系统 centos7

被监控端

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

yum install zabbix-agent

修改配置文件

vim /etc/zabbix/zabbix_agentd.conf

117 Server=192.168.0.199  # 监控端IP

启动客户端

systemctl start  zabbix-agent
systemctl status  zabbix-agent

监控端

创建主机

添加监控项

键值：vfs.fs.size[/data,pfree]

创建触发器

表达式: {200:vfs.fs.size[/data,pfree].last()}=20

配置zabbix发送告警到钉钉

先去钉钉上获取[webhook地址 和 app_secret]

打开一个想要将预警消息推送到的钉钉群
 群设置->智能群助手->添加机器人->选择自定义机器人

编写DingDingWarn.py

#!/bin/python3
# -*- coding:utf-8 -*-
import base64
import hashlib
import hmac

"""

将脚本文件放到 /usr/lib/zabbix/alertscripts/ 下
