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] 0

自定义监控日志

初学者复制的脚本
忘情的log脚本日志
