Tell me, I use Dude on RouterOS x32 on pfSense.
About 500 devices were added to the monitoring.
Accessibility checks are performed exclusively by the ping tool every 1 minute.
The client part is installed on Windows 10 x64.
So, when you double-click on a device in the Dude client, it completely freezes for 1 minute. And so it happens at all.
Tell me what to watch. Disconnected already all unused.
