Measured event size · Database
Oracle Database log size: 1,030 bytes per event
The average Oracle Database event is 1,030 bytes, measured from samples of its logs. A database source typically produces 100 events per second per device, bursting to 1,000: audit policy decides this, not workload. The rate is an informed estimate; the size is measured.
What that comes to
One device, raw bytes, at the typical rate for a database source.
| Period | At 100 events/s | At the 1,000 events/s burst |
|---|---|---|
| An hour | 371 MB | 3.7 GB |
| A day | 8.9 GB | 89 GB |
| 90 days | 801 GB | 8 TB |
| A year | 3.2 TB | 32.5 TB |
A day of Oracle Database logs from one device at the category's typical rate, 8.9 GB, is about 2 times an hour of YouTube in 4K.

Measure a sample of your own
The figure above is an average; yours will differ, and for Oracle Database what moves it most is this: audit policy decides this, not workload. The profiler reads a sample from Oracle Database in your browser, line by line, one event per line, and reports the bytes per line to set against it. Nothing is uploaded.

Logcaliper, free on iOS, has these sizes and rates built in and sizes a whole list of sources at retention: storage, cluster capacity, nodes.
