Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically, to a method, apparatus, and electronic device for processing input / output information. Background Technology

[0002] With the rapid development of computer technology, distributed storage systems are placing increasingly higher demands on storage performance. Performance tuning is an essential step in improving storage performance. Performance tuning involves monitoring and analyzing operational data reflecting system performance, such as system response speed, to identify performance bottlenecks. Among these, the I / O (In / Output) path and its related information implicitly reveal various aspects of the storage device's performance and serve as crucial data for software tuning. Analyzing the I / O path and its associated information can pinpoint potential or existing problems within the storage device.

[0003] Currently, existing technologies for monitoring I / O paths and related information in distributed storage systems cannot specify block devices for tracking. Instead, all block device I / O paths and related information are written to a circular buffer, significantly impacting system performance and resulting in low system performance. Furthermore, because existing technologies cannot detect write activity to the circular buffer, data overwriting is possible, easily leading to the loss of I / O paths and related information.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0007] Furthermore, the method for processing input / output information also includes: setting the tracking position of I / O information in the program script of the target application, and adding a field containing the target block device name to the tracking position.

[0008] Furthermore, the input / output information processing method also includes: obtaining the current value of the target variable, wherein the target variable is used to record the remaining capacity of the circular buffer, and the remaining capacity corresponds to the value of the target variable; calculating the difference between the current value of the target variable and the value corresponding to the first storage capacity to obtain the target difference; determining the target capacity of the circular buffer based on the target difference; updating the target variable based on the target capacity, and using the circular buffer corresponding to the target capacity as the remaining circular buffer.

[0009] Furthermore, the method for processing input / output information also includes: generating a prompt message when the first storage capacity is greater than the remaining capacity, wherein the prompt message is used to indicate that the target object I / O information writing has failed.

[0010] Furthermore, the input / output information processing method also includes: when the I / O information meets preset conditions, exporting the I / O information written by the target block device from the circular buffer corresponding to the first storage capacity.

[0011] Furthermore, the input / output information processing method also includes: obtaining the delay time for the distributed system to process I / O requests, wherein the delay time is the time interval between the time of the last I / O request processing and the time of the current I / O request processing; obtaining the keyword corresponding to the I / O completion time, and parsing the keyword to obtain the I / O completion time, wherein the I / O completion time is the time interval between the time the target block device writes I / O information and the time of exporting I / O information; and generating I / O request processing information based on the delay time and the I / O completion time.

[0012] According to another aspect of the present invention, an input / output information processing apparatus is also provided, comprising: a receiving module, configured to receive an input / output I / O information write request sent by a target application, wherein the I / O information write request includes at least a target block device name and a first storage capacity, wherein the first storage capacity is the capacity required by the block device to write I / O information into a circular buffer, and the circular buffer is used to store the written I / O information; a comparison module, configured to compare the first storage capacity with the remaining capacity of the circular buffer; a determining module, configured to determine a target block device corresponding to the target block device name from a plurality of block devices if the first storage capacity is less than or equal to the remaining capacity; and a processing module, configured to write the I / O information into the circular buffer corresponding to the first storage capacity based on the target block device.

[0013] According to another aspect of the present invention, a computer program product is also provided, including a computer program / instructions that, when executed by a processor, implement the above-described input / output information processing method.

[0014] According to another aspect of the present invention, a computer-readable storage medium is also provided, wherein a computer program is stored in the computer program, wherein the computer program is configured to execute the above-described input / output information processing method at runtime.

[0015] According to another aspect of the present invention, an electronic device is also provided, the electronic device including one or more processors; a memory for storing one or more programs, wherein when the one or more programs are executed by the one or more processors, the one or more processors implement the one or more processors for running the programs, wherein the programs are configured to execute the above-described input / output information processing method during runtime.

[0016] In this embodiment of the invention, a method is adopted whereby a target block device that is allowed to be written to the circular buffer is specified. First, an input / output (I / O) information write request sent by the target application is received. Then, a first storage capacity is compared with the remaining capacity of the circular buffer. If the first storage capacity is less than or equal to the remaining capacity, a target block device corresponding to the target block device name is determined from multiple block devices. Then, based on the target block device, the I / O information is written to the circular buffer corresponding to the first storage capacity. The I / O information write request includes at least the target block device name and the first storage capacity, where the first storage capacity is the capacity required by the block device to write the I / O information to the circular buffer, and the circular buffer is used to store the written I / O information.

