Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation manner of the present invention, and the embodiments are not contradictory.
As a common electronic device, various failures often occur in the using or developing process of the embedded device, and in order to enable a technician to locate the cause of the failure as soon as possible, system events occurring in the embedded device are usually recorded in a system log in real time and stored in a memory of the embedded device, wherein the system log includes system event information for describing the system events. For example:
and (3) error code: 0xA5
And (3) expression of characters: "Error A occurred with the Error code 0xA 5"
The time of occurrence: 20200328-193018
The log type: SYS
The generated system log is as follows: [20200328- & 193018] [ SYS ] Error A occurred with the Error code 0xA5. each character occupies 1 byte, and the system log occupies 65 bytes in total. When the user needs to view the system log, the system log displayed to the user is: [20200328- & 193018] [ SYS ] Error A occurred with the Error code 0xA5.
However, due to cost limitation, the embedded device usually uses a memory with a small storage capacity, a small space is used for storing the system logs, and the number of the stored system logs is small.
Fig. 1 is a flowchart illustrating a log storage method in an embodiment, and this embodiment relates to a specific process of how to reduce the number of bytes occupied by stored logs. The following describes implementation details of the log storage method according to the present embodiment in detail, and the following is only provided for facilitating understanding of the implementation details and is not necessary for implementing the present embodiment. As shown in fig. 1, the method includes:
The memory space for storing the system log in the electronic device is smaller than a preset threshold, for example, the electronic device may be an embedded device. The System event may be various types of events occurring on the electronic device, such as device restart, System clock exception, Global Navigation Satellite System (GNSS) location update data … …, and the System event information typically describes the System event by fixed characters, such as: the system event information of the system clock abnormity comprises the following information: SysTick enable! And nd it's interrupt interval is% d ms. When the system event currently occurring in the electronic device is determined, the system event can be described by the corresponding fixed character, that is, the current system event information is generated.
102, determining an identifier corresponding to the current system event information according to the corresponding relation between the system event information and the identifier; the number of bytes occupied by the identification is less than the number of bytes occupied by the system event information.
As can be seen from the above description, the system event information generally describes the system event using fixed characters, and a user can generally directly read the information described by the system event information. The identifier may be a number or a letter, which is not limited in this embodiment as long as the number of bytes occupied by the identifier is less than the number of bytes occupied by the system event information. That is, the system event information typically occupies a larger number of bytes than the identification. The correspondence between the system event information and the identifier may be preset, for example, as shown in table 1, one system event information is corresponded by one number. When the system event information is generated, the identifier corresponding to the current system event information can be determined according to the corresponding relationship between the system event information and the identifier.
TABLE 1
| Identification | System event information |
| 0 | CPU reset！And the reason is 0x％X. |
| 1 | SysTick enable！And it's interrupt interval is％d ms |
| 2 | RTC enable！And it's interrupt interval is％d ms |
| …… | …… |
| 100 | GNSS has closed |
| …… | …… |
And 103, generating a log corresponding to the currently occurring system event according to the identifier corresponding to the current system event information, and storing the log corresponding to the currently occurring system event into a memory.
When the identifier corresponding to the current system event information is determined, a log corresponding to the system event can be generated according to the identifier corresponding to the current system event information. When the log corresponding to the system event is generated according to the identifier corresponding to the current system event information, the system event information in the traditional system log can be replaced by the corresponding identifier to generate the log corresponding to the system event, and other contents in the log are kept unchanged. The log may include the contents as shown in table 2, where the number of bytes occupied by the identifier is 2, which is much smaller than the number of bytes occupied by the system event information.
TABLE 2
For example, the conventional system log is "[ 20200328- & 193018] [ GNSS ]: GNSS has closed. Wherein, the identifier corresponding to the system event information "GNSS has closed" is 100, and the log corresponding to the system event is generated according to the identifier corresponding to the current system event information as "[ 20200328 and 193018] [ GNSS ]:100 ]. That is, the number of bytes occupied by generating the log corresponding to the system event according to the identifier corresponding to the current system event information is smaller than the number of bytes occupied by generating the log according to the system event information.
