Supported Versions

This instrumentation supports >0.2.28:

Usage

For further automatic instrumentation instruction see the @opentelemetry/instrumentation package.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const { TypeormInstrumentation } = require('opentelemetry-instrumentation-typeorm');

const tracerProvider = new NodeTracerProvider({
  // be sure to disable old plugin
  plugins: {
    typeorm: { enabled: false, path: 'opentelemetry-plugin-typeorm' }
  }
});

registerInstrumentations({
  tracerProvider,
  instrumentations: [
    new TypeormInstrumentation({
      // see under for available configuration
    })
  ]
});

TypeORM Instrumentation Options

TypeORM instrumentation has few options available to choose from. You can set the following:

Options	Type	Description
responseHook	TypeormResponseCustomAttributesFunction	Hook called before response is returned, which allows to add custom attributes to span.
moduleVersionAttributeName	string	If passed, a span attribute will be added to all spans with key of the provided moduleVersionAttributeName and value of the patched module version
suppressInternalInstrumentation	boolean	Typeorm operation use mongodb/postgres/mysql/mariadb/etc. under the hood. If, for example, postgres instrumentation is enabled, a postgres operation will also create a postgres span describing the communication. Setting the suppressInternalInstrumentation config value to true will cause the instrumentation to suppress instrumentation of underlying operations.
enableInternalInstrumentation	boolean	Some methods such as getManyAndCount can generate internally multiple spans. To instrument those set this to true
collectParameters	boolean	set to true if you want to capture the parameter values for parameterized SQL queries (may leak sensitive information)
