Your wish is understandable but "ppid = 1" is not sufficient. Run

/usr/lib/nagios/plugins/check_procs -C nagios2 -c 1:1 \
-a '/usr/sbin/nagios2 -d /etc/nagios2/nagios.cfg' -p 1
(-a is required for paranoid people only)

in a constant loop and see how the number is going up and down. As far
as I can tell there is no easy way to distinguish between "forgotten
daemon" and "forked daemon running a test". The master process should
not have children but checking for that requires careful operation,
think of races.