[0017] In the above process, by comparing the first storage capacity with the remaining capacity of the circular buffer, the current usage of the circular buffer can be clearly identified, thereby avoiding data overwriting and the loss of I / O information. By determining the target block device corresponding to the target block device name, the block device to be written to the circular buffer is specified, avoiding the overall system degradation caused by writing a large amount of I / O information to block devices, and reducing the impact on the overall system performance.

[0018] Therefore, the technical solution of this invention achieves the goal of monitoring the I / O path and related information of the distributed storage system through the target block device, thereby reducing the impact on system performance. It also solves the technical problem in the prior art that the I / O information of all block devices is written into the circular buffer because the I / O information of the block device that needs to be written into the circular buffer cannot be distinguished, resulting in low performance of the storage system.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0031] It should be noted that all relevant information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data used for analysis, etc.) involved in this invention are information and data authorized by the user or fully authorized by all parties. For example, this system has an interface with the relevant user or organization. Before obtaining relevant information, it needs to send an acquisition request to the aforementioned user or organization through the interface, and obtain the relevant information after receiving consent from the aforementioned user or organization.

[0032] Example 1

[0033] According to an embodiment of the present invention, a method embodiment for processing input / output information is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0034] Figure 1 This is a flowchart of an optional input / output information processing method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0035] Step S101: Receive an input / output (I / O) information write request sent by the target application. The I / O information write request includes at least the target block device name and a first storage capacity. The first storage capacity is the capacity required for the block device to write the I / O information into the circular buffer. The circular buffer is used to store the written I / O information.

[0036] In the above steps, the target application can be the application SPDK APPS that comes with the high-performance storage development component SPDK, and the I / O information can be I / O path tracing information of system calls such as I / O name, type, and size. A circular buffer is a computer memory area used to store input information. Its space size is fixed. When the circular buffer is full, it will overwrite the first element stored in the circular buffer.

[0037] Specifically, existing technologies typically use tracing tools like blktrace to trace I / O activities in the kernel space (kernel mode) of a storage system. However, for current high-performance distributed storage systems, since I / O activities occur in user space (user mode), existing technologies cannot meet the I / O path tracing requirements of distributed storage systems. It should be noted that the aforementioned high-performance storage development component SPDK runs in user space (user mode). Therefore, this invention uses the aforementioned high-performance storage development component SPDK to monitor I / O paths and related information in a distributed storage system.

[0038] Step S102: Compare the first storage capacity with the remaining capacity of the circular buffer.

[0039] Step S103: If the first storage capacity is less than or equal to the remaining capacity, determine the target block device corresponding to the target block device name from multiple block devices.

[0040] In the above steps, the target block device is a block device that allows write operations. For example, when writing I / O information to a circular buffer, there are multiple block devices named I / O Device0, I / O Device1, I / O Device2, I / O Device3, etc., which are respectively bound to multiple CPU cores named Core0, Core1, Core2, Core3, etc. Assuming that the target block device name in the I / O information write request in the aforementioned process is I / O Device0, then the block device corresponding to I / O Device0 can be used as the target block device, and the write operation can be performed through Core0.

[0041] Step S104: Based on the target block device, write the I / O information into the circular buffer corresponding to the first storage capacity.

[0042] In the above steps, using a specified target block device to write I / O information to the circular buffer reduces the amount of unnecessary I / O information writing and minimizes the impact on system performance. For example, the first storage capacity can be 1GB. In this case, the circular buffer corresponding to the first storage capacity is 1GB of space within the circular buffer. After determining the block device corresponding to I / O Device0 as the target block device in the aforementioned process, I / O information can be written to the 1GB of space in the circular buffer through Core0, which is bound to the target block device, i.e., the block device corresponding to I / O Device0.

[0043] Based on the scheme defined in steps S101 to S104 above, it can be understood that in this embodiment of the invention, by specifying a target block device that is allowed to be written to the circular buffer, the input / output (I / O) information write request sent by the target application is first received. Then, the first storage capacity is compared with the remaining capacity of the circular buffer. If the first storage capacity is less than or equal to the remaining capacity, the target block device corresponding to the target block device name is determined from multiple block devices. Then, based on the target block device, the I / O information is written to the circular buffer corresponding to the first storage capacity. The I / O information write request includes at least the target block device name and the first storage capacity, where the first storage capacity is the capacity required by the block device to write the I / O information to the circular buffer, and the circular buffer is used to store the written I / O information.

