Log recording method and device applied to small-capacity storage area and medium

Abstract

The invention discloses a log recording method applied to a small-capacity storage area, and the method comprises the steps: firstly setting coding data uniquely corresponding to a possible event, setting operation parameters, corresponding to each event, of the coding data, and setting a second corresponding relation indicative of the relation between the storage address of coding data and the storage address of the operation parameters; and under the condition that a target event occurs, storing the target operation parameters in the target log and the target coding data determined accordingto the first corresponding relationship into a storage region according to the second corresponding relationship. By applying the technical scheme, the running memory of the file in the prior art isomitted, the user can search the operation parameters of the corresponding event according to the second corresponding relation, the complete content of the whole target event does not need to be stored in the storage area, the occupied space of the target log is reduced, more event logs can be stored at the same time, the life cycle of each storage bit can be fully utilized, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a log recording method, device and medium applied to a small-capacity storage area. Background technique [0002] The log is an important file of the terminal device, which is usually used to record various events that occur during the operation cycle of the terminal device, such as user login, configuration parameters and hardware status, etc., so as to trace the operation status of the terminal device later or when an abnormality occurs in the terminal device If necessary, refer to the event log to find the specific problem and solution. [0003] Due to cost considerations, the current terminal devices (such as home cameras and set-top boxes) generally have a small storage area for flash storage devices (Flash). In addition to storing the necessary program codes and configuration parameters of the terminal device itself, the remaining byte space may only be a few bytes....

AI Technical Summary

Problems solved by technology

However, there are some problems in the above method: on the one hand, if the file is written into Flash, the file itself will inevitably occupy a part of the running memory as a temporary file operation space, and the event itself records a lot of information, resulting in a relatively large space occupied by each event. Large, only a few specific events can be recorded, and a large number of event logs cannot be stored for a long time

On the other hand, the flash storage area usually has a limit on the number of times of erasing and writing. After a certain number of times, the data can no longer be stored correctly. The event occupies a large space and the number of events that can be stored is very small. The flash storage area must be frequently erased to update If there are too many erasing and writing times, the life cycle of each storage bit cannot be fully utilized, which will affect the service life of Flash and further affect the user experience.