The log storage method generates current system event information according to the current system event of the electronic equipment, and determining the identifier corresponding to the current system event information according to the corresponding relationship between the system event information and the identifier, further generating a log corresponding to the currently occurring system event according to the identifier corresponding to the current system event information, and stores the log corresponding to the currently occurring system event into the memory, because the number of bytes occupied by the identifier is less than the number of bytes occupied by the system event information, the number of bytes occupied by generating the log corresponding to the system event according to the identifier corresponding to the current system event information is less than the number of bytes occupied by generating the log according to the system event information, the memory space occupied by the logs corresponding to the currently-occurring system events is reduced, and the number of the system logs stored in the memory with limited space is increased.
In an embodiment, before determining the identifier corresponding to the current system event information according to the corresponding relationship between the system event information and the identifier, the event level of the current system event may be obtained first, and then whether the identifier corresponding to the current system event information needs to be determined according to the corresponding relationship between the system event information and the identifier according to the event level of the current system event is determined. This is described in detail below by means of the embodiment shown in fig. 2. As shown in fig. 2, the method further comprises:
For example, the event level of a system event may include one or more of DEBUG, INFO, WARN, ERROR, and EMERC; the event levels are DEBUG, INFO, WARN, ERROR and EMERC in sequence from low to high according to importance. Wherein, DEBUG: the log of the lowest level is represented, the importance degree of the information is general, and the output frequency is high; and (3) INFO: indicating that the importance level is higher than the DEBUG, the output frequency is generally lower than the DEBUG, and the INFO level is usually used to record some more important things that occur during normal use of the device; WARN: the representation importance degree is higher than the INFO grade but lower than the ERROR grade, and the grade is generally used for recording some common abnormal phenomena (abnormal phenomena which are not enough to cause software exception) which occur in the working process of the equipment; ERROR: representing a very important event grade, generally recording some serious abnormal phenomena occurring in the working process of the equipment by using the grade, wherein the serious abnormal phenomena are likely to cause the equipment to fail to work normally; EMERC: the log representing the highest level typically records significant system-level anomalies. Different system events correspond to different event classes.
When the event level of the currently occurring system event is not lower than the level threshold, determining the identifier corresponding to the current system event information according to the corresponding relationship between the system event information and the identifier, further generating a log corresponding to the currently occurring system event according to the identifier corresponding to the current system event information, and storing the log corresponding to the currently occurring system event into the memory. When the event level of the currently occurring system event is lower than the level threshold, the identifier corresponding to the current system event information does not need to be determined according to the corresponding relationship between the system event information and the identifier, that is, a log corresponding to the system event does not need to be generated according to the identifier corresponding to the current system event information, and the log corresponding to the currently occurring system event is stored in the memory. That is, when the event level of the currently occurring system event is lower than the level threshold, the log corresponding to the currently occurring system event is not stored.
According to the log storage method, the identification corresponding to the current system event information is determined according to the corresponding relation between the system event information and the identification only when the event grade of the current system event is not lower than the grade threshold, so that only the log of the system event of which the event grade is not lower than the grade threshold is generated when the log corresponding to the current system event is generated, and further only the log of the system event of which the event grade is not lower than the grade threshold is stored when the log is stored, and the limited memory space is more effectively utilized.
In an embodiment, when the event level of the currently occurring system event is not lower than the level threshold, before determining the identifier corresponding to the current system event information according to the correspondence between the system event information and the identifier, optionally, the level threshold is determined according to a level instruction input by a user.
The level instruction input by the user may be a voice instruction, a text instruction, or a touch instruction, which is not limited in the embodiments of the present application. The electronic device may determine the rating threshold based on the event rating indicated in the rating directive entered by the user.
According to the log storage method, the grade threshold value is determined according to the grade instruction input by the user, so that whether the log corresponding to the current system event is stored or not is determined according to the corresponding relation between the system event information and the identification according to the event grade of the current system event, the identification corresponding to the current system event information is determined, the log corresponding to the current system event is generated according to the identification corresponding to the current system event information, and when the log corresponding to the current system event is stored, whether the log is stored or not can be flexibly determined according to the requirements of the user.
