check_nagios is not very complicated. Per the manpage, it wants to be
pointed to status.log, not nagios.log or status.dat. The reason for that is
simply that it checks that the last entry in the log is within N minutes of
the current time (set by -e 5 to 5 minutes). It also checks that a Nagios
process is present in ps. What kind of examples are you looking for?
