User sessions API - User session structure

This page provides descriptions of all possible fields that a user session might include.

Be aware that with Dynatrace version 1.204, we’ve introduced new error counts in USQL and Session export for every user action, which are fully consistent across Dynatrace. In turn, we'll deprecate the following error counts with Dynatrace version 1.217:

useraction.errorCount — Only includes JavaScript errors.
useraction.httpRequestsWithErrors — Only considers server-side errors.
useraction.failedXHRRequests — Only considers failed XHR calls made in your end user's browser.
useraction.failedImages — Will be included with the new requestErrorCount.

Read more about how to best replace existing error counts with the new ones.
