Proxy log rate: 600 events/s per device
A proxy source typically produces 600 events per second per device, bursting to 3,000: one record per HTTP request, tracks user count. The rate is an informed estimate, a starting point for a sizing, not a measurement; the event sizes below are measured.
Measured sources in this category
Average bytes per event, measured, and one device's volume at the typical 600 events per second.
| Source | Bytes per event | A day | A year |
|---|---|---|---|
| Netskope Alert | 2,591 | 134 GB | 49 TB |
| Bluecoat | 300 | 15.6 GB | 5.7 TB |
At the median size, a day from one device, 74.9 GB, is about the size of a day of James Webb data.

Measure a sample of your own
The figure above is an average; yours will differ, and for proxy logs what moves it most is this: one record per HTTP request, tracks user count. The profiler reads a sample from proxy logs 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.
