Description of the uAInSessionHelper.exe Helper Process

Some information is only available to processes running in a user’s session, not to services running in session 0. In order to be able to collect such data, too, uberAgent makes use of the helper process uAInSessionHelper.exe.

uAInSessionHelper is a lightweight and short-lived process that collects specific data, sends it to the main service and then exits.

How Often is uAInSessionHelper.exe Run?

uAInSessionHelper is run for the following reasons:

  • To collect information about a UWP app
    Frequency: once when the app is started
  • To collect Internet Explorer performance data
    Frequency: once per timer interval of the metric BrowserPerformanceIE
  • To collect UX metrics for SaaS and web apps in Chrome
    Frequency: once per timer interval of the metric BrowserPerformanceChrome
  • To collect GPU performance data
    Frequency: once per timer interval of the metric GpuUsage

Common Errors

Class Not Registered

You may see messages like the following in uAInSessionHelper’s log file:

2015-09-04 22:16:48.140 +0200, ERROR, HK, XA1$, 1856, IE Performance, Action 2 failed with: -2147221164
2015 - 09 - 04 22:16:48.142 +0200, ERROR, HK, XA1$, 1856, GetBrowserPerformanceIE, Failed (2) with: Class not registered

The root cause for these errors is that uberAgent can only determine IE performance per website if IE is run in desktop mode, i.e. not as a Citrix XenApp published application. If IE is run as a published application certain classes required by uAInSessionHelper are not available, thus the messages.
