Investigate source of network traffic through NAT Gateway in - VPC

[jaronheard]

The NAT Gateway in the - VPC has been processing between 13 and 15 terabytes of data each month since September 2019. We'd like to know what the source of this network traffic is and whether it is something that could be removed or reduced.

AWS has docs on how to identify sources of traffic and identify which services are producing those sources of traffic

Saw this in my email so did want to check on something but don't think is actually source.

We were running some postman collections as synthetic monitors via a travis cronjob but neither the timeline or amount of data seems to correlate

Based on commit history believe was started in Oct 2019, and were disable about 4 months ago (i forgot if i had or was another cause) based on last runtime, and don't think would have resulted in amount of data processing