[0044] It is noteworthy that, in the above process, by comparing the first storage capacity with the remaining capacity of the circular buffer, the current usage of the circular buffer can be clearly identified, thereby avoiding data overwriting and the loss of I / O information. By determining the target block device corresponding to the target block device name, the block device to be written to the circular buffer is specified, avoiding the overall system degradation caused by writing a large amount of I / O information to block devices, and reducing the impact on the overall system performance.

[0045] Therefore, the technical solution of this invention achieves the goal of monitoring the I / O path and related information of the distributed storage system through the target block device, thereby reducing the impact on system performance. It also solves the technical problem in the prior art that the I / O information of all block devices is written into the circular buffer because the I / O information of the block device that needs to be written into the circular buffer cannot be distinguished, resulting in low performance of the storage system.

[0046] In one alternative embodiment, before receiving an input / output I / O information write request sent by the target application, the tracking position of the I / O information is set in the program script of the target application, and a field containing the target block device name is added to the tracking position.

[0047] Optionally, based on the high-performance storage development component SPDK running in user space, the selected block devices are filtered to write I / O information to the circular buffer, reducing the impact on system performance. Specifically, SPDK APPS applications limit the CPUs used during program initialization, and each CPU runs a thread bound to it. These threads, called Reactors, are responsible for handling actual business logic within SPDK. Each Reactor is bound not only to a CPU but also to the block device handling I / O. During I / O path tracing, the block device writes I / O information to the circular buffer through the Reactor. However, because it's impossible to distinguish which block devices' I / O information needs to be written to the circular buffer, with a large number of block devices, writing a large amount of I / O information to the circular buffer can lead to a decrease in overall system performance. For example, ... Figure 2 As shown, Core0 is the CPU core bound to the target block device I / O Device0, and Reactor on Core0 is the thread bound to CPU core Core0.

[0048] Optionally, to address the above issues, before receiving the input / output (I / O) information write request from the target application, the I / O information tracking position (i.e., the I / O tracking point) can be set in the SPDK APPS program script. A block device name field can be added to the I / O tracking point, allowing the Reactor to carry the target block device name. This enables writing of I / O information to the circular buffer only to the target block device corresponding to the block device name, filtering out threads for block devices with mismatched names and reducing the impact on overall system performance. For example, ... Figure 3 As shown, if block device I / O Device0 is not added in the program script, Core0 bound to I / O Device0 will not perform write operations. That is, when writing I / O information to the circular buffer, Reactor on Core0 is filtered out and cannot write to the circular buffer.

[0049] In one optional embodiment, after receiving an input / output (I / O) information write request from the target application, the current value of the target variable is obtained. Then, the difference between the current value of the target variable and the value corresponding to the first storage capacity is calculated to obtain the target difference. Based on the target difference, the target capacity of the circular buffer is determined. Then, the target variable is updated based on the target capacity, and the circular buffer corresponding to the target capacity is used as the remaining circular buffer. The target variable is used to record the remaining capacity of the circular buffer, and the remaining capacity corresponds to the value of the target variable.

[0050] Specifically, in SPDK applications, the circular buffer is prone to overwriting when IOPS (Input / Output Operations Per Second) is high. Although the application provides tools to copy data from the buffer to the system disk, the circular buffer resides in memory, resulting in faster write speeds compared to the system disk. When the write speeds of the system disk and the buffer differ significantly, users cannot determine if overwriting has occurred and must check I / O path tracing information to ascertain whether previous information has been overwritten. For example, ... Figure 4 As shown, I / O path tracing information 11 covers I / O path tracing information 01.

