Program narrative
You will design SLOs that match customer journeys, wire exemplars, and practice triage drills with deliberately messy data. The emphasis is on readability for humans rotating through pager duty, not dashboard sprawl.
Included focus areas
- • SLO drafting workshops with error budget math
- • Trace exemplars tied to representative user flows
- • Log schema contracts that survive schema drift
- • Runbooks linked from alert annotations
- • Noise reduction tactics for high-cardinality metrics
- • Post-incident templates that feed back into dashboards
- • Sampling strategies that preserve critical paths
Outcomes you can show
- Ship three SLOs with budgets tracked weekly
- Cut alert volume on a lab service without hiding failures
- Produce a joint metrics-and-logs drill narrative
Mentor of record
Elias Park
Career coach turned observability mentor; still carries a pager-shaped scar.
Participant notes
The triage drill with conflicting signals mirrored our last outage. Still tightening log cardinality.
Straight answers
Labs ship with open telemetry collectors feeding a hosted stack; no vendor contracts required.
