Introduction to Open Source Tracing with Jaeger and Zipkin

In the ever-evolving world of microservices and complex applications, monitoring performance becomes an intricate puzzle. Traditional monitoring tools often struggle to capture the intricate flow of requests across multiple services.

Enter distributed tracing – a revolutionary approach that sheds light on the entire journey of a request as it traverses your microservices landscape. By tracing each request's path, you gain a holistic view of application health and identify bottlenecks with pinpoint accuracy.

But when it comes to implementing distributed tracing, two open-source powerhouses emerge: Jaeger and Zipkin. Choosing the right tool can make a significant difference in your monitoring efficiency. This blog will equip you with the knowledge to navigate the Jaeger vs. Zipkin debate and select the perfect fit for your needs.

Fundamentals of Distributed Tracing

Here are the fundamentals of distributed tracing, with a focus on Jaeger and Zipkin:

Distributed Tracing and Its Necessity

Distributed tracing is a technique used to track the flow of requests across multiple services in a distributed system. It is necessary because modern applications are often composed of many microservices that communicate with each other over a network. Distributed tracing helps by providing a way to track the entire journey of a request, from start to finish, across all the services it touches.

Spans and Trace Context

In distributed tracing, a trace represents the end-to-end journey of a request through a distributed system. A trace is composed of one or more spans, where each span represents a single operation within the trace. Spans have several key attributes, including:

• Operation name: A string representing the name of the operation
• Start and end time: The start and end timestamps of the operation
• Tags: Key-value pairs that provide additional information about the span
• Logs: Timestamped events that provide more detailed information about the span

Trace context is used to propagate information about a trace across service boundaries. It typically includes a unique identifier for the trace, as well as the identifiers of the current span and parent span.

How Jaeger and Zipkin Implement Distributed Tracing

Jaeger and Zipkin are two popular open-source distributed tracing systems that implement the concepts of spans and trace context.

Jaeger

• Architecture: Jaeger uses a client library (called an agent) that runs alongside the application and collects trace data. The agent sends the data to a collector, which stores it in a backend storage system (such as Cassandra or Elasticsearch).
• Data Format: Jaeger uses a binary encoding format called Thrift for serializing and transmitting trace data.
• Query and Visualization: Jaeger provides a web-based user interface for querying and visualizing trace data.

Zipkin

• Architecture: Zipkin uses a similar architecture to Jaeger, with a client library (called a tracer) that collects trace data and sends it to a collector. The collector stores the data in a backend storage system (such as MySQL or Elasticsearch).
• Data Format: Zipkin uses JSON as its data format for serializing and transmitting trace data.
• Query and Visualization: Zipkin provides a web-based user interface for querying and visualizing trace data.

Both Jaeger and Zipkin support various programming languages and frameworks, making it easy to integrate distributed tracing into your application.

OpenObserve steps in as a powerful backend and front end solution. You do not need to manage and integrate multiple tools for traces if you use OpenObserve.

Instrumentation and Integration

Instrumentation Libraries and Their Role

Instrumentation libraries are software libraries that help you instrument your applications to collect telemetry data. These libraries provide APIs and tools to collect metrics, logs, and traces from the application. They play a crucial role in enabling distributed tracing and monitoring.

Comparing the Approach to Instrumentation by Jaeger and Zipkin

Jaeger and Zipkin are two popular open-source distributed tracing systems. Both tools provide instrumentation libraries to collect telemetry data from applications. However, they differ in their approach to instrumentation:

Jaeger: Jaeger uses a client library (called an agent) that runs alongside the application and collects trace data. The agent sends the data to a collector, which stores it in a backend storage system.

Zipkin: Zipkin uses a similar approach, but it uses a tracer library that collects trace data and sends it to a collector. The collector stores the data in a backend storage system.

Frameworks and Library Integration Support by Both Tools

Both Jaeger and Zipkin provide support for various frameworks and libraries to integrate with their instrumentation libraries:

Jaeger: Jaeger supports integration with various frameworks and libraries, including Java, Python, Go, and Node.js. It also provides support for popular frameworks like Spring Boot and Django.

Zipkin: Zipkin supports integration with various frameworks and libraries, including Java, Python, Go, and Node.js. It also provides support for popular frameworks like Spring Boot and Django.

This highlights the role of instrumentation libraries in distributed tracing and monitoring, as well as the differences in approach between Jaeger and Zipkin.

Sampling Strategies and Data Model

Jaeger's Adaptive Sampling and Zipkin's Per-Service Sampling

Jaeger and Zipkin have different approaches to sampling in distributed tracing:

Jaeger: Jaeger uses adaptive sampling, which dynamically adjusts the sampling rate based on the volume of incoming data. This allows for more efficient data collection and reduces the risk of overwhelming the storage system.

Zipkin: Zipkin uses per-service sampling, which sets a fixed sampling rate for each service. This approach is simpler and easier to implement but may not be as efficient as Jaeger's adaptive sampling.

Jaeger and Zipkin's Differing Approaches to the Data Model

Jaeger and Zipkin have different data models:

Jaeger: Jaeger uses a more complex data model that includes concepts like spans, traces, and services. This allows for more detailed and nuanced analysis of the distributed tracing data.

Zipkin: Zipkin uses a simpler data model that focuses on tracing and spans. This approach is easier to implement but may not provide the same level of detail as Jaeger's data model.

Importance of Sampling in Distributed Tracing and Implications for Data Collection

Sampling is crucial in distributed tracing because it helps to reduce the volume of data collected and stored. This is important because:

Data Volume: Distributed tracing can generate a large volume of data, which can overwhelm storage systems and make analysis difficult.

Data Quality: Sampling helps to ensure that the data collected is representative of the overall system behavior and not just a small subset of the data.

Data Storage: Sampling reduces the amount of data stored, which can help to reduce storage costs and improve data retrieval times.

In summary, Jaeger's adaptive sampling and Zipkin's per-service sampling are two different approaches to sampling in distributed tracing. Jaeger's data model is more complex and nuanced, while Zipkin's data model is simpler and easier to implement. Sampling is important in distributed tracing because it helps to reduce the volume of data collected and stored, ensuring data quality and reducing storage costs.
