Why telemetry is critical for modern software development

Telemetry serves as the primary source of truth when developers delegate code writing to AI agents.

#2 about 4 min

Distinguishing between telemetry, monitoring, and observability

Telemetry provides raw data, monitoring answers known systems questions, and observability enables ad-hoc application investigations.

#3 about 7 min

Preventing sensitive data leaks in application telemetry

Capturing everything by default often leads to accidentally exposing passwords, email addresses, and personally identifiable information.

#4 about 3 min

Avoiding over-instrumentation and unnecessary tracing noise

Recording every microsecond function call or static asset request creates overwhelming system noise instead of actionable insights.

#5 about 3 min

Planning instrumentation around critical application failure scenarios

Anticipating late-night on-call emergencies guides the implementation of telemetry that effectively answers critical system questions.

#6 about 3 min

Choosing the correct telemetry signal for the job

Using logs for high-frequency application events obscures insights that simple metrics or distributed traces naturally provide.

#7 about 2 min

Key takeaways for building trustworthy application telemetry

Regularly reviewing raw production data reveals hidden data leaks and unnecessary noise before real incidents happen.

#8 about 4 min

Handling compliance, logging definitions, and AI agent output

Audience questions clarify GDPR compliance boundaries and identify dangerous default instrumentation patterns produced by AI code generators.
