Jaeger traces requests through a distributed system, recording data about each request as it moves through different services. It offers a graphical representation, known as a trace graph or tree, to help developers understand request processing and identify bottlenecks or issues.
In addition to tracing, Jaeger collects metrics related to service performance, such as response times, error rates, and throughput. It seamlessly integrates with various programming languages and frameworks, enabling easy application instrumentation and supports popular languages like Node.js, Java, and Go.
Jaeger helps in debugging problems by identifying bottlenecks, slow components, and errors. It also aids in optimizing performance by pinpointing areas for improvement. Furthermore, it allows developers to understand the overall flow of their application, gaining insights into dependencies and behavior.
Using Jaeger can benefit application development by providing insights into performance optimization, problem debugging, and overall flow visualization similar to how a diligent waiter follows a customer in a restaurant. OpenTelemetry acts as a universal language for tracing tools, including Jaeger.