[0051] Optionally, to solve the above problems, such as Figure 5 As shown, in the SPDK application's spdk trace initialization script, a global variable `g_trace_size`, the target variable, is created to record the size of the remaining circular buffer, i.e., the total size of the current circular buffer. The size of the circular buffer can be set by the administrator based on different IOPS values. Further, when SPDK writes I / O path trace information using the circular buffer, it allocates a certain size of I / O trace memory space (trace buffer), i.e., the first storage capacity, from the circular buffer for writing new I / O path trace information. Further, the difference between the global variable `g_trace_size` and the allocated I / O trace memory space is calculated to obtain the target difference. Therefore, the current size of the circular buffer, i.e., the target capacity, can be determined from the target difference. Further, the global variable `g_trace_size` is updated, and the value of the global variable `g_trace_size`, i.e., the current size of the circular buffer, is returned through the API function `get_trace_size()`, thus indicating the used circular buffer space.

[0052] In one alternative embodiment, after comparing the first storage capacity with the remaining capacity of the circular buffer, if the first storage capacity is greater than the remaining capacity, a prompt message is generated, wherein the prompt message is used to indicate that the target object I / O information writing has failed.

[0053] Optionally, in this invention, the API function `get_trace_size()` can be used to control whether overwrite is allowed. Specifically, if the requested size of the circular buffer is greater than the remaining size, writing is prohibited until the previously written I / O information is retrieved, and the requested size of the circular buffer is less than or equal to the remaining size. Simultaneously, a prompt message is generated to inform the administrator that the write buffer failed due to the prohibition of overwrite. It should be noted that whether overwrite is allowed can be set by the administrator according to their needs; this invention does not impose any limitations.

[0054] In one optional embodiment, after writing I / O information to a circular buffer corresponding to a first storage capacity based on the target block device, the I / O information written by the target block device is exported from the circular buffer corresponding to the first storage capacity if the I / O information meets preset conditions. Optionally, the preset conditions may be, for example, reaching a target time, which can be set by the administrator according to needs, and this invention is not limited thereto.

[0055] In one optional embodiment, after writing I / O information to a circular buffer corresponding to the first storage capacity based on the target block device, the latency time for the distributed system to process the I / O request is obtained, a keyword corresponding to the I / O completion time is obtained, and the keyword is parsed to obtain the I / O completion time. Then, based on the latency time and the I / O completion time, I / O request processing information is generated. Here, the latency time is the time interval between the time of the previous I / O request processing and the time of the current I / O request processing, and the I / O completion time is the time interval between the time the target block device writes the I / O information and the time the I / O information is exported.

[0056] Optionally, the processed information can be displayed in the form of graphics, tables, etc., which can be set by the administrators according to their needs. This invention does not impose any limitations.

[0057] Optionally, this invention uses an I / O latency frequency histogram as an example. In existing technologies, when using the blktrace tool to trace the path of I / O activities in the kernel space of a storage system, the I / O completion time cannot be directly obtained. That is, in existing technologies, an additional blkparse tool is needed to parse the file generated by blktrace, and then the btt tool is used to draw the I / O latency frequency histogram. blkparse is a tool that obtains the output file of blktrace and converts its information into human-understandable text information, while btt is a tool that obtains data from blkparse and draws the I / O latency frequency histogram by analyzing the data. Furthermore, blkparse depends on the output of blktrace, and btt depends on the output of blkparse, forming a closed dependency relationship, making it impossible to draw a user-space I / O latency frequency histogram.

[0058] Optionally, to address the above issue, the SPDK records the I / O activity time. Specifically, before I / O submission, the I / O trace point registration start time is recorded; after I / O processing is completed, the I / O trace point registration end time is recorded. Then, the completion time is calculated based on the start and end times, directly providing the I / O completion time. Optionally, Figure 6 This is a schematic diagram of optional I / O path tracing information according to an embodiment of the present invention, such as... Figure 6 As shown, the value corresponding to the keyword "time" is the I / O completion time. For example, in "time: 1310.432", 1310.432 is the I / O completion time.

[0059] Furthermore, such as Figure 7 As shown, using latency (delay time) as the horizontal axis, the keyword "time" is read and its corresponding value is parsed and stored in the array `latancy`. Then, the frequency of time elements appearing in the `latancy` array is counted to plot an I / O latency frequency histogram, as shown below. Figure 8 As shown.

[0060] Therefore, the technical solution of this invention achieves the goal of monitoring the I / O path and related information of the distributed storage system through the target block device, thereby reducing the impact on system performance. It also solves the technical problem in the prior art that the I / O information of all block devices is written into the circular buffer because the I / O information of the block device that needs to be written into the circular buffer cannot be distinguished, resulting in low performance of the storage system.
