grafanadata

Query the Grafana API based off dashboards and panels and return the data in either prometheus or grafana format

Install

go get github.com/weka/grafanadata/go/pkg/grafanadata

Example usage

package main

import (
	"log"
	"time"

	"github.com/weka/grafanadata/go/pkg/grafanadata"
)

func main() {

	u := "http://localhost:3000/"
	t := "glsa_5N21WQvXza0oWkbqQvjOhII8yJYxGS0G_fbb82943"
	uid := "bebca380-068d-463d-9c9c-1bb19cb8d2b3"
	panelID := 7


	client, err := grafanadata.NewGrafanaClient(u, t)

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

	start := time.Now().Add(time.Hour * 24 * -2)
	data, err := client.GetPanelDataFromID(uid, panelID, start)

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

	log.Default().Println(data)
}

Convert response to a Prometheus Format

func main() {

	...

	uid := "bebca380-068d-463d-9c9c-1bb19cb8d2b3"
	panelID := 7

	// Get last 24 hours
	data, err := client.GetPanelDataFromID(uid, panelID, time.Now().Add(time.Hour*24*-1))
	if err != nil {
		return err
	}
	prometheusData := grafanadata.ConvertResultToPrometheusFormat(data)
	log.Println(prometheusData)

}

Iterate through an entire dashboard

func main() {
	...

	uid := "bebca380-068d-463d-9c9c-1bb19cb8d2b3"

	resp, err := client.GetDashboard(uid)
	if err != nil {
		return
	}

	start := time.Now().Add(time.Hour * 24 * -2)
	for _, panel := range resp.Dashboard.Panels {
		data, _ := client.GetPanelDataFromID(uid, panel.ID, start)
		log.Println(data)
	}
}
