I had an incident where I noticed for a node (a cisco switch) the UDP table in Orion web console wasn't updating. For several switch ports in UDT it had machines showing connected (currently connected) BUT they were not physically connected for months! I checked the ARP table and nsloookup etc..
In UDT Settings > View UDT Job Status the node displayed twice (layer 2 and layer 3). The last run and next run were dated today being 30 minutes apart. I manually kicked off a "poll now". Within a minute the info was updated in UDT and displayed corrected as it should of already.
Now, where do I go to attempt to locate if this problem is occurring for other UDT enabled layer3-layer2 nodes?
