Problems solved by technology

[0005] In the existing technology, the log file printed and output by the server background program contains a large number of formatted row information with repeated fields, which makes the printing of the log file occupy a large amount of IO resources of the system, which affects the operating efficiency of the program. At the same time, the printed The log files occupy a large amount of storage space. In order to reduce the disk storage space, the log files are usually compressed into binary files on a regular basis, and then restored and decompressed when they need to be queried in the future. Large problems and the problem of a large amount of system IO resources occupied when printing log files

Abstract

The invention relates to the technical field of computers, and particularly discloses a program compression log file output method and device. The method includes the steps: acquiring a plurality of log data generated within specified time; taking the time difference between a date field and a starting time field defined for a log file as a compressed date field expression for each log datum, and taking specified numbers allocated by preset field format strings as a compressed field name expression; outputting the log data compressed within the specified time to the log file. Each log datum comprises a plurality of data items and the date field corresponding to the generation time. By replacing format line information with a large number of repeating fields in the log data, the log data are compressed in real time, IO resources occupied by programs outputting the log file are decreased, storage space occupied by a large number of log files is saved, and the running efficiency of the programs is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of computers, and specifically discloses a program compression log file output method and device. [0003] 【Background technique】 [0004] With the development of the Internet, data has become a strategic resource, and the fields and frequency of electronic logs are constantly increasing. Electronic log files can record necessary and valuable information for servers, workstations, firewalls, and application software. Therefore, The recording, collection and storage of access logs generated on the Internet become the key, especially for log storage. Since the storage space occupied by uncompressed original logs is too large, the original logs must be compressed to achieve long-term preservation. [0005] In the existing technology, the log file printed and output by the server background program contains a large number of formatted row information with repeated fields, which makes the printing of the ...
