Google Audit log size: 400 bytes per event

The average Google Audit event is 400 bytes, measured from samples of its logs. An application source typically produces 100 events per second per device, bursting to 1,000: web access logs high, service audit trails low. The rate is an informed estimate; the size is measured.

What that comes to

One device, raw bytes, at the typical rate for an application source.

A day of Google Audit logs from one device at the category's typical rate, 3.5 GB, is about the size of an hour of Netflix in HD.

Size your own

Raw bytes, before compression, indexing overhead and replication.

Measure a sample of your own

The figure above is an average; yours will differ, and for Google Audit what moves it most is this: web access logs high, service audit trails low. The profiler reads a sample from Google Audit in your browser, line by line, one event per line, and reports the bytes per line to set against it. Nothing is uploaded.
