Embodiment Construction

[0021] The CPU stress test method based on the shell script described in the present invention can run under the MCS system based on the linux kernel of the simplified version, adopt the bash shell script to carry out the language design, and use the core plug-in of MCS utilization analysis tool lssystemstats to check the CPU usage By running shell scripts, create mirrored volumes, compressed volumes, and self-thinning volumes, and perform operations such as volume mirroring, volume copying, and snapshots on all existing volumes.

[0022] The method includes the following steps:

[0023] 1. Determine the number and ID of hard disks, and execute the script to create MDISK with RAID5 type for every 3 hard disks;

[0024] 2. Get 1 / 2Pool capacity;

[0025] 3. Execute the scripts for creating self-thinning volumes, compressed volumes, and mirrored volumes of 200G per Volume according to the Pool capacity;

[0026] 4. Execute the script file for snapshotting, backing up and clonin...

Abstract

The invention discloses a CPU stress test method based on a shell script. Through the circular shell script design, the creation of different MDISKs, volumes, including self-streamlined volumes, compressed volumes, mirror volumes and so on, and through a combination of several volume operations, the working pressure of a CPU can be improved. The stress test method provided by the invention can notonly test the CPU usage rate of a storage system, but can also quickly improve the CPU occupancy rate of an MCS system in performance statistics for a performance statistical analysis tool of an MCSself body, and a feasible method for realizing the CPU pressure of the MCS system in the actual testing process is provided.

Description

technical field [0001] The invention relates to the field of server testing, in particular to a shell script-based CPU stress testing method. Background technique [0002] The CPU is one of the most core components in a computer. When the CPU has performance problems, it will cause the entire computer system to run unstable. [0003] The MCS system is a streamlined linux based on the Linux kernel. In order to ensure the stability and reliability of the MCS system, most common commands running on the Linux system cannot run under the MCS system, and MCS has privatized the relevant commands. In addition, a kernel plug-in that can count CPU usage in real time is designed under the MCS system. The CPU usage of performance statistics under the GUI interface depends on this kernel plug-in under MCS. Therefore, simply increasing the CPU usage of the Linux system cannot trigger MCS. The CPU usage of the system increases or exceeds the corresponding threshold. To increase the CPU ...
