Getting a record of all coredns records as a prometheus metric

Question

Help with ideas how to implement sending all records that coredns receives as a metric in prometheus, I had an idea through a script to first query and then send to pushgateway but such an implementation limits me to record labels for each unit that I receive from the DNS list. I also had an idea to send unique records like AAAA or A from logs coredns, but no idea how to implement this mechanism.

I tried to request all records through a script and then send them to pushgateway, but ran into a problem with labels limitation.

def resolve_dns_name(ip):
    try:
        dns_name = socket.gethostbyaddr(ip)[0]
        logging.info(f"DNS имя для IP {ip}: {dns_name}")
        return dns_name
    except socket.herror:
        logging.warning(f"Не удалось разрешить DNS имя для IP {ip}")
        return "Неизвестно"

def get_instance_id(svc):
    return "some_unique_instance_id"

def push_metric_directly(base_metric_name, labels, value, dns_name, namespace, metric_id):
    metric_name = f"{base_metric_name}_by_dns"
    labels['dns_name'] = dns_name
    labels['namespace'] = namespace
    labels['metric_id'] = metric_id
    labels_str = ", ".join([f'{k}="{v}"' for k, v in labels.items()])
    data = f'{metric_name}{{{labels_str}}} {value}\n'
    response = requests.post(PUSHGATEWAY_URL, data=data, headers={"Content-Type": "text/plain"})
    if response.ok:
        logging.info(f"Метрика {metric_name} с labels {labels_str} успешно отправлена в Pushgateway.")
    else:
        logging.error(f"Не удалось отправить метрику {metric_name} с labels {labels_str} в Pushgateway: {response.status_code} {response.reason}")
