This module provides automatic instrumentation for the [`fs`](http://nodejs.org/dist/latest/docs/api/fs.html) 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.
|
|
|
|
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+`.
|
|
|
|
See the full list of instrumented functions in [constants.ts](src/constants.ts);
|
|
|
|

## Supported Versions
|
|
|
|
- Node.js `>=14`
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
|
|
const { FsInstrumentation } = require('@opentelemetry/instrumentation-fs');
|
|
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
|
|
|
|
const provider = new NodeTracerProvider();
|
|
provider.register();
|
|
|
|
registerInstrumentations({
|
|
instrumentations: [
|
|
new FsInstrumentation({
|
|
// see below for available configuration
|
|
}),
|
|
],
|
|
});

|
You can set the following:
|
|
|
|
| Options | Type | Description |
|
|
| ------------------- | --------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- |
|
|
| `createHook` | `(functionName: FMember \| FPMember, info: { args: ArrayLike<unknown> }) => boolean` | Hook called before creating the span. If `false` is returned this and all the sibling calls will not be traced. |
|
|
| `endHook` | `( functionName: FMember \| FPMember, info: { args: ArrayLike<unknown>; span: api.Span } ) => void` | Function called just before the span is ended. Useful for adding attributes. |
|
|
| `requireParentSpan` | `boolean` | Require parent to create fs span, default when unset is `false`. |
