Description

Technical Field

[0001] The present invention relates to the field of servers, and more specifically, to a method, system, device and storage medium for realizing effective log positioning. Background Art

[0002] Servers are increasingly used in today's information society. As the number of servers increases, their management becomes increasingly complex. As an important tool for out-of-band management of servers, the role of BMC (Baseboard Management Controller) is becoming increasingly prominent. The BMC controller works with the BMC firmware to obtain various monitoring data on the server and give alarm information when necessary.

[0003] BMC monitors the running status of the server and records the changes in the server status in real time. As a part of monitoring, the main architecture of BMC software is to obtain the status of the sensor through a fixed sensor access interface and record the corresponding log according to the change of the status. During the monitoring process, BMC software will also print some debugging information for software developers to understand the current running status of BMC. If these debugging information are not controlled, some useful information will be overwritten due to continuous calls, and if stored, it will take up a lot of storage space.

[0004] In the early stage of project development, many debug logs will be added to the BMC software to facilitate problem analysis and early discovery of bugs (vulnerabilities). In the later stage of project development, the added debug logs are generally removed through macro switches or comments. Another way is to turn on the control switch manually when a problem is found, and the log will be printed out in real time, making it easy to know the status of each module in the current system. Collecting these logs can be used as a basis for problem analysis.

[0005] The method of reducing logs by removing them later is a static method. Although it avoids covering useful information, some information in the polling process cannot be obtained when problems occur, which is not conducive to problem analysis. The method of turning on the dynamic switch when a fault occurs can collect more information from the current BMC system, but there are two types of product failure phenomena. One is permanent failure, such as motherboard failure, irreparable memory failure, fan failure, etc. The other is related to the system operation status, single or irregular failure, such as CPU error, memory correctable error, hard disk and Raid card error during system operation. This type of error requires real-time capture of fault information to effectively analyze the cause of the fault. After seeing the fault, the manual turns on the dynamic switch to collect detailed logs. The collected logs are already outdated logs, especially for failures in the customer's room. The door-to-door visit time is later, which is not very useful for problem analysis. Summary of the invention

[0006] In view of this, the purpose of the embodiments of the present invention is to propose a method, system, computer device and computer-readable storage medium for realizing effective log positioning. The present invention establishes a global hash table by using function address and print function line number as key value, so as to ensure that duplicate redundant logs are not output, effective logs can be presented quickly and accurately, and more system historical information can be stored in limited storage space.

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0024] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0025] A first aspect of the embodiments of the present invention provides an embodiment of a method for effectively locating a log. Figure 1 FIG. 2 is a schematic diagram of an embodiment of a method for effectively locating a log provided by the present invention. Figure 1 As shown, the embodiment of the present invention includes the following steps:

[0026] S1, connecting the GPIO enable signal of the BMC chip in the motherboard to the CE chip select function pin of the Falsh chip, and setting the GPIO enable signal to a dynamic adjustment trigger;

[0027] S2. Establish a global log hash table by encapsulating the print function, and implement classification processing of log types according to the function address and function line number;

[0028] S3, in response to receiving a diagnostic debugging requirement of a log error, starting a log processing function of a single fault diagnostic debugging to collect fault information; and

[0029] S4. Output the fault information to the log display module and store it in a non-volatile flash memory to analyze and locate the problem.

[0030] The present invention divides the out-of-band management function of the server into a BMC control management module, a BMC log processing module, a log display module, a real-time dynamic switch module, and a corresponding function library hash table. The present invention embeds the function address library and function line number related to the fault log in the product system design, and presets the code address and code line of the device status of the processor, memory, hard disk, motherboard, external network card, external Raid card, backplane, power supply, fan in the system and the alarm function of the fault alarm, thereby improving the standardization of the log code.

[0031] The present invention first realizes the digital processing of component failures, and designs the error reporting type according to the difference of component failure error reporting, for example, type one: permanent failure, setting the status flag bit to 0; type two: single or irregular failure, setting the status flag bit to 1. In the BMC code design scheme of the present invention, state 0 is set as a static log, state 1 is set as a dynamic log, and the information is locked in the hash table function library.

[0032] Connect the GPIO enable signal of the BMC chip in the motherboard to the CE chip select function pin of the Falsh chip, and set the GPIO enable signal to be dynamically adjusted to trigger. By designing the Whitley platform motherboard, select a Flash chip, connect the GPIO enable signal of the BMC chip in the motherboard to the CE chip select function pin of the Falsh chip, and set it to be dynamically adjusted to trigger, so that storage logs can be recorded in time.

[0033] A global log hash table is established by encapsulating the print function, and the log type is classified according to the function address and the number of function lines.

