Here are the steps you should follow to enable lab management logs at the server side.

  • Run query on configuration database (typically Tfs_Configuration)

DECLARE @Id UNIQUEIDENTIFIER = NEWID()
EXEC prc_CreateTrace @traceId = @Id , @area=’LabManagement’, @level=4

  • Start the ETW trace listener on the AT machine
  • logman -ets start TraceSession -p "Microsoft-Team Foundation Server"

  • <repro issue>
  • Stop the ETW trace listener.

logman -ets stop TraceSession

  • Dump the log files.

tracerpt TraceSession.etl

Input
----------------
File(S):
     TraceSession.etl
100.00%
Output
----------------
DumpFile:           dumpfile.xml
Summary:            summary.txt
The command completed successfully.

  • You will observe the log file (dumpfile.xml) in C:\Windows\System32 directory and that contains all the logs.

Enjoy !!
