zabbix自定义监控
自定义监控进程
测试监控httpd,需要在监控端部署httpd,以方便监控
``

配置监控脚本

#在监控端
[root@localhost ~]# dnf -y install httpd
[root@localhost ~]# systemctl start httpd
[root@localhost ~]# ss -anlt | grep 80
LISTEN 0      128                *:80               *:*   

#编写脚本
[root@localhost ~]# mkdir /scripts
[root@localhost ~]# vim /scripts/check_process.sh
#!/bin/bash

count=$(ps -ef|grep -Ev "grep|$0" | grep $1 | wc -l)
if [  $count -eq 0 ];then
        echo '1'
else
        echo '0'
fi
[root@localhost ~]# chmod +x /scripts/check_process.sh 
[root@localhost ~]# ll /scripts/check_process.sh
-rwxr-xr-x. 1 root root 119 Sep  6 21:09 /scripts/check_process.sh

#在监控端,修改配置文件
[root@localhost ~]# vim /usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UnsafeUserParameters=check_process[*],/bin/bash /scripts/check_process.sh $1

#服务端检查key是否可用
[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_process[httpd]
0
[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_process[mysql]
1
[root@zabbix ~]# zabbix_get -s 192.168.111.137 -k check_process[zabbix]

自定义监控日志
初学者复制的脚本
