    {
      name = "10-common"
      override_action = "count"
      priority = 10
      statement = {
        name          = "AWSManagedRulesCommonRuleSet"
        vendor_name   = "AWS"
        version = "Version_1.2"
        excluded_rule = []
      }
      visibility_config = {
        cloudwatch_metrics_enabled = false
        sampled_requests_enabled   = false
        metric_name                = "10-common-metric"
      }
    }
]
