Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the application provides a device log storage method. The execution subject of the device log storage method includes, but is not limited to, at least one of electronic devices that can be configured to execute the method provided by the embodiments of the present application, such as a server, a terminal, and the like. In other words, the device log storage method may be performed by software or hardware installed in the terminal device or the server device, and the software may be a blockchain platform. The server includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, and the like.
Fig. 1 is a schematic flowchart of a device log storage method according to an embodiment of the present invention. In this embodiment, the device log storage method includes:
and S1, acquiring real-time log information of the equipment side.
In the embodiment of the present invention, the device side refers to an embedded electronic device having a certain specific function to meet a certain requirement of a user, for example, a smart watch, a camera device, and the like.
In the embodiment of the invention, the log information is a recording file or a file set for recording the system operation event, and the running state of the equipment terminal and the like can be recorded through the log information.
S2, extracting all the character string information in the real-time log information, and identifying the type of the real-time log information according to a static character string library constructed by the character string information and the equipment information of the equipment terminal.
In the embodiment of the present invention, the character string information refers to a character string text describing an operating state of the device side, for example, the character string information is "Buffer 0x12345678length 234data a, B", where the character string Buffer represents a cache, the character string length represents a data length, and the character string data represents data.
The static character string library comprises character string information commonly used by the equipment terminal in some historical logs and character string information added by a user according to an actual application scene.
Specifically, before the static string library constructed according to the string information and the device information of the device side identifies the type of the real-time log information, the method further includes:
extracting the unique equipment identifier of the equipment terminal;
and extracting historical static character strings from the historical log information according to the unique equipment identifier, and summarizing the historical static character strings and preset extension character strings to obtain a static character string library.
In the embodiment of the present invention, the device unique identifier may be extracted from device information of a device side, where the device information includes the device unique identifier, a firmware version number of the device, log collection state information, and the like. The device unique identifier may be uuid, that is, a device may be uniquely identified by the device unique identifier, and the device unique identifiers of different devices are different. The history log information records log information of different devices.
Extracting the historical static character string from the historical log information according to the unique identifier of the equipment refers to extracting the static character string which has a corresponding relation with the unique identifier of the equipment from the historical log information.
In particular, a static string means that the string text is fixed and invariant, such as the string text "hello, world".
Or some fixed parts in the character string may be changed, but after the changed parts are described in a parameterization manner, the parameters themselves may completely describe the changed contents, for example, the character string is ' ″ data length% d ', data _ length ', where% d is a placeholder and data _ length is a parameter character string, and the display contents of the% d part are replaced according to the actual result of the runtime.
The extension string includes a reference statement, reference placeholder, etc., e.g., "% d" placeholder to reference other strings
In the embodiment of the invention, more accurate static character string library can be constructed by utilizing the historical log information and the preset extension character string.
For example, historical static strings include "hello, world", "data length", etc., and extension strings include placeholders such as "% d".
Specifically, the identifying the type of the real-time log information according to the static character string library constructed according to the character string information and the device information of the device side includes:
calculating the similarity between each piece of character string information and the character strings in the static character string library;
if the similarity between all the character string information and the character strings in the static character string library is greater than or equal to a preset similarity threshold, determining that the log information is of a static type;
and if the similarity between any character string information and the character strings in the static character string library is smaller than or equal to the similarity threshold, determining that the log information is of a dynamic type.
In the embodiment of the present invention, the static type indicates that all the character string information of the log is static character strings, and the dynamic type indicates that all the character string information is not static character strings, that is, the content of a character string cannot be determined completely or partially before actual operation, such as a character string returned from a network interface, or other character strings are referred to in the character string (for example, a character string referred to by using the% s placeholder of c language printf).
For example, the dynamic type log information is: < "hello,% s", name >, where name is the other string referenced.
In this embodiment of the present invention, the calculating the similarity between each piece of the character string information and the character strings in the static character string library includes:
and sequentially calculating the similarity between the character string information and the character strings in the static character string library by using the following similarity calculation formula:
wherein j (A, B) is the similarity, A is the character string information, and B is the character string in the static character string library.
