Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a memory control method, device, equipment and storage medium. Background Art

[0002] The browser / server model (B / S) leverages maturing web browser technology to implement powerful features that previously required specialized software, saving development costs. Existing mass storage management software, based on a B / S architecture, enables user-friendly interface management of storage systems, allowing users to manage storage resources through user interfaces. Furthermore, in addition to managing the storage system through a web interface, existing mass storage management software also utilizes independent backend modules for support. Consequently, memory leaks in management software modules can occasionally occur during long-term operation of storage systems.

[0003] Existing memory control techniques utilize Cgroups (control groups), a feature of the Linux kernel. This involves grouping modules into process groups and setting a memory usage cap. Once the memory usage of a module in a process group reaches the cap, the process with the largest memory usage is killed and restarted. However, restarting processes doesn't effectively control the time it takes to restart, and only the process with the largest memory usage can be restarted. This can cause further issues for modules with rapidly growing memory usage. Furthermore, directly restarting module processes can cause business interruptions. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] Prior art uses a Linux kernel feature called Cgroup for memory control. This involves dividing modules into process groups and setting a memory usage cap. Once the memory used by a module in a process group reaches the cap, the process with the largest memory usage is killed and restarted. However, restarting processes doesn't effectively control the time it takes to restart, and can only restart the process with the largest memory usage. This can cause further problems for modules with rapidly growing memory usage. To overcome these technical issues, this application proposes a memory control method that enables automatic memory control.

[0044] The present application discloses a memory control method. Figure 1 As shown, the method may include the following steps:

[0045] Step S11: Allocate a memory upper limit for each process module in the storage system.

[0046] In this embodiment, a memory cap is first assigned to each process module in the storage system. This cap must ensure that the total memory cap does not exceed the remaining system memory. Based on experience, specific memory cap thresholds can be assigned to different process modules. For example, a memory cap (a1, a2, ..., an) is assigned to each process module (A1, A2, ..., An), with the total memory cap being am = a1 + a2 + ... + an, where am does not exceed the remaining system memory M.

[0047] In this embodiment, before allocating a memory limit for each process module in the storage system, the following steps may be included: adding a corresponding event manager to the storage system and obtaining instructions through the event manager; determining all associated process modules corresponding to the instruction and detecting the operating status of the associated process modules; issuing the instruction if the operating status of all associated process modules is normal; otherwise, caching the instruction until the operating status of all associated process modules is normal, at which point the instruction is issued. That is, by adding an event manager to the storage system, all issued instructions are issued through the event manager; upon receiving the instruction, the event manager identifies all modules that the instruction depends on and checks whether all dependent module processes are normal. If they are normal, the instruction is issued directly; otherwise, the instruction is cached and waits for the next detection cycle until normal again before issuing the instruction. Thus, by utilizing the event manager's caching function, instructions are issued only after the modules are normal, thus avoiding service interruptions caused by a process restart. Furthermore, the memory control method disclosed in this embodiment can also be executed by the aforementioned event manager.

[0048] Step S12: periodically obtaining the actual used memory corresponding to the process module according to a preset time interval, and screening out the process modules whose actual used memory is greater than the memory upper limit as target process modules.

[0049] In this embodiment, after the system is operational, the actual memory usage corresponding to the process modules is periodically obtained at preset intervals, and process modules whose actual memory usage exceeds the upper memory limit are selected as target process modules. Specifically, the memory usage status of the process modules is detected according to the detection period to select process modules whose actual memory usage exceeds the upper memory limit as target process modules, facilitating subsequent adjustment of the upper memory limit for these target process modules. Specifically, the actual memory usage (b1, b2, ..., bn) of each process module (A1, A2, ..., An) is queried, and the target process module An is selected to determine if its memory usage bn exceeds the upper memory limit an.

[0050] In this embodiment, after selecting process modules whose actual memory usage exceeds the memory limit as target process modules, the method may further include recording the target instruction set associated with the target process module in an exception list corresponding to the target process module, and generating a detection report based on the exception list. Specifically, during each detection cycle, the instruction set of each target process module with memory anomalies is recorded, and an exception data report is output to facilitate recording and troubleshooting the cause of the memory anomaly.

