Zabbix 监控 CPU 使用率

1、创建监控项

2、　创建监控图形

3、创建触发器

zabbix （3.4.2）添加监控项，触发器，让CPU使用超过85%就报警

4、配置—>模板—->找到Template OS Linux模板—监控项

CPU 剩余百分比
5、创建监控项—-> 改名称—–>选择进入

6、添加触发器，想要报警，就要有一个临界值，超过这个临界值的时候就报警。这个临界值发起里面设置的。
配置—>模板—->找到Template OS Linux模板 —创建触发器

7、添加图形：配置—>模板—->图形—->

8、添加成功之后会看到图形，如果其他地方操作没有错误，等几分钟就会有图形：
这就实现了监控CPU使用量超过85%就报警。剩余量低于15%，也就是使用量高于85%
3，在监控的本机给他来个压测，）

注意：先用一个小一点的数字测试，观察图形之后再逐步加大（建议先用500测试一下），

[root@zabbix_server ~]#echo "scale=5000; 4*a(1)" | bc -l -q

这条命令是计算圆周率后面的5000位

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


图形展示如下：

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


图形展示如下：

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

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

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%。

参考：https://www.cnblogs.com/lidabo/p/9360342.html

扩展

监控cpu

定义规则：创建模板—>群组—>应用集—>监控项—>图形—>触发器—>添加主机（加入到群组，关联模板）

1）cpu空闲率，用户态使用率，内核态使用率
键值：system.cpu.util[,idle]

• 键值：system.cpu.util[,user]