In an optional embodiment of the present invention, the preset similarity threshold may be 100%. For example, string information < "hello,% s", name >, where name is the other string referenced. The segmented character string field comprises "% s", which represents a character string placeholder and is used for referring to other fields, and the character string field cannot be found in a static character string library, and then the character string information is determined to be in a dynamic type.
And S3, if the real-time log information is in a static type, performing fixed format coding on all character string information in the real-time log information to obtain a static coding log.
In the embodiment of the invention, because all the static type log information are static character strings, namely the character strings are fixed and unchangeable, the static type log information can be encoded according to a fixed format to obtain the static encoding log with smaller data size.
Specifically, the encoding all the character string information in the real-time log information in a fixed format to obtain a static encoded log includes:
generating a static identifier of the real-time log information;
extracting character string parameters corresponding to each static character string contained in the real-time log information;
and summarizing the static identification and the extracted character string parameters to obtain the static encoding log.
In this embodiment of the present invention, the log information of the static type may be numbered by sequentially increasing 1 according to the minimum available numerical value, for example, the static identifiers are sequentially 1, 2, 3, and ….
In an alternative embodiment of the present invention, five fixed fields may be used for encoding: string ID, parameter 1, parameter 2, parameter 3, parameter 4. For example, for the static type log information "Buffer 0x12345678length 123content 66, 65", the encoded static encoding log is "1, 0x12345678,123,65, 66", where the first bit indicates that the static string ID is 1, and the second bit to the fourth bit are, in turn, parameter 1 to parameter 4 corresponding to the static string.
When the information type of the log information is a static type, because the static type log information usually contains fixed and unchangeable character string content, if the description information (i.e., the static character string) and the key parameter value (and the parameter corresponding to the static character string) are stored and transmitted together, this will also bring great pressure to the storage space and the network bandwidth of the device, therefore, in this embodiment, by performing fixed format encoding on the static type log, the purpose of data compression can be achieved, and the excessive occupation of the storage space and the network bandwidth is reduced.
And S4, if the real-time log information is of a dynamic type, performing dynamic format coding on all character string information in the real-time log information to obtain a dynamic coding log.
In the embodiment of the present invention, since the dynamic type string information is not all static strings, that is, the strings are not fixed, encoding cannot be performed according to a fixed format.
Specifically, the dynamic format encoding of all the character string information in the real-time log information to obtain a dynamic encoding log includes:
generating a dynamic identification of the real-time log information;
calculating the data length of all character string information in the real-time log information;
summarizing the dynamic identification, the data length of the character string information and the character string information to obtain an initial coding log;
judging whether the length of the initial coding log is integral multiple of the preset number or not;
if the length of the initial coding log is integral multiple of the preset number, outputting the initial coding log as the dynamic coding log;
and if the length of the initial coding log is not an integral multiple of the preset number, performing data filling on the initial coding log until the length of the initial coding log after filling is the integral multiple of the preset number, and outputting the initial coding log after filling as the dynamic coding log.
In an optional embodiment of the present invention, the preset number may be 4.
In the embodiment of the present invention, the log information of the dynamic type may be numbered according to the maximum available value minus 1 in turn, for example, the dynamic identifiers are 65535, 65534, 65533, and … in turn.
In an alternative embodiment of the present invention, for example, for the string identifier "Buffer 0x12345678length 123content 66, 65", the encoded dynamic encoding log is "65535, 40," Buffer0x12345678length 123content a, B' ", where the first bit represents the dynamic string ID, the second bit represents the data length of the string information as 40, and the third bit represents the string information, and since the total length is 40, it is already an integer multiple of 4, so that the content does not need to be filled.
S5, mapping the character string information and the static encoding log or the character string information and the dynamic encoding log to obtain a log mapping table, and storing the log mapping table into a pre-constructed block chain.
In this embodiment of the present invention, the mapping the character string information and the static encoding log or the character string information and the dynamic encoding log to obtain a log mapping table includes:
extracting a static character string in the static coding log, replacing a parameter corresponding to the static character string with a preset placeholder to obtain a mapping character string, and constructing a static key value pair according to the static identifier and the mapping character string; or
Constructing a dynamic key value pair according to the dynamic identification and the dynamic coding log;
and summarizing all static key value pairs or all dynamic key value pairs of the log information to obtain the log mapping table.
