I've been using Dude since 2007 and it's always been a good way to monitor the network. But we are in trouble, our network has grown a lot and I thought it was a database bug, we installed Dude on another Routerboard, today we have two Dude running, each in a CCR1036. The problem is related to the devices that turn red and does not appear in the Outages tab the correct time of the problem and when it appears as resolved, we can not remove the resolved ones. This is very important to know the time of a problem and once resolved we need to clear the resolved ones.

I have version Dude arm 6.46.1 on a RB450Gx4 with same issue that the alarm shows in the Dude Network Maps location as red, device down, but in the Services and then TAB Outages section the alarm simply does not show at all. Typically when the alarm clears it may then well show up as a resolved historical alarm in the menu section Services, TAB Outages. RB450Gx4 has plenty of CPU power and memory to easily do the Dude service with hundreds of devices (400) with maximum 16% CPU. So I do not know either how to fix this issue or know of a work-around.
