About

Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It can be used for monitoring microservice-based architectures:

  • Distributed context propagation
  • Distributed transaction monitoring
  • Root cause analysis
  • Service dependency analysis
  • Performance / latency optimization

Jaeger is written in Go, with OpenTracing compatible client libraries available in Go, Java, Node and Python. It uses Cassandra for storage.

Features

  • OpenTracing compatible data model and instrumentation libraries
  • Backend components implemened in Go
  • React-based UI
  • Cassandra as persistent storage
  • Uses consistent upfront sampling with individual per service/endpoint probabilities
