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+.
npm install --save @opentelemetry/instrumentation-dataloader^2.0.0
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 has some configuration options
| Options | Type | Description |
|---|---|---|
requireParentSpan |
boolean |
Require a parent span in order to create dataloader spans, default when unset is false. |
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.
