How to iterate over map of objects?

Hi all. I wanted to ask you for some help.
I have a variable that looks like this:

variable "pol" {
  default = {
    "TOPIX" : {
      "Top-prod CPUUtilization" : {
        "query" : "SELECT average(`aws.rds.CPUUtilization`) FROM Metric WHERE aws.rds.DBInstanceIdentifier LIKE '%top-prod%'",
        "critical_threshold" : 10,
        "warning_threshold" : 5,
        "operator" : "above"
      },
      "Top-prod ELB-4xx" : {
        "query" : "SELECT sum(`aws.applicationelb.HTTPCode_ELB_4XX_Count`) FROM Metric WHERE aws.applicationelb.dnsName LIKE '%top-prod%'",
        "critical_threshold" : 10,
        "warning_threshold" : 5,
        "operator" : "above"
      }
    },
    "TOP2" : {
      "Top2-prod CPUUtilization" : {
        "query" : "SELECT average(`aws.rds.CPUUtilization`) FROM Metric WHERE aws.rds.DBInstanceIdentifier LIKE '%top-prod%'",
        "critical_threshold" : 10,
        "warning_threshold" : 5,
        "operator" : "above"
      },
      "Top2-prod ELB-4xx" : {
        "query" : "SELECT sum(`aws.applicationelb.HTTPCode_ELB_4XX_Count`) FROM Metric WHERE aws.applicationelb.dnsName LIKE '%top-prod%'",
        "critical_threshold" : 10,
        "warning_threshold" : 5,
        "operator" : "above"
      }
    },
  }
}

And I have a resource that should take those values.

  policy_name = ""
  alert_name  = ""
  critical_threshold = 0
  operator = ""
  query = ""
  warning_threshold = 0

I want to create next resources:

---
policy_name = TOP
alert_name = "Top-prod CPUUtilization"
critical_threshold = 10
warning_threshold = 10
operator = "above"
query = string_from_the query_field
---
policy_name = TOP
alert_name = "Top-prod ELB-4xx"
critical_threshold = 10
warning_threshold = 10
operator = "above"
query = string_from_the query_field
---
policy_name = TOP2
alert_name = "Top2-prod ELB-4xx"
critical_threshold = 10
warning_threshold = 10
operator = "above"
query = string_from_the query_field
---
policy_name = TOP2
alert_name = "Top2-prod ELB-4xx"
critical_threshold = 10
warning_threshold = 10
operator = "above"
query = string_from_the query_field

There might be numerous policies or alerts.
How can I iterate over this type of map and get the correct values? Anybody?

Thanks in advance

Here is how to loop over a map

output "foobar" {
  value = [for instance in var.pol: keys(instance)]
}

Which returns

  + foobar = [
      + [
          + "Top2-prod CPUUtilization",
          + "Top2-prod ELB-4xx",
        ],
      + [
          + "Top-prod CPUUtilization",
          + "Top-prod ELB-4xx",
        ],
    ]

While this won’t solve your question completely, it should help get closer to a working solution.
