How can I use the Go Metrics library for basic metrics?

Can you explain how to use the Go Metrics library for basic metrics?

Sure! The Go Metrics library provides a simple way to collect and report metrics in Go applications. You can start by importing the library and initializing a metrics registry.

What types of metrics can I track with it?

You can track various metrics like counters, gauges, histograms, and timers. Each type serves a different purpose in monitoring your application.

Can you give me a code example for a counter?

Absolutely! Here's a simple example:

package main

import (
    "github.com/rcrowley/go-metrics"
    "time"
)

func main() {
    counter := metrics.NewCounter()
    metrics.Register("my_counter", counter)
    counter.Inc() // Increment the counter
    time.Sleep(1 * time.Second)
}

How do I visualize these metrics?

You can use tools like Grafana or Prometheus to visualize the metrics collected by the Go Metrics library. Just ensure you expose the metrics endpoint.
