Log Management and Monitoring - ELK, Prometheus, Grafana

🥵 You still don't know how to log, so you're using System.out.print..?

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 those of you reading this might be in a similar situation as I was.
Whether during projects or at work, while self-consciously trying to debug,
are you still typing out System.out.print?

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.cũng như không muốn bị xem thường là một nhà phát triển thậm chí còn không biết về log.

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 tell you.

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 theory!
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 real-world practice..

Then, I'll see you in the lecture. ☺️

✔ Notes

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

However, please note that even if you lack some of these concepts, we have included
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 listening to the lecture, please feel free to ask via the
Question Board (Q&A Board) or the 1:1 Open KakaoTalk room!🤩

I will check it quickly and provide an answer.

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

A practitioner is someone who writes code well.

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

There are many experts 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 rather than on the weight of education.

Receiving the wrong education makes the learning process itself painful,
and 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 turn complex concepts into our own language instead of 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 that I was dragged by a friend to 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 a service myself,
wouldn't raising one truly skilled developer have a much greater impact on the world?'

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

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

Watching 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 generously share the skills and know-how I have accumulated in the field
to help you grow into a 'capable developer' who creates new value.

I sincerely hope that this lecture, prepared with great care,
brings a positive change to your life as a developer! 🙌
