Network Capacity Planning Azure ATP Sensor to Azure

Hello,

Can you tell me if the capacity information "we send only 1-3% of the total traffic to the service for processing." is current?  

If so, would I use the network performance data captured in the capacity planning tool?
https://docs.microsoft.com/en-us/azure-advanced-threat-protection/atp-capacity-planning

Would I use 1-3% of Max Packet /secs column?

Thank you

    bryanb That would be a very very rough estimation, as the actual values heavily depends on the  DC's traffic mix.

    Honestly the only way to really test it is post deployment.
    What I can tell you is that I never heard about a customer where the actual upload rate became an issue...

      EliOfek   Thanks for the response. 

      We have several hundred domain controllers and we need to make sure we forecast the impact to our WAN and outbound internet connections.  

      Is there a better way to estimate outbound traffic capacity?

        bryanb The best way will be to install the sensor on some of the busiest DCs and measure post deployment the impact on outgoing traffic from those machines to the internet. assuming your network traffic mix is similar across the sites, you will get more accurate numbers...

        Again, the impact should be relatively small, so most customers don't even bother to check it.
