Hello Seunghwan! This is Sini from JSCODE! :) First of all, I'm so glad to hear that you've grasped the flow of log management and monitoring through my lecture! 🥹 It turns out you'll be using Prometheus and Grafana in your actual work! To be honest, these tools can feel overwhelming at first because there's so much to configure, but since you've gotten a feel for them through the course, all that's left is to build your own know-how by creating dashboards in a real-world setting!! As you apply this to your work, please feel free to leave a question anytime if you get stuck! Congratulations on completing the course~~!!
