Instrumentation
It includes SDK installation, event definitions, identifiers, properties, consent controls, error handling, and validation. Good instrumentation begins with business questions and a tracking plan, not with indiscriminate collection. Teams should test across platforms and versions, monitor data quality in production, and treat instrumentation changes like product code with review and ownership.
What is Instrumentation?
Instrumentation is the implementation of code, configuration, and processes that generate and send analytics data from a product or system.
Why it matters
It includes SDK installation, event definitions, identifiers, properties, consent controls, error handling, and validation. Good instrumentation begins with business questions and a tracking plan, not with indiscriminate collection. Teams should test across platforms and versions, monitor data quality in production, and treat instrumentation changes like product code with review and ownership.
Example
Engineers instrument an onboarding flow with events for each milestone, consistent user IDs, and properties for platform and experiment variant.
