We are running UIM 20.33 and the OC/Inventory does not load at all.
Alarms and groups are working fine, however, when navigating to the inventory, after the total number of devices shows in the OC UI, the actual list of the devices is never presented and it eventually fails showing an error that " no items to show ".
Limit of Chrome browser in combination with large environments (Eg. 150k + Devices in inventory)
Release : 20.3.x
Component : UIM OPERATOR CONSOLE - WASP & CORE
The issue only happens with Chrome, and does not happen with Edge or Firefox. The immediate workaround would be to use Edge or Firefox to avoid the issue.
The long term solution would be to upgrade to UIM 20.4 CU2 which introduces "infinite scrolling" with inventory. This allows a faster rendering of the inventory as devices are only loaded 50 at a time and they keep loading as you scroll down with the cursor.
