How to enable verbose user and kernel-mode logging locally via command prompt for EDR Windows sensors.


  • EDR Sensor: 5.x and higher
  • Microsoft Windows: All Supported Versions


  1. Back up the registry prior to enabling logging
  2. Locally enable verbose logging:
    • Open a command prompt as administrator
    • Enter the following two commands:
      • reg add HKLM\Software\CarbonBlack\config /v DebugLevel /t REG_DWORD /d 7
        reg add HKLM\Software\CarbonBlack\config /v KernelDebugLevel /t REG_DWORD /d 7
    • The registry setting will not take affect until the user-mode sensor service is requested to update:
      • sc control carbonblack 203
  3. Reproduce the issue
  4. Collect logs.
  5. Disable debug logging from the command prompt
    • reg delete HKLM\Software\CarbonBlack\config /v DebugLevel /f
      reg delete HKLM\Software\CarbonBlack\config /v KernelDebugLevel /f
      sc control carbonblack 203
  6. If necessary, upload the diagnostics to the tech support case.
