Log file retrieval method and device, terminal and medium

Abstract

The invention discloses a log file retrieval method and device, a terminal and a medium. The method comprises the following steps: determining read times of a specified log file in a specified storageposition; reading the specified log file according to the preset fragment reading character number and the read times to obtain a to-be-processed log fragment; determining time information included in the log fragment; and according to the time information and a preset log retrieval time period, processing the log fragment to complete retrieval of the specified log file. The specified log file isread by taking the fragment reading character number as a unit, so that the reading frequency of the log file can be controlled, the effect of reading the specified log file in a fragmentation manneris achieved, the log reading time is shortened by controlling the data volume read each time, and the log reading efficiency is improved. Log retrieval efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a retrieval method, device, terminal and medium for log files. Background technique [0002] The log file is a record file used to record the operation content of the application program. Therefore, the problems of the application program can be tracked by monitoring the log file. For example, tracking down application problems, troubleshooting application errors, understanding application activity, etc. The monitoring log files are generally retrieved by specifying the log retrieval time, that is, positioning is performed at the specified retrieval log time, and the location until the end of the file is used as the retrieved log to complete the log retrieval. [0003] At present, three methods are mainly used for log retrieval: binary search method, tail interception method and periodic file scanning. Among them, the binary search method mainly divides the log file...

AI Technical Summary

Problems solved by technology

Therefore, this method not only needs to consume a lot of time to determine the maximum number of content, but also has the problem that the first line of data is easily truncated when intercepting the log content, resulting in the loss of key data

The periodical scan file is to periodically query the size of the log file, and to obtain the size of the latest log file content of the log file based on the difference between the two queried log files, and to search based on the size starting from the end of the log file , the main problem of this method is: because the retrieved time may not exist in the latest log content, it is necessary to retrieve the old log content again to determine the retrieval position
