OpenTelemetry Knex Instrumentation for Node.js

NPM Published Version Apache License

This module provides automatic instrumentation for the knex module, which may be loaded using the @opentelemetry/sdk-trace-node package and is included in the @opentelemetry/auto-instrumentations-node bundle. This module allows the user to automatically collect trace data and export them to their backend of choice.

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.

Compatible with OpenTelemetry JS API and SDK 1.0+.
