OpenTelemetry instrumentation for `tedious` database client for Microsoft SQL Server
npm install @opentelemetry/instrumentation-tedious[![NPM Published Version][npm-img]][npm-url]
[![Apache License][license-image]][license-image]
This module provides automatic instrumentation for the tedious 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-tedious
- tedious >=1.11.0 <20
OpenTelemetry Tedious Instrumentation allows the user to automatically collect trace data and export them to the backend of choice, to give observability to distributed systems when working with tedious.
To load a specific plugin, specify it in the registerInstrumentations's configuration:
`js
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { TediousInstrumentation } = require('@opentelemetry/instrumentation-tedious');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const provider = new NodeTracerProvider();
provider.register();
registerInstrumentations({
instrumentations: [
new TediousInstrumentation(),
],
})
`
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-tedious@0.28.0 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 to 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.
Attributes collected:
| Old semconv | Stable semconv | Description |
| --------------- | -------------------- | ---------------------------------- |
| db.system | db.system.name | 'mssql' (old), 'microsoft.sql_server' (stable) |db.statement
| | db.query.text | The database query being executed. |db.user
| | Removed | Username for accessing the database. |db.name
| | Removed | Integrated into new db.namespace. |db.namespace
| (not included) | | The database associated with the connection, qualified by the instance name. |db.sql.table
| | db.collection.name | The name of a collection (table, container) within the database. |net.peer.name
| | server.address | Remote hostname or similar. |net.peer.port
| | server.port | Remote port number. |
Database trace context propagation can be enabled by setting enableTraceContextPropagationto true`.
This uses the SET CONTEXT_INFO
command to set traceparentinformation
for the current connection, which results in an additional round-trip to the database.
