Jaeger is an open-source tool designed for distributed tracing in microservices architectures. Its purpose is to monitor and diagnose the behavior of complex systems where multiple services interact, allowing the tracking of request flows across these services to identify performance issues, errors, or bottlenecks.
What does Jaeger do in microservices?
Request Tracing: Jaeger tracks the journey of a request as it passes through different microservices, showing how much time it takes in each and how it propagates through the system.
Latency Visualization: Provides a visual representation of request latency, helping to identify where delays occur.
Dependency Analysis: Displays relationships and dependencies between services, making it easier to understand the system’s architecture.
Error Diagnosis: Helps locate failures by showing where in the chain of microservices an issue occurs.
Distributed Monitoring: In microservices environments, where traditional logs are insufficient, Jaeger offers a unified view of request behavior.
