2 zabbix控制臺(tái)添加模板
模板下載：https://down.51cto.com/data/2463398
將模板導(dǎo)入后可根據(jù)具體需求進(jìn)行修改
cpu利用率
需要注明的是CPU占用率的值是帶有小數(shù)點(diǎn)的一個(gè)數(shù)，所以在定義item的時(shí)候需要定義值得類型是浮點(diǎn)型，并且該值是占用邏輯單核的CPU占用率，所以需要定義自定義倍數(shù)，我實(shí)驗(yàn)中的服務(wù)器是4顆CPU（邏輯cpu），每顆CPU是4核8線程，所以自定義倍數(shù)是原來的基礎(chǔ)上除以16（4x4），即乘以0.0625，單位改成%就好。
查看cpu邏輯cpu數(shù)
[root@confluence-jira ~]# cat /proc/cpuinfo |grep "processor"|wc -l
4
查cpu核數(shù)
[root@confluence-jira ~]# cat /proc/cpuinfo |grep "cores"|uniq
cpu cores : 4

內(nèi)存占用
需要注明的是內(nèi)存取到的值得單位是KB，所以定義item的時(shí)候使用自定義倍數(shù)乘以1000，單位改成Byte

3 zabbix獲取cpu參數(shù)釋義
zabbix默認(rèn)模板自帶有cpu jumps，cpu load，cpu utilization
CPU jum
context switches per second 進(jìn)程線程切換
interrupts per second 每秒的中斷次數(shù)
就是Process（Thread）的切換，如果切換過多，會(huì)讓CPU忙于切換，也會(huì)導(dǎo)致影響吞吐量，值越高說明等待共享資源的線程數(shù)越多，每秒大量的上下文切換通常表明多個(gè)線程正在競爭共享資源
image.png
CPU load
某一段時(shí)間內(nèi)，CPU正在處理以及等待CPU處理的進(jìn)程數(shù)的之和，load高說明CPU利用率低
image.png
CPU Utilization
是CPU的利用率（某一時(shí)間段內(nèi)cpu資源占用情況），通常界定80%。
