Description

Log file storage method, system, electronic device and storage medium Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a log file storage method, system, electronic device and storage medium. Background Art

[0002] The logging system is a critical foundational subsystem of the in-vehicle system. Unlike other system development methods, such as PC and web application development, which can be debugged online at any time, in-vehicle systems are primarily developed in the laboratory during the early stages of development. Subsequent development and operations are isolated from the development environment. For example, in scenarios like road testing and actual user driving, online debugging is impossible. This makes it difficult to locate or restore issues when they arise. In this case, system and application logs can provide critical information to assist in locating and restoring the problem. Without logs, development efficiency would be significantly reduced and even the entire development process would become difficult to carry out.

[0003] The logging system is a low-level module that end users don't directly use, and its use of system resources is relatively limited. As part of the entire vehicle computer system, the logging system consumes system resources such as CPU, memory, and storage space during operation. Furthermore, as a "non-functional module," the logging system isn't directly visible to users, but rather provides support for other system services or applications. This requires the logging module to minimize system resource usage or operate more efficiently within limited system resources.

[0004] In the prior art, a commonly used solution is to limit the number of log files and the upper limit of the size of a single file, that is, to limit the total size of the log files. When the log content exceeds the limit, the oldest log file will be overwritten, which is a circular overwriting strategy.

[0005] Patent document CN111538704A discloses a log optimization method, apparatus, device and storage medium. The log optimization method extracts the attribute features and attribute values ​​of each log in the log file set, classifies them, obtains an attribute set, constructs a tree diagram, and then selects the target attribute features. The attribute values ​​under the target attribute features are abstracted according to a preset abstract summary algorithm to obtain a key summary of the log file set, and the key summary is used to replace the log file set stored in the current system. Finally, the key summary is analyzed to improve the efficiency of abnormal diagnosis.

[0006] The above-mentioned prior art solutions have the problems of cumbersome optimization process and low optimization efficiency, which is not conducive to system development and also brings the following problems:

[0007] 1. Given log storage space, saving fewer logs for a shorter period of time is not conducive to locating and solving problems.

[0008] 2. Subsequent operations will require remote capture of vehicle logs, which will also involve network transmission, cloud storage, and automated content analysis. Inefficient log storage (redundant or invalid log content) will result in increased bandwidth usage, longer transmission times, increased error rates, larger cloud storage requirements, and lower automated analysis efficiency.

[0009] 3. Overall, the cost of R&D and operations will increase, and the cost will continue to increase over time.

[0010] 4. If the compression algorithm processes logs dynamically, it will not only occupy a lot of resources (CPU, memory, etc.), but also make it impossible to directly view the log content.

[0011] Therefore, how to provide a log file storage method to improve log optimization efficiency and optimization effect is a technical problem to be solved by those skilled in the art.

[0053] To make the objectives, technical solutions, and advantages of this application more clear, this application will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0055] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0057] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0058] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

[0059] It should be noted in particular that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0060] Referring to FIG1 , a log file storage method includes:

[0061] S101, in response to a log storage optimization request, obtaining log files contained in a log database in real time;

[0062] Specifically, in this step, when a log storage optimization request is received, the log files contained in the log database are obtained in real time;

[0063] It is understandable that the log database contains multiple log files, and log files are also continuously entering the log database. In this step, when a log storage optimization request is received, each log file and the newly entered log file are obtained in real time. The log storage optimization request can also be changed to a normally open state, so that the log database will be optimized in real time.

[0064] S102, extracting time information and log content mark information contained in the log file;

[0065] Specifically, in the step, from each acquired log file, the time information and log content tag information contained in each log file are extracted;

[0066] It can be understood that the time information contained in the log file can be understood as the time string of each log record in the log file, and the log content marking information can be understood as the log tag of each log record in the log file. From the obtained log file, the time string and log tag contained therein are extracted.

[0067] S103, optimizing the time information and the log content tag information based on the defined time optimization rules and log content tag optimization rules to shorten the representation of the time information and the content tag information;

[0068] Specifically, in this step, first, a time optimization rule and a log content mark optimization rule are defined, and then, according to the defined time optimization rule and log content mark optimization rule, the time information and the log content mark information are optimized to shorten the representation of the time information and the content mark information;

[0069] It can be understood that the defined time optimization rules and log content tag optimization rules correspond to the optimization of the time information and content tag information contained in the log file. The purpose of the optimization is to shorten the expression of the time information and content tag information, which can be understood as shortening the time string and log tag.

[0070] In some of the applications, the defined time optimization rule specifically includes optimizing the time information based on a time difference between the time information;

[0071] It can be understood that, in this application, the time difference between each time information is defined as a time optimization rule, and the corresponding time character string can be replaced by the time difference.