[0051] Step S13: determining a memory upper limit adjustment method, and increasing the memory upper limit of the target process module according to the memory upper limit adjustment method.

[0052] In this embodiment, after determining the target process module with memory abnormality, the memory upper limit adjustment method corresponding to the target process module is first determined, and then the memory upper limit of the target process module is increased according to the memory upper limit adjustment method to restore the memory to normal operation.

[0053] In this embodiment, determining a memory upper limit adjustment method and increasing the memory upper limit of the target process module according to the memory upper limit adjustment method may include: calculating the remaining memory of the process modules other than the target process module; the remaining memory amount is the difference between the memory upper limit and the actual memory usage; determining a memory upper limit adjustment method based on the remaining memory amount and a screening condition, and increasing the memory upper limit of the target process module according to the memory upper limit adjustment method; the screening condition is a condition determined based on the actual memory usage of the target process module and a preset percentage. Calculating the remaining memory of the remaining process modules, such as the difference ci between the memory upper limit ai and the actual memory bi of process Ai, ci = ai - bi; then determining a memory upper limit adjustment method based on the remaining memory amount and the screening condition, and increasing the memory upper limit of the target process module according to the memory upper limit adjustment method, wherein the screening condition is a condition determined based on the actual memory usage of the target process module and a preset percentage.

[0054] In this embodiment, determining a memory upper limit adjustment method based on the remaining memory and a screening condition, and increasing the memory upper limit of the target process module according to the memory upper limit adjustment method may include: calculating a screening threshold based on the screening condition; if a process module exists whose remaining memory is greater than the screening threshold, treating the process module as a partially occupied process module; lowering the memory upper limit of the partially occupied process module by a preset downward adjustment amount to obtain free memory, and allocating the free memory to the target process module to increase the memory upper limit of the target process module. For example, if the preset percentage is 30% and the actual used memory of the target process module An is bn, the screening threshold is bn*30%. Further, determining whether there is a process Ai whose actual memory bi differs from the threshold ai by ci>=bn*30%; if so, adjusting Ai's memory upper limit to ai=ai*80% according to a preset downward adjustment amount, such as 80%, and simultaneously allocating ai*20% to an. After adjustment, an=an+ai*20%, and then entering the next detection cycle.

[0055] In this embodiment, determining a memory upper limit adjustment method based on the remaining memory and preset screening conditions, and increasing the memory upper limit of the target process module according to the memory upper limit adjustment method may include: calculating a screening threshold based on the screening conditions, and if no process module has a remaining memory greater than the screening threshold, directly increasing the memory upper limit of the target process module according to a preset increase. That is, if no process module has a remaining memory greater than the screening threshold, directly increasing the memory upper limit of the target process module according to a preset increase, such as 120%. After adjustment, the memory upper limit of the target process module is an = an * 120%. In other words, internal thresholds are reallocated. If internal allocation is impossible, the thresholds are directly increased. When insufficient memory occurs, some target process modules that exceed the threshold are restarted.

[0056] By monitoring memory usage in each module in real time and appropriately allocating memory usage limits for each module, the system restarts the offending module to free up memory if a memory anomaly impacts system memory usage. This also allows the event manager to cache instructions without disrupting normal storage operations. The preset percentages, decreases, and increases are customizable based on historical data and cluster size.

[0057] In this embodiment, if no process module has a remaining memory amount greater than the screening threshold, then directly increasing the memory limit of the target process module according to a preset increase, the process may further include: determining whether the total memory limit of the storage system is greater than the remaining memory of the storage system based on the adjusted memory limit of the target process module; if so, restarting the target process module and adjusting the memory limit of the target process module back to the most recent historical memory limit. That is, if increasing the threshold an would cause the total memory am to exceed the remaining memory M of the entire system, the process is restarted and the memory threshold is still adjusted back to an.

[0058] As can be seen from the above, in this embodiment, a memory upper limit is allocated to each process module in the storage system; the actual memory usage corresponding to the process module is periodically obtained according to a preset time interval, and the process modules whose actual memory usage is greater than the memory upper limit are screened out as target process modules; a memory upper limit adjustment method is determined, and the memory upper limit of the target process module is increased according to the memory upper limit adjustment method. It can be seen that by allocating a memory usage upper limit threshold to each process module, the usage of each memory is detected in each detection cycle, and the memory upper limit is adjusted if the memory usage exceeds the upper limit. Thus, by real-time detection of the memory usage of all process modules and reallocation of the memory upper limit of the target process module in real time in each detection cycle, automatic memory control is achieved without affecting the business, minimizing the probability of memory anomalies in the entire system, and enhancing the robustness of the system.

