Description

AWS deprecated property "Threshold" in AnomalySubscription of AWS Cost Anomaly Detector. They recommend using ThresholdExpression instead, but this is unsupported by Terraform provider.

• resource aws_ce_anomaly_subscription

Potential Terraform Configuration

resource "aws_ce_anomaly_subscription" "realtime_subscription" {
  name      = "RealtimeAnomalySubscription"
  threshold_expression = jsonencode({ "Or": [ { "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_ABSOLUTE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } }, { "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_PERCENTAGE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } } ] })
  frequency = "IMMEDIATE"

  monitor_arn_list = [
    aws_ce_anomaly_monitor.anomaly_monitor.arn,
  ]

  subscriber {
    type    = "SNS"
    address = aws_sns_topic.cost_anomaly_updates.arn
  }

  depends_on = [
    aws_sns_topic_policy.default,
  ]
}
