How to debug skyrocketing monthly data usage?

I am trying to figure out why my monthly data usage suddenly jumped by 6X last month, and is continuing through this month.

My average monthly usage Oct 2025 - Jul 2026 was 395 GB. August 2026 it jumped to 2,356 GB. It has continued at that rate through September.

What tools are there to help me figure out what is going on?

They don't offer any. See https://forums.xfinity.com/conversations/your-home-network/individual-device-data-usage/659ece3a8f01ac51ddb8ffb3?commentId=65a17a11f961c6163a36783a. It's all up to you.
