That's a trick question. There really are no 'settings' shown here. What
nagios is showing you is current levels of performance based on the
settings in your nagios.cfg file. The 'Rough guidelines' at the bottom
is a recommendation for your max_concurrent_checks.
Open nagios.cfg and find your max_concurrent_checks definition. Does it
fall within the recommended range? If not, then try setting it at the
bottom and/or top of the range and then observe your performance again.
Tweak as necessary. Repeat process.