In an embodiment of the present invention, the key-value pair may be a key-value pair, for example, for static type string information "Buffer 0x12345678length 123content 66, 65", and the encoded static encoding log is "1, 0x12345678,123,65, 66", the key value is 1, and the value is Buffer% p length% d content% c,% c, where% p,% d,% c are corresponding placeholders.
In the embodiment of the invention, the log mapping table is obtained by encoding the logs of different types, and only the encoded static encoding log or dynamic encoding log needs to be transmitted during storage and transmission, so that the requirements on storage and bandwidth in the storage or transmission of the log information of the equipment are greatly reduced. Meanwhile, the log mapping table comprises all types of key value pairs, and complete log information can be quickly found by searching the identification.
In another optional embodiment of the present invention, after the mapping is performed on the character string information and the static encoding log or the character string information and the dynamic encoding log to obtain a log mapping table, the method further includes:
extracting the equipment version number of the equipment end;
setting an equipment identification field and an equipment version field, filling the equipment unique identification into the equipment identification field, filling the equipment version number into the equipment version field, and summarizing the filled equipment identification field and the filled equipment version field to obtain an equipment state table;
and adding the status information of the real-time log information coding and mapping into the equipment status table, and storing the equipment status table to the block chain.
In this embodiment of the present invention, the device version number is used to identify version information of hardware and/or firmware of a device. For example, the device status table includes a device unique identifier Uuid: abcd, bcde, and cdef, current device Version number Version: x, Y, Z, Status of real-time log information encoding and mapping: level1, off, level2, and the like.
In another optional embodiment of the present invention, after storing the log mapping table in a pre-constructed blockchain, the method further includes:
acquiring the update log information of the equipment terminal according to a preset time interval;
and carrying out format coding on the updated log information, mapping the result of the format coding with the updated log information, generating a new log mapping table according to the key value pair obtained by mapping, and storing the new log mapping table in the block chain.
In the embodiment of the present invention, the time interval may be 1 day, and the log information updated every day is mapped into the log mapping table and stored in the block chain, so that the storage security of the log information and the traceability of the log information can be greatly improved based on the non-tamper property and the traceability of the block chain.
According to the invention, by accurately judging the type of the character string information and performing code conversion on different types of log information by using different methods, only the coded code log is stored during storage, and the occupation of the storage space and the network bandwidth of the log information during storage is reduced. Meanwhile, the log mapping table is stored through the block chain, and the safety and the traceability of the log information storage are greatly improved based on the non-tampering property and the traceability of the block chain. Therefore, the device log storage method provided by the invention can solve the problem that the log in the embedded device is difficult to store.

extracting the unique equipment identifier of the equipment terminal;
and extracting historical static character strings from the historical log information according to the unique equipment identifier, and summarizing the historical static character strings and preset extension character strings to obtain a static character string library.
In the embodiment of the present invention, the device unique identifier may be extracted from device information of a device side, where the device information includes the device unique identifier, a firmware version number of the device, log collection state information, and the like. The device unique identifier may be uuid, that is, a device may be uniquely identified by the device unique identifier, and the device unique identifiers of different devices are different. The history log information records log information of different devices.
Extracting the historical static character string from the historical log information according to the unique identifier of the equipment refers to extracting the static character string which has a corresponding relation with the unique identifier of the equipment from the historical log information.
In particular, a static string means that the string text is fixed and invariant, such as the string text "hello, world".
Or some fixed parts in the character string may be changed, but after the changed parts are described in a parameterization manner, the parameters themselves may completely describe the changed contents, for example, the character string is ' ″ data length% d ', data _ length ', where% d is a placeholder and data _ length is a parameter character string, and the display contents of the% d part are replaced according to the actual result of the runtime.
The extension string includes a reference statement, reference placeholder, etc., e.g., "% d" placeholder to reference other strings
In the embodiment of the invention, more accurate static character string library can be constructed by utilizing the historical log information and the preset extension character string.
