High Availability Agent & Gateway Mode for the Opentelemetry Collector

This repository contains example code demonstrating how to implement high availability and gateway mode patterns with the OpenTelemetry Collector. The code shows how to:

• Set up redundant collectors for high availability
• Configure collectors in gateway mode to aggregate and forward telemetry data
• Handle failover between collectors
• Scale collectors horizontally

For a detailed walkthrough of the code and concepts, check out our blog post: Building Resilient Observability Pipelines with OpenTelemetry Collector HA & Gateway Mode (Note: Update with actual blog post URL)

Quick Start

The examples are organized into the following directories:

• /docker-nginx - High Availability collector configuration using Nginx as a load balancer in Docker Compose. (Architecture compatible with VMs)
• /docker-loadbalancing-exporter - High Availability collector configuration using the OpenTelemetry Collectors loadbalancing exporter as a load balancer in Docker Compose. (Architecture compatible with VMs)
• /k8s-loadbalancing - Native Kubernetes load balancing for High Availability collector configuration. (Real-life use case)

Each directory contains a README with specific setup instructions.

Prerequisites

• Docker and Docker Compose for running the local examples
• Two Kubernetes clusters for running the Kubernetes examples
• Basic familiarity with OpenTelemetry concepts
