OpenTelemetry Memcached Instrumentation for Node.js

This module provides automatic instrumentation for the memcached@>=2.2.0 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 @opentelemetry/instrumentation-memcached

Supported Versions

• memcached versions >=2.2.0 <3

Usage

OpenTelemetry Memcached 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 memcached.

To load a specific instrumentation (memcached in this case), specify it in the registerInstrumentations' configuration

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

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

registerInstrumentations({
  instrumentations: [
    new MemcachedInstrumentation({
      enhancedDatabaseReporting: false,
    }),
  ],
});

Configuration Options

Option	Type	Example	Description
enhancedDatabaseReporting	boolean	false	Include full command statement in the span - leaks potentially sensitive information to your spans. Defaults to false.
