Jaeger is a powerful distributed tracing system used to monitor and troubleshoot transactions in complex microservices environments. It tracks the path of requests as they flow through various services, helping you identify performance bottlenecks and understand request flows.

OpenTelemetry is a unified framework for collecting and transmitting telemetry data, including metrics, logs, and traces. By integrating Jaeger with OpenTelemetry, you can create a comprehensive observability solution that enhances your ability to monitor and analyze system performance.

Why Integrate Jaeger with OpenTelemetry?

Integrating Jaeger with OpenTelemetry allows you to leverage the strengths of both tools. OpenTelemetry collects and processes trace data, while Jaeger provides robust backend storage and visualization capabilities. 

This integration ensures that you can effectively monitor distributed systems, quickly identify issues, and improve performance.

Enhance with OpenObserve

To take your observability to the next level, consider integrating OpenObserve. OpenObserve complements Jaeger and OpenTelemetry by providing advanced visualization tools, comprehensive dashboards, and real-time analytics for tracing data. 

This combination ensures you have all the necessary tools to monitor, analyze, and optimize your distributed systems effectively.

Let's dive into the specifics of how to set up and configure the integration to maximize your observability capabilities.

OpenTelemetry Integration with Jaeger

Integrating Jaeger with OpenTelemetry Collector forms the backbone of a powerful observability setup.  

We'll explore the components involved and the steps needed to ensure a smooth integration.

Transition to a Robust Backend

With the discontinuation of Jaeger's experimental functionalities, it's essential to transition to an OpenTelemetry Collector-based backend.

This shift not only ensures stability but also leverages the latest advancements in telemetry data collection and processing.

Why Transition?

• Enhanced Stability: The OpenTelemetry Collector offers a stable, production-ready environment.
• Advanced Features: Benefit from the extensive features and continuous improvements in the OpenTelemetry ecosystem.
• Unified Data Pipeline: Integrates seamlessly with other telemetry data sources, providing a holistic observability solution.

Jaeger OpenTelemetry Backend Components

To facilitate this transition, Jaeger provides several backend components that work harmoniously with OpenTelemetry. Here’s a look at the key components:

Available Docker Images:

Jaeger offers Docker images that simplify the deployment process. These images encapsulate the necessary components, making it easy to get started.

jaeger-opentelemetry-agent:

The Jaeger OpenTelemetry Agent acts as a collector that receives trace data from your applications. It processes this data and forwards it to the Jaeger OpenTelemetry Collector.

jaeger-opentelemetry-collector:

This component aggregates the trace data from multiple agents and processes it before storing it in the backend. It’s designed to handle large volumes of trace data efficiently.

jaeger-opentelemetry-ingester:

The ingester component specifically handles the ingestion of trace data from the collector into your chosen storage backend.

All-in-One:

For testing and development, Jaeger provides an all-in-one Docker image that includes the agent, collector, and ingester in a single container. This setup is convenient for getting started quickly.

Example Docker Command:

Why These Components Matter

Utilizing these components ensures that your observability setup is robust and scalable. Each component is designed to handle specific tasks within the data pipeline, ensuring that trace data is collected, processed, and stored efficiently.

Key Benefits:

• Modular Architecture: Allows you to scale each component independently based on your needs.
• Efficiency: Optimizes the flow of trace data from collection to storage.
• Flexibility: Supports various deployment models, from development environments to production-scale systems.

Integrating Jaeger with OpenTelemetry through these backend components ensures a seamless and efficient observability setup. 

This integration not only enhances trace data collection and processing but also positions your system to leverage advanced features and continuous improvements from the OpenTelemetry community.

Compatibility

Integrating Jaeger with OpenTelemetry requires careful attention to compatibility details to ensure a smooth and efficient setup.  

Backward Compatibility with Jaeger Binaries

When transitioning to an OpenTelemetry Collector-based backend, maintaining backward compatibility with existing Jaeger binaries is crucial. This ensures that your current setup continues to function without disruptions.

Why It Matters:

• Smooth Transition: Avoids disruptions during the migration process.
• Operational Continuity: Ensures existing monitoring and tracing setups remain functional.
• Ease of Integration: Allows for incremental adoption of OpenTelemetry components.

Implementation:

• Use the jaeger-opentelemetry-collector which is designed to be compatible with older Jaeger binaries.
• Ensure that the collector can still ingest traces from Jaeger agents and client libraries without requiring changes to the existing setup.

OTLP Receiver Port (55680)

The OpenTelemetry Protocol (OTLP) receiver port is a critical configuration for the OpenTelemetry Collector. By default, the collector listens on port 55680 for incoming OTLP trace data.

Key Points:

• Default Port: 55680 is the standard port for OTLP receivers.
• Configuration: Ensure your network configurations allow traffic through this port.
• Security: Consider implementing security measures such as TLS to protect data transmitted over this port.

Configuration Example:

Health Check Port (13133)

To monitor the health and status of the OpenTelemetry Collector, the health check endpoint is exposed on port 13133. This allows you to verify that the collector is running correctly and receiving data.

Benefits:

• Operational Insight: Provides real-time health status of the collector.
• Troubleshooting: Helps in diagnosing issues by checking the collector’s operational status.
• Automation: Integrate health checks with automated monitoring systems for proactive alerts.

Configuration Example:

Metrics Exposure and Configuration Flags

Exposing metrics and using configuration flags effectively can optimize the performance and monitoring of your OpenTelemetry setup. These settings provide insights into the collector’s performance and help fine-tune the system.

Metrics Exposure:

• Visibility: Expose metrics to monitor the collector’s performance, resource usage, and data processing rates.
• Integration: Integrate with monitoring tools like Prometheus to visualize and analyze these metrics.

Configuration Flags:

• Custom Settings: Use configuration flags to tailor the collector’s behavior to your specific needs.
• Optimization: Adjust settings such as batching, queue size, and retry policies to enhance performance.

Configuration Example:

Ensuring compatibility when integrating Jaeger with OpenTelemetry involves understanding and configuring key components such as backward compatibility, OTLP receiver ports, health check endpoints, and metrics exposure. 

By paying attention to these details, you can achieve a seamless and efficient observability setup.

Configuration

Achieving optimal performance and comprehensive observability with Jaeger and OpenTelemetry requires meticulous configuration.  

Utilizing Jaeger Flags and OpenTelemetry Configuration

Combining Jaeger flags with OpenTelemetry configuration settings allows for a customized and efficient setup. Jaeger flags offer quick adjustments for tracing behavior, while OpenTelemetry configurations provide a structured approach to defining your observability pipeline.

Key Points:

• Jaeger Flags: Useful for quick, command-line based adjustments.
• OpenTelemetry Configuration: Offers a more detailed and comprehensive setup through configuration files.
