Log information management method and system

Abstract

The method divides log information management system into log request process module and log information process module. Log detection process of the method includes (1) the log request process module constructs and outputs log detection request to the log information process module; (2) after detecting the log detection request, the log information process module detects stored state of log information in log information base, determines whether the detected stored state of log information exceeds prearranged configured threshold of log stored state; if yes, deleting log information with attribute being as unimportant in log information base; otherwise, ending current process. The invention realizes detection of log information, deletes unimportant log information automatically.

Description

technical field [0001] The invention relates to a log information processing technology of a computer system, in particular to a log information management method and system. Background technique [0002] At present, almost all computer systems need to save log information regularly or in real time. The log information records the situation of each operation of the computer system, including: saving time, equipment, commands and command processing status, etc., so that according to the log information can be Diagnose the system failures that occur and restore the system to operation in time. Among them, there are basically two management methods of log information: file system-based and database system-based. [0003] The file system management method of the log information is a relatively traditional management mechanism. The main features of this mechanism are: 1. The log information is stored in the external memory in the form of a file for a long time; 2. When the appli...

Problems solved by technology

However, when this mechanism is applied to a large-scale computer system, the following problems will occur: 1. The log information is stored in files, and the information is not structured, and each file is isolated, so it cannot reflect the connection between the log information; 2. The storage of log information depends on the logical relationship between applications. Usually, one or several applications share a log information file; 3. The representation of log information depends on the application, which is not easy to expand and has poor independence. The same log Information may be stored in multiple log files with different values, therefore, the data has high redundancy and poor consistency

[0005] However, the existing log information management system treats all log information indiscriminately, and a large amount of unimportant log information is often stored in the log information database, which wastes a lot of storage space, and even makes it impossible to save important log information.

In this way, when the system fails, the log information saved in the database often cannot meet the needs of problem analysis, which greatly reduces the utilization value of the log information.

In addition, due to the limited storage space of the database, users must regularly clear the log information through configuration commands, which is not only inconvenient for users to use, but also unable to clear unimportant log information in real time and effectively

[0006] To sum up, although the current log information database management mechanism can realize the sharing of log information, with the continuous expansion of computer systems, the processing capacity of log information will increase greatly. How to make full use of database storage resources to effectively save important logs Information has become an urgent problem to be solved in the current log information management technology
