Prometheus
==========
A Prometheus "pull" based implementation of the metrics Reporter interface.
Capabilities
------------
* Go runtime metrics are handled natively by the Prometheus client library (CPU / MEM / GC / GoRoutines etc).
* User-defined metrics are registered in the Prometheus client dynamically (they must be pre-registered, hence all of the faffing around in metric_family.go).
* The metrics are made available on a Prometheus-compatible HTTP endpoint, which can be scraped at any time. This means that the user can very easily access stats even running locally as a standalone binary.
* Requires a micro.Server parameter (from which it gathers the service name and version). These are included as tags with every metric.
Usage
-----
```golang
prometheusReporter := metrics.New(server)
tags := metrics.Tags{"greeter": "Janos"}
err := prometheusReporter.Count("hellos", 1, tags)
if err != nil {
fmt.Printf("Error setting a Count metric: %v", err)
}
```
