I've heard a lot about how important monitoring is while studying backend development, but when I actually tried to implement Prometheus or Grafana myself, I didn't know where to start. This lecture was great because it organized those vague areas in a short and clean way. In particular, even though the course isn't long, it contains all the core essentials, so I was able to finish it without feeling overwhelmed. It really helped me understand the overall flow even as a beginner. I recommend this to anyone who is new to monitoring like I am. I look forward to the next lecture.
