What Is SPA?
Base Pages vs. Virtual Pages
For SPAs, you will have base pages, virtual pages, and Ajax requests. From Pages & AJAX Requests, you are able to view all three types and details for each as shown below.
SPA1 and SPA2 Monitoring
The table below describes the support for SPA1 and SPA2 monitoring:
|SPA1||AngularJS 1 only||Yes|
Which SPA Monitoring to Use?
View SPA2 Monitoring Data
You can view end user response time (EURT) for SPAs in many places in the Controller. The EURT measures the time from when the user navigates to a virtual page until all resources are downloaded for the page. See SPA2 Metrics for more information.
The Browser Snapshots tab displays a list of different types of pages as shown below. You can view relevant metrics for all the pages and other metrics for base pages and Ajax requests.
Snapshot Details: Summary
To get to the Snapshot Details dialog shown below, you double-click one of the browser snapshots in the Browser Snapshots page. The Summary tab is the default tab for the dialog, and it gives some additional information such as the parent page URL.
Snapshot Details: Resource Details
The Resource Details tab shown below provides details about resources such as the number and type of resources, the domains where the resources were requested, and resource load times.
Pages & AJAX Requests
The Pages & AJAX Requests page as shown below enables you to view the number of requests for each type of page and the average metrics per page. You can also select which page types to view, such as virtual pages.
Page, Ajax, and Iframe Dashboards
From the Pages & AJAX Requests page, you can double-click a page to view the Page and IFrame Dashboards. Dashboards for each page type will have a Summary section displaying the average metrics as well as a Key Performance Times section showing the requests and the metrics on a timeline.
The tabs below show the differences in the dashboard for each page type.
Base Pages Base pages contain timing metrics such as End User Response Time, Page Complete Time, and Visually Complete time. Virtual Pages Virtual pages provide the resources requested. AJAX Requests Ajax Requests include a more limited set of timing metrics as well as Ajax-specific section for the AJAX Response Download Time and the AJAX Callback Execution Time.
