How to Send Zabbix Alerts with Images to DingTalk via Python

Implementation Idea

First, the alert must contain an

itemid

; use a regular expression to extract it.

Build a session or use cookies to log in, request the chart image using the

itemid

, save it locally, then upload it to a public web server so the markdown image link can be accessed.

Convert the alert information to markdown format.

Construct a request to send the message via DingTalk webhook.

Configure DingTalk Robot

DingTalk robot requires security settings; define a keyword “通知” so that messages must contain this word.

Script Implementation

Because the image must be copied to a remote server, set up password‑less SSH in advance; the script runs as the Zabbix user, and the web server directory should have appropriate security policies.

<code>#!/usr/bin/python
# -*- coding: utf-8 -*-
import requests,time
import json,sys,re,os

zabbixserver_url ='http://192.168.99.200/index.php'
# Define remote web server address for image copy
pname_path='http://47.103.15.51/dingding_pic/'
# URL to get the chart image
testUrl = "http://192.168.99.200/chart.php"
host='192.168.99.200'

def get_itemid():
    itemid=re.search(r'ITEM ID:(\d+)',sys.argv[2]).group(1)
    return itemid

    myRequests = requests.Session()
    try:
        loginHeaders = {

        testUrlplayLoad = {

           "itemids": itemid,
           "width": "700",
        }
        testGraph =  myRequests.get(url=testUrl,params=testUrlplayLoad)
        IMAGEPATH = os.path.join('/usr/lib/zabbix/alertscripts/dingding_pic/', pname)
        with open(IMAGEPATH,'wb') as f:
            f.write(testGraph.content)
        os.system("sudo scp %s [email protected]:/usr/share/nginx/html/dingding_pic" %IMAGEPATH)
        pname_url = pname_path+pname
        return pname_url
    except Exception as e:
        print(e)
        return False

def send_msg(pname_url,info3):
    headers = {'Content-Type': 'application/json;charset=utf-8'}
    print(info3)
    data = {
        "msgtype": "markdown",
        "markdown": {
            "title": info1,
            "text": "## 通知:\n"+info3+"![screenshot](%s)\n"%(pname_url)
        },
        "at":{
            "atMobiles": reminders,
            "isAtAll": False,
        },
        }
    r = requests.post(url=webhook_url,json=data,headers=headers)
    print(r.text)

def info_text():
    new_text = ""
    x = info2.split('\n')
    for i in x:

            pass
        else:
            new_text+="- "+str(i)+('\n')
    print(type(new_text))
    return new_text

if __name__ == '__main__':
    os.system("echo hello >> /tmp/syslog.md")
    pname = str(int(time.time()))+'.png'
    info1 = str(sys.argv[1])
    info2 = str(sys.argv[2])
    info3 = info_text()
    with open('/tmp/syslog.md','a') as f:
        f.write(info1)
        f.write(info2)
        f.close()
    reminders = []
    webhook_url = 'https://oapi.dingtalk.com/robot/send?access_token=...'
    itemid = get_itemid()
    pname_url=get_picture(itemid,pname)
    print(pname_url)
    send_msg(pname_url,info3)

Define Alert Media Type

In the Zabbix web UI, go to Administration → Media types, create a new media type of type “Script”, set the script name to the Python file (e.g.,

zabbix_email_pic.py

), configure the script parameters, and save.

Define Alert Action

Navigate to Configuration → Actions, create a new action, and use the image‑based message template.

<code>操作
默认标题 Zabbix告警：服务器:{HOSTNAME}发生: {TRIGGER.NAME}故障!
ITEMID:{ITEM.ID}
告警主机:{HOST.NAME}
告警主机:{HOST.IP}
告警时间:{EVENT.DATE} {EVENT.TIME}
告警等级:{TRIGGER.SEVERITY}
告警信息: {TRIGGER.NAME}
告警项目:{TRIGGER.KEY}
问题详情:{ITEM.NAME}:{ITEM.VALUE}
当前状态:{TRIGGER.STATUS}:{ITEM.VALUE}
事件ID:{EVENT.ID}
恢复操作
Zabbix告警：服务器:{HOST.NAME}发生: {TRIGGER.NAME}已恢复!
ITEMID:{ITEM.ID}
告警主机:{HOST.NAME}
告警主机:{HOST.IP}
告警时间:{EVENT.DATE} {EVENT.TIME}

告警项目:{TRIGGER.KEY}
问题详情:{ITEM.NAME}:{ITEM.VALUE}
当前状态:{TRIGGER.STATUS}:{ITEM.VALUE}

</code>

Final Result

Trigger a test alarm to see the image‑included notification in DingTalk, email, or WeChat.

All three channels are now configured to receive Zabbix alerts with pictures.
