You're missing:
host_perfdata_file_processing_interval
service_perfdata_file_processing_interval

You will not need all of them. There are two ways of doing it. You can
either have nagios run a command after each check (The perfdata is
passed on the command line) or have Nagios write to a file (which can be
a pipe as well). Among the parameters you mentioned some of them are for
  a perfdata command while others are for a perfdata file.

If you choose to write to a file, you can optionally have nagios run a
command every *_perfdata_file_processing_interval to process the file
(Nagios will reopen the file once the command terminate, so the best way
to do it is to move the file away, fork and then process it).

Note that running a command on each check will become a bottleneck soon
enough if you're doing a lot of checks, so writing to a file or pipe is
preferred.

If you have good Perl knowledge you should take a look at my OCP_Daemon
which could be a good starting point if you want to write your own
daemon to process the data:
