@opentelemetry/instrumentation-dns

OpenTelemetry DNS Instrumentation for Node.js

This module provides automatic instrumentation for the dns module, which may be loaded using the @opentelemetry/sdk-trace-node package and is included in the @opentelemetry/auto-instrumentations-node bundle.

If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-node bundle with @opentelemetry/sdk-node for the most seamless instrumentation experience.
