Cisco vPC doesn't seem to capture the following:
- auto-dependencies
- aggregated gateways
Monitoring improvements could include:
- Aggregating vPC port-channels for traffic
- could be a dropdown or checkbox when interface is discovered as part of a vCP for "show vPC aggregate throughput"
- Adding a link to vPC peer when discovered
- Listing orphan hosts
- Alerting on configuration inconsistencies between vPC peers (especially interface-level)
- Alerting on unexpected traffic volume across peer-link
I don't think any of the above are achievable without additional NPM functionality
