目標：
維持 vCenter Server Appliance 可接受的效能和資源使用程度。
事實：
vCenter Server Appliance
服務
效能
vCenter Server Appliance 管理介面 （VAMI）
程序：
CPU 效能
vCSA 不應超過 70% 的恆定 CPU 使用量。
如果 VPXD 進程消耗了大部分 CPU，並且超過 70%，請考慮以下建議：
- 新增更多 CPU 至 vCSA。
- 新增更多 vCSA 例項，以平衡所有 vCSA 例項之間的負載。
如果 Java 服務消耗了大部分 CPU，則應增加該服務的堆記憶體大小。
記憶體效能
vCSA 不應超過 70% 的持續記憶體使用量。
如果記憶體使用率持續超過 70%，請執行下列步驟：
- 驗證 vCSA 是否正在交換。請參閱 VMware 文章中的資訊：記憶體效能問題的解決方案
- 驗證哪些服務的CPU使用率很高。
- 高 CPU 使用率可能表示交換過多，因為處理交換作業需要 CPU。
- 如果高使用率一致，則可能需要添加記憶體。
- 如果叢集中的記憶體過度使用，請考慮設定 vCSA 的保留。
使用 VAMI 監控 CPU 和記憶體使用方式
- 存取 vCSA 的 VAMI。
https://vCSA_IP Or FQDN:5480
- 前往左側 的顯示器 ，然後選取 CPU 和記憶體。

- 或者，
<vimtop>命令可用來監視 vCSA 資源。- 使用 PuTTY 工作階段登入 vCSA Shell。
- 發出命令，並檢閱 CPU 和記憶體的指標。

檢視服務記憶體配置
這 <cloudvm-ram-size> 命令顯示分配給 vCenter Server 服務的記憶體量。在以下範例中，可以看到 vSphere UI 服務使用分配給 vCSA 的 12,000 MB 中的 853 MB。

檢視服務堆大小
vCenter Server 包含數種 Java 服務。Java 服務使用堆（預先保留的記憶體）來存儲數據物件。適當的堆大小對於以最佳方式執行非常重要。在下列情況下，vSphere UI 可能需要更大的堆積大小：
- 強化連結模式的多個 vCenter Server 執行個體
- 許多延伸和外掛程式
- 大量庫存
可使用 <cloudvm-ram-size -J service_name> 命令顯示用於堆的總記憶體。在下面的示例中，可以看到 vSphere UI 服務的堆使用的是分配的 853 MB 中的 597 MB。

如果由於效能問題而必須變更服務堆大小，請參閱 VMware 文章：手動增加 vCenter Server 元件上的堆積記憶體
