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...

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.

    Good morning,

    Another question around capacity.  We currently have ATA implemented in a few of the domains that will be migrated to ATP.   Is there any data we can use in ATA to forecast the capacity for ATP?

      bryanb I don't think so... they work very differently, because AATP is cloud based, it needs to transmit more data to the cloud compared to ATA which saves a lot of data locally.

      Also, AATP has lot more data sources, so this is also a factor. at best, measuring the traffic fro teh gateways to the Center will give you maybe a min capacity, but I never tried that.
