簡介
本文檔介紹用於監控Cisco Nexus 7000系列平台上的CPU使用率和解決CPU使用率過高問題的進程。
Nexus 7000平台上的CPU使用情況
Nexus 7000平台是一個基於Linux的系統，具有搶佔式排程程式，允許對所有進程的CPU資源進行公平訪問。
與Cisco Catalyst 6500系列不同的是，沒有單獨的路由處理器(RP)和交換機處理器(SP)。
- Supervisor Engine 1配備雙核心處理器。
- Supervisor Engine 2配備四核心處理器。
- Supervisor Engine 2E有兩個四核心處理器。
Cisco NX-OS作業系統利用搶佔式CPU多工處理，因此進程可以利用空閒的CPU更快地完成任務。
因此，「歷史記錄」選項會報告未必表示問題的可能的CPU峰值。但是，如果平均CPU使用率與特定網路的基準CPU使用率正常相比仍然很高，請調查高CPU使用率。
啟用預設硬體速率限制器(HWRL)和預設控制平面策略(CoPP)，以幫助保護Nexus 7000平台上的管理引擎帶內介面。
命令和示例EEM指令碼基於Nexus 7000版本6.1及更早版本，未來版本可能會更改。
用於監視進程和CPU的命令和指令碼
命令
Cisco CLI Analyzer（僅供已註冊客戶使用）支援某些 show 指令。使用 Cisco CLI Analyzer 檢視 show 指令輸出的分析。
show processes命令
使用此命令可顯示有關活動進程的資訊。

EEM指令碼示例
這是一個捕獲間歇性高CPU使用率的示例指令碼。使用的值以及發出的命令可以根據要求進行修改：
event manager applet HIGH-CPU
event snmp oid 1.3.6.1.4.1.9.9.109.1.1.1.1.6.1 get-type exact entry-op ge
entry-val 80 exit-val 30 poll-interval 5
action 1.0 syslog msg High CPU hit $_event_pub_time
action 2.0 cli enable
action 3.0 cli show clock >> bootflash:high-cpu.txt
action 4.0 cli show processes cpu sort >> bootflash:high-cpu.txt
注意：必須定義「exit-val」。 當指令碼收集資料時，會增加CPU利用率。exit-val的值可確保指令碼不會在無限循環中運行。
進程或流量造成的CPU使用率較高
當CPU使用率受到監控時，沒有進程與中斷CPU使用率(如在Cisco IOS®軟體平台上)。確定CPU使用率較高原因的一種快速方法是使用show system internal processes cpu命令。通常，流量觸發的CPU使用率高會導致Netstack以及其他功能和進程(如地址解析協定(ARP)和網際網路組管理協定(IGMP))運行率高。
進程導致高CPU使用率
根據導致高CPU使用率的進程和問題，可能需要捕獲特定命令。以下各節介紹有用的方法。
show system internal <feature> mem-stats/memstats | 在大型命令中
使用此命令可顯示進程的記憶體分配；使用「in Grand」選項可監視總記憶體。記憶體洩漏可能導致進程行為不當，從而導致CPU使用率較高。
Ethanalyzer
使用Ethanalyzer監控到CPU的流量。
debug命令
附註：使用 debug 指令之前，請先參閱有關 Debug 指令的重要資訊。在生產交換機上明智地使用debug命令，以避免服務中斷。
儘可能使用debug logfile命令將輸出定向到指定檔案，並避免鎖定會話以填滿syslog。以下是偵錯簡易網路管理通訊協定(SNMP)的範例：
switch# debug logfile snmpdebug
switch# debug snmp all
switch# show debug logfile snmpdebug

流量導致高CPU使用率
當流量導致高CPU使用率時，使用以下工具：
- Ethanalyzer -監控與CPU之間的流量型別。
- Configuration -檢查交換機/介面/功能配置
- CoPP/硬體速率限制器 -確保CoPP和HWRL配置正確。有時CPU運行率不高，因為它受到CoPP和速率限制器的保護。檢查CoPP和HWRL，檢視是否有特定流量/資料包的丟棄。
註：CoPP和HWRL都僅在預設虛擬裝置環境(VDC)中可用。它們由每個單獨的I/O模組執行。來自多個模組的聚合流量仍然會對CPU造成沈重負擔。
高CPU使用率的根本原因分析
網路中斷可以透過使用者干預來解決，也可以自行恢復。如果您懷疑CPU使用率過高導致了網路中斷，請使用以下準則來調查原因。
症狀
CPU使用率高的症狀包括控制平面不穩定、控制平面故障導致的資料平面連線問題、熱備用路由器協定(HSRP)/RP抖動等協定抖動、UDLD錯誤停用、生成樹協定(STP)故障以及其他連線問題。
CPU歷史記錄
show processes cpu history命令
如果交換機未重新載入或未進行切換，請在服務中斷的72小時內運行show processes cpu history命令，以檢視事件發生時是否出現CPU使用率較高的情況。
CoPP和HWRL
如果CPU使用率高是過去中斷的根本原因，並且您懷疑中斷是由網路流量觸發的，您可以使用CoPP和HWRL（硬體速率限制器）來幫助辨識流量的型別。
