In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0027] Among them, in the description of the embodiments of the present invention, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a way to describe the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present invention, "multiple" refers to two or more than two.

[0028] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0029] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0030] The following is a detailed description of a specific solution of a device for checking missing processes after system restart based on process comparison provided by the present invention in conjunction with the accompanying drawings. Figure 1 , which shows a schematic diagram of the composition structure of a device for checking missing processes after system restart based on process comparison according to an embodiment of the present invention, the device 100 includes: a process collection module 101, a process comparison module 102 and an output module 103; wherein: The process acquisition module 101 is used to obtain target process information in the system.

[0031] Here, the process acquisition module can be implemented by a shell script. The system can be any type of server system. For example, the process information in the system is collected by a shell script before and after the server system is restarted to obtain the target process information in the server system. That is, the target process information includes: the first process information before the system is restarted and the second process information after the system is restarted. Among them, the first process information mainly includes the process control block (Process Control Block, PCB), program segment and data segment before the system is restarted; the second process information mainly includes the process control block (Process Control Block, PCB), program segment and data segment after the system is restarted. Among them, the process control block (PCB): is the core part of the process entity, which is used to describe the state of the process and control the operation of the process. The PCB contains all the information required by the operating system, which is used to describe the current status of the process and control the execution of the process. Program segment: is the program code segment in the process that can be executed by the process scheduler on the central processing unit. Data segment: includes the original data processed by the program corresponding to the process, as well as the intermediate or final data generated after the program is executed.

[0032] In some possible implementations, the process acquisition module 101 includes: an acquisition submodule and a determination submodule, wherein: the acquisition submodule is used to acquire the first process information before the system is restarted and the second process information after the system is restarted.

[0033] Here, the acquisition submodule collects the first process information before the system restart and the second process information after the system restart through the shell script. For example, the first process information before the system restart is collected through "function collect_pre_restart_processes() { ps -ef>pre_restart_processes.txt}" in the shell script code; the second process information after the system restart is collected through "function collect_post_restart_processes() { ps -ef>post_restart_processes.txt}" in the shell script code.

[0034] In some possible implementations, after acquiring the first process information, the acquisition submodule feeds back a restart instruction to the system so that the system restarts; and after the system restarts, the second process information is acquired. For example, after the acquisition submodule collects the first process information before the system restarts, it feeds back a restart instruction to the system so that the system restarts; and after receiving the restart information fed back by the system, the second process information of the system is acquired. In some possible implementations, the acquisition submodule first acquires the first preset command script, wherein the first preset command script may be a shell script; the shell script is pre-placed into a file with various commands, which is a program file that is convenient for one-time execution, and is mainly used to facilitate the administrator to set up or manage. Then, the acquisition submodule uses the first preset command script to collect the first process information before the system restarts and the second process information after the system restarts. In this way, the acquisition submodule can more accurately collect the first process information before the system restarts and the second process information after the system restarts.

[0035] The first determination submodule is used to determine the first process information and the second process information as the target process information. In this way, the acquisition submodule collects the first process information before the system restart and the second process information after the system restart, so as to obtain the target process information, so as to more accurately analyze the process difference information.

[0036] The process comparison module 102 is used to determine process difference information of the system before and after the restart based on the target process information.

[0037] Here, the process comparison module can be implemented by a comparison function. Since the target process information includes: the first process information before the system restarts and the second process information after the system restarts. The process difference information is used to characterize the difference between the process information before the system restarts and the process information after the system restarts, that is, the process difference information can reflect the process missing after the system restarts relative to before the restart. In some possible implementations, the process comparison module 102 compares the first process information and the second process information to obtain the process difference information of the system before and after the restart. For example, the process comparison module 102 first obtains the second preset command script, and uses the second preset command script to compare the first process information and the second process information to obtain the process difference information. Among them, the second preset command script can be a shell script, which is used to characterize the function of the comparison function, so as to realize the comparison of the first process information and the second process information, so as to analyze the difference between the process information before the system restarts and the process information after the system restarts, that is, to obtain more accurate process difference information, and then facilitate the analysis of process omission through the process difference information.

[0038] In some possible implementations, such as Figure 2 As shown, the process comparison module 102 includes: an extraction submodule 201 and a comparison submodule 202, wherein: The extraction submodule 201 is used to extract the process names in the first process information and the second process information by using the second preset command script to obtain the first name of the first process information and the second name of the second process information.

[0039] Here, the process names in the first process information and the second process information can be extracted through "awk '{print $8}' pre_restart_processes.txt>pre_restart_process_names.txt; awk '{print $8}' post_restart_processes.txt>post_restart_process_names.txt" in the second preset command script to obtain the first name and the second name.

