# Kafka Significant Events

> Available since: version 7.0.1

## Overview

The Kafka Significant Events are a centralized event system in the MetalSoft platform that emit structured events to Kafka for external integration. These events capture critical infrastructure changes and security actions across the platform and allow 3rd party developers and clients to develop integrations with other enterprise systems and automation solutions.

## Architecture

### Components

1. **Event Categories**
   - **Server Management**: Server lifecycle events (creation, updates, deletion, registration)
   - **Security**: User and authentication events (login, credential changes, access modifications)
   - **Network Device Management**: Network infrastructure events (device registration, fabric assignments)
   - **Instance Management**: Instance and DNS lifecycle events (updates, deletions)

### Event Structure

Each significant event follows the CloudEvent specification and contains the following structure:

```json
{
  "id": "unique-event-identifier",
  "time": "2025-01-01T12:00:00.000Z",
  "type": "dot.separated.event.type",
  "source": "https://metalsoft.io/microservice-name",
  "specversion": "1.0",
  "datacontenttype": "application/json",
  "data": {
    // Event-specific payload with string values
  }
}
```

## Event Data Examples

**Note**: All examples below show the complete CloudEvent format as it appears in Kafka. Each event includes the CloudEvent metadata (`id`, `time`, `type`, `source`, `specversion`, `datacontenttype`) and the event-specific data in the `data` field. Numeric values are serialized as strings in the JSON format.
