Currently "converged" reporting of DataAggr(snmp) and NFA(flow) detail is limited only to interface-level-pages.
This limitation is problematic in several cases;
1. Often Physical-Serial-Links are the Basis for CBQOS polling but are not netflow-sources.
2. Often ePVC-circuits are netflow-sources but IOS does not register errors and discards.
3. Many Sites will contain 2+ flow-sources (IMA, and/or carrier redundancy), an aggregation is possible for joint-NFA-reporting, but trends of an NFA-aggregation will not show DA(snmp) stats.
The only true and simple way to see, and email, and archive..., is for the 3 main NFA view-types to be supported from the summary/group-context type.
Namely, this change would allow dashboard-template-pages to combine any mix of;
DataAggr views - top-interface(DA), top-errors(DA), top-CBQoS(DA), etc.
Also mutli-interface-trends, multi-CBQoS-policy-trends, etc.
with ADA-Site-Views - Top-performance-by-application
with NFA's core of interface-views - Stacked-Proto-trend, Top-Hosts, Top-Conversations, & Stacked-TOS-Trend.
This need not apply to multi-interface groups (i.e. my-DC-1), but for any given group to support this feature it could simply contain any number of devices (included-children for LAN interfaces & CBQoS classmaps), but just one single NFA-WAN-Link or NFA-Aggrregaion.
