Generate Linux Sensor Communication History

You can create a log file that provides the Linux sensor communication history.

Procedure

• ♦ Running inside a terminal as root and sending the SIGUSR2 signal (via su), issue this command:

  kill -s12 $(pidof cbdaemon)

  The log is located at /var/tmp/cb/sensor_comms.log. Each transaction has a HRESULT, which can be one of the following:

  Table 1. HRESULT

  Facility Number	Description	Error Code Value
  204	OS level errors	Maps to errno
  25	HTTP ererors	HTTP error code
  200	Curl errors	See http://curl.haxx.se/libcurl/c/libcurl-errors.html.
  201	Curl form errors

  Note: For sensor version 6.2+, the log location is /var/opt/carbonblack/response/diagnostics. In some sensor versions you might need to run a mkdir /var/opt/carbonblack/response/diagnostics command first.
