About
Jaeger, inspired by Dapper and OpenZipkin , is a distributed tracing system released as open source by Uber Technologies . It is used for monitoring and troubleshooting microservices-based distributed systems, including:
- Distributed context propagation
- Distributed transaction monitoring
- Root cause analysis
- Service dependency analysis
- Performance / latency optimization
Uber published a blog post, Evolving Distributed Tracing at Uber , where they explain the history and reasons for the architectural choices made in Jaeger. Yuri Shkuro , creator of Jaeger, also published a book Mastering Distributed Tracing that covers in-depth many aspects of Jaeger design and operation, as well as distributed tracing in general.
Features

- Adaptive sampling
- Post-collection data processing pipeline (coming soon)
- Service Performance Monitoring (SPM)
See Features page for more details.
