What is Logging in Spring boot
Logging in Spring Boot refers to the practice of recording information, events, and actions within a Spring Boot application.
It plays a crucial role in understanding the behavior of the application, diagnosing issues, and monitoring its performance.
Spring Boot offers flexible logging capabilities by integrating with various logging frameworks and providing standardized ways to configure and manage logs.
How logging is done is Spring boot
Java offers several logging frameworks, including log4J, java.util.logging (JUL), tiny log, logback, and more, to simplify the logging process for developers.
A logging framework handles various tasks, such as defining where log files are stored and customizing log messages.
Spring Boot includes SLF4J by default. SLF4J, which stands for Simple Logging Facade for Java, serves as a unified interface for these logging frameworks. With just one dependency, users can seamlessly utilize any of these logging frameworks.
What are the different level of Logging
Logging frameworks provide different levels to categorize log messages based on their severity and importance. Common logging levels include:
INFO: Informational messages that signify the application's operational activities. These messages give a high-level overview of the application's state and major events, useful for keeping track of normal functioning.
WARN: Warnings indicate potential issues that could cause problems in the future or highlight situations that might need attention. They are not critical errors but are worth investigating to prevent possible errors.
ERROR: Messages at this level represent actual errors that have occurred in the application. These could include exceptions, failed operations, or other issues that require attention to ensure proper functionality.

Remember the entire logging fiasco during a vulnerability leak in apache libraries. Had to sit the whole night on a weekend to change whole code bases. This video is so helpful. Thanks a lot team.

Mam I am big fan and follower of your channel and helped me to crack interviews. Thanks a lot
Superb explanation. If possible make a separate video on Spring MVC architecture and imp questions. i have watched many videos in this channel but can't find it
Thank you for the video, please create the video for integrating with log4J2 logs aggregation and monitoring using ELK Stack
Thanks for the video. Anyway it would be greatly helpful if the logging framework with latest spring boot version 3.x. Most of the problems with migration from boot 2.x to 3.x
Thank you for sharing this info, pls create the video for integrating with log4J2 and splunk in spring boot application

In this text, it seems like you have mentioned a few different topics related to software development, particularly in the context of Spring Boot and logging. Let me break down each topic for better understanding: 1. "Logging in Spring Boot with example": This refers to the process of configuring and utilizing logging mechanisms in a Spring Boot application. Spring Boot provides easy-to-use logging capabilities out-of-the-box, and you can customize it by using popular logging frameworks like Logback, Log4j, or Java Util logging. 2. "Logging Interview questions and Answers": This could be a set of questions that might be asked during an interview related to logging concepts, tools, or frameworks. Some common interview questions for logging could be about the importance of logging, different logging frameworks, log levels, and how to configure and optimize logging in an application. 3. "Code Decode deciding problems stages": This seems to be a combination of unrelated words. However, if we break it down, "Code Decode" might refer to the process of understanding or translating code written in a particular language or framework. "Deciding problems" could mean resolving issues or making decisions based on problem-solving techniques. "Stages" could refer to the various phases or steps involved in the problem-solving process. If you have any specific questions or need further clarification on any of these topics, please feel free to ask.

Hi Code Decode, Thanks for another simple tutorial..😍 Can you pls create a tutorial for log framework like log4j, lo4j2, lombok,logback and how to integrate with splunk Query here : Does this store the content in the same file when more logs are creating day by day and file size increase create any issues?
@CodeDecode
11 ай бұрын
Agreed that file size does increase day buy day bcz it's appending. But since it's text file, it's ok to have it for few days. After that you can achieve it
