How can I implement custom metrics in the Go Metrics library?

To implement custom metrics in the Go Metrics library, you can define your own metric types and register them.

What types of custom metrics can I create?

You can create counters, gauges, histograms, and timers as custom metrics.

Can you show me a code example for a custom counter?

Sure! Here's a simple example:

package main

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

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