zabbix uses 163 mailboxes to monitor alarms

- Management—Alarm Media Type—Create Media Type
- Here we select the email type of email alarm
- Management—Alarm Media Type—Create Media Type
- Set recipient
- Click User—Alarm Media—Add Alarm Media
- Generally speaking, it is necessary to create a new user group, such as a development group, an operation and maintenance group, after creating a user group, create a user, set the alarm medium in the user settings
- Click User—Alarm Media—Add Alarm Media
- Start action
- Configure-Action-Enable Action
- The default action is effective for the administrator group, so you need to create a new action

- Set the alarm content for people to move
2. Use 163 mailbox to alarm
2.1. Define the sender
Management—Alarm Media Type—Create Media Type

- Type select email
- The smtp server address can be checked at 163, the default is smtp.163.com
- Port is 25
- smtp helo is the second-level domain name
- smtp email: fill in which email address to send emails
- Select None for the security link, if it is QQ alarm, check ssl/tls
- Authentication select user name and password
- User name fill in 163 email account
- Password fill in the client authorization code KTTHQZHWIICEIMOA

3. Test whether an alarm email can occur
Set the maximum number of terminal open triggers for the 192.1.81.230 host
Trigger an alarm
The alarm has been triggered, check the email
Problem occurs
Problem recovery
4. Add monitoring items for host downtime detection and trigger alarm
4.1. Add ping monitoring items
For this kind of ping monitoring, it is generally necessary to monitor on zabbix-server, because when the server is down, the agent will not be detected. It can only be detected on zabbix-server
1.编写脚本
[root@zabbix-server ~]# vim /etc/zabbix/scripts/ping.sh
#!/bin/bash
ping -c3 192.168.81.230 &>/dev/null
echo $?
2.创建自定义监控项key
[root@zabbix-server ~]# vim /etc/zabbix/zabbix_agentd.d/user_monitor.conf
UserParameter=192_168_81_230_ping_host,sh /etc/zabbix/scripts/ping.sh
3.重启zabbix agent
[root@zabbix-server ~]# systemctl restart zabbix-agent
4.zabbix-server测试监控项
[root@zabbix-server ~]# zabbix_get -s 127.0.0.1 -k 192_168_81_230_ping_host
0
4.2. New monitoring items on the page
Configuration-host-monitoring item-new monitoring item
Fill in the key-value application set
- Name: 192.168.81.230-Host survival detection
- Key value: 192_168_81_230_ping_host
- Application set: host survival detection
4.3. Page creation trigger
Configuration—Host—Trigger—New Trigger
{Zabbix server:192_168_81_230_ping_host.last()}>1
Zabbix serve 监控主机
192_168_81_230_ping_host 监控项
last()}>1 最后一个值
Created successfully
Trigger has been bound to the item
4.4. Trigger an alarm
关掉服务器即可
[root@192_168_81_230 ~]# poweroff
5. Another host computer downtime monitoring alarm
5.1. Create a host down trigger
Trigger host down alarm by setting agent.ping monitoring items
Just create a new trigger
The expression is as follows: {Template OS Linux system:agent.ping.nodata(20m)}=1
The meaning of this expression is to trigger a downtime alarm if the result is always 1 within 20 minutes
Expression generation:
Set trigger information
5.2. Trigger an alarm and check email
关掉服务器即可
[root@192_168_81_230 ~]# poweroff
5.3. View alarm mail
Failure occurred
Recovery
