Data Analytics — VPC Flow Logs

This how-to guide shows you how to apply transformations to your VPC Flow Logs.

In our Data Ingestion - VPC Flow Logs guide, we showed how to load your data into Upsolver, refine it, and prepare it for transformations. Below are examples of transformations you can apply to your refined data.

SELECT RequestDateTime, RemoteIP, Requester, Key 
FROM s3_access_logs_db.mybucket_logs

Show all operations performed by an IAM user

SELECT *
