Always "no_data_timeframe = 0 -> 10" plan is displayed

[abicky]

Datadog recently seems to have changed the response of monitors with notify_no_data false and we always receive "no_data_timeframe = 0 -> 10" plan in spite of the fact we don't make any changes.

Terraform Version

Terraform v0.12.6

Affected Resource(s)

• resource_datadog_monitor

Terraform Configuration Files

variable "datadog_api_key" {}
variable "datadog_app_key" {}

provider "datadog" {
  api_key = "${var.datadog_api_key}"
  app_key = "${var.datadog_app_key}"
}

resource "datadog_monitor" "test" {
  name    = "test"
  type    = "metric alert"
  query   = "avg(last_5m):avg:aws.ec2.cpuutilization{*} > 10"
  message = "test"

  notify_no_data = false
}

Debug Output

Expected Behavior

We receive an output like below:

No changes. Infrastructure is up-to-date.

Actual Behavior

We receive an output like below:

Terraform will perform the following actions:

  # datadog_monitor.test will be updated in-place
  ~ resource "datadog_monitor" "test" {
        evaluation_delay    = 0
        id                  = "14793616"
        include_tags        = true
        locked              = false
        message             = "test"
        name                = "test"
        new_host_delay      = 300
      ~ no_data_timeframe   = 0 -> 10
        notify_audit        = false
        notify_no_data      = false
        query               = "avg(last_5m):avg:aws.ec2.cpuutilization{*} > 10"
        renotify_interval   = 0
        require_full_window = true
        silenced            = {}
        tags                = []
        threshold_windows   = {}
        thresholds          = {}
        timeout_h           = 0
        type                = "metric alert"
    }

Plan: 0 to add, 1 to change, 0 to destroy.

Steps to Reproduce

1. terraform apply
2. terraform plan
