OpenTelemetry Postgres Instrumentation for Node.js

This module provides automatic instrumentation for pg.

For automatic instrumentation see the @opentelemetry/node package.

Installation

npm install --save @opentelemetry/plugin-pg
npm install --save @opentelemetry/plugin-pg-pool

Usage

To load all of the default supported plugins, use the below approach. Each plugin is only loaded when the module that it patches is loaded; in other words, there is no computational overhead for listing plugins for unused modules.

const { NodeTracerProvider } = require('@opentelemetry/node');

const provider = new NodeTracerProvider(); // All default plugins will be used

If instead you would just want to load a specific plugin (pg in this case), specify it in the NodeTracer configuration.

const { NodeTracerProvider } = require('@opentelemetry/node');

const provider = new NodeTracerProvider({
  plugins: {
    pg: {
      enabled: true,
      // You may use a package name or absolute path to the module
      path: '@opentelemetry/plugin-pg',
    }
  }
});

If you are using any of the pg.Pool APIs, you will also need to include the pg-pool plugin.

const { NodeTracerProvider } = require('@opentelemetry/node');

const provider = new NodeTracerProvider({
  plugins: {
    pg: {
      enabled: true,
      // You may use a package name or absolute path to the module
      path: '@opentelemetry/plugin-pg',
    },
    'pg-pool': {
      enabled: true,
      // You may use a package name or absolute path to the module
      path: '@opentelemetry/plugin-pg-pool',
    },
  }
});

See examples/postgres for a short example.
