第四篇Zabbix增加微信告警[必备]

Posted 2021-03-20 小粉优化大师

这里采用的是Python程序发送企业微信，所以需要安装Python环境

1、下载Python 3版本以上的版本

下载地址：https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz

2、开始安装Python环境

#安装依赖库
[root@filestore-v2 ~]# yum install gcc gcc-c++ glibc-devel glibc zlib-devel zlib openssl-devel openssl sqlite-devel readline-devel -y

#解压进入安装目录
[root@filestore-v2 Python-3.6.6]# tar xvf Python-3.6.6.tgz && cd Python-3.6.6

#编译安装软件
[root@filestore-v2 Python-3.6.6]# ./configure --prefix=/usr/local/Python-3.6.6 --enable-shared --with-ssl && make && make install

#查看安装的目录
[root@filestore-v2 Python-3.6.6]# tree -L 1 /usr/local/Python-3.6.6/
/usr/local/Python-3.6.6/
├── bin
├── include
├── lib
└── share

#配置动态连接库
[root@filestore-v2 Python-3.6.6]# vi /etc/ld.so.conf.d/Python-3.6.6.conf 
/usr/local/Python-3.6.6/lib

#刷新动态连接库
[root@filestore-v2 ~]# ldconfig

#这里不增加环境变量，只做软链接（看个人喜好决定）
[root@filestore-v2 ~]# ln -s /usr/local/Python-3.6.6/bin/python3 /sbin/python3
[root@filestore-v2 ~]# ln -s /usr/local/Python-3.6.6/bin/pip3 /sbin/pip3

#测试是否安装成功
[root@filestore-v2 ~]# python3  #这样子表示成功
Python 3.6.6 (default, Dec 25 2019, 15:40:39) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux

 3、安装requests模块

[root@filestore-v2 ~]# pip3 install requests

4、创建发送脚本程序

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import requests
import json
import sys

# 企业号及应用相关信息
corp_id = \'企业ID\'
corp_secret = \'应用的密钥\'
agent_id = \'应用的ID\'
# 存放access_token文件路径
file_path = \'/tmp/access_token.log\'


def get_access_token_from_file():
    try:
        f = open(file_path, \'r+\')
        this_access_token = f.read()
        print(\'get success %s\' % this_access_token)
        f.close()
        return this_access_token
    except Exception as e:
        print(e)


# 获取token函数，文本里记录的token失效时调用
def get_access_token():
    get_token_url = \'https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=%s&corpsecret=%s\' % (corp_id, corp_secret)
    print(get_token_url)
    r = requests.get(get_token_url)
    request_json = r.json()
    this_access_token = request_json[\'access_token\']
    print(this_access_token)
    r.close()
    # 把获取到的access_token写入文本
    try:
        f = open(file_path, \'w+\')
        f.write(this_access_token)
        f.close()
    except Exception as e:
        print(e)

    # 返回获取到的access_token值
    return this_access_token


# snedMessage
# 死循环，直到消息成功发送
flag = True
while (flag):
    # 从文本获取access_token
    access_token = get_access_token_from_file()
    try:
        to_user = \'@all\'
        message = sys.argv[3]
        send_message_url = \'https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=%s\' % access_token
        # print(send_message_url)
        message_params = {
            "touser": to_user,
            "msgtype": "text",
            "agentid": agent_id,
            "text": {
                "content": message
            },
            "safe": 0
        }
        r = requests.post(send_message_url, data=json.dumps(message_params))
        print(\'post success %s \' % r.text)
        # 判断是否发送成功，如不成功则跑出异常，让其执行异常处理里的函数
        request_json = r.json()
        errmsg = request_json[\'errmsg\']
        if errmsg != \'ok\':
            raise ValueError(\'发送告警微信失败!\')
        # 消息成功发送，停止死循环
        flag = False
    except Exception as e:
        print(e)
        access_token = get_access_token()

send_wx_alarm.py

 测试结果

[root@filestore-v2 ~]# python3 send_wx_alarm.py "arg1" "arg2" "arg3" #<==只接收第三个值
get success mp-TSxVbLrMC_L2OgB63LTIVxoWyyZ5IpmWwqdxnmsE3zdk0TFsB3o0Z20ar9FCziFv7zNtGIANbimMpEKPiFkfiaB_xYeIZl_dEkc_l6Pwl8jxcNd82my7I9Ry5ht4BYp9FzlT4V-Tc3wC9Qpt3vekaIiQxFtqPfDiA00TkXs5xcfPuNH6owb4_sqIdS7RmC1oWboloLANq7qdJxP6PRg
post success {"errcode":0,"errmsg":"ok","invaliduser":""} 

 

5、拷贝告脚本到zabbix服务外部脚本目录

#剪切到zabbix服务调用脚本的目录
[root@filestore-v2 ~]# mv send_wx_alerm.py /data/application/zabbix-4.4.3/share/zabbix/externalscripts/

#授权用户和组
[root@filestore-v2 ~]# chown zabbix.zabbix /data/application/zabbix-4.4.3/share/zabbix/externalscripts/send_wx_alarm.py 

#增加可执行权限
[root@filestore-v2 ~]# chmod 755 /data/application/zabbix-4.4.3/share/zabbix/externalscripts/send_wx_alarm.py 

#删除手动测试脚本产生的日志，这部很重要，如果临时文件是root的话，用zabbix用户永远是运行不的
[root@filestore-v2 ~]# rm -f /tmp/access_token.log 

 6、创建告警脚本

[root@filestore-v2 ~]# cat /data/application/zabbix-4.4.3/share/zabbix/alertscripts/send_wx.sh 
#!/bin/bash
#$1 : 发送相关人员
#$2 : 告警标题
#$3 : 告警内容
to=$1
subject=$2
body=$3
/usr/local/Python-3.6.6/bin/python3 /data/application/zabbix-4.4.3/share/zabbix/externalscripts/send_wx_alerm.py "$to" "$subject" "$body"

send_wx.sh

 

#授权用户
[root@filestore-v2 ~]# chown zabbix.zabbix /data/application/zabbix-4.4.3/share/zabbix/alertscripts/send_wx.sh 

#设置可执行权限
[root@filestore-v2 ~]# chmod 755 /data/application/zabbix-4.4.3/share/zabbix/alertscripts/send_wx.sh 

 7、创建【报警媒介类型】

7.1、【管理】=>【报警媒介类型】=>【创建媒体类型】

 

7.2、填写配置的数据，如下配置即可

{ALERT.SENDTO}
{ALERT.SUBJECT}
{ALERT.MESSAGE}

 

7.3、直接测试是否微信告警生效

 

开始下发微信告警内容

查看测试的结果
