[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0057] The read / write performance indicator (Input / Output Operations Per Second, IOPS) refers to the number of read / write (I / O) operations per second, and is one of the main indicators for measuring disk performance.
[0058] See also Figure 1 , which is a flow chart of an embodiment of a performance monitoring method for a virtual disk provided by the present application. The method is applied to a host machine, a virtual machine is running on the host machine, and the virtual machine includes a virtualization front-end system, including:
[0059] S101: Run a virtual disk monitoring program to obtain disk capacity data of a virtual disk in a virtual machine.
[0060] In this embodiment, by running a virtual disk monitoring program on the host machine, the disk capacity data of the virtual disk in the virtual machine is monitored to obtain the disk capacity usage of the virtual disk, which may include the total capacity of the virtual disk, the used disk capacity and the available disk capacity.
[0061] S102: In response to the write operation of the virtual machine, the monitor program in the virtualization front-end system determines the write performance data of the virtual disk based on the amount of write data in the write cache.
[0062] Among them, write performance data includes write rate and write performance index
[0063] In this embodiment, in response to a write operation generated in a virtual machine, a first counter is created by running a first monitoring program in a virtualization front-end system to count the write data in the write cache, thereby obtaining the total number of write data and a first counting time, and calculating the write rate based on the first counting time and the total number of write data. At the same time, a second counter is created to count the number of times the write data is written into the cache, thereby obtaining the number of writes and a second counting time, and calculating the write IOPS based on the second counting time and the number of writes.
[0064] S103: In response to the read operation of the virtual machine, the monitoring program determines the read performance data of the virtual disk based on the amount of read data read from the cache.
[0065] The read performance data includes the read rate and the read performance index.
[0066] In this embodiment, in response to a read operation generated in the virtual machine, a third counter is created by running a first monitoring program in the virtualization front-end system to count the read data read from the cache, thereby obtaining the total number of read data and a third counting time, and calculating the read rate based on the third counting time and the total number of read data. At the same time, a fourth counter is created to count the number of times data is read from the cache, obtaining the number of reads and a fourth counting time, and calculating the read IOPS based on the counting time of the fourth counting time and the number of reads.
[0067] In this embodiment, by running a virtual disk monitoring program, the disk capacity data of the virtual disk in the virtual machine is obtained to monitor the disk capacity usage of the virtual disk. When a write operation occurs, in response to the write operation of the virtual machine, the amount of write data in the write cache is monitored through the monitoring program in the virtualization front-end system, and then the write performance data of the virtual disk is determined to achieve write performance monitoring of the virtual disk; when a read operation occurs, in response to the read operation of the virtual machine, the amount of read data read from the cache is monitored through the monitoring program, and then the read performance data of the virtual disk is determined to achieve read performance monitoring of the virtual disk. Compared with the prior art, the method of the present application improves the accuracy of virtual disk performance monitoring by comprehensively monitoring the disk capacity usage and the write and read performance of the virtual disk.
[0068] See also Figure 2 , which is a flow chart of another embodiment of a virtual disk performance monitoring method provided by the present application. Figure 1 , Figure 2 A specific implementation method of S102 "determining the write performance data of the virtual disk based on the amount of write data in the write cache by a monitoring program in the virtualization front-end system in response to the write operation of the virtual machine" is shown, specifically in combination with Figure 2 S1021-S1024 are introduced in.
[0069] S1021: In response to the write operation of the virtual machine, run a first monitoring program to count the amount of written data in the write cache through a first counter to obtain a total amount of written data and a first counting time.
[0070] In this embodiment, in response to the write operation of the virtual machine, the first monitoring program running in the virtual machine creates a first counter, and uses the first counter to count the amount of write data written into the cache corresponding to the write operation to obtain the total amount of write data and the first counting time.
