Detect error condition during plan: Term duration must be a multiple of the aggregation window

[xero-grant-young]

Feature Description

In newrelic_nrql_alert_condition the terms[] (Critical/Warning) threshold_duration must be a multiple of the aggregation_window. This could be detected during the plan stage. Presently only alerts during apply.

This resource block

resource "newrelic_nrql_alert_condition" "my_critical_alert" {

  policy_id = newrelic_alert_policy.my_alert_policy.id

  name        = "My Critical Alert"
  type        = "static"
  expiration_duration = 900
  aggregation_window = 120
  aggregation_method = "event_flow"
  aggregation_delay = 120

  critical {
    threshold_duration = 300
    operator = "below"
    threshold = 99.9
    threshold_occurrences = "all"
  }

  nrql {
    query = <<-EOF
        SELECT ...
    EOF
  }
}

Would result in error

Error: Validation Error: BAD_USER_INPUT

Describe Alternatives

Detect if terms[].threshold_duration is not a multiple of aggregation_window during terraform plan phase.

Hi @xero-grant-young, thanks or raising the issue. We will prioritise it.

Hi @xero-grant-young this is a deliberate choice. The validation was changing too quickly in the Alerts API for the Terraform Provider to keep up so we're just handling validation through the API.
