Jaeger is an open-source, end-to-end distributed tracing system designed to monitor and troubleshoot complex, microservices-based architectures. Originally developed by Uber and now a part of the Cloud Native Computing Foundation (CNCF), Jaeger provides powerful tools for visualizing and analyzing the flow of requests across distributed systems. It helps identify performance bottlenecks, latency issues, and errors, making it essential for developers and DevOps teams managing modern, cloud-native applications.
Core Features
Distributed Tracing: Tracks the lifecycle of a request across multiple services, enabling detailed visibility into system interactions.
Performance Metrics: Measures critical metrics like response times, error rates, and service latency to identify areas for optimization.
Dependency Analysis: Maps relationships between services to understand system architecture and pinpoint problematic interactions.
Root Cause Analysis: Assists in diagnosing performance bottlenecks and pinpointing the sources of errors.
Adaptive Sampling: Dynamically adjusts data collection rates to balance observability with system overhead.
OpenTelemetry Support: Compatible with the
OpenTelemetry standard for flexible instrumentation across platforms.
