The digital virtual instrument adopts a Linux system, and the central control entertainment system and the auxiliary driving entertainment system adopt an Android system.
Taking the above-mentioned vehicle-mounted infotainment system as an example, when the sub-entertainment system is an Android system, the native log collection tool logcat of the Android system may be called to collect the current system log generated by the sub-entertainment system in real time, and store the current system log in a log partition of an Embedded multimedia controller (EMMC) built in the Android system.
The system logs generated by the Android system may include a kernel dmesg log, a kernel global log, a tomstone log, an Application Not Responding (ANR) log, and the like. Optionally, a log obtaining tool diagnostics may be used to capture a dmesg log (kernel log) in the Android system, then the kernel log is output through an Android native printing log interface, and finally the log is stored to the corresponding log partition by the logcat module.
In another specific embodiment, when the child entertainment system is a Linux system, the Linux system native log collection tool Ulogcat may be called to collect the current system log generated by the child entertainment system in real time, and store the current system log in the log partition of the built-in EMMC of the Linux system.
Optionally, when the Ulogcat process is started, first detecting whether an old log file exists in a log partition in the Linux system, if so, renaming the log file as log _ last, and then backing up the collected system log to the log partition in the built-in EMMC.
The system logs generated by the Linux system may include kernel dmesg logs, kernel global logs, process coast logs and the like.
And step 120, compressing the current log stored in the log partition through a log management tool, so that the log collection tool stores the collected new system log in the log partition.
In this embodiment, in order to save the storage space occupied by the system log in the log partition and improve the utilization rate of the log partition, the current log stored in the log partition may be compressed by the log management tool, and then the collected new system log is stored in the log partition by the log collection tool.
In a specific embodiment, when the entertainment subsystem is an Android system, a UsbLog module in the Android system may be called to compress a current log stored in the log partition. After the UsbLog module is started, firstly checking whether an uncompressed log file exists in a log partition, if so, firstly compressing the uncompressed log file, and then calling an Android system native logcat module to store the collected new system log in the log partition.
In another specific embodiment, when the child entertainment system is a Linux system, a logMgr module within the Linux system may be invoked to compress the current log stored in the log partition. When the logMgr module is started, whether a log file named log _ last exists in the log partition is checked, if so, the log file named log _ last is compressed, and then the native Ulogcat module of the Linux system is called to store the collected new system log in the log partition.
In this embodiment, optionally, when the sub-entertainment system is an Android system, the size of the corresponding log partition may be 256 MB; when the child entertainment system is a Linux system, the corresponding log partition may be 128MB in size.

In the embodiment, after the current system logs generated by the sub-entertainment system in real time are collected by the log collection tool, invalid logs are screened from the collected system logs, and after the invalid logs are removed, the remaining system logs are stored in the log partitions corresponding to the sub-entertainment system; secondly, in order to reduce the printing amount of the system logs, the log collection tool may output the collected logs to the log partition according to a preset batch number, for example, the log collection tool may count the number of the collected current system logs, and if the number of the collected current system logs is greater than or equal to 100, the collected current system logs may be output in batch. Specifically, the format of the system log stored in the log partition may be "log _ serial number _ year, month, day, hour, minute, and second".
According to the technical scheme of the embodiment of the invention, the log collection tool is used for collecting the current system log generated by the sub-entertainment system in real time in the vehicle-mounted information entertainment system, the current system log is stored in the log partition corresponding to the sub-entertainment system, and then the log management tool is used for compressing the current log stored in the log partition so as to enable the log collection tool to store the collected new system log in the log partition, so that the labor cost required in the log collection process can be reduced, and the collection efficiency of the system log in the vehicle-mounted information entertainment system is improved.
On the basis of the above embodiment, after compressing the current log stored in the log partition by the log management tool, the method further includes:
and step 130, acquiring the log capacity of all the system logs stored in the log partition through the log management tool.
And 140, judging whether the log capacity is larger than a preset capacity or not, and whether the log partition meets a log coverage condition or not.
In an implementation manner of the embodiment of the present invention, when the log management tool obtains log capacities of all system logs stored in a log partition, the method further includes: and acquiring the number of the system logs stored in the log partition and the residual storage space of the log partition by the log management tool.
Wherein, judging whether the log partition meets the log coverage condition comprises: judging whether the number of the system logs stored in the log partition is larger than a preset number or not, or whether the residual storage space of the log partition is smaller than a preset threshold value or not; and if so, confirming that the log partition meets the log coverage condition.
In a specific embodiment, if the number of the system logs stored in the log partition is greater than 100, or the remaining storage space of the log partition is less than 30MB, it is determined that the log partition satisfies the log coverage condition. The preset number and the preset threshold are set according to actual conditions, which is not limited in this embodiment.
And 150, if the log capacity is larger than the preset capacity and the log partition does not meet the log coverage condition, compressing all the system logs stored in the log partition by the log management tool, and returning to execute the operation of collecting the current system log generated by the sub-entertainment system in real time by the log collection tool in the step 110.
