Problems solved by technology

In enterprise-level Java development, sometimes we encounter the following problems: memory overflow, insufficient memory, memory leak, thread deadlock, lock contention, Java process consumes too much CPU, etc.
The method of using memory usage to characterize the level of JVM load does not reflect the real load of JVM well.
When the memory usage rate is high, it is likely that the java objects in the JVM can be effectively recycled by the GC. In this case, the real situation of the JVM load is not high. If the memory usage rate is directly used to represent it, it will be misjudged as high Load, and then take a series of unnecessary response measures, affecting the user experience, for example, frequently sending risk warnings, frequently restricting user requests, etc.
When the memory usage rate is not very high, it is possible that the active threads in the JVM are rapidly creating java objects. According to the life cycle of java objects, such objects are generally difficult to be effectively recycled by the GC in a short period of time. As a result, the JVM quickly enters an overloaded state. In this case, the real situation of the JVM load is very high. If it is directly represented by the memory usage rate, it will be misjudged as a low-to-medium load, so it misses a good opportunity to take effective operation and maintenance measures. affect the stable operation of the system
[0004] Therefore, the current existing technology uses the memory usage rate to analyze the JVM load, which is prone to the problem of false alarm

Abstract

The invention discloses an exception processing method and device based on garbage collection logs, wherein the method includes: generating a GC log according to a preset generation parameter of a GC log and storing it in a preset path; reading in the preset path In the GC log, the data to be analyzed is extracted from the GC log; wherein, the data to be analyzed is used for abnormal analysis; the data to be analyzed is input into a preset recognition model for identification, and an abnormal analysis result is obtained; JVM parameters for tuning. The method and device of the present invention can comprehensively utilize all the data to be analyzed, so as to avoid only considering the memory usage in manual identification, and fail to identify the abnormality of high JVM load. Therefore, the method of this embodiment improves the accuracy and efficiency of anomaly identification.

Description

technical field [0001] The present invention relates to the technical field of computer software, and in particular, to a method and device for processing exceptions based on garbage collection logs. Background technique [0002] In the daily software development process, it is inevitable to handle exceptions. In enterprise-level Java development, sometimes we encounter the following problems: memory overflow, insufficient memory, memory leak, thread deadlock, lock contention, Java process consumes too much CPU, etc. The memory managed by the JVM (Java Virtual Machine, Java Virtual Machine) roughly includes three different types of memory areas: Permanent Generation space (permanent storage area), Heap space (heap area), and Java Stacks (Java stack). The permanent storage area mainly stores the information of Class (class) and Meta. When the Class is loaded for the first time, it is put into the PermGen space area. The content that the Class needs to store mainly includes m...
