Im trying to create a cloudwatch alarm for dynamodb read capacity units

This is my code, I have given threshold as “4”, but in the console the threshold value is “0.07” instead of 4

resource "aws_cloudwatch_metric_alarm" "consumed_read_units" {
  alarm_name                = "dynamodb_${var.dynamodb_table_name}_consumed_read_units"
  comparison_operator       = "GreaterThanOrEqualToThreshold"
  evaluation_periods        = "5"
  metric_name               = "ConsumedReadCapacityUnits"
  namespace                 = "AWS/DynamoDB"
  period                    = "60"
  statistic                 = "Average"
  dimensions =  {
    TableName = "${var.dynamodb_table_name}"
  }
  threshold                 = "4"
  alarm_description         = "This metric monitors DynamoDB ConsumedReadCapacityUnits for ${var.dynamodb_table_name}"
  insufficient_data_actions = []
}
