OpenTelemetry Restify Instrumentation for Node.js

NPM Published Version Apache License

This module provides automatic instrumentation for the restify module, which may be loaded using the @opentelemetry/sdk-trace-node package and is included in the @opentelemetry/auto-instrumentations-node bundle. It allows the user to automatically collect trace data and export them to their backend of choice.

If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-node bundle with @opentelemetry/sdk-node for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/instrumentation-restify

Supported Versions

Usage

const { RestifyInstrumentation } = require('@opentelemetry/instrumentation-restify');
const { ConsoleSpanExporter, SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();

provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.register();

registerInstrumentations({
  instrumentations: [
    new RestifyInstrumentation()
  ],
});

See examples/restify for a short example.

Restify Instrumentation Options

| Options | Type | Example | Description | | requestHook | RestifyCustomAttributeFunction | (span, requestInfo) => {} | Function for adding custom attributes to restify requests. Receives params: Span, RestifyRequestInfo. |

Using requestHook

Instrumentation configuration accepts a custom "hook" function which will be called for every instrumented restify request. Custom attributes can be set on the span or run any custom logic per request.

import { RestifyInstrumentation } from "@opentelemetry/instrumentation-restify"
const restifyInstrumentation = new RestifyInstrumentation({
  requestHook: function (span: Span, info: RestifyRequestInfo) {
    span.setAttribute(
      'http.method',
      info.request.method,
    )
  }
});
