Description
Technical Field
The present invention relates to the field of log processing, and in particular, to a log processing method and system, an electronic device, and a storage medium.
Background
A log (log) refers to a collection of certain operations of objects specified by the system and their results in time order. The log file is a log file, records interactive information between a system and a user of the system, and is a data collection method for automatically capturing the interactive type, content or time between a person and a system terminal; for web searches, a log is an electronic record of a user searching for information using a web search engine interacting with the web search engine during the search for information.
Along with the increasing complexity and the increasing strength of the functions of the mobile phone, the log quantity generated by the mobile phone system is increased, and due to the difference in the function realization of each subsystem in the chip, the log format of each subsystem is inevitably different greatly, so that it is difficult to achieve a better log compression ratio and compression overhead by using a uniform data compression algorithm. Each subsystem manages the log independently, so that log entries finally stored in an external memory are scattered, and later system-level log data analysis and mining are inconvenient.
For the mobile phone software test version, the log quantity generated in the operation process is much larger than that of the formal version, and the conventional external memory such as an eMMC (embedded memory) or a TF-Card (TF storage Card), even the conventional PC (Personal Computer) hard disk, cannot completely meet the requirement of continuously storing a large quantity of logs in the external field test, so that the logs are easily lost or covered.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a log processing method, which is applied to electronic equipment, wherein the electronic equipment comprises a plurality of subsystems for realizing different functions. According to the log processing method, the contents of the non-attribute values in the logs of the subsystems are encoded in a uniform encoding format, so that the number of logs, the cost for frequently preparing log character strings and the cost for log transmission are greatly reduced after the logs are compressed, and the compression ratio of the logs is improved.
In some optional embodiments, the electronic device includes a plurality of cellular communication subsystems such as a Modem for implementing a cellular communication function, a Wireless connection processor subsystem such as a WCN (Wireless Connectivity Network) for processing Wireless services such as Wi-Fi, a MultiMedia processor subsystem such as a MultiMedia, application processor ap (application processor) subsystem for processing MultiMedia related services, and a system processor sp (system processor) subsystem for processing system level services.
The log processing method provided by this embodiment specifically includes the following steps, as shown in fig. 1:
and S101, encoding the contents of the non-attribute values in the log by adopting a uniform encoding format for each subsystem. Wherein, the attribute value is a specific feature or parameter defining the attribute, and the content other than the attribute value is the content except the attribute value.
In step S101, the original content is replaced with the encoded result for the content having no attribute value. In a specific example, a log includes attribute values and non-attribute values, and the format of the log is changed to "# M2$0.5$ 3" after the non-attribute values are encoded. Wherein, 0.5 and 3 are attribute values, and the rest contents are the contents of encoded non-attribute values.
It should be noted that the coding format adopted in step S101 for each subsystem may be defined by itself, or may use the prior art. In this embodiment, in order to subsequently compress the log by using an algorithm that is suitable for all the subsystems and has a high compression rate, the contents of the non-attribute values in each subsystem are uniformly encoded, that is, the format of the log in each subsystem is unified.
And S102, respectively compressing the logs in each subsystem, and summarizing the compressed logs of each subsystem according to the synchronous signals.
In an alternative embodiment of step S102, each subsystem includes a group of ping-pong buffers, and for each subsystem, the logs in the ping-pong buffers that do not currently perform the log storing operation are compressed. In specific implementation, each subsystem includes a log management module LogManager, the LogManager switches ping-pong buffers for temporarily storing logs back and forth, and compresses logs temporarily stored last time, that is, logs stored in ping-pong buffers not currently executing log storage operation, specifically using hardware compression or software compression. In one example, for a multimedia processor subsystem, including ping-pong buffer1 and ping-pong buffer2, a LogManager of the multimedia processor subsystem is enabled to perform ping-pong buffer switching based on a synchronization signal and compress a log in the ping-pong buffer before switching. The specific process is as follows: if the current ping-pong buffer1 is executing the operation of storing the log, the LogManager is notified to switch to using the ping-pong buffer2 to store the log, and after the switching of the ping-pong buffer is completed, the log in the ping-pong buffer1 is compressed. In another example, the LogManager in the subsystem switches the ping-pong buffer for storing the log according to the full signal of the ping-pong buffer, and compresses the log in another ping-pong buffer which does not execute the storing operation.