In an embodiment, when the event level of the currently occurring system event is not lower than the level threshold, before determining the identifier corresponding to the current system event information according to the correspondence between the system event information and the identifier, optionally, the level threshold is determined according to the memory value of the remaining space of the memory.
For example, when the memory value of the remaining space of the memory is greater than the first preset threshold, the level threshold may be set to INFO, and when the event level of the currently occurring system event is not lower than INFO, for example, when the event level of the currently occurring system event is INFO, WARN, ERROR, or ERROR, the identifier corresponding to the current system event information is determined according to the correspondence between the system event information and the identifier, and then a log corresponding to the currently occurring system event is generated according to the identifier corresponding to the current system event information, and the log corresponding to the currently occurring system event is stored in the memory, that is, when the event level of the currently occurring system event is DEBUG, the log corresponding to the currently occurring system event is not stored. When the memory value of the remaining space of the memory is smaller than a second preset threshold, which is smaller than the first preset threshold, the level threshold may be set as the WARN, and only when the event level of the currently occurring system event is not lower than the WARN and is the WARN, ERROR or EMERC, the identifier corresponding to the current system event information is determined according to the corresponding relationship between the system event information and the identifier, and then the log corresponding to the currently occurring system event is generated according to the identifier corresponding to the current system event information, and the log corresponding to the currently occurring system event is stored in the memory. That is, when the event level of the currently occurring system event is DEBUG or INFO, the log corresponding to the currently occurring system event is not stored.
According to the log storage method, the grade threshold is determined according to the memory value of the residual space of the memory, so that the grade threshold is automatically determined according to the memory value of the residual space of the memory, and the intelligence of determining whether to store the log corresponding to the currently occurring system event according to the event grade of the currently occurring system event is improved. Meanwhile, by adopting the log storage method provided by the application, when the residual space of the memory is insufficient, the grade of the stored log can be intelligently adjusted so as to ensure that the important log can be stored.
In an embodiment, before determining the identifier corresponding to the current system event information according to the corresponding relationship between the system event information and the identifier, an event type of a system event currently occurring in the electronic device may be obtained first, and then it is determined whether to determine the identifier corresponding to the current system event information according to the corresponding relationship between the system event information and the identifier according to the event type, which is described in detail below with reference to fig. 3, as shown in fig. 3, the method further includes:
The system events may be divided into a limited number of event types according to specific events, for example, system events related to the system are divided into system classes; classifying system events related to GNSS positioning into GNSS classes; system events related to bluetooth low energy are classified as bluetooth low energy class. When a system event occurs, the event type of the system event may be determined based on the particular system event.
Wherein, the event type set comprises at least one event type. When the event type of the current system event belongs to the event type set, determining the identifier corresponding to the current system event information according to the corresponding relationship between the system event information and the identifier, further generating the log corresponding to the current system event according to the identifier corresponding to the current system event information, and storing the log corresponding to the current system event into the memory. That is, only if the event type of the currently occurring system event belongs to the set of system event types, the log of the system event is stored. When the event type of the currently occurring system event does not belong to the event type set, the identifier corresponding to the current system event information does not need to be determined according to the corresponding relationship between the system event information and the identifier, that is, the log corresponding to the currently occurring system event does not need to be generated according to the identifier corresponding to the current system event information, and the log corresponding to the currently occurring system event is stored in the memory. That is, when the event type of the currently occurring system event does not belong to the event type set, the log corresponding to the currently occurring system event is not stored.
In one possible case, when the corresponding identifier of the system event information is a number, the corresponding identifier of the system event information of the same event type may be an adjacent number, for example, as shown in table 3. When the event type is a system type, the corresponding mark of each system event information is a number between 0 and 99; when the event type is GNSS, the corresponding identifier of each system event information is 100-1000 digits; when the event type is the low power consumption bluetooth class, the corresponding identifier of each system event information is a number of 1001 and 2000.
