# Enhancing with System Logs

## What Are System Logs?

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.

***

## Standard vs Pro Behaviour

System Logs can only be used with a Pro subscription.

#### Standard (Free)

* Live Wi‑Fi visualisation
* Walk tests up to 1 minute
* Data shown live only
* Results are not saved
  {% endcolumn %}

{% column %}

#### Pro

* Unlimited test duration
* Save walk tests
* Compare before/after changes
* Import and analyse Wi‑Fi logs
* Export CSV results
* Mac deep‑dive views

Saving results allows you to adjust, re‑test, and compare — the fastest way to improve Wi‑Fi.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://numerous-networks.gitbook.io/noversight-docs/noversight-tutorial/noversight-for-ios/enhancing-with-system-logs.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
