Zabbix configures DingTalk's alarm function with pictures

Implementation ideas:

First of all, the alarm information must have itemid, which is a prerequisite. According to the parameters passed in the information, use regular matching to itemid to build a session, or use cookies to log in. Request pictures according to itemid and save the obtained pictures locally. Since the markdown picture link needs to be accessible, my zabbix is in the intranet, so the picture needs to be uploaded to the image bed or to a web server with a public network IP. I uploaded it to my personal server here. Convert the alarm information into markdown syntax format to construct a request. Use DingTalk's webhook to send messages and set up DingTalk robots

DingTalk robot needs to be set up for security. Here I define the keyword "notification", which means that the message sent must contain this keyword.

Script implementation: Since the image needs to be copied from the local to the remote, the password-free configuration needs to be done in advance. The script is executed by the zabbix user. It is best to set the security policy of the Web server directory.

Define the alarm media type. Open the Zabbix monitoring web, select Alarm Media Type in the Management menu, Create Media Type, select Script, fill in the name of the email with picture script just written, zabbix_email_pic.py, script parameters, and finally add

Open the user in the management, click the user for whom you want to set up email alerts, then add the alarm medium in the alarm medium, select the type you just defined in the pop-up box, customize the recipient, and finally add

Defining Alert Actions

Click on the action in the configuration menu, create an action, and then fill it out according to the picture.

Action Default Title Zabbix Notice: Server: {HOSTNAME} has: {TRIGGER.NAME} failure!
ITEMID:{ITEM.ID}
Alarm host:{HOST.NAME}
Alarm host:{HOST.IP}
Alarm time: {EVENT.DATE} {EVENT.TIME}
Alarm level:{TRIGGER.SEVERITY}
Warning information: {TRIGGER.NAME}
Alarm item:{TRIGGER.KEY}
Question details:{ITEM.NAME}:{ITEM.VALUE}
Current status:{TRIGGER.STATUS}:{ITEM.VALUE}
Event ID: {EVENT.ID}
Recovery operation Zabbix reported: Server: {HOST.NAME} occurred: {TRIGGER.NAME} has been restored!
ITEMID:{ITEM.ID}
Alarm host:{HOST.NAME}
Alarm host:{HOST.IP}
Alarm time: {EVENT.DATE} {EVENT.TIME}
Alarm level:{TRIGGER.SEVERITY}
Warning information: {TRIGGER.NAME}
Alarm item:{TRIGGER.KEY}
Question details:{ITEM.NAME}:{ITEM.VALUE}
Current status:{TRIGGER.STATUS}:{ITEM.VALUE}
Event ID: {EVENT.ID}

Final result

You can manually trigger an alarm to test the effect

At this point, Zabbix's WeChat, email, and DingTalk alarms with pictures have been configured.
