Description

Technical Field

[0001] The present disclosure relates to the technical field of status analysis, and particularly to a status analysis method, apparatus, and system. Background Art

[0002] The zero-terminal device is characterized by limited storage space, with flash less than 64M, or even 32M bytes. In the scenario of a secure video transmission system, the requirement that the terminal does not store secrets places many restrictions on the device. Various service modules inside the zero-terminal work together, and a large amount of data conduction and signaling interaction are required between processes to ensure the synchronization of their respective states. In actual use, it is usually necessary to switch parameter configurations according to the service scenario to achieve the purpose of optimal performance. However, due to the ever-changing external environment, once unexpected condition changes occur, it will always cause changes in performance indicators. For example, it is necessary to flexibly observe and adjust the state of the process. To address this problem, the usual solution is to write logs, write the logs to a file or print them to the serial port, analyze the Dump file, etc. However, due to the particularity of the zero-terminal environment, too many files cannot be written in the zero-terminal. In a confidential environment, the zero-terminal device is not allowed to be disassembled, and without an exposed interface, it is impossible to connect a serial cable or data cables such as USB or type-c.

[0047] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0048] Figure 1 It is a flowchart of a state analysis method provided by an embodiment of the present disclosure. As Figure 1 shown, the state analysis method includes the following steps:

[0049] Step 101: Obtain the registration application information of each process, and establish a process mapping table corresponding to each process according to the registration application information;

[0050] It should be noted that in the process mapping table, the information to be recorded includes but is not limited to: process name, which modules are included in each process, which instructions the process supports, and the supported callback function interfaces, etc.

[0051] Step 102: Obtain the log information reported by each dynamic link library and print and display it;

[0052] In this step, the log scheduler receives the log information reported by each dynamic link library and prints and displays this log information for the user to view.

[0053] Step 103: Obtain a control instruction and send the control instruction to the corresponding dynamic link library, where the control instruction is generated based on the log information reported by the user operating the dynamic link library.

[0054] In this step, when the user views the process log through the control panel, the user can send a control instruction to the zero terminal through the control panel.

[0055] In one embodiment, obtaining a control instruction and sending the control instruction to the corresponding dynamic link library includes:

[0056] Obtain the control instruction issued by the control panel and send the control instruction issued by the control panel to the corresponding dynamic link library;

[0057] In one embodiment, the control instruction can be divided into a local basic instruction set, a system instruction set, a process module custom instruction set, etc., and can be classified and extended according to the actual business situation.

[0058] Step 104: Instruct the corresponding dynamic link library to perform corresponding operations according to the control instruction and generate an instruction execution result.

[0059] In one embodiment, instructing the corresponding dynamic link library to perform corresponding operations according to the control instruction and generate an instruction execution result includes:

[0060] Instruct the corresponding dynamic link library to perform corresponding operations according to the control instruction issued by the control panel and generate an instruction execution result.

[0061] In one implementation, instructing the corresponding dynamic link library to perform corresponding operations according to the control instruction and generate an instruction execution result includes:

[0062] Instruct the corresponding dynamic link library to adjust process parameters, modify the log level, intercept process variables, or collect intermediate data according to the control instruction.

[0063] It should be noted that the control instruction in this embodiment is sent in accordance with a pre-agreed format. An exemplary instruction format is as follows:

[0064] [PROC|SYS|LOCAL][::Process][::Module][::CMD][Para]

[0065] Among them, [PROC|SYS|LOCAL] represents instruction set information, which is mainly divided into three major categories of instruction sets: PROC refers to instructions sent to a certain process, SYS refers to instructions sent to the system, and LOCAL refers to instructions sent to LogPub locally; [::Process] represents the process name; [::Module] represents the module name; [::CMD] represents the module name; [Para] represents the parameter.

[0066] The symbol "|" means "or".

[0067] The symbol "[]" means an optional item.

[0068] The symbol "::" means a separator.

[0069] For example: PROC::processA::audio_module::log DEBUG

[0070] It means to modify the log level to the debug level for the audio management module audio_module of the process ProcessA under the PROC instruction set.

[0071] It can be arbitrarily extended according to the above specific format.