In the present embodiment, the preset capacity may be set to 10MB, and the specific value is set in practical situations, which is not limited by the present embodiment. Wherein, if the log capacity of all the system logs stored in the log partition is greater than 10MB but the log partition does not satisfy the log coverage condition, all the system logs stored in the log partition can be compressed by the log management tool (the compression rate can be set to 5% -10%).
And 160, if the log capacity is larger than the preset capacity and the log partition meets the log coverage condition, deleting the first system log stored in the log partition according to the storage time corresponding to each system log in the log partition, and returning to execute the operation of collecting the current system log generated by the child entertainment system in real time through the log collection tool in the step 110.
In this embodiment, if the log capacity of all the system logs stored in the log partition is greater than 10MB and the log partition meets the log coverage condition (i.e. the number of the system logs is greater than 100, or the remaining storage space of the log partition is less than 30MB), the system log stored first in the log partition is deleted.
The method has the advantage that developers can conveniently obtain the latest log generated by the vehicle-mounted infotainment system in time so as to analyze the current fault of the vehicle-mounted infotainment system.
Example two
Fig. 2 is a flowchart of a method for exporting a system log according to a second embodiment of the present invention, where the method is applicable to a case of exporting a system log generated by a vehicle-mounted infotainment system, and the method may be executed by a device for exporting a system log, where the device may be implemented by software and/or hardware, and may be generally integrated in a central control entertainment system in a vehicle-mounted infotainment system, and specifically includes the following steps:
and step 210, after receiving a log obtaining instruction sent by a server, obtaining a first target log matched with the log obtaining instruction in a log partition corresponding to the central control entertainment system.
In this embodiment, a vehicle-mounted infotainment system including two Android systems and one Linux system is taken as an example, in the vehicle-mounted infotainment system, a central control infotainment system adopts the Android system, and a non-central control infotainment system includes a copilot entertainment system adopting the Android system and a digital virtual instrument adopting the Linux system.
In the present embodiment, each Vehicle has a unique Vehicle Identification Number (VIN). When a vehicle-mounted infotainment host in a certain vehicle breaks down, a developer can send a log obtaining instruction to the vehicle-mounted infotainment host through a server according to the VIN of the vehicle so as to obtain a system log generated in a specified time period by a vehicle-mounted infotainment system in a specified vehicle. The server can send a log acquisition instruction to the vehicle-mounted infotainment host through a Message Queue Telemetry Transport (MQTT) protocol.
After the instruction is sent, the server regularly monitors whether the vehicle is connected with the network or not, and if the condition that the vehicle is connected with the network is detected, the log time period needing to be collected is sent to the Android application of the central control entertainment system. After receiving the log obtaining instruction and the log time period, the central control entertainment system can screen the log matched with the log time period in the corresponding log partition as a first target log.
In this embodiment, after receiving the log obtaining instruction sent by the server, the central control entertainment system may create a client (i.e., an FTP client) using a File Transfer Protocol (FTP), and then connect the created FTP client with an FTP server created by another non-central control entertainment system in the in-vehicle infotainment system. After the connection is successful, the central control entertainment system sends a log obtaining instruction to each connected non-central control entertainment system, so that each non-central control entertainment system obtains a second target log matched with the log obtaining instruction in a corresponding log partition.
In this embodiment, after each non-central control entertainment system acquires the second target log matched with the log acquisition instruction in the corresponding log partition, the second target log may be sent to the central control entertainment system. And after receiving the second target logs sent by the non-central control entertainment systems, the central control entertainment system sends the first target logs and the second target logs to the server.
In this embodiment, after the server obtains the first target log and the second target log through remote connection, the server may notify the developer of successful log obtaining through an automatic mail notification; if the server cannot acquire the log within the specified time, the developer can be notified of the failure of log acquisition in the same way.
In a specific embodiment, after the server acquires the first target log and the second target log through the remote connection, a developer may export the first target log and the second target log through a Universal Serial Bus (USB) interface in the server.
In this embodiment, if the vehicle-mounted infotainment host fails, a developer can export the log generated by the vehicle-mounted infotainment system through the remote server, and compared with the mode that the developer obtains the system log from an actual vehicle in the prior art, the method provided by the embodiment does not need the cooperation of a vehicle owner, can reduce the difficulty of the fault repairing process, and improves the experience of the user on the vehicle; secondly, a log obtaining instruction is sent to the vehicle-mounted infotainment host through the server, the system log generated by the vehicle-mounted infotainment system can be quickly obtained, and the problem that the fault cannot be repaired due to the fact that a developer cannot timely obtain the system log related to the fault can be avoided.
