@kurrent/opentelemetry

This module provides automatic tracing instrumentation for [KurrentDB-Client-NodeJS].

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @kurrent/opentelemetry

Supported Versions

• [1.x]

It's likely that the instrumentation would support earlier versions of KurrentDB, but this has not been tested.

Usage

OpenTelemetry KurrentDB Instrumentation allows the user to automatically collect trace data from append and subscription operations and export them to the backend of choice.

To load the instrumentation, specify it in the instrumentations list to registerInstrumentations. There is currently no configuration option.

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

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

registerInstrumentations({
  instrumentations: [
    new KurrentDBInstrumentation(),
  ],
});
