# StatsD

**Canonical:** https://apis.io/providers/statsd/  
**APIs profiled:** 8

StatsD is the network daemon and UDP-based line protocol for application metrics, originally written at Etsy and now maintained at github.com/statsd/statsd. A StatsD client emits short text packets — counters, gauges, timers, histograms, sets, and meters — to a daemon that aggregates them in memory and flushes derived series to a backend such as Graphite, InfluxDB, Datadog, CloudWatch, or any of 30+ third-party sinks. The wire format is the canonical contract; dozens of language clients and several alternative servers (DogStatsD, Telegraf, gostatsd, brubeck, statsite, Veneur, bioyino) speak it with small, well-documented dialect extensions for tags, histograms, events, and service checks.
