System logs are internal diagnostics generated by Apple devices that contain data on all the device internal measurements and decisions from the internal Wi‑Fi systems.
They provide insight beyond signal strength alone.
What Logs Unlock in nOversight
When logs are imported, you can see:
Signal‑to‑noise ratio (SNR)
Retry rates
Congestion levels
Roaming reasons and steering behaviour
Taking a log directly after a walk test, will allow you to enhance the data and see a lot more detail about your Wi-Fi performance.
