Zipkin Technology Intelligence

What is Zipkin?

Zipkin is a distributed tracing system that helps gather timing data needed to troubleshoot latency problems in microservice architectures. It was originally developed by Twitter and is now a fully open-source project used widely in the Java ecosystem and beyond.

Zipkin collects trace data via instrumented libraries or OpenTelemetry exporters, stores it, and provides a web UI for viewing traces and service dependencies. It's known for its simplicity and ease of integration with Spring Cloud and other frameworks.

Detection of Zipkin indicates distributed tracing implementation, commonly found in Java/Spring environments, microservices architectures, and organizations seeking a straightforward, proven tracing solution.

Zipkin Integration Examples

Spring Boot Configuration

# application.yml
spring:
  application:
    name: my-service
  zipkin:
    base-url: http://zipkin:9411
  sleuth:
    sampler:
      probability: 1.0

Docker Quick Start

# Run Zipkin with in-memory storage
docker run -d -p 9411:9411 openzipkin/zipkin

# With Elasticsearch storage
docker run -d -p 9411:9411 \
  -e STORAGE_TYPE=elasticsearch \
  -e ES_HOSTS=http://elasticsearch:9200 \
  openzipkin/zipkin

Manual Span Creation (Java)

Span span = tracer.nextSpan().name("my-operation").start();
try (Tracer.SpanInScope ws = tracer.withSpanInScope(span)) {
    // Your code here
    span.tag("user.id", userId);
} finally {
    span.finish();
}
