| Course | Tuition | |
|---|---|---|
| Signals that stay useful under load Shape metric collection so dashboards stay readable when traffic spikes, without drowning operators in noise. Intermediate · Prometheus, Grafana | KRW 420,000 | → |
| Dashboards operators actually open Move from pretty panels to navigation aids: hierarchy, defaults, and on-call ergonomics for metrics and dashboards work. Beginner-plus · Grafana, Loki touchpoints | KRW 310,000 | → |
| Log lines with intent, not volume Design structured fields and sampling policies so log analysis stays searchable when services get chatty. Intermediate · OpenSearch, Vector pipelines | KRW 280,000 | → |
| Tracing paths across async boundaries Propagate context through queues, batch jobs, and hand-written HTTP clients without turning every span into noise. Advanced · OpenTelemetry, Jaeger | KRW 540,000 | → |
| Incident rooms with calmer timelines Practice timelines, roles, and observability checkpoints so incident response feels coordinated instead of theatrical. Mixed · Any metrics stack | KRW 890,000 | → |
| SLOs teams can defend in planning Draft error budgets, user-journey slices, and measurement windows that survive roadmap arguments and seasonal traffic. Intermediate · Prometheus recording rules | KRW 360,000 | → |
| Notebook labs for metric forensics Use notebooks responsibly to explore spikes without turning ad-hoc queries into permanent dashboards by accident. Intermediate · Python, Prometheus HTTP API | KRW 240,000 | → |
| On-call handoffs that preserve context Write shift notes, quiet alerts, and tracing bookmarks so the next rotation inherits situational awareness, not anxiety. Beginner-plus · PagerDuty-style mock, Grafana | KRW 1,950,000 | → |
| Telemetry contracts in code review Turn observability expectations into reviewable artifacts: diffs, schemas, and CI hints that nudge teams before merge. Advanced · GitHub Actions, OTel | KRW 180,000 | → |
