This module provides automatic instrumentation for the [`knex`](https://github.com/knex/knex) module, which may be loaded using the [`@opentelemetry/sdk-trace-node`](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/opentelemetry-sdk-trace-node) package and is included in the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle. This module allows the user to automatically collect trace data and export them to their backend of choice.
|
|
|
|
If total installation size is not constrained, it is recommended to use the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle with [@opentelemetry/sdk-node](`https://www.npmjs.com/package/@opentelemetry/sdk-node`) for the most seamless instrumentation experience.
|
|
|
|
Compatible with OpenTelemetry JS API and SDK `1.0+`.
|
|
|
|

const { KnexInstrumentation } = require('@opentelemetry/instrumentation-knex');
|
|
const { ConsoleSpanExporter, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');
|
|
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
|
|
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
|
|
|
|
const provider = new NodeTracerProvider({
|
|
spanProcessors: [
|
|
new SimpleSpanProcessor(new ConsoleSpanExporter()),
|
|
],
|
|
});
|
|
|
|
provider.register();
|
|
|
|
registerInstrumentations({
|
|
instrumentations: [
|
|
new KnexInstrumentation({
|
|
maxQueryLength: 100,
|
|
})
|
|
],
|
|
tracerProvider: provider,
|
|
});
|
|
```
