OpenTelemetry instrumentation for `mongoose` database object data modeling (ODM) library for MongoDB
npm install @opentelemetry/instrumentation-mongoose[![NPM Published Version][npm-img]][npm-url]
[![Apache License][license-image]][license-image]
This module provides automatic instrumentation for the mongoose module, 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 https://www.npmjs.com/package/@opentelemetry/sdk-node" class="text-primary hover:underline" target="_blank" rel="noopener noreferrer">@opentelemetry/sdk-node for the most seamless instrumentation experience.
Compatible with OpenTelemetry JS API and SDK 1.0+.
``bash`
npm install --save @opentelemetry/instrumentation-mongoose
- mongoose versions >=5.9.7 <9
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(),
],
})
`
This instrumentation implements Semantic Conventions (semconv) v1.7.0. Since then, networking (in semconv v1.23.1) and database (in semconv v1.33.0) semantic conventions were stabilized. As of @opentelemetry/instrumentation-mongoose@0.44.0 support has been added for migrating to the stable semantic conventions using the OTEL_SEMCONV_STABILITY_OPT_IN environment variable as follows:
1. Upgrade to the latest version of this instrumentation package.
2. Set OTEL_SEMCONV_STABILITY_OPT_IN=http/dup,database/dup to emit both old and stable semantic conventions. (The http token is used to control the net. attributes, the database token to control the db. attributes.)OTEL_SEMCONV_STABILITY_OPT_IN=http,database
3. Modify alerts, dashboards, metrics, and other processes in your Observability system to use the stable semantic conventions.
4. Set to emit only the stable semantic conventions.
By default, if OTEL_SEMCONV_STABILITY_OPT_IN includes neither of the above tokens, the old v1.7.0 semconv is used.
The intent is to provide an approximate 6 month time window for users of this instrumentation to migrate to the new database and networking semconv, after which a new minor version will use the new semconv by default and drop support for the old semconv.
See the HTTP migration guide and the database migration guide for details.
