We only charge for the resource type for the corresponding product. For example, if you have a domain.com and sub.domain.com we would charge you $1 for each.
If you are using the monitoring module and you ad an IP, a Domain, and a subdomain we will charge you $3 for all three resource types.
We do not charge for arbitrary metrics like frequency of checks, enhanced records, or network utilization. We charge one flat fee.
