知軟體。
PMU 事件
根據預設，VM 內會停用 PMU。如要啟用這項功能，請啟用下列其中一種 PMU 類型，指定要追蹤的低階 CPU 事件類型：
- 架構 (
ARCHITECTURAL)：您可以評估下列架構效能事件：
- 已淘汰的分支指令：已淘汰的分支指令數量。 您可以使用這項事件測量程式碼的執行情況，並找出潛在的效能瓶頸。
- Branch misses retired：預測錯誤的分支指令數量，導致處理器停止運作並捨棄擷取的指令。如果這個事件的數字很高，您可能可以最佳化 CPU 效能。
- 已完成的指令：CPU 成功處理的指令數量。使用這個事件評估 CPU 的指令輸送量。
- 由上而下的時段：處理器管道中可用的時段數量，用於同時執行指令。您可以透過這項事件，瞭解程式碼使用處理器資源的效率。
- 未暫停的核心週期：執行緒未暫停時的核心週期數，例如因電源管理或中斷而未暫停。您可以使用這項事件評估處理器的整體用量。
- 未暫停的參照週期：核心未暫停時的參照週期數，例如擷取資料或指令時。核心執行
HLT或MWAIT指令時會停止運作。參考週期以固定頻率運作，即使處理器速度改變以節省能源，仍可提供穩定的時間參考。您可以使用這項事件測量工作所花費的時間，並找出程式碼中的效能瓶頸。
- 標準 (
STANDARD)：您可以測量架構 PMU 類型中的所有事件，以及 CPU 核心內的任何本機事件，包括第 2 層 (L2) 快取事件。 - 增強型 (
ENHANCED)：您可以測量標準 PMU 類型中的所有事件，以及 CPU 核心以外的任何本機事件，包括第 3 級 (L3) 快取事件。
