## Summary

Software engineers frequently rely on separate product analytics tools and teams to answer user behavior questions, creating disjointed data models and delayed insights. Existing debugging telemetry within tools like Sentry—specifically spans, structured logs, and application metrics—can serve as the primary source for product metrics. Developers enrich request spans with business-level attributes, record discrete business events through wide structured logs, and track KPIs with metric counters and distributions. This unified telemetry links business outcomes directly to underlying traces, errors, releases, and source code lines, enabling immediate root-cause analysis and automated alerts. While multi-session cohort and funnel aggregation remains a current tooling gap, standard telemetry solves day-to-day adoption, performance, and revenue questions.

## Context

Product analytics and engineering telemetry are conventionally separated, causing delays where analytics dashboards detect adoption drops weeks later without explaining root technical causes.

## Approach / What changed

Developers repurpose spans, structured logs, and application metrics by attaching business-level attributes such as user tiers and revenue deltas directly to existing application telemetry in Sentry.

## Takeaways

- Telemetry spans with custom business attributes enable simultaneous querying of feature adoption, runtime performance, and error rates in a single interface.
- Structured logs capture discrete revenue and business events while remaining correlated to underlying traces, errors, and specific commit releases.
- Complex cross-session funnels and 30-day cohort retention analysis remain difficult to reconstruct purely from request-scoped spans and event logs without specialized aggregation layers.
