About
Jaeger is a distributed tracing platform released as open source by Uber Technologies . With Jaeger you can:
- Monitor and troubleshoot distributed workflows
- Identify performance bottlenecks
- Track down root causes
- Analyze service dependencies
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.
