Zabbix GraphQL API Cookbook

This cookbook provides step-by-step "recipes" for common tasks. These instructions are designed to be easy for humans to follow and structured enough for AI agents (using the MCP server) to generate test cases.

🤖 AI-Based Test Generation

To generate a test case from a recipe:

1. Start the zabbix-graphql MCP server.
2. Provide the recipe to your AI agent.
3. Ask the agent to "Implement a test case for this recipe using the Zabbix GraphQL API".
4. The agent will use the MCP server to explore the schema and generate appropriate GraphQL operations.

🍳 Recipe: Extending Schema with a New Device Type

This recipe shows how to add support for a new specialized device type without modifying the core API code.

Prerequisites

• Zabbix Template Group Templates/Roadwork/Devices exists.
• Zabbix GraphQL API is running.

Step 1: Define the Schema Extension

Create a new .graphql file in schema/extensions/ (e.g. distance_tracker.graphql):

type DistanceTrackerDevice {
  id: String
  name: String
  location: Location
  distance: Float
  batteryLevel: Float
  lastSeen: DateTime
}

Step 2: Configure Environment Variables

Add the new schema and resolver to your .env file:

ADDITIONAL_SCHEMAS=./schema/extensions/distance_tracker.graphql
ADDITIONAL_RESOLVERS=DistanceTrackerDevice

Restart the API server.

Step 3: Import the Template

Execute the importTemplates mutation to create the template in Zabbix. Use Zabbix item keys that match your GraphQL fields (e.g. distance.current for distance).

🍳 Recipe: Provisioning a New Host

Prerequisites

• A target Host Group exists in Zabbix.
• At least one Template exists in Zabbix.

Step 1: Prepare the Host Object

Define the host name, groups, and templates to link.

Step 2: Execute createHost Mutation

mutation CreateNewHost($host: String!, $groups: [Int!]!, $templates: [Int!]!) {
  createHost(host: $host, hostgroupids: $groups, templateids: $templates) {
    hostids
    error {
      message
    }
  }
}

🍳 Recipe: Managing User Permissions

Step 1: Create Permission Template Group

Create a template group with the prefix Permissions/ in Zabbix (e.g. Permissions/Read-Only-Access).

Step 2: Assign to User Group

In Zabbix, give a User Group Read access to this template group.

Step 3: Verify via API

query CheckMyPermissions {
  hasPermissions(permissions: [
    { objectName: "Read-Only-Access", permission: READ }
  ])
}
