Site Attribute-Based Filtering for Health Check NI Assignment

NetBrain currently does not provide a way to selectively apply Site-Level Health Check Network Intents based on site attributes, requiring the same NI logic to be applied uniformly across all sites regardless of differences in device types, protocols, or WAN architecture. This enhancement would allow administrators to define site-level properties, such as architecture type or connectivity model, and use those properties as criteria to scope which sites a given Health Check NI applies to. This would allow customers operating multiple site types to tailor health checks to the devices and protocols relevant to each site category, reducing irrelevant alerts and manual NI management effort.