[0072] The SYS instruction set includes but is not limited to modifying the log file size, cache quantity, whether to capture Dump information, modifying the mode, etc.

[0073] The LOCAL instruction set includes but is not limited to viewing the system version, modifying permissions, modifying passwords, notifying to open or close the sending channel, opening or closing local printing, etc.

[0074] The PROC instruction set includes but is not limited to log level filtering, extended instruction callback, etc.

[0075] Step 104, instruct the corresponding dynamic link library to perform corresponding operations according to the control instruction and generate an instruction execution result.

[0076] In one embodiment, instructing the corresponding dynamic link library to perform corresponding operations according to the control instruction and generate an instruction execution result includes:

[0077] Instruct the corresponding dynamic link library to adjust process parameters, modify the log level, intercept process variables, or collect intermediate data according to the control instruction.

[0078] Step 105, obtain the instruction execution result and report the instruction execution result to the control panel.

[0079] In this step, the dynamic link library provides several interfaces in standard formats, and one set of them are functions for process modules to call. After receiving an instruction, the module performs corresponding operations according to the instruction. After the operations are completed, the execution results are sent back to the log scheduler through the interfaces provided by the dynamic link library in a specified format.

[0080] The instruction execution results usually include: filtered logs, instruction return results, and so on.

[0081] Specifically, since a large number of log printing statements are added to the source code of the process module, such as: LogD(.....), LogI(.....), LogW(.....), LogE(......), etc., different log contents can be printed for different branches and different conditions in the code. All the printed log contents will be uniformly aggregated to LogKey, and LogKey filters the log contents according to the log levels set by the user. For example, only the ERROR-level logs are displayed, and other logs are not sent to LogPub and are directly discarded, so that the user cannot see this part of the log contents. Therefore, in this embodiment, the filtered logs refer to the logs obtained after filtering all the logs according to the log levels set by the user.

[0082] In one embodiment, after each control instruction is executed, the instruction execution result corresponding to the control instruction is immediately reported to the control panel.

[0083] In this embodiment, since the amount of logs is related to the business and may be very large, 1000 or more per second. To ensure that instructions are not lost, during internal processing, the sending and uploading of instructions are queued. In the normal log reporting traffic, the content of the instruction reply is reported in real time to avoid reply queuing and poor user experience.

[0084] A state analysis method provided by an embodiment of the present disclosure allows external parties to flexibly modify specific log levels to view the status, intermediate variables of any process during operation, and even when the process crashes, it can capture the crash signal, backtrace the function call stack, and translate the crash address into the corresponding source code file line number.

[0085] It should be noted that before the control panel connects to the log scheduler, the log information reporting channel of the dynamic link library can be closed. In this way, the reported logs are filtered out at the address source end, that is, inside the process. That is to say, the dynamic link library does not send logs until it receives the notification disappearance message from the log scheduler. After the control panel is connected, the dynamic link library opens the channel and reports the log content to the log scheduler one by one. It can also redirect the logs to the local according to the settings of the log scheduler. If a systematic catastrophic event occurs before the control panel is connected, it can also be recorded locally first, and then collected by the user after opening the Ctrl Panel. This can ensure that some unknown serious faults can be well preserved and viewed. Various processes also record the internal major event processes, such as whether there has been a crash and restart, whether the connected account has been disconnected, and whether there has been a reconnection, etc., which are recorded according to the user's needs for future viewing.

[0086] Figure 2 The present disclosure provides a flowchart of a state analysis method for an embodiment. As Figure 2 shown, the state analysis method includes the following steps:

[0088] Step 202, the control panel issues a control instruction to the log scheduler;

[0089] Step 203, the log scheduler receives the control instruction and sends the control instruction to the corresponding dynamic link library, where the control instruction is generated according to the log information reported by the user's operation of the dynamic link library;

[0090] Step 204, the corresponding dynamic link library performs corresponding operations according to the control instruction, generates an instruction execution result, and sends the instruction execution result to the log scheduler;

[0091] Step 205, the log scheduler receives the instruction execution result and reports the instruction execution result to the control panel.

[0092] Step 206, the control panel presents the instruction execution result to the user.
