Zabbix GraphQL API

A modern GraphQL interface for Zabbix, providing enhanced features and easier integration for automation and management.

Purpose

The Zabbix GraphQL API acts as a wrapper and enhancer for the native Zabbix JSON-RPC API. It simplifies complex operations, provides a strongly-typed schema, and adds advanced logic for importing, querying, and managing Zabbix entities like hosts, templates, and user rights.

🚀 Features

• GraphQL Interface: Modern GraphQL API wrapping Zabbix functionality

  • Reference: schema/queries.graphql, schema/mutations.graphql, src/api/start.ts

• Hierarchical Data Mapping: Automatic mapping of Zabbix items/tags to nested GraphQL objects

  • Reference: src/api/resolver_helpers.ts, schema/device_value_commons.graphql, docs/sample_all_devices_query.graphql

• Mass Operations: Import/export capabilities for hosts, templates, and user rights

  • Reference: schema/mutations.graphql (importHosts, importTemplates, importUserRights, etc.), docs/sample_import_*.graphql

• Dynamic Schema Extension: Extend the schema without code changes using environment variables

  • Reference: src/api/schema.ts, schema/extensions/, src/common_utils.ts (ADDITIONAL_SCHEMAS, ADDITIONAL_RESOLVERS)

• Permission System: Role-based access control using Zabbix template groups

  • Reference: schema/api_commons.graphql (Permission enum, PermissionRequest), src/api/resolvers.ts (hasPermissions, userPermissions), docs/sample_import_permissions_template_groups_mutation.graphql

• Type Safety: Full TypeScript support with generated types

  • Reference: codegen.ts, src/schema/generated/graphql.ts, tsconfig.json, package.json (devDependencies for GraphQL Codegen)

• AI Agent & MCP Enablement: Native support for Model Context Protocol (MCP) and AI-driven automation. GraphQL's strongly-typed, introspectable nature provides a superior interface for AI agents compared to traditional REST APIs.

  • Reference: docs/howtos/mcp.md, mcp-config.yaml, docker-compose.yml (MCP service)

How to Install and Start

Prerequisites

• Node.js: Version 24 (LTS) or higher recommended.
• Zabbix: A running Zabbix instance (compatible with Zabbix 6.0+).

Installation

1. Clone the repository:

   git clone <repository-url>
   cd zabbix-graphql-api
   

2. Install dependencies:

   npm install
   

⚙️ Configuration

Environment Variables

The API is configured via environment variables. Create a .env file or set them in your environment:

Variable	Description	Default	Required
ZABBIX_BASE_URL	URL to your Zabbix server (include /zabbix path)	-	Yes
ZABBIX_PRIVILEGE_ESCALATION_TOKEN	Zabbix Super Admin API token used for privilege escalation (e.g. during import operations)	-	Yes
ZABBIX_DEVELOPMENT_TOKEN	Token used ONLY for local development and isolated testing to simulate a "real end user"	-	No
ZABBIX_EDGE_DEVICE_BASE_GROUP	Base group for edge devices	Roadwork	No
ZABBIX_PERMISSION_TEMPLATE_GROUP_NAME_PREFIX	Prefix for permission template groups (used to identify permission-related template groups in Zabbix)	Permissions	No
SCHEMA_PATH	Path to schema files	./schema/	No
ADDITIONAL_SCHEMAS	Comma-separated list of additional schema files	-	No
ADDITIONAL_RESOLVERS	Comma-separated list of resolver types to generate	-	No
LOG_LEVEL	Log level configuration (e.g. debug, info, warn, error)	info	No
HOST_TYPE_FILTER_DEFAULT	Default filter for host types	-	No
HOST_GROUP_FILTER_DEFAULT	Default filter for host groups	-	No

🔐 Authorization

The application operates with different authentication and authorization mechanisms depending on the scenario:

1. Production Use

In production environments, the ZABBIX_DEVELOPMENT_TOKEN should always be unset to ensure proper security.

• Zabbix Frontend Widgets: When accessing the API from widgets embedded in the Zabbix frontend, no static token is needed. Authentication is automatically derived from the zbx_session cookie provided by the Zabbix web login, which is forwarded to the Zabbix API.
• Other Production Tools: For other purposes (e.g. accessing the API from external tools or scripts), a Zabbix session or auth token must be passed via the zabbix-auth-token HTTP header.

