To use the plugin, you need to download and install it, and then register it with your tracer.

See Lightstep’s GitHub for a full example.

Download and Install the Plugin

The npm packages are available from npm.

From a shell, run the following:

$ npm_config_registry=https://npm.pkg.github.com/lightstep npm install @lightstep/opentelemetry-plugin-rollbar --save

Initialize the Plugin

In your OpenTelemetry initialization code, use registerInstrumentation() to load plugins. See the Demo app for a full example.

const {
  lightstep, opentelemetry,
} = require('lightstep-opentelemetry-launcher-node');

module.exports = async (serviceName) => {
  const sdk = lightstep.configureOpenTelemetry({
    accessToken: process.env.LS_ACCESS_TOKEN,
    serviceName,
    instrumentations: [
    {
      plugins: {
      'rollbar': {
        path: 'opentelemetry-plugin-rollbar',
        enabled: true,
        },  
      },
    },
    ],
  }),
};

In the next step, you’ll see the trace data generated by the new instrumentation.

What Did We Learn?

  • Lightstep’s OpenTelemetry plugins automatically instrument your code to send and display Rollbar data in Lightstep.
