Zabbix Item and Trigger Setup Guide

Zabbix Item and Trigger Setup Guide

Setting up a Zabbix item and trigger is essential for monitoring your infrastructure efficiently. Zabbix offers powerful tools to create custom items and triggers that can track changes and send alerts in real-time. In this guide, we’ll show you how to create a Zabbix item and trigger, configure custom alerts, and streamline your monitoring processes. Additionally, we’ll explore how ZippyOPS services can help integrate DevOps, Cloud, and Automation into your workflows.

Creating a Zabbix Item

To begin, navigate to your desired host or template in Zabbix and follow these steps to create a Zabbix item:

1. Select Items > Create Item from the menu.
2. Choose Zabbix trapper as the item type. This will allow the item to send data to the server immediately, without waiting for polling intervals.
3. Fill in the details as follows:
   • Name: Test timestamp
   • Type: Zabbix trapper
   • Key: test.timestamp
   • Type of Information: Text
   • Enabled: Checked
4. Click Add to save the item.

Once created, this Zabbix item will store a text value, such as a timestamp, and send it to the server when updated.

Setting Up a Zabbix Trigger

The next step is to create a Zabbix trigger that will fire whenever the value of the timestamp changes. To set up the trigger:

1. Go to Triggers > Create Trigger.
2. Set up the trigger with these options:
   • Name: Timestamp changed
   • Expression: {[host/template]:test.timestamp.diff()}>0
     (Replace host/template with your actual host or template name)
   • Multiple PROBLEM events generation: Checked
   • Severity: Any (except Not classified)
3. Click Add to save the trigger.

This trigger will detect changes in the timestamp value and create a new event each time it changes.

Creating a Media Type for Custom Alerts

If you want to send custom alerts when your trigger state changes, you need to define a new media type. Follow these steps:

1. Go to Administration > Media Types > Create Media Type.
2. Choose the following options:
   • Type: Script
   • Script Name: Enter the filename of your custom alert script
   • Enabled: Checked
3. Click Add to save the media type.

By creating a custom media type, you can trigger scripts or notifications based on the Zabbix trigger’s state change.

Configuring an Action for Alerting

To automate notifications when the trigger is activated, you must create an action. Here’s how:

1. Navigate to Configuration > Actions > Create Action.
2. Enter the following details:
   • Name: Choose a meaningful action name
   • Subject: Set the default subject for the alert
   • Message: Set the default message for the alert
3. Under the Conditions tab, add a condition:
   • New Condition: Trigger = [dummy trigger]
     (Replace with the actual trigger name)
4. In the Operations tab, configure:
   • Send to Users: Select the user with the custom media type
   • Send Only To: Choose the custom media type you created
5. Click Add to save the action.

This action ensures that notifications are sent every time the trigger is activated.

Using Zabbix Sender to Simulate Events

To test the Zabbix item and trigger, use the zabbix_sender command. Here’s how to send a new value to trigger an event:

$ VALUE="$(date --rfc-3339=ns)"; zabbix_sender \
  --zabbix-server=127.0.0.1 \
  --host="Zabbix server" \
  --key="test.timestamp" \
  --value="${VALUE}"

To reset the trigger and generate a recovery message, send the same value again without modifying the VALUE variable:

$ zabbix_sender \
  --zabbix-server=127.0.0.1 \
  --host="Zabbix server" \
  --key="test.timestamp" \
  --value="${VALUE}"

This simulates both the Zabbix item and trigger change and recovery process.
