Solution
Logging can be enabled with following server-side registry settings:
[HKEY_LOCAL_MACHINE\SOFTWARE\Motive\M-Files\<version>\Server\MFIndexer\Logging]
"Enabled"=dword:00000001
"EnableVerboseLogging"=dword:00000002
"LogDir"="%TEMP%\MFilesLogs"
"FlushIntervalInSeconds"=dword:0000000a
"LogCategories"=dword:ffffffff
[HKEY_LOCAL_MACHINE\SOFTWARE\Motive\M-Files\<version>\Server\MFIndexingManager\Logging]
"Enabled"=dword:00000001
"EnableVerboseLogging"=dword:00000002
"LogDir"="%TEMP%\MFilesLogs"
"FlushIntervalInSeconds"=dword:0000000a
"LogCategories"=dword:ffffffff
Those keys are in the registry by default, to enable the logging make sure Enabled is set to 1 and EnableVerboseLogging is 2, no need to restart M-Files Server service.
By default the location of log files is %TEMP%\MFilesLogs. (In test environment: C:\Windows\Temp\MFilesLogs.)
After you have enabled the logs, you should immediately see following kind of files in the log directory:
