gin-wavefront

Go Report Card Godoc GitHub GitHub tag (latest SemVer)

gin-wavefront is a Gin middleware to emit metrics to Wavefront.

Prerequisites

To use this Gin middleware, you'll need to have

Installation

Using go get

go get github.com/retgits/gin-wavefront

Usage

To start, you'll need to initialize the Wavefront emitter:

wfconfig := &ginwavefront.WavefrontConfig{
    Server:        "https://<INSTANCE>.wavefront.com",
    Token:         "my-api-key",
    BatchSize:     10000,
    MaxBufferSize: 50000,
    FlushInterval: 1,
    Source:        "my-app",
    MetricPrefix:  "my.awesome.app",
    PointTags:     make(map[string]string),
}
wfemitter, err := ginwavefront.WavefrontEmitter(wfconfig)
if err != nil {
    fmt.Println(err.Error())
}

Now you can use the wfemitter as a middleware function in Gin

r := gin.New()
r.Use(wfemitter)

A complete sample app can be found in the examples folder
