Description

Log information extraction device and method in combat system system}

The present invention relates to an apparatus and method for extracting log information from a combat system system, and in particular, log information of a Linux application program executed in a combat system is automatically recorded/collected and stored, and the recording/collected result can be checked by an operator. It relates to a log information extraction device and method for displaying log information in a combat system system.

In general, an operating system is system software that provides a hardware abstraction platform and common system services to manage system hardware and execute application software.

The operating system may create a process by executing application software and may terminate it. And the operating system can suspend the running process and resume it. In addition, the operating system can manage memory and control input/output devices.

Operating systems can be classified into several types depending on the type of computer system. For example, the operating system may be classified into a desktop operating system, a mobile operating system, a server operating system, and an embedded operating system. Each operating system can manage files by implementing its own file system.

Since each operating system has a different method of managing or controlling processes, memory, and input/output devices, it is possible to distribute application software built differently for each operating system. Therefore, application software built and distributed to run on one operating system cannot be run on another operating system.

To solve this problem, after running virtual machine software in one operating system, installing and running another operating system on the virtual machine, and then installing application software built and distributed for the other operating system, You can run built and distributed application software.

The Windows operating system provides WSL2 (Windows Subsystem for Linux 2), which enables running the Linux operating system using virtualization technology. Accordingly, application software built and distributed for the Linux operating system can be executed on the Windows operating system.

On the other hand, an embedded system refers to a computer system specialized for a specific environment, not an environment that executes a specific application program or is used for general purposes. Mobile phones, home game consoles, and digital TVs are representative embedded systems, and as the required functions of embedded system devices become increasingly complex, embedded systems that traditionally operate without operating systems are evolving into embedded systems equipped with modern operating systems.

Unlike personal computers, embedded systems are composed of various processors, memories, and peripherals depending on the purpose of use. In addition, to configure the system by limiting functions to specific uses, most of them use a central processing unit with a small storage capacity and a low processing speed.

As such, many attempts have been made to select Linux as an operating system (OS) used in an embedded system that can have various configurations.

Linux is a computer basic operating system that made Unix, an operating system that only operated on large models, to operate on small PCs. Linux has the advantage that program source codes are open, so programmers can add specific functions as desired, and porting to any platform is possible. In particular, Linux has the advantage of being able to lower the unit cost of the product because the program source code is open to the public for free.

On the other hand, due to the limited environment of the embedded system, a development environment capable of selecting and installing only necessary applications and kernel functions to be installed in the system is required. The kernel is the most important core of a computer operating system and provides several basic services to all other parts of the operating system.

In general, the kernel includes an interrupt handler that handles all requests that competitively request kernel services, such as completed input/output operations, and a scheduler that determines which programs, in what order, share the kernel's processing time, and when the schedule is finished. In fact, it includes a supervisor that grants the right to use the computer to each process.

The kernel also has a memory manager that manages the operating system's address space in memory or storage and distributes them evenly among all peripherals and other users who use the kernel's services.

Services from the kernel are requested from other parts of the operating system or through a series of programmatic interfaces known as system calls. Since the code to maintain the kernel is used continuously, the kernel is usually loaded into a protected memory area so that it cannot be overwritten and corrupted by the rest of the operating system that is not used very often.

In the case of such a Linux application program, it is applied to various combat systems, and in order to check the log of a Linux application program in an existing combat system, after individual access through ssh (Secure Shell), a specific log file is opened through the “” command. confirmed about. Here, ssh is an Internet protocol used to connect to a remote host computer.
