How zabbix uses python script to send alarm emails

Preface

zabbix is ​​a very powerful monitoring tool that can monitor server data on Linux and Windows. You can also extend the default monitoring items through custom keys, but the information provided by the built-in email alarm is not Not very friendly. This article wants to use a custom script to send the corresponding image and URL connection at the same time as the alarm email.

The steps are as follows:

1. Edit the zabbix_server.conf file and modify the AlertScriptsPath parameter, which is used to specify the absolute path of the external script.

vim /etc/zabbix/zabbix_server.conf
AlertScriptsPath=/usr/lib/zabbix/alertscripts

2. Upload the new py script to the absolute path specified by the AlertScriptsPath parameter. The py file is as follows:

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

from email import encoders
from email.header import Header
from email.mime.text import MIMEText
from email.utils import parseaddr, formataddr
import smtplib
import sys
def send_mail(_to_email,_subject,_message):
# 定义邮件发送
 smtp_host = 'smtp.xxx.xx'
 from_email = 'xxx@xxx.xx'
 passwd = 'xxxxxx'
 msg = MIMEText(_message,'plain','utf-8')
 msg['Subject'] = _subject
 smtp_server = smtplib.SMTP(smtp_host,25)
 smtp_server.login(from_email,passwd)
 smtp_server.sendmail(from_email,[_to_email],msg.as_string())
 smtp_server.quit()
if __name__ == '__main__':
 send_mail(sys.argv[1],sys.argv[2],sys.argv[3])

3. Modify the permissions of the python script

chown -R zabbix:zabbix zabbix_send_email.py
chmod 755 zabbix_send_email.py

4. Zabbix web side configuration

Administration –> Media types –> Create media type

##Create a test user Administration –> ; Users –> Create user

Specify media for the newly created user:Administration –> Users –> Create user –> Media

Create action to implement email alarmConfiguration –> Actions –> Create action

5. Zabbix test sends emails

Find a test zabbix_agentd, kill it, and check whether you receive an alarm email. Restore it again and check whether you receive the restored email. If everything goes as expected, then you have completed using the python script to complete the zabbix alarm email. If it doesn't go as expected.

TIPS:

If you are using zabbix3.0, please note that the configuration of Administration –> Media types –> Create media type is as follows:
