This is the
Process ID (PID) for the process that caused the SysLog message. This name may not be the name of the program sending the SysLog message to the server. This value is used only if
TIdSysLogMsgPart.PIDAvailable property is set to true. The value is obtained by parsing the
TIdSysLogMsgPart.Text text property and setting this property will update the
TIdSysLogMsgPart.Text property.
