@bonniernews/exp-metrics v2.0.1

exp-metrics

Simple wrapper of OpenTelemetry metrics with the same API as prom-client, to make the transition from prom-client easy, and also add functionality that OpenTelemetry lacks.

Types of metrics and API

• Counter
  • inc([labels,] [value])
• Gauge
  • set([labels,] value)
  • inc([labels,] [value])
  • dec([labels,] [value])
• Summary (histogram in OpenTelemetry terms)
  • observe([labels,] value)

Installing

npm install @bonniernews/exp-metrics

Usage

const expMetrics = require("@bonniernews/exp-metrics");

metrics = expMetrics({
  "service.name": "my-service-name",
  "service.namespace": "my-namespace",
  "service.instance.id": "my-instance-id",
});

const myCounter = metrics.counter({
  name: "my_counter",
  help: "My counter",
})

myCounter.inc(2);
myCounter.inc({ foo: "bar" }, 3);
