opentelemetry-node-metrics

This module is an adoption of the metric set of prom-client for @opentelemetry/metrics.

There's no node cluster support as @opentelemetry/metrics doesn't support it.

Usage

const {MeterProvider} = require('@opentelemetry/metrics');
const {PrometheusExporter} = require('@opentelemetry/exporter-prometheus');

const exporter = new PrometheusExporter({startServer: true}, () => {
  console.log(
    `prometheus scrape endpoint: http://localhost:${PrometheusExporter.DEFAULT_OPTIONS.port}${PrometheusExporter.DEFAULT_OPTIONS.endpoint}`,
  )
})

const meterProvider = new MeterProvider({
  exporter,
  interval: 2000,
})

require('./index')(meterProvider)

License

This project heavily relies on code from https://github.com/siimon/prom-client and therefore I'd like to thank to all the contributors.

The prom-client project is using an APACHE v2.0 LICENSE and threfore it's best to apply the same license to this project.

This module is only a proof of concept to get opentelemetry to work with the metrics support of prom-client.
