nac-analytics

Today this tool 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>.

$ nac-analytics nd delta -output text