[0034] In some embodiments, establishing a global log hash table by encapsulating the print function includes: setting the key value of the hash function to the address of the function in memory and the number of lines printed by the function, and setting the numerical value corresponding to the key value to the log printed in the corresponding line.

[0035] By encapsulating the print function, a global log hash table is established. The key value (Key) of the hash function uses the address of the function in memory and the number of lines printed by the function. The value (Value) corresponding to the Key is the log printed out of that line. Based on the uniqueness of the function address and the number of function lines in the process, the classification processing of log types is implemented. In the BMC code, the code processing, switch module processing, log code display, and overall control module are designed according to the logic. In the specific implementation process, the status log to be printed is marked in a print line code, and different types of logs are presented in the code display module respectively.

[0036] In response to receiving a diagnostic debugging requirement of a log error, a log processing function of a single fault diagnostic debugging is started to collect fault information.

[0037] In some implementations, the method further includes: determining a fault log processing logic according to a key status flag of the function library in the hash table.

[0038] In some embodiments, the fault log processing logic is determined based on the key status flag bits of the function library in the hash table, including: in response to a permanent fault appearing in the fault log, processing the fault as a single alarm; in response to an error report occurring in a single component being a single or irregular fault, performing deeper information collection.

[0039] In the log processing module of the present invention, the key status flag of the function library in the hash table determines the fault log processing logic: when the same fault component appears in the fault log and the fault error is a permanent fault, it is processed according to a single alarm, not multiple and repeated display according to the error time. When the error of a single component is a single or irregular fault, such as a processor error, a processor cache error, a processor core code error, a processor PCIE bus error, etc., the fault precise positioning log collection function is started.

[0040] The precise positioning log collection module is mainly a human-computer interaction module with the customer. It adopts a combination of hardware design and firmware design to achieve precise fault log collection, log storage, and log display. The specific design method is as follows:

[0041] By designing a non-volatile Flash storage device in the motherboard hardware and using the dynamic switch module as the entry for information access to this Flash device, a hardware serial port tool human-computer interaction device is designed. After the fault error is reported and the fault accurate positioning log is collected, offline or retrospective fault scenario diagnosis can be provided. In the log display module, the design interacts with the real-time log through log processing. At the same time, through the dynamic switch, the accurate fault log is printed in real time before the whole server is powered off. In the motherboard hardware design, the underlying firmware code is designed to generate log results based on the data type in the hash table. During the processing, the non-volatile Flash circuit is enabled in real time through the hardware enable signal, which acts on the CE chip select signal and the WPP voltage circuit. This part is used to replace the original design of obtaining accurate log functions through manual switches, and realize the log storage solution when the customer's room is unattended. The dynamic switch module is set between the BMC control management module and the log processing module. The enable code of the dynamic switch is set in the BMC control management module. When it is necessary to open and record detailed and more detailed log content according to the diagnosis and debugging requirements of the machine log error, this module issues instructions to the BMC control management module, and the BMC control management module starts the collection of the underlying detailed fault information of the faulty component. At the same time, this module also sends instructions to the log processing module. The log processing module changes the log processing mode, starts the log processing function of single fault diagnosis and debugging, collects the underlying detailed fault registers of the components output by the BMC control management module, and processes the registers in detail, and outputs more detailed fault information to the log display module and stores it in the non-volatile Flash module. In this way, when more historical log information is collected, combined with the current system dynamic log output, it will be convenient for effective analysis and positioning of the problem.

[0042] Based on the usage scenario of the machine in the customer's room, in the case of no one on duty, the present invention can accurately and timely record the machine's faults by designing a real-time dynamic switch, and provide the service engineer with a follow-up visit to the machine in the fault scenario. The dynamic switch has two functions, one is to trigger the real-time recording and output of the firmware-level log, and the other is to trigger the hardware information preservation. After all the logs are stored and collected, more information about the historical status of the system will be known, which is convenient for effective analysis of system faults.

[0043] The fault information is output to the log display module and stored in a non-volatile flash memory for problem analysis and location.

[0044] The embodiment of the present invention establishes a global hash table by using the function address and the number of printed function lines as key values, thereby ensuring that duplicate redundant logs are not output, valid logs can be presented quickly and accurately, and more system historical information can be stored in limited storage space.

[0045] It should be particularly pointed out that the various steps in the various embodiments of the above-mentioned method for realizing effective log positioning can be mutually crossed, replaced, added, and deleted. Therefore, these reasonable permutations, combinations and transformations for realizing effective log positioning should also belong to the protection scope of the present invention, and the protection scope of the present invention should not be limited to the embodiments.
