What it is

Zipkin is a distributed tracing system that collects, stores, and visualizes timing data across microservice architectures to diagnose latency issues. It provides a web UI for querying traces by service, operation, tags, and duration, plus a dependency graph showing request flows between services. The project includes a standalone server (zipkin-server), multiple storage backends (Cassandra, Elasticsearch, in-memory), and collectors for ingestion via HTTP, Kafka, gRPC, and other protocols. Multi-module Maven monorepo: zipkin-server/ contains the main server executable, benchmarks/ holds JMH performance tests, .github/workflows/ defines CI/CD automation. Core tracing model in zipkin2…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone: git clone https://github.com/openzipkin/zipkin.git && cd zipkin. Build: ./mvnw clean install (Maven wrapper included in .mvn/). Run quick-start server: `curl -sSL https://zipkin.io/quickstart.sh | bash -s &&…

Daily commands:

Dev: ./mvnw clean package -DskipTests builds all modules. Start server: java -jar zipkin-server/target/zipkin-server-*.jar. Run benchmarks: ./mvnw -pl benchmarks clean package exec:exec@jmh. Tests: `./mvnw clean v…

…shortened for this brief.

Key cautions & unknowns

• JRE 17+ hard requirement (not 11 or 8). Maven wrapper required—don't use system Maven. Benchmarks module skipped on -DskipTests to prevent deployment. Elasticsearch and Cassandra dependencies managed separately in…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
