There is design change in the way logon timing data is collected for a Windows session from Pre 8.4 (Horizon 8 2106 and Earlier) to 8.4 onwards ( Horizon 8 2111 and Later). This article provides information about the logon timing data reporting and changes.
Pre 8.4 (Horizon 8 2106 and Earlier) 8.4 onwards ( Horizon 8 2111 and Later) Source of information Registers logon events from sysntfy.dll ETW events also subscribed for some events like user and group policy. Uses ETW providers like Microsoft-Windows-Winlogon, Microsoft-Windows-User Profiles Service, Microsoft-Windows-GroupPolicy,Microsoft-Windows-Winlogon and Microsoft-Windows-Shell-Core etc. Loglines: In VMLM session log file, look for following log line for total logon time: 2023-05-30T14:15:48.582 INFO (1020-25d8) [LogonMonitor::LogSummary] Logon Time: 38.80 second Here we need to check for two log lines and then add the timings to get total logon time in VMLM session log file: 2023-05-30T15:54:27.609 INFO (09dc-2838-1) [9602] [Microsoft-Windows-Shell-Core] Login 2023-05-30T15:53:48:070 - 2023-05-30T15:53:58:690 (dur 10.62 seconds) 2023-05-30T15:54:27.609 INFO (09dc-2838-1) [9602] [Microsoft-Windows-Shell-Core] Shell Load Time: 28.31 seconds Now we need to add both timings, in this case: 10.62 +28.31 = 38.93 seconds. In this example , the total logon time is the time from user authentication to successful launch of shell(explorer). Some more information about design change : With Horizon 8 2106 and Earlier, there was a requirement to enable the VMLM(VMware Horizon View Logon Monitor) service to get the logon timings.With Horizon 8 2111 and Later, this dependency is no longer there, and the Horizon Agent takes care of logon timing data collection. However, if the VMLM service is enabled then the logon timing data is published there in VMLM session specific file. Along with that logon timing data is always logged in vdm debug*.txt file.