For example, historical static strings include "hello, world", "data length", etc., and extension strings include placeholders such as "% d".
Specifically, the identifying the type of the real-time log information according to the static character string library constructed according to the character string information and the device information of the device side includes:
calculating the similarity between each piece of character string information and the character strings in the static character string library;
if the similarity between all the character string information and the character strings in the static character string library is greater than or equal to a preset similarity threshold, determining that the log information is of a static type;
and if the similarity between any character string information and the character strings in the static character string library is smaller than or equal to the similarity threshold, determining that the log information is of a dynamic type.
In the embodiment of the present invention, the static type indicates that all the character string information of the log is static character strings, and the dynamic type indicates that all the character string information is not static character strings, that is, the content of a character string cannot be determined completely or partially before actual operation, such as a character string returned from a network interface, or other character strings are referred to in the character string (for example, a character string referred to by using the% s placeholder of c language printf).
For example, the dynamic type log information is: < "hello,% s", name >, where name is the other string referenced.
In this embodiment of the present invention, the calculating the similarity between each piece of the character string information and the character strings in the static character string library includes:
and sequentially calculating the similarity between the character string information and the character strings in the static character string library by using the following similarity calculation formula:
wherein j (A, B) is the similarity, A is the character string information, and B is the character string in the static character string library.
In an optional embodiment of the present invention, the preset similarity threshold may be 100%. For example, string information < "hello,% s", name >, where name is the other string referenced. The segmented character string field comprises "% s", which represents a character string placeholder and is used for referring to other fields, and the character string field cannot be found in a static character string library, and then the character string information is determined to be in a dynamic type.
And thirdly, if the real-time log information is in a static type, performing fixed format coding on all character string information in the real-time log information to obtain a static coding log.
In the embodiment of the invention, because all the static type log information are static character strings, namely the character strings are fixed and unchangeable, the static type log information can be encoded according to a fixed format to obtain the static encoding log with smaller data size.
Specifically, the encoding all the character string information in the real-time log information in a fixed format to obtain a static encoded log includes:
generating a static identifier of the real-time log information;
extracting character string parameters corresponding to each static character string contained in the real-time log information;
and summarizing the static identification and the extracted character string parameters to obtain the static encoding log.
In this embodiment of the present invention, the log information of the static type may be numbered by sequentially increasing 1 according to the minimum available numerical value, for example, the static identifiers are sequentially 1, 2, 3, and ….
In an alternative embodiment of the present invention, five fixed fields may be used for encoding: string ID, parameter 1, parameter 2, parameter 3, parameter 4. For example, for the static type log information "Buffer 0x12345678length 123content 66, 65", the encoded static encoding log is "1, 0x12345678,123,65, 66", where the first bit indicates that the static string ID is 1, and the second bit to the fourth bit are, in turn, parameter 1 to parameter 4 corresponding to the static string.
When the information type of the log information is a static type, because the static type log information usually contains fixed and unchangeable character string content, if the description information (i.e., the static character string) and the key parameter value (and the parameter corresponding to the static character string) are stored and transmitted together, this will also bring great pressure to the storage space and the network bandwidth of the device, therefore, in this embodiment, by performing fixed format encoding on the static type log, the purpose of data compression can be achieved, and the excessive occupation of the storage space and the network bandwidth is reduced.
And fourthly, if the real-time log information is of a dynamic type, carrying out dynamic format coding on all character string information in the real-time log information to obtain a dynamic coding log.
In the embodiment of the present invention, since the dynamic type string information is not all static strings, that is, the strings are not fixed, encoding cannot be performed according to a fixed format.
Specifically, the dynamic format encoding of all the character string information in the real-time log information to obtain a dynamic encoding log includes:
generating a dynamic identification of the real-time log information;
calculating the data length of all character string information in the real-time log information;
summarizing the dynamic identification, the data length of the character string information and the character string information to obtain an initial coding log;
judging whether the length of the initial coding log is integral multiple of the preset number or not;
if the length of the initial coding log is integral multiple of the preset number, outputting the initial coding log as the dynamic coding log;
and if the length of the initial coding log is not an integral multiple of the preset number, performing data filling on the initial coding log until the length of the initial coding log after filling is the integral multiple of the preset number, and outputting the initial coding log after filling as the dynamic coding log.