The technical scheme of the embodiment of the invention obtains the first target log matched with the log obtaining instruction in the log partition corresponding to the central control entertainment system after receiving the log obtaining instruction sent by the server, the log retrieval instructions are then sent to at least one non-central entertainment system connected to the central entertainment system, so that each non-central control entertainment system acquires a second target log matched with the log acquisition instruction in a corresponding log partition, and finally sends the first target log and the second target log to the server, a technical means for making the user obtain the first target log and the second target log according to the server, the method can reduce the labor cost required by the log exporting process, reduce the difficulty of the fault repairing process and improve the exporting efficiency of the system log in the vehicle-mounted information entertainment system.
EXAMPLE III
This embodiment is a further refinement of the above embodiment, and the same or corresponding terms as those of the above embodiment are explained, and this embodiment is not described again. Fig. 3 is a flowchart of a method for exporting a system log provided in a third embodiment, in the third embodiment, a technical solution of the present embodiment may be combined with one or more methods in the solutions of the foregoing embodiments, as shown in fig. 3, the method provided in the present embodiment may further include:
and 310, after receiving a log obtaining instruction sent by a server, obtaining an alternative log matched with the log obtaining instruction in a log partition corresponding to the central control entertainment system according to a target time period included in the log obtaining instruction and a preset target log grade.
In this embodiment, since too much system log output may affect the performance of the entire in-vehicle infotainment system, this embodiment further provides an implementation manner of obtaining the target log according to the target log level. Wherein, the target log level is preset in the vehicle-mounted infotainment system by a developer according to the actual development condition of the vehicle. The target log level includes Error (Error), Warning (Warning), normal (Info), and Debug (Debug), among others.
In the present embodiment, if the in-vehicle infotainment host in the vehicle is in the trouble shooting period after production, the target log level may be set to the normal level; the target log level may be set to an error or warning level if the in-vehicle infotainment host in the vehicle is in a product stable period after production.
In a specific embodiment, the setting criteria of each log level may specifically be as follows:
debug: after the log level is set to Debug for the log level used by the vehicle-mounted infotainment host, the log stream printed by a developer in the development and debugging stage and the information output by the log are the most;
info: compared with the debugg grade log, the method has the advantages that the key and necessary log which is beneficial to problem recall is printed, the log which is not necessary for problem recall is removed, the vehicle-mounted infotainment host adopts the log grade after mass production, and the information output by the log is less than the debugg grade.
Turning: the log is used for recording the log which can cause the application program to be abnormal, but can automatically recover the application program and does not cause abnormal actions, and the information output by the log is less compared with the information level;
error: the information used to record any critical error operations and abnormal states found by an Application (APP) is less in the amount of information logged than the Warning level.
In this embodiment, after the completion of the setting of the log level in the in-vehicle infotainment system, the in-vehicle infotainment system needs to be restarted to validate the set log level.
In an implementation manner of the embodiment of the present invention, in a log partition corresponding to the central entertainment system, acquiring an alternative log matching the log acquisition instruction according to a target time period included in the log acquisition instruction and a preset target log level includes:
and 311, in a log partition corresponding to the central control entertainment system, screening a plurality of system logs matched with the target time period according to the target time period included in the log obtaining instruction and the storage time of each system log included in the log partition.
And step 312, taking the system log with the log grade greater than or equal to the target log grade as the alternative log in the plurality of system logs matched with the target time period.
In this embodiment, each log level corresponds to a priority, and the log levels may be arranged from high to low according to the priorities, where the arranged log levels are Error, Warning, Info, and Debug.
In this step, among the plurality of system logs that match the target time period, the system log whose log level is greater than or equal to the target log level is output as the candidate log, that is, only the system log whose log level is greater than or equal to the set log level.
In a specific embodiment, assuming that the preset target log level in the in-vehicle infotainment system is the Info level, because the Debug level is not greater than the Info level, the system logs related to the Debug level are not output, and only the system logs related to the Error, Warning and Info levels are output.
In another specific embodiment, a developer may set a target log level in an in-vehicle infotainment system to a Debug level prior to mass production of in-vehicle infotainment hosts in a vehicle; after mass production is carried out on the vehicle-mounted infotainment host in the vehicle, developers can set the target log level in the vehicle-mounted infotainment system as the Info level; after one year of mass production of in-vehicle infotainment hosts in vehicles, developers may set a target logging level in an in-vehicle infotainment system to a Warning level.
And 320, removing the invalid logs in the alternative logs according to a preset log filtering rule to obtain a first target log.
In a specific embodiment, whether a system log related to user privacy information (such as user account information, picture information, contact information and the like) exists in the alternative logs can be detected, and if yes, the system log is taken as an invalid log; secondly, whether a system log which is not related to the current fault of the vehicle-mounted infotainment host exists in the alternative logs can be detected, and if yes, the system log is used as an invalid log.
In this embodiment, an embodiment is further provided for limiting a log level in a third party application Development Kit (SDK) and an Android Application Package (APK) installed in the in-vehicle infotainment host according to a target log level preset in the in-vehicle infotainment system. For example, when the target log level preset in the in-vehicle infotainment system is the Info level, the log level in the third-party application should also be the Info level.
