Documentation

Overview

Package nrdb provides a programmatic API for interacting with the New Relic Database. It can be used to run freeform NRQL queries. Details on how to use the New Relic Query Language are available here:

https://docs.newrelic.com/docs/query-data/nrql-new-relic-query-language/getting-started/introduction-nrql

Authentication

You will need a valid Personal API key to communicate with the backend New Relic API that provides this functionality. See the API key documentation below for more information on how to locate this key:

Example (Query) 
// Initialize the client configuration.  A Personal API key is required to
// communicate with the backend API.
cfg := config.New()
cfg.PersonalAPIKey = os.Getenv("NEW_RELIC_API_KEY")

accountID, err := strconv.Atoi(os.Getenv("NEW_RELIC_ACCOUNT_ID"))
if err != nil {
	log.Fatal("example requires NEW_RELIC_ACCONT_ID to be set, got error: ", err)
}

// Initialize the client.
client := New(cfg)

// Execute a NRQL query to retrieve the average duration of transactions for
// the "Example application" app.
query := Nrql("SELECT average(duration) FROM Transaction TIMESERIES WHERE appName = 'Example application'")

resp, err := client.Query(accountID, query)
if err != nil {
	log.Fatal("error running NerdGraph query: ", err)
}

var durations []float64
for _, r := range resp.Results {
	durations = append(durations, r["average.duration"].(float64))
}

// Output the raw time series values for transaction duration.
fmt.Printf("durations: %v\n", durations)
