go-redis OpenTelemetry Monitoring with Uptrace

This example demonstrates how to instrument and monitor Redis operations in Go applications using OpenTelemetry and Uptrace, providing comprehensive observability into your Redis performance and operations.

Overview

This integration provides:

• Distributed tracing for Redis operations
• Performance monitoring with latency and throughput metrics
• Error tracking and debugging capabilities
• Visual dashboards for Redis health monitoring
• Production-ready observability stack with Docker

Prerequisites

• Go 1.19+
• Docker and Docker Compose
• Basic understanding of Redis and OpenTelemetry

Quick Start

1. Clone and Navigate

git clone https://github.com/redis/go-redis.git
cd example/otel

2. Start the Monitoring Stack

Launch Redis and Uptrace services:

docker compose up -d

This starts:

• Redis server on localhost:6379
• Uptrace APM on http://localhost:14318

3. Verify Services

Check that Uptrace is running properly:

docker compose logs uptrace

Look for successful startup messages without errors.

4. Run the Example

Execute the instrumented Redis client:

go run client.go

You should see output similar to:

trace: http://localhost:14318/traces/ee029d8782242c8ed38b16d961093b35

Click the trace URL to view detailed operation traces in Uptrace.

5. Explore the Dashboard

Open the Uptrace UI at http://localhost:14318 to explore:

• Traces: Individual Redis operation details
• Metrics: Performance statistics and trends
• Logs: Application and system logs
• Service Map: Visual representation of dependencies

Advanced Monitoring Setup

Redis Performance Metrics

For production environments, enable comprehensive Redis monitoring by installing the OpenTelemetry Collector:

The OpenTelemetry Collector acts as a telemetry agent that:

• Pulls performance metrics directly from Redis
• Collects system-level statistics
• Forwards data to Uptrace via OTLP protocol

When configured, Uptrace automatically generates a Redis dashboard:

Key Metrics Monitored

• Connection Statistics: Active connections, connection pool utilization
• Command Performance: Operation latency, throughput, error rates
• Memory Usage: Memory consumption, key distribution
• Replication Health: Master-slave sync status and lag

Logs and Debugging

View service logs:

# All services
docker compose logs

# Specific service
docker compose logs redis
docker compose logs uptrace