[0040] The comparison submodule 202 is used to use the second preset command script to extract and compare the first name and the second name to obtain the process difference information.

[0041] Here, the first name and the second name can be compared through "comm -23 pre_restart_process_names.txt post_restart_process_names.txt>missing_processes.txt}" in the second preset command script to find out the missing process after the system is restarted, that is, to obtain the process difference information. In this way, the first name of the first process information and the second name of the second process information are extracted through the extraction submodule, so that by comparing the first name and the second name, the process difference information after and before the system restart can be efficiently and accurately analyzed.

[0042] The output module 103 is used to determine and output the process missing information of the system after restart based on the process difference information.

[0043] Here, since the process difference information can reflect the difference between the processes before and after the system restart, that is, the processes omitted after the system restart relative to before the system restart, the process difference information output module can output the process omission information of the system after the restart more clearly.

[0044] In some possible implementations, the output module 103 includes: a second determination submodule and a result output submodule, wherein: the second determination submodule is used to determine a preset output mode.

[0045] Here, the preset output mode may be a customized clear and easy-to-understand output mode, for example, the preset output mode may be a text mode, a voice mode, or an alarm mode.

[0046] The result output submodule is used to output the process missing information based on the preset output mode.

[0047] Here, the process missing information is output to the management end through a preset output method, so that the administrator can find the missing process in time.

[0048] In some possible implementations, such as Figure 3 As shown, the output module 103 may further include: an encapsulation submodule 301 and a capability output submodule 302, wherein: the encapsulation submodule 301 is used to encapsulate the process missing information to obtain encapsulated information; for example, the process missing information is encapsulated through the underlying encapsulation capability to obtain the encapsulated information.

[0049] The capability output submodule 302 is used to output the packaged information through an external interface. For example, by outputting the packaged information through an external interface, it is possible to connect to a general platform such as an operation and maintenance management platform to realize automatic checking of processes after automatic restart. In this way, through the encapsulation of the underlying capabilities, the server system users do not need to pay attention to the specific system version number, and can quickly confirm the location and confirm which processes of the server have not been successfully started; thereby realizing the automated management of large batches of servers without having to pay attention to the actual business situation of a single machine one by one.

[0050] In the embodiment of the present invention, the target process information in the system is obtained through the process acquisition module, and then the process comparison module determines the process difference information of the system before and after the restart based on the target process information; in this way, the difference between the processes of the system before and after the restart can be more accurately indicated through the process difference information. Finally, the output module determines and outputs the process omission information of the system after the restart based on the process difference information; in this way, the process omission information of the system after the restart can be quickly and automatically output through the output module, and no manual intervention is required, thereby saving labor costs, thereby improving the efficiency and accuracy of detecting the missing process after the system restarts.

[0051] The embodiment of the present invention provides a method for checking missing processes after system restart based on process comparison. Figure 4, which shows a schematic diagram of an implementation flow of a method for checking missing processes after system restart based on a process comparison method provided by an embodiment of the present invention, the method comprising: 401, obtain target process information in the system.

[0052] Here, the target process information includes: the first process information before the system restart and the second process information after the system restart. The first process information before the system restart is obtained by executing a shell command script or calling a system interface to obtain a process list; then, the system is restarted. The process list after the system restart is obtained by performing the same operation, that is, the second process information after the system restart is obtained. The first process information and the second process information are determined as the target process information.

[0053] In some possible implementations, a first preset command script is first obtained; and the first preset command script is used to collect first process information before the system is restarted and second process information after the system is restarted.

[0054] 402 : Determine process difference information of the system before and after the restart based on the target process information.

[0055] Here, through the comparison function, the names of the first process information and the second process information in the target process information are compared to obtain the difference between the system before and after restart, that is, the process difference information, so that the process missed by the system after restart can be reflected through the process difference information.

[0056] In some possible implementations, a second preset command script is obtained; and the second preset command script is used to compare the first process information and the second process information to obtain process difference information. For example, the second preset command script is used to extract the process names in the first process information and the second process information to obtain a first name of the first process information and a second name of the second process information; and the first name and the second name are compared to obtain process difference information.

[0057] 403 : Based on the process difference information, determine and output process missing information of the system after restart.

[0058] Here, through the process omission situation of the system after restart represented by the process difference information, the process omission information can be encapsulated and the encapsulated information can be output to facilitate docking with general platforms such as operation and maintenance management platforms to realize automatic process inspection after automatic restart, thereby improving the accuracy of checking process omissions.

[0059] In some possible implementations, a preset output mode may be determined; and the process missing information is outputted using the preset output mode.
