wrong default value for datadog_monitor.no_data_timeframe

[arbll]

Terraform Version

Terraform v0.11.13

Affected Resource(s)

• datadog_monitor

Terraform Configuration Files

resource "datadog_monitor" "agent_running" {
  name = "${local.prefix} Agent is not running"
  type = "metric alert"
  query = "min(last_1m):min:datadog.agent.running{${local.filters}} by {host} < 1"

  message = <<EOT
${var.alert_handles}
EOT
  notify_no_data = true
}

Expected Behavior

According to the docs the default value for datadog_monitor.no_data_timeframe should be

Default: 2x timeframe for metric alerts, 2 minutes for service checks.

To be honest this default seems randomly chosen and I am not sure if it makes a lot of sense.

Actual Behavior

datadog_monitor.no_data_timeframe is set to 0 by default. This bring the strange side effect that editing a monitor created from terraform with datadog_monitor.no_data_timeframe equal to 0 in the web app will make the UI reset the value to the web app default (10 minutes).
