Per-Domain Node License Utilization Threshold Alerting

NetBrain currently does not provide a per-domain breakdown of node license utilization, nor does it offer automated alerting when utilization approaches a defined threshold. Administrators must manually track and calculate utilization across domains on a recurring basis to avoid unexpected capacity issues. This enhancement would provide a capability to export node license utilization broken down by domain and trigger an email alert per domain when utilization crosses an administrator-defined threshold. This would reduce manual monitoring effort and give administrators advance notice to plan for additional license capacity before limits are reached.
