TelemetryService class

Service for managing OpenTelemetry-based tracing and metrics.

Provides a unified interface for instrumenting ODBC operations with distributed tracing context.

Traces and spans are stored locally during operation and exported only when ended (to calculate accurate duration).

Implemented types

• ITelemetryService

Constructors

TelemetryService(ITelemetryRepository _repository)
