use Nagios::Config;
use Nagios::StatusLog;
use Benchmark ':hireswallclock';
use Getopt::Std;
=head1 NAME
config_status_demo.pl - demonstrate using Nagios::Config and Nagios::StatusLog together.
=head1 USAGE
perl config_status_demo.pl -c /etc/opt/nagios/nagios.cfg -l /var/opt/nagios/status.log
=head1 NOTES
Please send the benchmark outputs to duncs@cpan.org so I can see how the
performance is on boxes and configs other than my own.
This setup is very sensitive to mistmatches between the configuration and the status log.
