zabbix监控进程的CPU和内存占用量

        需要对特定服务进行监控，于是，通过编写脚本获取各个进程占用系统资源的信息，从而使用zabbix采集到这些数据进行特定进程的基础监控。

        主要需要监控的程序如下：

        nginx、 redis、 mysql、 tomcat、 sentinel、 mongodb、 openfire、 kafka、 zookeeper、 twemproxy、 mycat

        首先，在agent端编写监控脚本，脚本内容如下：

        然后修改脚本的权限，使用：

1
chmod +x processstatus.sh

        在zabbix_agentd.con配置文件中末尾增加如下代码：

        最后重启zabbix_agentd服务

1
2
pkill zabbix
zabbix-2.4.4/sbin/zabbix_agentd

        然后在zabbix服务端使用zabbix_get看能否取到相应的数据，像下面这样就是成功获取到了数据。

1
2
[root@localhost zabbix-2.4.4]# bin/zabbix_get -s 172.16.1.20 -p 10050 -k process.nginx.memory
184876

        最后，需要在zabbix中定义模板。模板附件链接在下面。

        zabbix模板下载

        如果模板无法下载可以在附件中下载模板

        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，另外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2颗CPU，每颗CPU是8核16线程，所以自定义倍数是原来 的基础上除以32，单位改成%就好。

        下面是做好之后的显示效果：
