Problems solved by technology

When looking for a log record whose field value is a specific value, it is necessary to traverse each log record to determine whether the value of the field is a specific value. Obviously, this traversal search method is very inefficient, especially when there are many logs. consumes more time and resources

Abstract

The invention provides a method and a device for building log indexes. The method for building the log indexes includes determining at least one necessary field combination in log files according to preset field combination rules; executing operation for each log record in the log files, to be more specific, acquiring values of fields in the log records, splicing the values of the fields to obtainvalues of the necessary field combinations and acquiring offset locations of the log records in the log files; creating index records for the different values of each field combination; writing the index records of the same field combination into a single index file of the corresponding log file. The index files need to be created for the necessary field combinations determined according to the preset field combination rules. The index records further comprise offset locations of the log records corresponding to the different values. According to the scheme, the method and the device have theadvantage that the log searching efficiency can be effectively improved by the method and the device.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a log index construction method and device. Background technique [0002] In a computer, events that occur during the operation of the operating system or other software are usually recorded in a log, and the log can provide information such as daily maintenance of the operation of the system and diagnosis of software problems. When recording logs, a preset log format is usually used, that is, one or more fields to be recorded are preset, and the value of each preset field may be different for different events. The log recorded for an event is composed of the values ​​of all the preset fields of the event. For example, if the fields of a log recording a certain software operation are set to "time" and "operation", each time the software performs an operation, a log including the time value and operation value will be generated, and the user needs to check when a cert...
