Google Cloud (Stackdriver) Monitoring Notification Channel

This page shows how to write Terraform for Cloud (Stackdriver) Monitoring Notification Channel and write them securely.

google_monitoring_notification_channel (Terraform)

The Notification Channel in Cloud (Stackdriver) Monitoring can be configured in Terraform with the resource name google_monitoring_notification_channel. The following sections describe 3 examples of how to use the resource and its parameters.

Example Usage from GitHub

resource "google_monitoring_notification_channel" "email" {
  count        = var.notification_group_email != "" ? 1 : 0
  project      = var.project
  display_name = var.notification_name
  type         = "email"
  labels = {
resource "google_monitoring_notification_channel" "email" {
  count        = local.is_email ? 1 : 0
  display_name = var.display_name
  type         = var.notification_type
  labels = {
    email_address = var.email_address
resource "google_monitoring_notification_channel" "slack" {
  display_name = "Test Slack Channel"
  type         = "slack"
  labels = {
    "channel_name" = "#tf-gitops-channel"


  • description optional - string
    • An optional human-readable description of this notification channel. This description may provide additional details, beyond the display name, for the channel. This may not exceed 1024 Unicode characters.

  • display_name optional - string
    • An optional human-readable name for this notification channel. It is recommended that you specify a non-empty and unique name in order to make it easier to identify the channels in your project, though this is not enforced. The display name is limited to 512 Unicode characters.

  • enabled optional - bool
    • Whether notifications are forwarded to the described channel. This makes it possible to disable delivery of notifications to a particular channel without removing the channel from all alerting policies that reference the channel. This is a more convenient approach when the change is temporary and you want to receive notifications from the same set of alerting policies on the channel at some point in the future.

  • id optionalcomputed - string
  • labels optional - map / string
    • Configuration fields that define the channel and its behavior. The permissible and required labels are specified in the NotificationChannelDescriptor corresponding to the type field. Labels with sensitive data are obfuscated by the API and therefore Terraform cannot determine if there are upstream changes to these fields. They can also be configured via the sensitive_labels block, but cannot be configured in both places.

  • name requiredcomputed - string
    • The full REST resource name for this channel. The syntax is: projects/[PROJECT_ID]/notificationChannels/[CHANNEL_ID] The [CHANNEL_ID] is automatically assigned by the server on creation.

  • project optionalcomputed - string
  • type required - string
  • user_labels optional - map / string
    • User-supplied key/value data that does not need to conform to the corresponding NotificationChannelDescriptor's schema, unlike the labels field. This field is intended to be used for organizing and identifying the NotificationChannel objects.The field can contain up to 64 entries. Each key and value is limited to 63 Unicode characters or 128 bytes, whichever is smaller. Labels and values can contain only lowercase letters, numerals, underscores, and dashes. Keys must begin with a letter.

  • verification_status requiredcomputed - string
    • Indicates whether this channel has been verified or not. On a ListNotificationChannels or GetNotificationChannel operation, this field is expected to be populated.If the value is UNVERIFIED, then it indicates that the channel is non-functioning (it both requires verification and lacks verification); otherwise, it is assumed that the channel works.If the channel is neither VERIFIED nor UNVERIFIED, it implies that the channel is of a type that does not require verification or that this specific channel has been exempted from verification because it was created prior to verification being required for channels of this type.This field cannot be modified using a standard UpdateNotificationChannel operation. To change the value of this field, you must call VerifyNotificationChannel.

Explanation in Terraform Registry

A NotificationChannel is a medium through which an alert is delivered when a policy violation is detected. Examples of channels include email, SMS, and third-party messaging applications. Fields containing sensitive information like authentication tokens or contact info are only partially populated on retrieval. Notification Channels are designed to be flexible and are made up of a supported type and labels to configure that channel. Each type has specific labels that need to be present for that channel to be correctly configured. The labels that are required to be present for one channel type are often different than those required for another. Due to these loose constraints it's often best to set up a channel through the UI and import to Terraform when setting up a brand new channel type to determine which labels are required. A list of supported channels per project the list endpoint can be accessed programmatically or through the api explorer at . This provides the channel type and all of the required labels that must be passed. To get more information about NotificationChannel, see:
