# Emitter Stats

This golang package is used for monitoring [emitter.io](emitter.io) cluster. This provides a tight binary compression and a single histogram/counter abstraction in order to deal with various kinds of system monitoring. This package is compatible with GopherJS (snapshot-only) and hence can also be compiled to javascript. Documentation is available on [go doc](https://godoc.org/github.com/emitter-io/stats).

## Installation

```

go get -u github.com/emitter-io/stats

```

## Quick Start

The package itself provides a general-purpose monitoring capabilities, with tight encoding using our [binary codec](https://github.com/kelindar/binary). While it's primarily have been built for emitter, it can be used anywhere.

Typical usage consists of creating a metric container, measuring various metrics and sending snapshots over the wire.

```

rand.Seed(time.Now().UnixNano())

// Create a container

m := stats.New()

// Measure few metrics

m.Measure("my.metric.1", rand.Int31n(1000))

m.Measure("my.metric.2", rand.Int31n(1000))

// Create a snapshot which can be transferred over the wire

bytes := m.Snapshot()

// Restore a snapshot from binary

v, err := stats.Restore(bytes)

// Get the values back

percentiles := v[0].Quantile(50, 90, 95, 99)

average := v[0].Mean()

count := v[0].Count()

```
