Problems solved by technology

However, the current solution for monitoring multi-core CPU usage is to monitor the average value of multi-core CPU usage, which cannot reflect the real usage of each core in a multi-core CPU.
When an infinite loop occurs in a core of a multi-core CPU, it cannot be detected in time
For example, in an 8-core CPU, if the usage rate of one of the cores has reached 100%, but the average usage rate of the 8-core CPU is only 12.5%, therefore, it is impossible to know the situation of the infinite loop in time

Abstract

The invention discloses a method and device for detecting a multi-core CPU. The device comprises a monitoring module for monitoring usage rate of each core of the multi-core CPU and running time of each thread in the core; a detection module for detecting the core and thread in fault in the multi-core CPU according to the usage rate of each core of the multi-core CPU and running time of each thread in the core. Through the adoption of the method disclosed by the invention, each core in the multi-core CPU can be independently monitored so as to reflect the real usage condition of each core. In addition, the method comprises the steps of periodically scanning a thread stack of a server and analyzing a thread stack log to detect whether the thread with long running time exists, and then judging the running state of the multi-core CPU in combination with the usage condition of each core. Through the adoption of the method, the fault similar to endless loop in the multi-core CPU can be immediately and fast discovered, thereby immediately notifying a worker to solve the fault problem.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for detecting a multi-core CPU (Central Processing Unit, central processing unit). Background technique [0002] With the continuous development of computer technology, the number of cores used in the CPU continues to increase, and more and more multi-core CPUs are used in servers. However, the current solution for monitoring multi-core CPU usage is to monitor the average value of multi-core CPU usage, which cannot reflect the real usage of each core in the multi-core CPU. When an infinite loop occurs in a core of a multi-core CPU, it cannot be detected in time. For example, in an 8-core CPU, if the usage rate of one of the cores has reached 100%, but the average usage rate of the 8-core CPU is only 12.5%, therefore, the situation of the infinite loop cannot be known in time. Contents of the invention [0003] The main purpose of the present inve...
