Description

The Start-SbecNtKernelLogSession cmdlet starts a real-time NT Kernel Logger trace session with forwarding of the events to the Collector. The name of the session is fixed as NT Kernel Logger and the GUID is fixed as {9e814aad-3204-11d2-9a82-006008a86939}.

Optional Parameters

-BufferSize

Specifies the buffer size for the session, in kilobytes. This is the size of one buffer, with the count of these buffers set by the MinimumBufferCount and MaximumBufferCount parameters.

Type:UInt32
Position:1
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-ClockType

Specifies the type of clock used for the events collected by this session: The acceptable values for this parameter are:

  • Default.
  • QueryPerformanceCounter. The high-resolution (period of 100 nanoseconds) clock that is typically used for performance measurement.
  • SystemTime. The lower-resolution system time similar to FILETIME (period of 10 milliseconds). This value is most typical for the data collection through SBEC.
  • CpuCycleCounter. The highest-resolution, with the frequency of the CPU, but may be unreliable depending on the CPU model and the thermal and power modes.
Type:ClientContext
Parameter Sets:Default, QueryPerformanceCounter, SystemTime, CpuCycleCounter
Position:0
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-FlushSeconds

Specifies the timeout in seconds for the session buffers to get automatically flushed. You can disable the flushing of buffers on timeout by setting this parameter to 0, then the buffers will be written only when full or on an explicit flush.

Type:UInt32
Aliases:FlushTimer
Position:4
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-KernelEnableFlags

Specifies flags for the NT Kernel Logger that enable the kernel events. For the setup and boot monitoring, the only reasonable flag is Process. This enumeration type is defined in $PsHome\Modules\BootEventCollector\SbecTraceHelpers.psm1. The acceptable values for this parameter are:

  • Process
  • Thread
  • ImageLoad
  • ProcessCounters
  • ContextSwitch
  • Dpc
  • Interrupt
  • SystemCall
  • DiskIO
  • DiskFileIO
  • DiskIOInit
  • Dispatcher
  • MemoryPageFaults
  • MemoryHardFaults
  • VirtualAlloc
  • NetworkTCPIP
  • Registry
  • Alpc
  • SplitIO
  • Driver
  • FileIO
  • FileIOInit
  • Profile
Type:EventTraceFlag
Parameter Sets:None, Process, Thread, ImageLoad, ProcessCounters, ContextSwitch, Dpc, Interrupt, SystemCall, DiskIO, DiskFileIO, DiskIOInit, Dispatcher, MemoryPageFaults, MemoryHardFaults, VirtualAlloc, NetworkTCPIP, Registry, Alpc, SplitIO, Driver, FileIO, FileIOInit, Profile
Position:5
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-MaximumBufferCount

Specifies the maximum number of buffers to allocate for this session.

Type:UInt32
Aliases:MaximumBuffers, maxbuf
Position:3
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-MinimumBufferCount

Specifies the minimum number of buffers to allocate for this session.

Type:UInt32
Aliases:MinimumBuffers, minbuf
Position:2
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False

Inputs

None.
