Method and apparatus for outputting early warning information

Abstract

The present invention provides a method and an apparatus for outputting early warning information. Memory using data during the running of a system can be collected and analyzed in real time and then early warning information can be output, so that not only, before the memory of the system goes wrong, predetermination can be performed to output the early warning information, but also the waste of labor can be avoided, and thus the decision speed and accuracy in fields such as security monitoring are improved. The method for outputting the early warning information provided by the present invention comprises: for every set cycle, receiving running data, which is acquired by a client, of an application system of a current monitor; calculating memory information in the running data to obtain the memory occupancy ratio of the application system corresponding to the data time; acquiring historical running data of the application system according to a system identity in the running data; and comparing the memory occupancy ratio with the historical running data, then updating the historical data according to a comparison result, and outputting the early warning information according to a preset early warning condition and the updated historical data.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for outputting early warning information. Background technique [0002] Java Virtual Machine Java Virtual Machine is a specification for computing equipment. It is a fictitious computer that is realized by simulating various computer functions on an actual computer. The Java virtual machine shields the information related to the specific operating system platform, so that the Java program can run without modification on various platforms only by generating the object code that runs on the Java virtual machine. Basically, the Java virtual machine can be regarded as a special operating system specially designed for Java. Its job is to manage the runtime environment for running Java applications. [0003] Java virtual machine memory, as an important operating resource, plays a key role in the stable and efficient operation of the Java system. The Java virtual ...

AI Technical Summary

Problems solved by technology

[0006] 1) Similar to tools like Javamelody, its entry is just a filter (filter), and long-term use will bring performance problems to running Java applications;

[0007] 2) If there are many Java application servers maintained, the use of Java virtual machine monitoring tools will lack unified management. In addition, factors such as security cannot be ruled out

[0008] 3) Most of the existing Java virtual machine memory monitoring tools are based on remote operations. The principle is to form a snapshot file on the target server, because the Java virtual machine memory installed on the general server is relatively large, and the generated snapshot files are also relatively large. Relatively large, the usual method is to copy the corresponding snapshot file and analyze it through other visual tools, which is very inconvenient to use and does not have the function of early warning and alarm

[0009] 4) Even with the visual monitoring tool Jconsole that comes with JDK, there will be a time delay when viewing the relevant data of the memory usage of the Java virtual machine, and it is unrealistic to manually observe the memory operation of the Java virtual machine 7*24 hours a day of

[0010] 5) It is basically impossible for existing Java virtual machine memory monitoring tools to make predictions and early warnings before problems occur in the Java virtual machine memory.
