Jaeger Has a Free API: Distributed Tracing for Microservices

Jaeger is an open-source distributed tracing platform. It monitors and troubleshoots transactions in complex distributed systems, helping you find bottlenecks, trace requests across services, and debug latency issues. What Is Jaeger? Jaeger is a CNCF graduated project originally built by Uber. It collects distributed traces from microservices and provides a UI to visualize request flows, identify slow services, and analyze dependencies. Key Features: Distributed context propagation Service dependency analysis Root cause analysis Adaptive sampling Multiple storage backends (Cassandra, Elasticsearch, Kafka) OpenTelemetry native support REST and gRPC API Service performance monitoring Quick Start # All-in-one (dev/testing) docker run -d --name jaeger -p 16686:16686 -p 4317:4317 -p 4318:4318 \ jaegertracing/all-in-one:latest # UI at http://localhost:16686 Instrument Your App from opentelemetry import trace from opentelemetry.sdk.trace import TracerProvider from opentelemetry.sdk.trace.expo
