Netflow from 2 different ASAs



Hi, we are testing out PRTG and I have added 2 Netflow v9 sensors from our 2 ASAs (Prod and DR). It appears like the we are receiving the flows from both ASAs but when I look at reports such as "top talkers" it appears like PRTG is combining the flows so that I am seeing flow data from both production and DR in the same graph. Is it possible to separate these so that I can see a single graph representing flow data from prod and another graph representing data from DR? Thanks, Jim

Hi there,

When you configure no "Sender IP" in the sensor's "Settings" tab, it will process all flows it receives on the configured port. By configuring a sender IP in each sensor, you can make sure that each sensor only processes flows from the respective flow sending IP.

Kind regards,
