snmpcollector probe GUI response on every operation is very slow.
When GUI start "Loading" to reflect any changes, it takes for a few minutes to finish.
UIM Server - 8.4 / 8.4.7 / 8.5 / 8.5.1 snmpcollector probe 3.31 on a secondary HUB.
Undetermined. We are investigating the cause of the problem.
Please deploy distsrv probe on the secondary HUB where snmpcollector probe is running.
You will get faster GUI response with the workaround.
We have identified the same problem for icmp probe as well. The workaround is also the same.
