Kubernetes Exemplar Linking and Full-Stack Dashboard Creation
Exemplar linking takes the guesswork out of troubleshooting, associating metrics data points with exact traces. In this lab, you will enable and configure exemplar linking for the observability stack, then develop a Grafana dashboard for effectively tracking issues in the provided application. Finally, you will simulate an issue with high latency and leverage the new dashboard to troubleshoot the “issue.”

Challenge
Enable Prometheus exemplars
Update the Prometheus stack values file to enable exemplars, then add Prometheus as a data source in the Grafana UI with exemplars turned on and set to associate with the internal Tempo data source, looking for the
traceIdlabel. -
Challenge
Build a dashboard for the storefront application
Within the Grafana UI, create a dashboard for the storefront application, tracking request rate, latency, and request status by service. Additionally, include panels that show recent logs.

Challenge
Practice the troubleshooting workflow
Using the
high-latency-traffic.shscript, generate some troublesome traffic against the demo application. Then, leverage your newly-created dashboard to move through the troubleshooting workflow, from metrics to traces using exemplars.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
