Default Availability/Reachability for all new Devices.The method Cacti will use to determine if a Device is available for polling.<br><i>NOTE: It is recommended that, at a minimum, SNMP always be selected.</i>
When operating multiple Data Collectors in Cacti, Cacti will attempt to maintain state for key files on all Data Collectors.This includes all core, non-install related website and plugin files.When you force a Resource Cache rebuild, Cacti will clear the local Resource Cache, and then rebuild it at the next scheduled poller start.This will trigger all Remote Data Collectors to recheck their website and plugin files for consistency.
