With check_nrpe you call the remote daemon.
Parameters of check_nrpe is, amongst others, the check you want to perform on the remote host.
(use "check_nrpe" to see the parameter description)
One Parameter would be e.g. check_procs, which would be found in the remote
/etc/nrpe.cfg, where the actual check is called with the parameters for this check.
For check_proc you can use "check_procs --help" to get info,
which produces (amongts others):

"RANGEs are specified 'min:max' or 'min:' or ':max' (or 'max'). If
specified 'max:min', a warning status will be generated if the
count is inside the specified range"

Hope this helps
