Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle log management, and in particular to a log speed limiting method, device and electronic equipment based on a vehicle-mounted AUTOSAR AP system LT module. Background Art
[0002] AUTOSAR AP (Adaptive Platform) middleware is widely used in vehicle-mounted ECU devices. The LT (Log and trace) module of AUTOSAR AP is used to print log information during program operation. Therefore, the LT module is widely used in AUTOSAR AP modules (such as CommunicationManagement, ExecutionManagement, Diagnostics, PlatformHealthManagement, etc.) and non-AUTOSAR AP applications.
[0003] At present, the target application using the LT module must have a log configuration file, which contains information such as the program identifier, log level, and log printing mode of the target application. In the mass production stage of vehicles, the log level of the target application is usually set to the ERROR level. However, the target application may print some ERROR log level logs in an endless loop, or print some non-error logs using the ERROR log level, or may enter an endless loop and keep printing ERROR log level logs due to the weak code of each module (such as the SOME / IP protocol stack). This will cause the log printing volume to deviate from the expected plan, there is a risk of exceeding the mass production log printing volume, and it will consume a lot of system and hardware resources. Therefore, when the target application of a mass-produced vehicle enters an endless loop and keeps printing logs, or the log printing frequency is too high, it is necessary to limit the log printing rate of the target application.

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] Traditional techniques cannot limit the log printing rate of the target application.
[0042] Based on this, in the log speed limiting method based on the LT module of the vehicle-mounted AUTOSAR AP system of the present invention, when the target application enters an infinite loop and keeps printing logs, or the log printing frequency is too high during the vehicle mass production stage, the LT module can be limited from consuming excessive resources by limiting the log printing rate (that is, by setting a threshold for the number of logs printed within a preset time window), thereby limiting the log printing rate of the target application.
[0043] To facilitate understanding of this embodiment, a log speed limiting method based on the LT module of the vehicle-mounted AUTOSAR AP system disclosed in an embodiment of the present invention is first introduced in detail.
[0044] Embodiment 1:
[0045] According to an embodiment of the present invention, an embodiment of a log speed limiting method based on an LT module of an on-vehicle AUTOSAR AP system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0046] Figure 1 is a flow chart of a log speed limiting method based on a vehicle-mounted AUTOSAR AP system LT module according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:
[0047] Step S102, when the target application calls the Create Logger interface of the LT module to create a logger object, the LT module reads the log configuration file of the target application, obtains the log printing information therein, and initializes the last log printing timestamp and the log printing counter to obtain initialization information, wherein the log printing information includes: the log level, the target application identifier, and the threshold value of the number of printed logs within the preset time window;
[0048] In an embodiment of the present invention, a method for limiting the log printing frequency is provided to prevent the system from being overwhelmed or exhausting resources by excessive log printing in order to ensure the stability and availability of the system in an environment with high log printing frequency.
[0049] During implementation, when the target application calls the Create Logger interface of the LT module to create a logger object, the LT module reads the log configuration file of the target application, parses the log level, target application identifier and log printing information of the threshold of the number of logs to be printed within the preset time window in the log configuration file, and saves the log printing information to the LT module. The threshold of the number of logs to be printed within the preset time window refers to the maximum number of logs allowed to be printed within the preset time window.
[0050] Step S104, when the target application calls the log printing function of the Logger object, the LT module performs speed-limited printing of the log according to the log printing information and initialization information.
[0051] It should be noted that, every time the target application calls the log printing function of the Logger object, the LT module executes a process of speed-limited log printing according to the log printing information and initialization information, that is, the process of step S104 is executed cyclically.
[0052] In an embodiment of the present invention, a log speed limiting method based on the LT module of the vehicle-mounted AUTOSAR AP system is provided, including: when the target application calls the Create Logger interface of the LT module to create a logger object, the LT module reads the log configuration file of the target application, obtains the log printing information therein, and initializes the last log printing timestamp and the log printing counter to obtain the initialization information, wherein the log printing information includes: the log level, the target application identifier and the threshold value of the number of logs printed within the preset time window; when the target application calls the print log function of the Logger object, the LT module performs the speed limiting printing of the log according to the log printing information and the initialization information. It can be seen from the above description that in the log speed limiting method based on the LT module of the vehicle-mounted AUTOSAR AP system of the present invention, when the target application enters an infinite loop and keeps printing logs, or the printing log frequency is too high during the vehicle mass production stage, the LT module is limited to consume too many resources by limiting the log printing rate (i.e., by setting the threshold value of the number of logs printed within the preset time window), that is, the log printing rate of the target application is limited, and the technical problem that the prior art cannot limit the log printing rate of the target application is alleviated.
[0053] The above content briefly introduces the log speed limiting method based on the LT module of the vehicle-mounted AUTOSAR AP system of the present invention. The specific contents involved are described in detail below.
[0054] In an optional embodiment of the present invention, initializing the last log printing timestamp and the log printing counter specifically includes the following steps:
[0055] (1) Set the last log print timestamp to 0;
[0056] Specifically, the last log printing timestamp t1 is set to 0.
[0057] (2) The log printing counter is set to 0, and initialization information in which the last log printing timestamp is 0 and the log printing counter is 0 is obtained.
[0058] In an optional embodiment of the present invention, the LT module performs speed-limited printing of logs according to the log printing information and the initialization information, specifically including the following steps:
[0059] (1) The LT module obtains the current timestamp and determines whether the difference between the current timestamp and the last log print timestamp is greater than the preset time window;
[0060] Specifically, if the current timestamp is t2, it is determined whether the difference between the current timestamp t2 and the last log printing timestamp t1 is greater than the preset time window.
[0061] (2) If it is greater, the log printing counter is set to 0, and the current timestamp is used as the last log printing timestamp, and then the log printing counter is increased by 1, and the log is printed;
[0062] (3) If not, determine whether the log printing counter reaches the print log quantity threshold;
[0063] (4) If reached, the log is not printed;
[0064] (5) If not reached, the log printing counter is incremented by 1 and the log is printed.
[0065] refer to Figure 2 The interaction timing diagram between the target application and the LT module is shown in FIG.
[0066] In an optional embodiment of the present invention, the target application is an application in a vehicle-mounted ECU device.
[0067] The present invention uses a preset time window current limiting algorithm, the principle of which is to limit the number of log prints within a preset time window (unit time). The algorithm divides time into fixed windows and limits the number of log prints within each preset time window. Assuming that the preset time window (unit time) is 1 second, and the threshold value for the number of log prints (i.e., the number of log prints) is 3, then within the unit time of 1 second, each time a log is printed, the log print counter increases by 1. If the value of the log print counter exceeds the threshold value of 3 for the number of log prints, subsequent logs will no longer be output. After 1 second is over, the log print counter is reset to zero and starts counting again. Figure 3 shown.
[0068] The log speed limiting method based on the LT module of the vehicle-mounted AUTOSAR AP system of the present invention can limit the LT module from consuming excessive resources by limiting the log printing rate when the target application enters an infinite loop and keeps printing logs or the log printing frequency is too high during the vehicle mass production stage.
