Analyzing Page View Telemetry

INTRODUCED IN: Business Central 2020 release wave 1, version 16.3. Available in extension telemetry from version 18.0.

Page view telemetry gathers data about the pages that users open in the Business Central client. Each page view tells you how long it took to open the page, information about the user's environment, and more.

Use the data to gather statistics about system usage and also troubleshoot performance issues caused by the users' environments.


In Application Insights, telemetry about page views is logged to the pageViews table and not the traces table like other Business Central traces. This also means that you can use the built-in pages in the Usage feature of the Application Insights to investigate how users interact with the Business Central environment. For more information, see Usage analysis with Application Insights.

Page opened: {alObjectName}

Occurs when a page has been opened in the client.
