Log Management and Monitoring - ELK, Prometheus, Grafana

🥵 Are you still printing logs with System.out.print because you don't know how to do it properly..?

I am JSCODE Sini, who started as a developer and has produced over 200 developers while working as a bootcamp instructor for 5 years.

Looking back at my time as a junior developer, I think I studied tech stacks like Spring really hard,
but I never once studied log management.

I suspect many of you reading this might be in a similar situation as I was.
Whether it's for a project or at work, are you still self-consciously typing
System.out.print just to debug?

I fully understand that you've made up your mind that you should study log management someday,
but you don't know where or how to start,
and you don't want to be looked down upon as a developer who doesn't even know about logs.

I also remember pretending to know what I was talking about because I didn't want to be looked down upon.🥺

Perhaps this concept is so obvious that no one ever bothered to explain it.

I created this course so that those new to log management and monitoring can learn quickly in a short period and
apply it directly to their practical work.

Practice is better than a hundred words!
Rather than studying concepts for a hundred days,
it is fastest to implement it yourself with code and apply it to a real-world project.

👍 Recommended for these people!

🎯 The goal of this course is clear.

Beginners in log management and monitoring will learn
how to write logs suitable for practical work in just 3 hours, and
will be able to monitor systems using the ELK stack (Elasticsearch, Logstash, Kibana),
Prometheus, and Grafana.

I hope you don't have to pretend to know things while walking on eggshells, like I did during my junior years.
Do you want to study logging properly?
Have you suddenly been assigned the task of managing and visualizing logs using the ELK stack?

If so, I hope you take this course to lower your fears
and firmly grasp only the core concepts essential for practical application.

I'll see you in the lecture. ☺️

✔ Notes

This course is conducted under the assumption that you have a basic understanding of Java fundamentals, Spring Boot, and Docker.

However, please note that even if you lack some of these concepts, the course includes
additional explanations and code comments to ensure you have no trouble with the hands-on practice.

💬 What if you have questions while listening to the lecture?

If you have any questions or find something difficult to understand while taking the lecture, please use the
Question Board (Q&A Board) or the 1:1 Open KakaoTalk room to ask!🤩

I will check it quickly and provide an answer.

👩‍💻 There are many practitioners who write good code, but few educators who can make that code easy to understand.

A practitioner is someone who writes good code.

However, an educator is someone who ponders day and night about why the code was written that way and
how to deliver the code to students in the easiest way possible.

There are many masters in the field, but
often their explanations are so difficult that they leave you tilting your head in confusion.
This is because they focused more on listing knowledge than on the weight of education.

If you receive the wrong education, the learning process itself becomes painful,
and it ultimately leads to unwanted results, wasting precious time and opportunities in your life.

I want to be more than just an 'instructor' who simply passes on skills; I want to be a
'teacher' who contemplates your career and life together with you.

The power to translate complex concepts into our own language rather than technical jargon—
that is my pride as an educator.

Please take a look at the path I have walked and my sincerity,
and make a careful decision for your precious future.

💚 Introducing myself!

Hello! I am JSCODE Sini.
It feels like just yesterday when I was dragged by a friend to attend a major class in college,
but I've already been developing for nearly 10 years.

At first, I wanted to make a positive impact on the world through the programs I created.
However, as time passed, I came to one firm realization.

'Rather than creating services myself,
wouldn't properly raising one talented developer have a much greater impact on the world?'

If the developers I've taught create wonderful services in their respective positions,
that positive influence will grow exponentially.

With that single mindset, I have trained over 200 developers at bootcamps over the past 5 years.
(* Produced successful candidates for Line, Kakao, and Kurly ☺️)

Seeing my students grow as they enter the industry,
I feel the power and fulfillment of education every single day.

Now, I intend to meet you beyond the offline classroom, in the wider online world.

I want to help you grow into a 'skilled developer' who creates new value by unreservedly sharing the techniques and know-how I have accumulated in the field.

I sincerely hope that this lecture, prepared with great care,
brings a pleasant change to your development career! 🙌
