Overview

Package apm provides a programmatic API for interacting with the New Relic APM product.

Package apm provides a programmatic API for interacting with the New Relic APM product. It can be used for a variety of operations, including:

- Reading, updating, and deleting APM applications

- Creating, reading, and deleting APM deployment markers

- Reading APM key transactions

- Creating, reading, and deleting APM labels

Authentication

You will need a valid API key to communicate with the backend New Relic APIs that provide this functionality. Using a Personal API key is the preferred method but an Admin's API key will also work. See the API key documentation below for more information on how to locate these keys:

https://docs.newrelic.com/docs/apis/get-started/intro-apis/types-new-relic-api-keys

Labels

New Relic One entity tags are currently the preferred method for organizing your New Relic resources. Consider using entity tags via the `entities` package if you are just getting started. More information about entity tags and APM labels can be found at the following URL:

https://docs.newrelic.com/docs/new-relic-one/use-new-relic-one/core-concepts/tagging-use-tags-organize-group-what-you-monitor#labels

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

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

// Search the applications for the current account by name.
listParams := &ListApplicationsParams{
	Name: "Example application",
}

apps, err := client.ListApplications(listParams)
if err != nil {
	log.Fatal("error listing applications:", err)
}

// Get an application by ID.  This example assumes that at least one application
// has been returned by the list endpoint, but in practice it is possible
// that an empty slice is returned.
app, err := client.GetApplication(apps[0].ID)
if err != nil {
	log.Fatal("error getting application:", err)
}

// Update an application's settings.  The following example updates the
// application's Apdex threshold.
updateParams := UpdateApplicationParams{
	Name: app.Name,
	Settings: ApplicationSettings{
		AppApdexThreshold: 0.6,
	},
}

app, err = client.UpdateApplication(app.ID, updateParams)
if err != nil {
	log.Fatal("error updating application settings:", err)
}

// Delete an application that is no longer reporting data.
if !app.Reporting {
	_, err = client.DeleteApplication(app.ID)
	if err != nil {
		log.Fatal("error deleting application:", err)
	}
}

Output:
Example (KeyTransaction) 
// Initialize the client configuration.  A Personal API key or Admin API key
// is required to communicate with the backend API.
cfg := config.New()

// Initialize the client.

// Search the key transactions for the current account by name.
listParams := &ListKeyTransactionsParams{
	Name: "Example key transaction",
}

transactions, err := client.ListKeyTransactions(listParams)
if err != nil {
	log.Fatal("error listing key transactions:", err)
}

// Get a key transaction by ID.  This example assumes that at least one key
// transaction has been returned by the list endpoint, but in practice it is
// possible that an empty slice is returned.
transaction, err := client.GetKeyTransaction(transactions[0].ID)
if err != nil {
	log.Fatal("error getting key transaction:", err)
}

// Output the key transaction's health status.
fmt.Printf("Key transaction status: %s\n", transaction.HealthStatus)

}

// Output the concatenated label key and associated application IDs for each.
for _, l := range labels {

}

// Add a label to the application that describes its data center's location.
label := Label{
	Category: "Datacenter",
	Name:     "East",
	Links: LabelLinks{
		Applications: []int{app.ID},
	},

// Delete a label from all linked applications and servers.