[0072] Furthermore, in this application, based on the defined time optimization rules, the time information is optimized to shorten the representation of the time information, specifically including determining whether the current log is the first record of the log file; when the log is not the first record of the log file, calculating the difference between the time information of the current log and the time information of the previous log; and modifying the time information of the current log based on the difference in the time information to shorten the representation of the time information;

[0073] It can be understood that in this application, it is first determined whether the current log is the first record in the log file. When the log is not the first record in the log file, it means that there is at least one previous record of this record. The time information difference of the two records is calculated, that is, the time difference of the time string. The time information of this record is modified through the time difference of the time string, that is, the time string of this record is modified to the time difference, thereby shortening the representation of the time information and optimizing the storage space. Continuing this link can save a lot of storage space.

[0074] Furthermore, in this application, when the log is the first record of the log file, the time information of the log is not optimized and the complete time information is retained; the difference between the time information of the log and the time information of the next log is calculated; and based on the difference in the time information, the time information of the next log is modified to shorten the representation of the time information;

[0075] It can be understood that when a log is the first record in a log file, the time information of the log is used as the basis, the complete time string is retained, and the time information of the next log is calculated, that is, the time difference between the time string of the next log and the time string of the log, and the time string of the next log is modified based on the time difference to shorten the expression of the time information; continuing this step can save a lot of storage space.

[0076] In some other applications, the defined log content mark optimization rule specifically includes establishing a mapping relationship value corresponding to the log content mark; optimizing the log content mark based on the mapping relationship value;

[0077] It is understandable that, in this application, a mapping relationship value corresponding to the log content mark is established, and the corresponding log content mark can be replaced according to the mapping relationship value.

[0078] Furthermore, based on the defined log content tag optimization rules, the log content tag information is optimized to shorten the expression form of the content tag information, specifically including establishing mapping relationship values ​​corresponding to the log content tags; sequentially storing the mapping relationship values ​​corresponding to the log content tags in the log database; and modifying the log content tags corresponding to the mapping relationship values ​​according to the mapping relationship values ​​to shorten the expression form of the log content tags;

[0079] It is understandable that mapping relationship values ​​corresponding to log content tags are established, each mapping relationship value is sequentially stored in the log database, and the corresponding log content tags are replaced by searching, thereby shortening the representation of the log content tags.

[0080] Furthermore, after modifying each of the log content tags corresponding to each of the mapping relationship values ​​to shorten the expression form of the log content tags based on the mapping relationship values, the method also includes, when a new log is received, determining whether there is the mapping relationship value corresponding to the log content tag of the new log; when the mapping relationship value exists, modifying the log content tag of the new log to shorten the expression form of the log content tag; when the mapping relationship value does not exist, establishing the mapping relationship value corresponding to the log content tag of the new log, and modifying the log content tag of the new log based on the established mapping relationship value to shorten the expression form of the log content tag.

[0081] It is understandable that in order to avoid newly entered logs taking up too much storage space, when a new log is received, it is necessary to determine whether there is a mapping relationship value corresponding to the log content tag of the new log. If it exists, it is modified accordingly. If it does not exist, it is created accordingly. Through the above optimization steps, storage space can be saved to the maximum extent.

[0082] S104: Update and store the optimized time information and log content mark information in the log file.

[0083] It is understandable that the above steps can improve the utilization rate of log storage space. With the same space, more valid logs can be saved, and the log storage time is correspondingly increased, which is beneficial to subsequent system development and debugging and subsequent vehicle operation.

[0084] The following describes embodiments of the log file storage method of the present invention in some applications with reference to FIG2 and FIG3 :

[0085] To illustrate the problem, refer to the following log content:

[0086] (2023-07-04 05:07:44.877852 529 2829I ActivityManager:calcYSize:unsupported or RGB color format,RGBA8888_UBWC(-1040187392)

[0091] 2023-07-04 05:09:11.980545 3112 8876I VehicleSDK_CarVehicleStateManagerProxy:getLowBeamHeight

[0092] The above log is in the standard Android log format. Each line is a record. Each record contains multiple fields separated by spaces. From left to right, they are: time, process ID, thread ID, log level, and log content (the log content starts with a colon before the log tag [also called a log tag]).

[0093] The first field is the time. For example, "2023-07-04 05:07:44.877852" means "July 4, 2023, 5:07:44:877852 hours." The actual interval between two consecutive log records is very short, typically in milliseconds or even microseconds. This field is fixed at 26 bytes.

[0094] The log tag is a name set by each log outputter, such as system service or application, to distinguish the log content output by different modules. You can see that the length of this field varies.

