This article is for all School Manager users.
What is the Noise feature and how does it work?
The Noise feature controls whether data that are displayed are not critical to understanding the information generated by School Manager about users' activities on the school network. These non-critical data may include network security services (antivirus), software updates, connections made by hardware on the network (printers, wi-fi signal boosters), and other traffic that are essential to existing services (synchronizing data, file sharing).
Can I enable or disable Noise?
You can enable or disable this feature by selecting or deselecting the Noise checkbox next to the date selector on the toolbar.
When Noise is enabled (checked), then the Content Delivery Networks (CDN), advertising and tracking data included in School Manager reports and charts. In the following example, noise data from CloudFront, a content delivery service owned by Amazon, is included in the Apps and Websites chart. For example, you can hide or show the "Noise" in the Apps and Websites report.
When Noise is not selected, then advertising, trackers, and CDN data are removed from the charts and calculations.