2. Privilege Escalation

• ZABBIX_PRIVILEGE_ESCALATION_TOKEN: Certain operations, such as importing hosts, templates, or user rights, require Super Admin access to Zabbix for specific parts of the process. This token allows the API to perform these administrative tasks even when the initiating user does not have Super Admin rights themselves.

3. Local Development and Testing

• ZABBIX_DEVELOPMENT_TOKEN: This environment variable is intended only for local development and isolated testing. It allows developers to "simulate" a Zabbix access token representing a "real end user" without needing to provide the HTTP header in every request.
  • Warning: This should be avoided in production as it undermines security by bypassing per-request authentication.

Zabbix to GraphQL Mapping

The API maps Zabbix entities to GraphQL types as follows:

Zabbix Entity	GraphQL Type	Description
Host	Host / Device	Represents a Zabbix host; Device is a specialized Host with a deviceType tag
Host Group	HostGroup	Represents a Zabbix host group
Template	Template	Represents a Zabbix template
Template Group	HostGroup	Represents a Zabbix template group
Item	Nested fields	Zabbix items become nested fields based on their key names (hierarchical mapping)
Tag	Tag	Represents a Zabbix tag associated with a host or template
Inventory	Location	Host inventory information maps to location data

Starting the API

Development Mode

Starts the server with nodemon and tsx for automatic reloading:

npm run start

Production Mode

Builds the project and runs the compiled code:

npm run prod

The API will be available at http://localhost:4000/.

Running with Docker

Using the Pre-built Image

You can run the API without building it locally by pulling the latest image from the Hilbig IT Forgejo infrastructure:

docker pull forgejo.tooling.hilbigit.com/zabbix/zabbix-graphql-api:latest

Start the container by passing the required environment variables:

docker run -d \
  --name zabbix-graphql-api \
  -p 4000:4000 \
  -e ZABBIX_BASE_URL=http://your-zabbix-instance/zabbix \
  -e ZABBIX_PRIVILEGE_ESCALATION_TOKEN=your-super-admin-token \
  forgejo.tooling.hilbigit.com/zabbix/zabbix-graphql-api:latest

Building Locally

If you prefer to build the image yourself using the provided Dockerfile:

1. Build the image (ensure you provide an API_VERSION):

   docker build -t zabbix-graphql-api --build-arg API_VERSION=1.0.0 .
   

2. Run the container:

   docker run -d \
     --name zabbix-graphql-api \
     -p 4000:4000 \
     -e ZABBIX_BASE_URL=http://your-zabbix-instance/zabbix \
     -e ZABBIX_PRIVILEGE_ESCALATION_TOKEN=your-super-admin-token \
     zabbix-graphql-api
   

Sample Application: Virtual Control Room (VCR)

The Virtual Control Room (VCR) is a professional cockpit and control center application designed for monitoring and managing large-scale deployments of IoT and Edge devices, such as traffic management systems, roadwork safety equipment, and environmental sensors.

How VCR uses the GraphQL API:

• Unified Cockpit: VCR utilizes the API's hierarchical mapping to provide a unified view of diverse device types. It maps Zabbix items and tags directly to structured GraphQL objects (e.g. operational telemetry and current business state).
• Dynamic Authorization: The hasPermissions query is used to implement a Dynamic UI. Buttons, controls, and status indicators are shown or enabled only if the user has the required READ or READ_WRITE permissions for that specific object.
• Mass Provisioning: VCR leverages the mass import capabilities to provision thousands of devices and templates in a single operation, significantly reducing manual configuration effort in Zabbix.
• Data Visualization: It uses the exportHostValueHistory endpoint to power dashboards showing historical trends, such as traffic density, battery levels, or sensor readings over time.

🔄 API Version

The API version is automatically set during the Docker build process based on the Git tag or commit hash. This version information is embedded into the Docker image and becomes accessible through the API_VERSION environment variable at runtime.

Zabbix Version Compatibility

This API is designed to work with Zabbix 7.4, which is the version it runs productively with. While it may work with earlier versions (like 6.0+), 7.4 is the officially supported and tested version.
