nac-analytics

Formerly nac-nd. Today it covers Cisco ACI via Nexus Dashboard 4.2.1+; the intent is to grow beyond Nexus Dashboard and add support for additional Cisco products, so one tool can drive change analytics across platforms.

CLI for change analysis on Cisco ACI fabrics via Nexus Dashboard 4.2.1+.

Commands are grouped per Cisco product: nac-analytics <product> <command>. Today the product is nexus-dashboard (alias nd); more products are planned.
