I've been noticing a weird issue with one of our pollers when we unmanage/manage nodes in our environment. We will usually set an unmanage maintenance window that is usually a month out - the nodes change to the Blue circle with the X in it, but within 24 hours, the node has reverted to another status. In my case today I have 3 that are showing as down and 1 that is listed as UP, but the Unmanage button greyed out when the node is selected. Has anyone out there experienced something like this, and if so what did you do to resolve it?
Maybe if you read in log file NPM you see the reason to show it.
the node SEPS2KDEV it´s work normal? If yes, can you to run configurations wizard for resolutions this.
