自定义脚本监控
1.进程监控
修改配置文件/usr/local/etc/zabbix_agentd.conf
UnsafeUserParameters=1
UserParameter=check_process[*],/bin/bash /scripts/check_process.sh $1
配置进程监控的脚本
#!/bin/bash
process_status=$(ps -ef|grep $1|grep -Ev "grep|$0"|wc -l)
if [ $process_status -eq 0 ];then
echo '1'
else
echo '0'
fi
添加监控项
关掉postfix服务
[root@longnian etc]# systemctl stop postfix
再次查看
添加触发器
触发结果
2.日志监控
添加内容到配置文件/usr/local/etc/zabbix_agentd.conf
UserParameter=check_logs[*],/usr/bin/python /scripts/log.py $1 $2 $3
添加监控项
添加触发器

3.mysql主从状态监控
客户端安装mariadb（做服务端）
[root@longnian ~]# mysql
