go-wavefront-management-api's Introduction

Golang Wavefront Client

Golang SDK for interacting with the Wavefront v2 REST API, and sending metrics through a Wavefront proxy.

Usage

API Client

Supports most public API paths. Refer to the documentation for further information.

package main

import (
    "fmt"
    "log"
    "os"

    wavefront "github.com/WavefrontHQ/go-wavefront-management-api"
)

func main() {
    client, err := wavefront.NewClient(
        &wavefront.Config{
            Address: os.Getenv("WAVEFRONT_ADDRESS"),
            Token:     os.Getenv("WAVEFRONT_TOKEN"),
        },
    )

    query := client.NewQuery(
        wavefront.NewQueryParams(`ts("cpu.load.1m.avg", dc=dc1)`),
    )

    result, err := query.Execute()

    if err != nil {
        log.Fatal(err)
    }

    if len(result.TimeSeries) > 0 {
        fmt.Println(result.TimeSeries[0].Label)
        fmt.Println(result.TimeSeries[0].DataPoints[0])
    } else {
        fmt.Println("No matching data.")
    }
}

Writer

Writer has full support for metric tagging etc.

Again, see examples for a more detailed explanation.

package main

import (
    "log"
    "os"

    wavefront "github.com/WavefrontHQ/go-wavefront-management-api/writer"
)

func main() {
    source, _ := os.Hostname()

    wf, err := wavefront.NewWriter("wavefront-proxy.example.com", 2878, source, nil)
    if err != nil {
        log.Fatal(err)
    }
    defer wf.Close()

    wf.Write(wavefront.NewMetric("something.very.good.count", 33))
}
