Usage

1. Use counters, gauges and histograms to collect metrics in your application.

   export class MyService {
   
       @metric()
       importantEvents = new CounterMetric('my_service_important_events_total', 'Total number of times something important happened.');
   
       doSomething() {
           // ...
           importantEvents.incr();
       }
   
   }
