Gotify Notifications for Zabbix

This GitHub repository contains a script for integrating Gotify to be able send notifications with Zabbix. Follow these instructions to set up and use the script with your Zabbix and Gotify instances.

Prerequisites

• Zabbix Server (version 5.0 or later recommended)
• Access to the Zabbix server with admin privileges
• A ready-to-use Gotify instance

Installation and Configuration

Step 1: Create an API Token in Gotify

Before setting up the script, you will need to create an application in Gotify to generate an API token.

1. Log into your Gotify server:

   • Login to the Gotify UI via your web browser.

2. Create a new application:

   • Navigate to the Apps section;
   • Press on Create App;
   • Enter the name for your application, for example Zabbix Notifications;
   • Press Create.

3. Copy the API Token:

   • Once the application is created, you'll see an API Token.
   • Copy this token as it will be used in the gotify.sh script.

Step 2: Customize and Deploy the Script

1. Clone the repository or download gotify.sh from this repository.

2. Edit gotify.sh to set up your Gotify server details:

   • Replace http://change.me with your Gotify server URL. For example, http://10.94.1.198 or https://gotify.example.com.

3. Copy the script to the Zabbix alertscripts directory, typically located at /usr/lib/zabbix/alertscripts/.

   sudo cp gotify.sh /usr/lib/zabbix/alertscripts/

4. Make the script executable:

   sudo chmod +x /usr/lib/zabbix/alertscripts/gotify.sh

Step 3: Configure Zabbix Media Type

1. Log into your Zabbix frontend.

2. Navigate to Administration > Media Types and click Create Media Type.

3. Select Script as the type and add a name, like Gotify.

4. For the script name, enter gotify.sh.

5. Define the following parameters:

   • {ALERT.SENDTO} - Gotify API Token
   • {ALERT.SUBJECT} - Notification subject
   • {ALERT.MESSAGE} - Notification message
   • {TRIGGER.SEVERITY} - Trigger severity (used to determine priority in Gotify)

6. Configure Message Templates:

   • Navigate to the Message templates tab.
   • Create templates for the different conditions under which notifications should be sent. Each template should specify the message format for the subject and body.

7. Save the new Media Type.

Step 4: Add Media to a Zabbix User

1. In Zabbix frontend, go to Administration > Users.

2. Edit the user who should receive Gotify notifications.

3. Under the Media tab, add the Gotify media type.

4. In the Send to field, enter your Gotify API Token.

5. Save the changes.

Step 5: Testing

Create a test trigger or wait for an actual alert to verify that notifications are being sent correctly to Gotify.

Note

• Ensure, that you have replaced http://change.me in the gotify.sh script with your actual Gotify server URL.
• The mapping between Zabbix severity levels and Gotify priorities can be adjusted within the script as per your requirements.
