Any ideas why I cannot re-discover nodes? They result in this error after going through the whole discovery phase.
Their assigned poller is the same server as what is doing the discovery. They are all the same poll method (SNMP).
I have moved your question to the NPM forum where you get an answer more likely.
In the meantime, could you perhaps add more background? Screenshots?
Thanks,
Jiri
If the node is already in NPM then the import is going to skip over them as they already exist. If you are looking to update the information on the nodes via a discovery, a rediscovery is run on all monitored devices every 30 minutes by default. The node discovery is for adding new devices to be monitored, or new interfaces to existing devices, but the node itself will be skipped over should it exist.
