A snapshot captures the state of an Acoustic Overstat-enabled web page, including all of the data that is typically displayed in Acoustic Overstat overlays.
Saving captured snapshots to the Snapshot gallery simplifies access to Acoustic Overstat data.
Before you create snapshots, either clear the browser cache before a page load or disable browser caching to avoid gaps in the snapshot. Clearing the browser cache or disabling browser caching is recommend regardless of which method you are using to create snapshots.
Sometimes a snapshot might be taken of a URL that you don't expect. For example, if you have a screen that needs to be logged into before use, the snapshot might be taken of the log in screen instead of the screen you want. You might see a warning message in Experience Analytics asking if you want to capture a different URL that is listed on the warning message. You can choose to capture the listed URL or you can use the Firefox extension instead.
Note: Snapshot capture does not work on hybrid applications.
Create snapshots with the Firefox snapshot extension
If you are creating snapshots with the Firefox extension, you need to be running Firefox version 38 or higher.
Firefox version 38 or higher is the only browser that is supported by Snapshot.
Use the following procedure to create a snapshot with the Firefox snapshot extension.
- Visit the web page that you want to create a snapshot of.
- Click the Capture (camera) icon on the Firefox toolbar to open the snapshot capture window.
- Click Ready to capture (for static content) to use the keyboard shortcut (for dynamic content) to take a snapshot of the web page. This creates a snapshot and saves it to the Snapshot gallery.
A view of the page in the snapshot gallery includes quantitative information that is related to visitor's interaction with the page.The views field shows the number of times the screenView URL for the captured page was viewed.
For example, if a visitor viewed the page two times over the course of a session, that counts as two views.
- Optional: Click Validate page.
The Validate page feature checks that the UI SDK is integrated on the page that you are capturing and that the page doesn’t have problems that might cause the snapshot to fail.If the Validate page operation determines that the SDK is not present of it detects a problem with the page itself, it displays a message and an explanation of the problem.
- Enter the Snapshot name and move the snapshot to the appropriate stack.
