“The capstone critique on our signup Signal Map was blunt in the best way. We cut four metrics and finally agreed on one signup SLI.”Sora N. · Product engineer · Seoul
Flagship course
Application Signal Analytics Studio
A guided atelier for engineers and adjacent roles who want application analytics that survive real cloud performance monitoring — not demo-day dashboards.
Learning outcomes
- Build a Signal Map for one production journey
- Explain latency histograms without flattening them into averages
- Rewrite alerts with soft thresholds and clear runbook verbs
- Present a three-minute performance story to a mixed audience
- Spot dashboards that flatter releases and correct them
Informational pricing
Individual enrollment via Metric Atelier is listed at ₩620,000. Team seats through Observatory Circle are arranged separately. There is no online checkout — contact us to reserve a cohort seat. See pricing and refunds.
Instructor · Yuna Kim
Former platform lead for a Korea-based marketplace, Yuna now teaches signal literacy full time from Daegu. She specializes in multi-region latency narratives and quiet alerting culture.
Modules
- Telemetry manners — naming, labels, and cardinality budgets that humans can love.
- SLIs customers would recognize — choosing signals that map to journeys, not boxes.
- Histograms without fear — buckets, heatmaps, and stakeholder-safe language.
- Trace corridors — following a request across regions without drowning in spans.
- Alert manners — soft thresholds, quiet hours, and escalation poetry.
- Dashboard honesty — removing vanity panels and writing chart captions.
- Incident storytelling — timelines that teach, not blame.
- Signal Map capstone — critique session with facilitator notes you can take to work.
Reviews from this studio
“Office hours were generous. The live debugging demos were shorter than I hoped — I leaned on the Trace Corridors readings to fill the gap.”Client in healthcare analytics
FAQ
Do I need a specific observability vendor?
No. Examples use open standards and generic screenshots. Bring whatever you already run.
Is this suitable for product managers?
Yes if you partner with an engineer for labs. Pure PM cohorts often prefer Latency Storytelling first.
What is a real limitation of this course?
We do not cover metrics storage cost optimization or vendor contract negotiation in depth. Teams with exploding cardinality bills will need a separate FinOps conversation — we can point you to resources, but it is outside the Studio’s scope.
How are live sessions scheduled?
Primary live studio is Tuesday evenings KST. Recordings post within 24 hours.