[0095] In the above log, you can intuitively see the time field and log tag field, which account for a considerable proportion of each log line.

[0096] In order to better understand the actual situation, we conducted a statistical analysis of the actual system logs. The following table shows the statistical results:

[0097] illustrate:

[0098] The logs are real daily development logs, totaling over 10 million lines. To a certain extent, they are generally representative.

[0099] We extracted the tags from each log line, calculated their length, and averaged them. The result was 12.2, meaning that the average tag length per line was at least 12 characters (bytes). The average tag percentage across all log files (total number of tags divided by total log size) was 0.098, approximately 10%. For a 1GB log file, tags occupy approximately 100MB.

[0100] The time stamp is of fixed length (26 bytes) and accounts for an average of 0.21 in the log file (total bytes of the time string divided by the total log size). This means that over 20% of the space is occupied by the time string. For a 1GB log file, over 200MB of space is occupied by the time string.

[0101] The average space ratio of tags and time strings (the sum of the two) is 0.308. In a 1GB log, nearly one-third of the space is occupied by these two.

[0102] The optimization scheme is described below:

[0103] As shown in Figure 2, the optimization of the time string:

[0104] The characteristics of the time string are that the time in each row is different (with a small amount of duplication) and the difference between adjacent time values ​​is very small.

[0105] Each log record does not save the complete time string. Only the time difference between the current record and the previous record is saved. The time difference is stored as an integer. You can select an integer type with different digits, such as 2 bytes, 4 bytes, or 8 bytes, depending on your needs (different system log saving frequency).

[0106] In each log file, the first line of the record must contain the complete time record. The subsequent log times can be calculated based on this.

[0107] Each file will save its own log time (the first line) to ensure that each log file can be used independently and will not be affected even if other log files are deleted, lost, or damaged.

[0108] As shown in Figure 3, the log tag is optimized:

[0109] The characteristics of log tags are: the total number of tags is relatively limited (usually only a few thousand tags in a system), and a tag may appear multiple times.

[0110] Save a tag mapping file, which contains: tag name, tag id (an integer id), and last updated time.

[0111] During logging, the tag mapping file is read into the file for efficient reading and writing. Tags are retrieved and their IDs are obtained through hashing. The hashing algorithm has a time complexity of O(1), which has little impact on operational efficiency.

[0112] Log files don't store tag names, only tag IDs. Each new log entry retrieves the corresponding tag ID from the tag mapping file. A tag ID takes up two bytes, and the average tag name is over 12 bytes long. Therefore, the 12-byte name is replaced with a two-byte ID for storage.

[0113] When restoring log content, the tag name corresponding to the id is queried through the log mapping file.

[0114] When a tag exceeds a certain length of time (you can set a fixed length, or based on the earliest time of the currently saved log), delete the unused tags to ensure that the tag mapping file does not take up too much space and only save the tag information that is valid for the current log.

[0115] Optimization effect analysis:

[0116] Time string optimization:

[0117] Only the first record in each log file stores the complete time. The total number of log files is relatively small, typically no more than 100. Compared to the millions of log lines, the space occupied by the time string in the first line of each file is negligible. The time string is ultimately optimized to an integer (time difference) to store the difference between adjacent records. This means that 2 bytes (time difference) replace 26 bytes (full time string).

[0118] Log Tag Optimization:

[0119] The total number of tags in a system is typically in the thousands (or equivalent). Compared to the millions of logs, the size of the tag mapping file is negligible. Log tags are ultimately optimized to integer IDs. This ID can be used to retrieve the corresponding tag name in the tag mapping file and restore log content. This replaces 12 bytes (tag name) with 2 bytes (tag ID).

[0120] Performance and convenience

[0121] No complex compression algorithms are used, so when processing logs in real time, there is no burden on system performance. Due to the sophisticated processing of the algorithm, there is almost no performance burden.

[0122] While improving storage efficiency, the log module can easily process and output log content for real-time viewing.

[0123] The following table summarizes the effects of log storage space optimization: Note: Optimization ratio = (original length – new length) ÷ original length

[0124] Through the optimization algorithm, time field optimization saves 92% of space. In the above example, over 200MB of space is occupied by the time field in a 1GB log file, saving 184MB of space. Log tag field optimization saves 84% ​​of space. In the above example, approximately 100MB of space is occupied by log tags, saving approximately 84MB of space. Overall, optimization can save a total of 268MB of space in a 1GB log file, a significant improvement.

[0125] For the method steps disclosed in the above embodiments, for the purpose of simple description, the method steps are expressed as a series of action combinations. However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