[0059] This embodiment also discloses a specific schematic diagram of the implementation process of the storage management software memory control method, such as Figure 2 and Figure 3 The specific implementation process is as follows:

[0060] (1) Add an event manager to the storage system, and all instructions are issued through the event manager;

[0061] (2) After receiving the instruction, the event manager identifies the modules that the instruction depends on and checks whether all dependent module processes are normal. If they are normal, the instruction is issued directly; otherwise, step (3) is executed;

[0062] (3) Store the instruction in the cache and wait for the next detection cycle until it is normal before issuing the instruction again;

[0063] (4) Allocate a memory limit (a1, a2, ..., an) to each process module (A1, A2, ..., An). The total memory limit is am = a1 + a2 + ... + an, and am does not exceed the remaining memory M of the entire system.

[0064] (5) Query the actual memory used (b1, b2, …, bn) of each process module (A1, A2, …, An);

[0065] (6) If the memory bn used by module An exceeds the threshold an, then execute step (7).

[0066] (7) Compare the actual memory used by other processes with the memory upper limit, and determine whether there is a process Ai whose actual memory bi and the threshold ai have a difference ci that satisfies ci>=bn*30%. If the condition is met, execute step (8), otherwise execute step (9);

[0067] (8) Adjust the Ai memory limit to ai = ai * 80%, and allocate ai * 20% to an (an = an + ai * 20%), execute step (5), and enter the next detection cycle;

[0068] (9) Directly increase the threshold an=an*120% and execute step (10);

[0069] (10) If increasing the threshold an causes the total memory am to exceed the remaining memory M of the entire system, the process is restarted and the memory threshold is still adjusted back to an. Execute step (11);

[0070] (11) Record the set of instructions that depend on the An process during the detection period into the An memory anomaly list and output a detection report;

[0071] It can be seen that by assigning a memory upper limit to each process module, the actual memory usage of each module is recorded in each detection cycle and compared with the memory upper limit threshold. When a module memory exceeds the threshold, the difference between the memory usage of other modules and the threshold is detected, and the upper limit value with a larger threshold difference is adjusted down, while the memory upper limit of the module exceeding the memory threshold is increased. If the difference between the memory usage of all modules and the threshold does not meet the allocation requirements, the memory upper limit of the module exceeding the memory threshold is directly increased. If the total memory exceeds the remaining memory of the system, the module is restarted. At the same time, the instruction set of each module with memory abnormality is recorded in each detection cycle, and an abnormal data report is output to record and troubleshoot the cause of the memory abnormality. In this way, automatic memory control is achieved without affecting business and enhancing the robustness of the system.

[0072] Correspondingly, the embodiment of the present application also discloses a memory control device, see Figure 4 As shown, the device includes:

[0073] A memory allocation module 11 is used to allocate a memory upper limit for each process module in the storage system;

[0075] The memory adjustment module 13 is configured to determine a memory upper limit adjustment method and increase the memory upper limit of the target process module according to the memory upper limit adjustment method.

[0076] As can be seen from the above, in this embodiment, a memory upper limit is allocated to each process module in the storage system; the actual memory usage corresponding to the process module is periodically obtained according to a preset time interval, and the process modules whose actual memory usage is greater than the memory upper limit are screened out as target process modules; a memory upper limit adjustment method is determined, and the memory upper limit of the target process module is increased according to the memory upper limit adjustment method. It can be seen that by allocating a memory usage upper limit threshold to each process module, the usage of each memory is detected in each detection cycle, and the memory upper limit is adjusted if the memory usage exceeds the upper limit. Thus, by real-time detection of the memory usage of all process modules and reallocation of the memory upper limit of the target process module in real time in each detection cycle, automatic memory control is achieved without affecting the business, minimizing the probability of memory anomalies in the entire system, and enhancing the robustness of the system.
