Has anyone else encountered an issue like this:
You have 1000 HCO node licenses; you're using 900 of them to monitor your Linux systems using SNMPv3.
You run a nightly SNMP discovery service on 250 addresses. The plan is to automatically add network devices that meet a filter criteria (to add newly up interfaces matching a certain name).
The discovery completes and finds all the existing nodes (perhaps a few new ones too).
The automatic import of the nodes fails before checking whether they are duplicates of existing nodes.
It appears to assume you only have 100 HCO node licenses remaining and it had discovered your 250 nodes that could be brand new. They were mainly existing nodes, but that process of checking does not happen - it assumes you will exceed your licensed node count.
Now, imagine you have 3500 Linux nodes spread across 4 /18 subnets who are vpn connections to each node.
interestingly with a per poller licensing model this was not a problem - we ran the discovery across each /18 subnet and auto imported the nodes without issue - as the license was not about the number of nodes rather it was about the pollers being licensed.
