Hello,
Since upgrading to recent versions of NetXMS, I no longer receive "SYS_NODE_DOWN" events when a device goes offline. Instead, I always receive "SYS_NODE_UNREACHABLE" events—even when the affected node is simply powered off and there are no other network devices between the NetXMS server and the node.
Previously, "SYS_NODE_DOWN" would be triggered in these cases, but now it seems NetXMS always classifies the situation as "UNREACHABLE," regardless of the actual network topology or the absence of intermediate devices.
Has anyone experienced this behavior? Are there specific configuration parameters or changes in recent versions that could explain this shift? Any advice on how to restore the previous event behavior would be appreciated.
Thank you!
			
			
			
				Hi, 
Sorry, you post got a bit lost. 
Current version is 5.2.3, I don't think there were any changes related to this, but anyways, pls upgrade to is to that we are on the same page. 
Then, when you observer such situation, pls check Event log for a node that had SYS_NODE_UNREACHABLE event. Check Root ID column for this ID, is it 0 or not? If not, pls find event with that ID. Pls show screenshots
