Before configuring alerts, the host group should be present and must contain some hosts with Zabbix agents installed on them.

Type: Email
Email provider: Generic SMTP
SMTP server: <server IP or Domain>
SMTP server port: <port>
Email: <email>
Authentication: Username and Password
Username: <username>
Password: <password>
Message format: Plain Text
  • After creating the new media type, click on Test, which is on the far right
  • Test the new media type by providing the required details (Send to, Subject, etc.)
  • If the test is successful, you will see the Media type test successful. prompt

User Group Permission

To send alerts to a particular user, the user must be created and a media type must be assigned. The user must also be part of a user group.

  • Select Host permissions tab
  • In the Permissions section, add the required host group and click Update to finalize the changes

Conditions: 
          condition1: Trigger severity is greater than or equals Average
          Condition2: Host group equals <host group>
  • Navigate to Operations tab
  • in Operations section, select Add
  • The Operation details box opens, Select the Send to users and Send to media type as per requirement.
  • In Recovery options Click Add and select Notify all involved and click OK
  • click on OK/Update to finalize the changes

Testing the Alerts

To test the alerts, create a test host in the host group. After a few minutes, the test host will generate an error stating “Zabbix agent is not available.” Follow the steps below to verify whether the alert is sent:

  • Navigate to Reports > Action log
  • Select "Last 5 Minutes" on the top right corner to view the logs easily
