Re-explain

Jaeger is an open-source, end-to-end distributed tracing system originally developed by Uber. It helps monitor and troubleshoot complex microservices architectures by tracking requests as they flow through multiple services.

Problems it solves:

  • Performance bottlenecks: Identifies slow services in request chains
  • Error tracking: Pinpoints where failures occur in distributed systems
  • Dependency analysis: Maps service interactions and dependencies
  • Root cause analysis: Helps debug issues across multiple services
  • Service optimization: Provides insights for performance improvements

Jaeger follows the OpenTracing standard and is now part of the Cloud Native Computing Foundation (CNCF).
