Our environment has 2 DCs with capacity set to 750,000 and would like to increase it to 1,000,000. There appears to be plenty of capacity available on the DCs. CPU utilization on the DC's are a consistent 20% and memory utilization is just under 40%.
Release : 20.2
Capacity displayed for the Data Collectors is only used for the display. It does not represent the actual capacity of the DC and in no way will stop the DC's from receiving new devices to poll. The only downfall is the display will display over 100% utilization if you go above the capacity in the GUI.
