Java Framework For Trace Id Request

Learn how to implement centralized logging in a Spring Boot application to capture every request, response, and exception. Master the most popular Java testing framework. We'll also add an in-memory repository to store trace data. This allows us to temporarily store trace data without affecting the primary application logic

This document describes how to modify a Java app to collect trace and metric data using the open source OpenTelemetry framework, and how to write structured JSON logs to standard out. This document also provides information about a sample Java Spring Boot app that you can install and run. The app is configured to generate metrics, traces, and logs.

As most of us use spring boot as our got to framework for web development. And Also we are rapidly moving towards the Micro Services, One concern is to effectively monitor and trace the Application's Log. So In this distributed era we adapted to have Transaction IdTrace ID to trace the request propagation from start to end.

Step 2 Add trace id in log format. Logs in java do not add trace id by default, so to make this possible we can add the trace id we previously added in the thread context to the log. This can be added to the application.properties I have added XTRACE_ID in the default log console pattern.

In the UserClient class, we set the quotCorrelation-IDquot header in the outgoing HTTP request using the value retrieved from the MDC. This ensures that the downstream service receives the correlation ID and can also incorporate it into its logs and traces. Centralized Logging and Tracing with Correlation IDs

A Trace ID generator that produces a unique ID per request. A filter will be used to inject the Trace ID into each request. A Custom logger utility to include class, method, and line details.

Each span and trace gets a unique id. The first span of a trace often re-uses the trace ID as the span ID. Each service is expected to pass the trace ID to the next service it calls so that the next service can use the same trace ID as a correlation ID in its logs. This propagation of the trace ID is usually done via an HTTP header. In addition

Spring Boot projects come with a built-in logging framework and use Logback as the default logging implementation. If your Java project is a Spring Boot project, you can write TraceId into logs with minimal configuration. Set logging.pattern.level in application.properties, adding mdctrace_id and mdcspan_id to the logs.

For example, a trace can be a GET request that is querying data from our application. When our application processes the request, it can be split up into smaller steps user authorization, executing the database query, transforming the response. Each of these steps is a unique span belonging to the same trace.

Spring Boot, a popular framework for building Java applications, offers robust logging capabilities that can be further enriched by incorporating unique identifiers for each incoming request. So all the logs generated for a particular request will have a unique ID. With the help of this ID, we can easily trace through the logs. We can
