Prometheus Metrics for Opossum Circuit Breaker

This module provides Prometheus metrics for opossum circuit breakers. To use it with your circuit breakers, just pass them in to the PrometheusMetrics constructor.

Example:

  const circuitBreaker = require('opossum');
  const PrometheusMetrics = require('opossum-prometheus');

  // create a couple of circuit breakers
  const c1 = circuitBreaker(someFunction);
  const c2 = circuitBreaker(someOtherfunction);

  // Provide them to the constructor
  const prometheus = new PrometheusMetrics([c1, c2]);

  // Write metrics to the console
  console.log(prometheus.metrics);

This module would typically be used in an application that can provide an endpoint for the Prometheus server to monitor.
