OpenTelemetry mysql Instrumentation for Node.js

This module provides automatic instrumentation for the mysql2 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.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @brokerize/opentelemetry-instrumentation-mysql2

Supported Versions

• mysql2 versions >=1.4.2 <4

Usage

OpenTelemetry MySQL2 Instrumentation allows the user to automatically collect trace data and export them to the backend of choice, to give observability to distributed systems when working with mysql2.

To load a specific plugin (MySQL2 in this case), specify it in the registerInstrumentations's configuration

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { MySQL2Instrumentation } = require('@opentelemetry/instrumentation-mysql2');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [
    new MySQL2Instrumentation(),
  ],
})
