VMware ESX log size: 80 bytes per event
The average VMware ESX event is 80 bytes, measured from samples of its logs. A server source typically produces 30 events per second per device, bursting to 250: generic appliance OS, no process auditing. The rate is an informed estimate; the size is measured.
What that comes to
One device, raw bytes, at the typical rate for a server source.
| Period | At 30 events/s | At the 250 events/s burst |
|---|---|---|
| An hour | 8.6 MB | 72 MB |
| A day | 207 MB | 1.7 GB |
| 90 days | 18.7 GB | 156 GB |
| A year | 75.7 GB | 631 GB |
A day of VMware ESX logs from one device at the category's typical rate, 207 MB, is about 3 times an hour of Spotify.

Measure a sample of your own
The figure above is an average; yours will differ, and for VMware ESX what moves it most is this: generic appliance OS, no process auditing. The profiler reads a sample from VMware ESX in your browser, line by line, one event per line, and reports the bytes per line to set against it. Nothing is uploaded.
