Once you've got your logs, a typical challenge is how to process, and visualise them.
This usually happens when you try to address visualisation as a whole. But until good filters and multi-stage-analysis are in place, there is just too much data, too much information, and you will be left struggling with the sheer size of the data you are looking at.
The key is to create an environment where we are only querying an subset of the data, with fast queries and REPL like workflow.
One of the ways to manage this is to start with a small AppSec question (ideally codified as a Test).
