Currently we have implemented the Nagios core 3.2.1 with around 300 hosts.
What is the maximum host capacity for that version.
Also tell me the service capacity as well.

There isn't a set "maximum host capacity" in Core, it is really limited by the server speed it is on and a variety of other factors, but that said, I have seen Nagios core 3.2.1 running with well over 5000 hosts configured.

Nagios Core 4+ can handle substantially more.
