many others<\/a>. This tutorial will show you how to configure email notifications.<\/p>\nSetting up your Email<\/h1>\n
To set up email notifications, click on Administration<\/strong> on the Lefthand menu of the Zabbix web interface, then click Media Types<\/strong>. Then click on Email<\/strong>.<\/p>\nYou can adjust the SMTP options to match the settings of your email service. This tutorial will use Gmail's SMTP.<\/p>\n
Gmail users should type in smtp.gmail.com<\/code> in the SMTP server<\/strong> field. 465<\/code> for the SMTP port<\/strong> field. gmail.com<\/code> for the SMTP helo<\/strong>. Then add your email address in the SMTP email<\/strong> field. Next, choose SSL\/TLS<\/strong> for the Connection security<\/strong> field, and Username and password<\/strong> for Authentication<\/strong>. Type in your email address for the Username<\/strong> field, and for the Password<\/strong> field, enter your Google App Password<\/strong>. Click Update<\/strong> as a final step.<\/p>\nYou can now test sending notifications.<\/p>\n
Click the Test<\/strong> underlined button.<\/p>\nA pop-up window will appear. Enter your email address into the Send to<\/strong> field, then click Test<\/strong>. You should receive a test successful message<\/strong> at the top of the widget.<\/p>\nClose the pop-up by clicking the Cancel<\/strong> button.<\/p>\nNext, create a new user. In the left navigation bar, click on Administration<\/strong> and then Users<\/strong>. A list of users will appear. Next, click on the Create user<\/strong> button at the top-right corner of your screen.<\/p>\nIn the Alias<\/strong> field, enter your username and create a new password. Next, add this user to the administrator\u2019s group. In the Groups field, type in Zabbix administrators<\/strong> and then select the group from the list.<\/p>\nNext, in the Media<\/strong> tab, click on the Add<\/strong> underlined link. A pop-up titled Media<\/strong> should appear.<\/p>\nChoose the Email<\/strong> option from Type<\/strong> drop-down menu. In the Send to<\/strong> box, enter your email address. The rest of the options can be left as is. Finally, click the Add<\/strong> button.<\/p>\nNext, in the Permissions<\/strong> tab. From the User type<\/strong> drop-down menu, select Zabbix Super Admin<\/strong>. Then click Add<\/strong> to create the user.<\/p>\nWarning:<\/h4>\n
Using the default password is not safe. In order to change the password of the built-in user 'Admin' click on it. Then click 'Change password'.<\/strong><\/p>\nYou will now need to enable notifications. Click on the Configuration<\/strong> tab, then click on Actions<\/strong>. A pre-configured action will appear. This will allow you to send notifications to all Zabbix administrators. Click on the name to review and modify its settings. The default parameters will be used for this tutorial. To enable it, click on the Disabled<\/strong> button in the Status<\/strong> column.<\/p>\nYou are now ready to start receiving alerts.<\/p>\n
Generating and Sending an Email Test Alert<\/h1>\n
This step will create a test alert that verifies everything is connected. We will create a large file that triggers a notification, because Zabbix automatically tracks the free space on your server. The check takes place every hour, so it may take a while before the notification is triggered.<\/p>\n
Make a temporary file large enough to trigger Zabbix\u2019s file system usage alert.<\/p>\n
Log in to your monitored server with SSH, then, find out how much space you have left on your server using df<\/code>:<\/p>\ndf -h<\/code><\/pre>\nThe command df<\/code> will show you how much your file system is using in terms of disk space. The -h<\/code> tells df<\/code> to show human-readable output:<\/p>\nFilesystem Size Used Avail Use% Mounted on\n\/dev\/vda1 38G 1G 37G 2% \/<\/code><\/pre>\nHere, the free space is 37 GB. So, to trigger a Zabbix you can use the fallocate<\/code> command to create a large temporary file that takes up 35 GB of your disk space:<\/p>\nfallocate -l 35G \/tmp\/temp.img<\/code><\/pre>\nZabbix will send you an alert about the amount of free disk space and it will run the action which you configured for sending the notification message. This may take about an hour. You can check your inbox for the message from the Zabbix server, and you should see a warning message that tells you that your disk space is low.<\/p>\n
To view the notification and details, you can also navigate to the Zabbix Dashboard<\/strong> and the Monitoring<\/strong> tab.<\/p>\nYou can then delete the test file to free up space on you server:<\/p>\n
rm -f \/tmp\/temp.img<\/code><\/pre>\nThis should make the alert disappear on the Zabbix web interface.<\/p>\n
Congrats<\/h2>\n
