zabbix4.0监控进程的CPU和内存利用率，内存占用

环境：zabbix4.0
系统：centos7.2

1 特定监控某些进程，需要写脚本监控

2 zabbix控制台添加模板

模板下载：https://down.51cto.com/data/2463398
将模板导入后可根据具体需求进行修改

cpu利用率

需要注明的是CPU占用率的值是带有小数点的一个数，所以在定义item的时候需要定义值得类型是浮点型，并且该值是占用逻辑单核的CPU占用率，所以需要定义自定义倍数，我实验中的服务器是4颗CPU（逻辑cpu），每颗CPU是4核8线程，所以自定义倍数是原来的基础上除以16（4x4），即乘以0.0625，单位改成%就好。
查看cpu逻辑cpu数

[root@confluence-jira ~]# cat /proc/cpuinfo |grep "processor"|wc -l
4

查cpu核数

[root@confluence-jira ~]# cat /proc/cpuinfo |grep "cores"|uniq
cpu cores   : 4

想对cpu，核了解更多请参考：https://www.hhcycj.com/post/item/261.html

内存利用率

图形展示如下：

内存占用

需要注明的是内存取到的值得单位是KB，所以定义item的时候使用自定义倍数乘以1000，单位改成Byte

3 zabbix获取cpu参数释义

zabbix默认模板自带有cpu jumps，cpu load，cpu utilization

CPU jum

context switches per second 进程线程切换
interrupts per second 每秒的中断次数
就是Process（Thread）的切换，如果切换过多，会让CPU忙于切换，也会导致影响吞吐量，值越高说明等待共享资源的线程数越多，每秒大量的上下文切换通常表明多个线程正在竞争共享资源

image.png

CPU load

某一段时间内，CPU正在处理以及等待CPU处理的进程数的之和，load高说明CPU利用率低

image.png

CPU Utilization

是CPU的利用率（某一时间段内cpu资源占用情况），通常界定80%。
