Zabbix implements email alerts

This article uses the 163 mailbox to implement the mailbox alarm of zabbix.
The prerequisite for realizing the alarm is to enable the IMAP/SMTP service of the 163 mailbox and record the authorization password. The operation is as follows:

1. Install the software on zabbix-server: mailx

[root@zabbix-server ~]# yum -y install mailx

2. Configure /etc/mail.re

[root@zabbix-server ~]# vim /etc/mail.rc

set from=yuzhang0304@163.com  #邮箱地址
set smtp=smtp.163.com
set smtp-auth-user=yuzhang0304@163.com  #邮箱地址
set smtp-auth-password=TKDXDXELOIKPQMCO  #邮箱地址授权密码
set smtp-auth=login

3. Test

Method 1: mailx -s "Mail title" Inbox Email < file containing the body
Method 2: cat file containing the body | mailx -s "Mail title" Inbox Email
Method 3: echo "Text content" | mailx - s "Email Title" Inbox Email
Method 4: mailx -s "Email Title" Inbox Email, press Enter and press CTRL+D to send

[root@zabbix-server ~]# mail -s "test1" [email protected] < /root/anaconda-ks.cfg
[root@zabbix-server ~]# cat /root/anaconda-ks.cfg | mail -s "tes2" [email protected]
[root@zabbix-server ~]# echo "hello" | mail -s "test3" [email protected]

4. Write a script to send emails on the zabbix-server side

[root@zabbix-server ~]# cd /usr/lib/zabbix/alertscripts/
[root@zabbix-server alertscripts]# vim sentmail.sh
[root@zabbix-server alertscripts]# chmod 777 sentmail.sh
[root@zabbix-server alertscripts]# chown zabbix:zabbix sentmail.sh

This script sends emails through method three. $3 represents the content of the email sent, $2 represents the email subject, and $1 represents the email address.

5. Complete the configuration of zabbix mailbox alarm on the web interface of zabbix-server

① Create alarm media

②Create action

Create an action to send an email and associate the action with a trigger (the trigger needs to be created in advance), that is, when the trigger is triggered, the email will be sent.

Action has been created

③Create a user and let the user associate the alarm media (the default user admin is used here)

6. Simulate faults according to the monitoring items corresponding to the triggers

What I use here is a trigger created in advance to monitor the running status of nginx. Close the nginx service in zabbix-agent to simulate a fault to trigger the trigger and send an email alert.

[root@zabbix-agent ~]# systemctl stop nginx

Alarm generated

Go to the mailbox to check the alarm information.

If you receive the alarm information, it means that zabbix has successfully implemented the mailbox alarm.
