Refresh Poller Table Per Cycle
This setting is for a single poller systems only to rebuild the poller output table on each polling cycle to prevent the memory table from swapping on very large systems with large databases that could use swap.
Data Collector Replication
Poller Sync Interval
By default, the main Cacti Data Collector will cache the entire web site and plugins into a Resource Cache. Then, periodically the Remote Data Collectors will update themselves with any updates from the main Cacti Data Collector. This Resource Cache essentially allows Remote Data Collectors to self upgrade. If you do not wish to use this option, you can disable it using this setting.
Disable Automatic Full Sync on Upgrade
By default, upon upgrading the Main Cacti system, it will perform a Full Sync to all Data Collectors. This process may be time consuming. Therefore, to allow upgrades to be completed quicker, we provide this option. Note that if this is disabled, the Cacti administrator must force this process from the Data Collectors interface after upgrade.