In an optional embodiment of the present invention, the preset number may be 4.
In the embodiment of the present invention, the log information of the dynamic type may be numbered according to the maximum available value minus 1 in turn, for example, the dynamic identifiers are 65535, 65534, 65533, and … in turn.
In an alternative embodiment of the present invention, for example, for the string identifier "Buffer 0x12345678length 123content 66, 65", the encoded dynamic encoding log is "65535, 40," Buffer0x12345678length 123content a, B' ", where the first bit represents the dynamic string ID, the second bit represents the data length of the string information as 40, and the third bit represents the string information, and since the total length is 40, it is already an integer multiple of 4, so that the content does not need to be filled.
And step five, mapping the character string information and the static encoding log or the character string information and the dynamic encoding log to obtain a log mapping table, and storing the log mapping table into a pre-constructed block chain.
In this embodiment of the present invention, the mapping the character string information and the static encoding log or the character string information and the dynamic encoding log to obtain a log mapping table includes:
extracting a static character string in the static coding log, replacing a parameter corresponding to the static character string with a preset placeholder to obtain a mapping character string, and constructing a static key value pair according to the static identifier and the mapping character string; or
Constructing a dynamic key value pair according to the dynamic identification and the dynamic coding log;
and summarizing all static key value pairs or all dynamic key value pairs of the log information to obtain the log mapping table.
In an embodiment of the present invention, the key-value pair may be a key-value pair, for example, for static type string information "Buffer 0x12345678length 123content 66, 65", and the encoded static encoding log is "1, 0x12345678,123,65, 66", the key value is 1, and the value is Buffer% p length% d content% c,% c, where% p,% d,% c are corresponding placeholders.
In the embodiment of the invention, the log mapping table is obtained by encoding the logs of different types, and only the encoded static encoding log or dynamic encoding log needs to be transmitted during storage and transmission, so that the requirements on storage and bandwidth in the storage or transmission of the log information of the equipment are greatly reduced. Meanwhile, the log mapping table comprises all types of key value pairs, and complete log information can be quickly found by searching the identification.
In another optional embodiment of the present invention, after the mapping is performed on the character string information and the static encoding log or the character string information and the dynamic encoding log to obtain a log mapping table, the method further includes:
extracting the equipment version number of the equipment end;
setting an equipment identification field and an equipment version field, filling the equipment unique identification into the equipment identification field, filling the equipment version number into the equipment version field, and summarizing the filled equipment identification field and the filled equipment version field to obtain an equipment state table;
and adding the status information of the real-time log information coding and mapping into the equipment status table, and storing the equipment status table to the block chain.
In this embodiment of the present invention, the device version number is used to identify version information of hardware and/or firmware of a device. For example, the device status table includes a device unique identifier Uuid: abcd, bcde, and cdef, current device Version number Version: x, Y, Z, Status of real-time log information encoding and mapping: level1, off, level2, and the like.
In another optional embodiment of the present invention, after storing the log mapping table in a pre-constructed blockchain, the method further includes:
acquiring the update log information of the equipment terminal according to a preset time interval;
and carrying out format coding on the updated log information, mapping the result of the format coding with the updated log information, generating a new log mapping table according to the key value pair obtained by mapping, and storing the new log mapping table in the block chain.
In the embodiment of the present invention, the time interval may be 1 day, and the log information updated every day is mapped into the log mapping table and stored in the block chain, so that the storage security of the log information and the traceability of the log information can be greatly improved based on the non-tamper property and the traceability of the block chain.
According to the invention, by accurately judging the type of the character string information and performing code conversion on different types of log information by using different methods, only the coded code log is stored during storage, and the occupation of the storage space and the network bandwidth of the log information during storage is reduced. Meanwhile, the log mapping table is stored through the block chain, and the safety and the traceability of the log information storage are greatly improved based on the non-tampering property and the traceability of the block chain. Therefore, the device log storage device provided by the invention can solve the problem that the log in the embedded device is difficult to store.
