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

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.

[sudheerkumar-tpmg]

Mam I am big fan and follower of your channel and helped me to crack interviews. Thanks a lot

[vinaykumarmadiwalar]

Thank you for sharing this info, pls create the video for integrating with log4J2 and splunk in spring boot application

[rohanyelpale]

Mam your way of teaching is as beautiful as u :) thank you for such wonderful explanation

[ratankhandekar]

How to integrates log on slunk or winscp putty please do video on that. This video is very helpful

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

[ВиталийОвчаренко-ин]

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.

Much needed video thanks for covering this

[muhassinmusthafa]

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?

[rohanyelpale]

Mam please create video on which logging framework is recommended to use in spring boot and how log files will get generated once file is full or for new date new log file will get generated with some specific name format of log file.

[ganeshniranjan]

Very Big thank you for making such excellent videos.

[anuhyabolla]

Thanks for your videos
Continue with splunk and how the trace ids are generated logs and all

[deeptyrajput]

Thank you for the video, please create the video for integrating with log4J2 logs aggregation and monitoring using ELK Stack

[iamthefuelte]

congratulation for this video!! thanks!

[aditisingh]

It would be really helpful if you could please make video on integration with splunk.

[sudheerkumar-tpmg]

REGARDING SSO KEY CLOCK, can you make small video on what changes to perform to migrate already existing 2 web applications because the have their own logins and table what changes we need to perform at users table level to support key clock users also explain user federation with database

[senthilmurugangsm]

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

[sagarkorde-ci]

Hello mam, .... how to connect 2 api's or how to establish a connection between 2 Do u have a video to answer this question.

[anishsadanandhan]

Please make video on logback.xml usage.

[sangeethasaravanane]

well explained. Thank you for the effort.
