We have an issue regarding the "Overall Running vs. Startup Config Conflicts" resource. All JUNOS devices (Since JUNOS doesn't support running and startup config) are being displayed as unknown. This issue has been known for quite some time and yet no action has been taken.
Suggested solution: JUNOS devices can be discarded with filtering the resource as shown below. Also it is a good idea to support "Filter Nodes (SQL)" all the other resources in NCM.