TABLE 3
| Identification | Event type |
| 0-99 | System for controlling a power supply |
| 100-1000 | GNSS |
| 1001-2000 | Low power consumption Bluetooth |
| …… | …… |
According to the log storage method, only when the event type of the currently-occurring system event belongs to the event type set, the identifier corresponding to the current system event information is determined according to the corresponding relation between the system event information and the identifier, so that only the log of the system event of which the event type belongs to the event type set is generated when the log corresponding to the currently-occurring system event is generated, further, only the log of the system event of which the event type belongs to the event type set is stored when the log is stored, and the limited memory space is more effectively utilized.
In an embodiment, when the event type of the currently occurring system event belongs to the event type set, before determining the identifier corresponding to the current system event information according to the correspondence between the system event information and the identifier, optionally, a selection instruction input by a user is obtained, and the event type set is determined.
Wherein, the event type set comprises at least one event type. The selection instruction input by the user may be a voice instruction, a text instruction, or a touch instruction, which is not limited in the embodiments of the present application. The electronic equipment can select at least one event type from a plurality of event types according to a selection instruction input by a user, and the selected event type is used as an event type in the event type set; or according to a selection instruction input by a user, selecting a target event type from a plurality of event types, and using other event types as the event types in the event type set. It should be noted that, in one possible case, the target event type is null.
According to the log storage method, the event type set is determined according to the selection instruction input by the user, so that whether the log corresponding to the currently occurring system event is stored or not can be flexibly determined according to the requirement of the user when the log corresponding to the currently occurring system event is determined or not according to the event type of the currently occurring system event.
On the basis of the embodiment, the electronic device can also display the system event information corresponding to the log to be queried to the user according to the query instruction input by the user. As will be described in detail below with reference to fig. 4, as shown in fig. 4, the method further includes:
The query instruction received by the user may be a voice instruction received by the user, a text instruction received by the user, or a touch instruction received by the user, which is not limited in the embodiment of the present application. The query instruction is used for indicating a log to be queried. The log to be stored can be indicated by indicating the time of log generation, and the log to be stored can also be indicated by indicating the number of the log, which is not limited in the embodiment of the present application. The log to be stored indicated by the query instruction may be one log or a plurality of logs, which is not limited in this embodiment of the present application. For example, the log to be queried indicated by the query instruction is all the time between the time a and the time B when the log is generated.
And step 403, displaying system event information corresponding to the log to be queried.
When the log to be stored is obtained from the memory, the system event information corresponding to the log to be inquired is displayed to a user, so that the user can read the system event information and presume the fault type of the electronic equipment according to the system event information. Optionally, the system event information corresponding to the log to be queried is displayed according to the identifier in the log to be queried and the corresponding relationship between the system event information and the identifier. For example, when the identifier in the log to be queried is 100, the system event information corresponding to the log may be output as "GNSS has closed" according to the correspondence shown in table 1.
According to the log storage method, the system event information corresponding to the log to be queried is displayed through the identification in the log to be queried and the corresponding relation between the system event information and the identification, so that a user can visually read the system event information expressed by the log to be queried, the intuitiveness of the displayed system event information is improved, and the accuracy of the user for estimating the fault type of the electronic equipment according to the system log is improved.
In one embodiment, similar to the traditional approach, there are system events:
and (3) error code: 0xA5
And (3) expression of characters: "Error A occurred with the Error code 0xA 5"
The time of occurrence: 20200328-193018
The log type: SYS
Log corresponding ID: 100
Log level: WARN
Carrying data: error code
When the system log is stored, the stored system log is as follows:
a time stamp [1585395018], wherein the time stamp is converted to seconds since 1/00 of 1970, and takes 6 bytes of 4 bytes plus the character '[', ']';
log ID (2 bytes) 100;
carrying data: 0xA5, occupying 1 byte;
the check code takes 1 byte.
That is, the system log occupies 11 bytes in total, which is much smaller than the byte number occupied by the system log in the conventional method. When the user needs to read the system log, the system log displayed to the user is [ 20200328-.
