## What it is
A Go port of Coda Hale's Dropwizard Metrics library providing counters, gauges, histograms, meters, and timers for application instrumentation. The repository was archived on April 1, 2025 and is no longer maintained.

## Use cases
- instrument go application metrics
- track request latency histograms in go
- count events with a go counter library
- export go metrics to graphite or influxdb
- measure function execution time in go

## When to choose
- maintaining an existing codebase that already depends on go-metrics
- you need a simple, dependency-light metrics library with a familiar Dropwizard-style API

## When to avoid
- starting a new Go project - use OpenTelemetry Go SDK or the Prometheus Go client instead
- you need actively maintained exporters or long-term support

## Facets
- artifact type: library
- maturity: abandoned
- function: monitoring, benchmarking
- domain: monitoring, developer-tools, performance
- platform: go, cross-platform
- tags: metrics, instrumentation, dropwizard-metrics-port, archived
