The Fingerprints tab provides detailed information about fingerprints used by ExtremeAnalytics to identify application flows. A fingerprint is a description of a pattern of network traffic which can be used to identify an application. They can be created based on flow, application or application group, or a destination address. For applications such as Facebook and Google, multiple fingerprints are included to capture the different ways these applications can be used.
Fingerprints are created and stored on the ExtremeCloud IQ Site Engine server. When a fingerprint is changed or enabled, a flag is raised on the ExtremeAnalyticsengine to show it needs enforcing. Access the Browser from the ExtremeCloud IQ Site Engine Analytics tab.
There are two types of fingerprints: system fingerprints and custom fingerprints.
System fingerprints are provided by ExtremeCloud IQ Site Engine. They cannot be deleted; however, they can be modified or disabled. When a system fingerprint is modified, it results in a new custom fingerprint that overrides the original system fingerprint.
Custom fingerprints are either new user-defined fingerprints or modifications of system fingerprints. Custom fingerprints can be deleted. If a custom fingerprint was overriding a system fingerprint, then deleting the custom fingerprint will reload the original system fingerprint.
