Introduction

Radar Collector collects Redis metrics from configured deployments and sends them to the Radar server via gRPC.

Supported Deployment Types

• Standalone Redis instances
• Redis Enterprise clusters (REST API integration)
• Redis Cluster (OSS) with automatic node discovery
• Redis Sentinel

Features

• Monitor multiple Redis deployments from a single collector
• YAML configuration with environment variable expansion
• Offline collection mode with configurable data redaction
• gRPC communication with API key authentication
• Configuration validation and connection testing
• Signal handling for graceful shutdown (SIGINT, SIGTERM)
• Configurable logging levels with JSON output option

Quick Start

1. Install the radar-collector binary
2. Configure your Redis deployments
3. Validate your configuration
4. Run the radar-collector

Architecture

Single-binary design with:

• Configuration layer - YAML parsing with environment variable expansion
• Collection layer - Per-deployment type collectors
• gRPC layer - Communication with Radar server
• Redaction layer - Privacy controls for sensitive data
