What recent observability practice or tool have you adopted, and what improved? [Advanced]
Answer
A recent observability practice I have adopted is using OpenTelemetry as a standard instrumentation and collection layer, combined with SLO-based alerting. It improved vendor flexibility, trace correlation, and reduced alert noise by focusing pages on user-impacting burn rates.
Technical explanation
OpenTelemetry standardizes service names, resource attributes, trace context, and export paths across languages.
A collector pipeline lets platform teams manage sampling, filtering, enrichment, and routing centrally.
SLO-based alerting moved the team away from CPU-style pages toward user-impacting conditions.
Hands-on example
Interview example: I would describe migrating one service first: enable OTel auto-instrumentation, route telemetry through a Collector, add trace_id to logs, build an SLO dashboard, and replace noisy pod alerts with error-budget burn alerts. The result is faster triage and fewer non-actionable pages.
