Can we make sure that SNMP is enabled and configured with the same community string on those two oddballs?

Have we tried to disable the local global option of: "Add only saved host entries to Reconnect list"? If this doesn't have the desired effect, could you perhaps post a screenshot of what we're seeing?

Alerts should be automatically imported on upgrade. A support ticket may be the best path forward: http://www.solarwinds.com/support/

Very likely you would be able to directly upgrade from 10.7 to 12 (though this is not yet finalized.) NPM 11 has the awesome new QoE dashboard available: NPM 11.0 Release Candidate Now Available!

Firstly we may want to check on the F5s themselves to see if they are seeing the same stats. Should be available through the UI. Perhaps the F5s are hitting their connection limit and starting to drop traffic?

Having SNMP enabled on the host is requisite for volume info. This thread may be helpful: http://thwack.solarwinds.com/message/196951#196951

Surely- unmanage tasks can be scheduled: Scheduling unmanage task for nodes, interfaces and applications

Depending on the device, Serial/AssetTag fields may be different. If you have 10.6, you could create custom table similar to the below:

If you edit the created MSI with Orca (Orca.exe (Windows)) check out the "Registry" table for the configured value.