In a specific implementation, the synchronization signal is sent out by a log management module SysLogManager of the system. In an optional implementation manner, each subsystem uploads the compressed log to a log management module SysLogManager of the system to implement log aggregation.
In an alternative embodiment, the synchronization signal is generated at intervals. In this embodiment, the compressed logs of each subsystem are collected at regular intervals. In an alternative embodiment, the synchronization signal is generated for completing transmission of the packed log. In this embodiment, the operation of summarizing the compressed logs of the subsystems is executed after the packed logs are transmitted.
It should be noted that, in an implementation, the period of the synchronization signal is controlled according to the log throughput of each subsystem and the size of the ping-pong buffer in each subsystem, so as to avoid the ping-pong buffer overflow or the log loss.
In order to facilitate subsequent analysis of the log, in an optional implementation manner of step S102, the log after compression of each subsystem is summarized according to the sequence of the timestamps.
And step S103, packaging the collected logs and transmitting the packaged logs to at least one external memory.
In a specific implementation of step S103, the assembled log is packaged by the log packaging processing module LogPackage, and the packaged log is transmitted to the external memory by the log output module LogOut. In an alternative embodiment, the LogPackage packs the summarized logs according to a uniform format, for example, packs the summarized logs in a format of { timestamp, subsystem to which the summarized log belongs, sub-function to which the summarized log belongs }. Wherein, the sub-function may be power consumption.
In the specific implementation of step S103, LogOut may transmit the packaged log to one external memory, or may transmit the packaged log to a plurality of external memories, so as to meet the requirement of storing a large amount of logs. In a specific implementation, the selection of which external storage or storages to transmit the packed log may be based on a test scenario, a real-time transmission overhead condition, or a system limitation.
The external memory may be a board-level memory installed in the electronic device, such as a TF-Card, an eMMC, a UFS (UNIX file system) or a Flash (memory chip), which may meet the requirement of storing test logs in most laboratories; the memory can also be a memory of other electronic equipment, for example, a hard disk of a PC (personal computer) connected with the electronic equipment in a wired manner, and the memory can meet the log storage requirement of a common external field pressure test; the storage on the server can also be used, for example, a hard disk on the server wirelessly connected with the electronic device, which can meet the log storage requirement of a plurality of electronic device terminal tests. It should be noted that the external memory is not limited to the above example, and may be any memory other than the electronic device.
The electronic device in this embodiment may be a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), and the like. Fig. 2 is a block diagram for illustrating a connection relationship between an electronic apparatus and an external memory. In the example shown in fig. 2, the electronic device includes five subsystems, i.e., a Modem, a WCN, a SP, a Multimedia, and an AP, and is connected to the TF-Card through a board interface, a PC through a wired connection, and a server through a wireless connection.
The following is an example of how the mobile phone selects the external memory to store the log.
In one example, the handset decides whether to transfer the log to the TF-Card based on whether the presence of the TF-Card is detected. Specifically, if the mobile phone detects that a TF-Card exists, the log is transmitted to the TF-Card, and if the mobile phone does not detect the TF-Card, the log is transmitted to other external storage, such as a hard disk of a PC or a hard disk on a server.
In another example, the mobile phone determines whether to transmit the log to the memories of other electronic devices according to whether the USB interface has established a data connection and whether the electronic device connected with the mobile phone through the USB has an open storage space. Specifically, if the mobile phone detects that the USB interface has established a data connection and the electronic device connected to the mobile phone via the USB has opened a storage space, the log is transmitted to the electronic device, otherwise, the log is transmitted to another external storage, such as a hard disk on a server.
In another example, the mobile phone is connected to a plurality of external memories, and the mobile phone determines to which external memory the log is transmitted according to the size of the log. For example, if the size of the log exceeds a first threshold, the log is transmitted to a TF-Card installed in the mobile phone; if the size of the log exceeds a second threshold value, transmitting the log to a PC (personal computer) connected with the mobile phone through a wire; and if the size of the log exceeds a third threshold value, transmitting the log to a server in wireless connection with the mobile phone. In this example, the third threshold is greater than the second threshold, which is greater than the first threshold.
In another example, the mobile phone determines which external memory to transfer the log to according to the remaining storage space of the external memory, in addition to considering the log size.
