There is not a specific report that will indicate incidents created specifically on netflow data. In general, CS-MARS uses netflow data to detect anomalous network behavior through statistical analysis. Over time, CS-MARS develops a baseline of traffic behavior using the netflow data. Once the baseline is developed, CS-MARS will compare netflow data against the baseline and alert when an increase in traffic is detected. This is outlined here:

The CS-MARS 'Sudden Traffic Increase...' incidents are related to netflow-based analysis.
These details are used in conjunction with other events received by the CS-MARS for more effective correlation and incident generation.
