Hi
We do have customers that have both SNTC & NOS and share a single collector, but not all collector configurations are supported, especially since NOS deployments are very customizable in terms of the services they deliver. It usually requires the NOS team (which deploy and maintain their collector) and the SNTC deployment team to assess the situation and make a determination.
In terms of what NOS adds to the data & information already collected by SNTC, NOS is a much different service than SNTC because it is high-touch with Cisco NCE assigned to the account. Focus is around Optimization. There is core NOS (route switch) and then tons of options (data center, security, wireless, Collab, etc.). Some of the deliverables overlap (specifically the alerts-eox, fn, psirt), but the approach in NOS is different. There is more of a consulting approach it it. For example, EOX is about 5 year roadmap plan for what is coming EOL in next 5 years and lifecycle planning. PSIRT includes more detailed recommendation consulting on what to do to address the impacts to the customer. Beyond alerts, some of the common automation-enabled deliverables include Configuration Best Practice Analysis, Customer-Specific configuration compliance analysis, Syslog analysis, SW Compliance reporting/tracking, unidentified inventory reporting, topology diagramming, Network Improvement Plan, and Network Audits.
