OpenTelemetry instrumentation for cassandra-driver

This module provides automatic instrumentation for the injection of trace context to cassandra-driver, 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-cassandra-driver

Usage

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { CassandraDriverInstrumentation } = require('@opentelemetry/instrumentation-cassandra-driver');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

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

registerInstrumentations({
  instrumentations: [
    new CassandraDriverInstrumentation(),
    // other instrumentations
  ],
});

const cassandra = require('cassandra-driver');
const client = new cassandra.Client({ ... });
await client.execute('select * from foo');

Instrumentation options

Option	Type	Default	Description

responseHook	CassandraDriverResponseCustomAttributeFunction	undefined	Hook for adding custom attributes before response is handled
maxQueryLength	number	65536	If enhancedDatabaseReporting is enabled, limits the attached query strings to this length.
