This module provides automatic instrumentation for the [`mongoose`](https://github.com/Automattic/mongoose) 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+`.
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
npm install --save @opentelemetry/instrumentation-mongoose
|
|
```
|
|
|
|
## Supported Versions
|
|
|
|
- `>=5.9.7 <7`
|
|
|
|
## Usage
|
|
|
|
To load a specific plugin, specify it in the registerInstrumentations's configuration:
|
|
|
|
```js
|
|
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
|
|
const { MongooseInstrumentation } = require('@opentelemetry/instrumentation-mongoose');
|
|
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
|
|
|
|
const provider = new NodeTracerProvider();
|
|
provider.register();
|
|
|
|
registerInstrumentations({
|
|
instrumentations: [
|
|
new MongooseInstrumentation(),
|
|
],
|
|
})
|
|
```
|
|
|
|
## Migration From opentelemetry-instrumentation-mongoose
|
|
|
|
This instrumentation was originally published and maintained under the name `"opentelemetry-instrumentation-mongoose"` in [this repo](https://github.com/aspecto-io/opentelemetry-ext-js).
|
|
|
|
Few breaking changes were made during porting to the contrib repo to align with conventions:
|
|
|
|
### Hook Info
|
|
|
|
The instrumentation's config `responseHook` functions signature changed, so the second function parameter is info object, containing the relevant hook data.
|
|
|
|
### `moduleVersionAttributeName` config option
|
|
|
|
The `moduleVersionAttributeName` config option is removed. To add the mongoose package version to spans, use the `moduleVersion` attribute in hook info for `responseHook` function.
|
|
|
|
