@opentelemetry/instrumentation-dataloader

OpenTelemetry instrumentation for dataloader

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

Supported Versions

• dataloader versions >=2.0.0 <3

Usage

const { NodeTracerProvider } = require("@opentelemetry/sdk-trace-node");
const {
  DataloaderInstrumentation,
} = require("@opentelemetry/instrumentation-dataloader");
const { registerInstrumentations } = require("@opentelemetry/instrumentation");

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

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

Dataloader Instrumentation Options

Dataloader instrumentation has some configuration options

Options	Type	Description
requireParentSpan	boolean	Require a parent span in order to create dataloader spans, default when unset is false.

Spans created

Each call to .load or .loadMany will create a child span for the current active span.

The batch load function of the dataloader also creates a span, which links to spans created as part of .load and .loadMany, it is a child span of whatever the active span is during which the dataloader is created.
