So, I'm pretty sure this just stopped working for me, and I confirmed that others have seen this also.
In any recent version of Solarwinds, including 2024.2, you can go to "Configuration Management" and start selecting nodes on one page, and then go to another and select some more and it adds that selection to the nodes you selected on the first page. You can see this at the top where it will say "X node(s) selected", lets say X was 5 on page 1, when you go to page 2 its still 5 until you add more, and it will increase your selection, not reset it.
The "Manage Nodes" page also used to work this way also. However, it's not any more. Now, let's say you sort by Vendor, and under VendorA you select 5 nodes, and then go to VendorB and select another 5 nodes. When you change pages, your "5 node(s) selected" goes away, and when you select another 5 nodes on the VendorB page, you now have 5 nodes selected instead of the 10 you wanted.
Please fix this! Bring back our selection persistence in Node Management!!! This is a infinitely useful feature that is one of the great things about Solarwinds and is useful not only in the "Configuration Management", but in "Manage Nodes" too!!
