Inspec profile for system and firewall validation

Hi All,
i am planning to write a profile to validate the system parameters like CPU, MEMORY…etc and to do the firewall testing validation. in my scenarios i want to do these on newly provisioned servers.

my query is around managing attributes in file specially i may have multiple servers (50) & ports (1-5 per server) to be tested for.

any pointers in this regards would be appreciated.
