Abstract
The invention discloses a method for automatically testing an lmbench memory under Linux, which relates to the technical field of server pressure testing, and utilizes a self-contained Bash language and an lmbench tool under a Linux operating system to automatically test the lmbench memory, wherein the automatic testing process comprises the following steps: compiling and installing test software, executing a pressure test, recording a test result and uploading the test result to a designated FTP server. The method realizes the automation of the whole process of testing the memory bandwidth of the lmbench tool, improves the testing efficiency and ensures the testing quality.
Description
Technical field
The present invention relates to server stress technical field of measurement and test, specifically a kind of method of lmbench internal memory automatic test under Linux.
Background technology
It is known that for meeting the diversified demand of different user, it is ensured that various applied environments stable, reliable, stability is had high requirement by key business server.No matter a server is at development or subsequent product maintenance phase, is required for product is carried out comprehensive system stress test, so that it is guaranteed that the stability of this product.Internal memory is as server vitals, and whether it stablizes direct relation server performance and stability.
Linux is the operating system based on the multi-user of POSIX and UNIX, multitask, support multithreading and multi-CPU.It can run main unix tool software, application program and procotol, supports 32 and 64 hardware.Linux also exists many different linux versions, but they all employ linux kernel, and custom Linux describes whole based on linux kernel, and uses the operating system of the various instrument of GNU engineering and data base.
Bash (GNUBourne-AgainShell) is the acquiescence Shell of many Linux release, and a ShellScript generally can use on a variety of Shell.Bash is most of linux system and the shell of MacOSX acquiescence, and it can run on the operating system of most of class Unix style.The command syntax of bash is the superset of Bourneshell command syntax.Namely the Bourneshell script of substantial amounts is scarcely modified can perform in bash, only used Bourne special variable or employ Bourne built-in command script just need amendment.As an interactively shell, press TAB key and get final product the program name of auto-complete part input, filename, variable name etc..
Lmbench is a set of simple and easy transplantable, and meeting ANSI/C standard is the UNIX/POSIX miniature evaluation tool formulated.In general, it weighs two key features: response time and bandwidth.Lmbench is intended to the basic cost making system developer understand key operation in depth.Lmbench has following principal character: a) test for portability of operating system, b) self-adaptative adjustment, c) calculates database result, d) memory latency result of calculation, e) context switch result of calculation, f) regression test etc..The installation installing and using Lmbench is relatively simple, downloads compressed package Lmbench.tar.gz to its official website and is decompressed, and enters the directory command line unit after decompression and enter makeresults and can start compiler test.
In order to improve server memory automatic test effect, the present invention proposes a kind of lmbench internal memory automated testing method based on Bash under linux.
Summary of the invention
The present invention is directed to current needs and the weak point of prior art development, it is provided that a kind of method of lmbench internal memory automatic test under Linux.
The method of lmbench internal memory automatic test under a kind of Linux of the present invention, the technical scheme solving the employing of above-mentioned technical problem is as follows: the method for lmbench internal memory automatic test under described Linux, utilize and under (SuSE) Linux OS, carry Bash language and lmbench instrument, carry out lmbench internal memory automatic test, automatic test course includes: compiling and installation test software, perform stress test, record test result and test result is uploaded to appointment ftp server.
Preferably, described compiling and installation test software refer to, carry bash script by writing (SuSE) Linux OS, server memory lmbench instrument are compiled automatically and installs.
Preferably, the method for lmbench internal memory automatic test under described Linux, implement step as follows:
1) lmbench instrument is replicated to linux system；
2) automatic test script file is write；
3) give automatic test script file and can perform authority；
4) under linux system terminal, automatic test script file is run.
Under a kind of Linux of the present invention, the method for lmbench internal memory automatic test compared with prior art has the beneficial effect that the memory bandwidth that the method can be widely used in all types of servers under linux system and stability automatic test, the use of this method enormously simplify the operating process of memory bandwidth and stability test, easily realize being installed to stress test from lmbench testing tool to perform, arrive test result record again, and test result such as uploads at the automatization of overall process；Realize the automatization of lmbench instrument memory bandwidth test overall process, improve testing efficiency, it is ensured that test quality, save the testing time, reduce human input, Improving The Quality of Products, save cost for company.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, the method for lmbench internal memory automatic test under a kind of Linux of the present invention is further described.
The present invention provides a kind of method of lmbench internal memory automatic test under Linux, utilize and under (SuSE) Linux OS, carry Bash language and lmbench instrument, carry out lmbench internal memory automatic test, and record test result, upload test result to specifying ftp server.This method can be widely used for memory bandwidth and the stability automatic test of all types of servers under linux system, and the use of this method enormously simplify the operating process of memory bandwidth and stability test.
Embodiment:
The method of lmbench internal memory automatic test under a kind of Linux described in the present embodiment, utilize and under (SuSE) Linux OS, carry Bash language and lmbench instrument, realize lmbench and carry out internal memory automatic test, automatic test course includes: compiling and installation test software, perform stress test, record test result and test result is uploaded ftp server.
The method of lmbench internal memory automatic test under Linux described in the present embodiment, described compiling and installation test software refer to, carry bash script by writing (SuSE) Linux OS, server memory lmbench instrument are compiled automatically and installs.Meanwhile, then carry out automatic pressure Force meansurement, and after test terminates, record test result, and upload test result to specifying ftp server.Perform thus realizing being installed to stress test from testing tool, then to test result record, and test result such as uploads at the automatization of overall process, significantly improves testing efficiency, it is ensured that test quality.
The method of lmbench internal memory automatic test under Linux described in the present embodiment, implements step as follows:
1) lmbench instrument is replicated to linux system；