[0071] It is understandable that when a write operation is generated in a virtual machine, the write data corresponding to the write operation is first sent to the cache of the virtualization front-end system and then transmitted to the virtualization back-end system through a shared memory. At the same time, in response to a data receiving request sent by the virtualization front-end system, the virtualization back-end system takes the write data from the cache and writes it to the virtual disk.
[0072] S1022: Run the first monitoring program to count the number of times the write data is written into the cache by using the second counter to obtain the number of writes and a second counting time.
[0073] In this embodiment, the first monitoring program running in the virtual machine creates a second counter, and uses the second counter to count the number of times the write data corresponding to the write operation is written into the cache to obtain the number of writes and the second counting time.
[0074] S1023: Calculate the write rate of the virtual disk based on the first counting time and the total amount of written data.
[0075] In this embodiment, based on the first counting time corresponding to the first timer and the total amount of written data, the amount of data written by the virtual disk within a unit time, ie, the write rate of the virtual disk, is calculated.
[0076] S1024: Calculate a write performance index of the virtual disk based on the second counting time and the number of writes.
[0077] In this embodiment, based on the counting time of the second counting time corresponding to the second timer and the number of write operations, the number of write operations completed by the virtual disk within a unit time, ie, the write IOPS of the virtual disk, is calculated.
[0078] In this embodiment, in response to the write operation of the virtual machine, the first monitoring program counts the amount of write data in the write cache through the first counter to obtain the total amount of write data and the first counting time, and can monitor the data write activity of the virtual disk in real time; counts the number of times the write data is written to the cache through the second counter to obtain the number of writes and the second counting time; based on the first counting time and the total amount of write data, the write rate of the virtual disk is calculated; based on the second counting time and the number of writes, the write performance index of the virtual disk is calculated, so as to realize the monitoring of the write performance of the virtual disk and improve the accuracy of the monitoring of the virtual disk.
[0079] Combination Figure 2 As shown, before executing S1021-S1024, refer to the previous embodiment and execute S101 to realize the disk capacity data of the virtual disk; after executing S1021-S1024, refer to the previous embodiment and execute S103 to realize the acquisition of the read performance data of the virtual disk.
[0080] See also Figure 3 , which is a flow chart of another embodiment of a virtual disk performance monitoring method provided by the present application. Figure 1 , Figure 3 A specific implementation method of S103 "determining the read performance data of the virtual disk based on the amount of read data read from the cache by a monitoring program in the virtualization front-end system in response to the write operation of the virtual machine" is shown, specifically in combination with Figure 3 S1031-S1034 are introduced in.
[0081] S1031: In response to a read operation of the virtual machine, a first monitoring program is run to count the amount of read data read from the cache by a third counter to obtain a total amount of read data and a third counting time.
[0082] In this embodiment, in response to the read operation of the virtual machine, the first monitoring program running in the virtual machine creates a third counter, and uses the third counter to count the amount of read data read from the cache to obtain the total amount of read data and the third counting time.
[0083] It is understandable that when a read operation occurs in a virtual machine, the virtual backend system writes the read data into the cache and transmits it to the virtualized frontend system via shared memory, and then the virtualized frontend system retrieves the read data from the cache.
[0084] S1032: Run the first monitoring program to count the number of times data is read from the cache using a fourth counter to obtain the number of reads and a fourth counting time.
[0085] In this embodiment, the first monitoring program running in the virtual machine creates a fourth timer, and uses the fourth timer to count the number of times data is read from the cache to obtain the number of times and a fourth counting time.
[0086] S1033: Calculate the read rate of the virtual disk based on the third counting time and the total amount of read data.
[0087] In this embodiment, based on the third counting time corresponding to the third timer and the total amount of read data, the amount of data read by the virtual disk within a unit time, ie, the read rate of the virtual disk, is calculated.
[0088] S1034: Calculate a read performance index of the virtual disk based on the fourth counting time and the number of reads.
[0089] In this embodiment, the number of read operations completed by the virtual disk within a unit time, ie, the read IOPS of the virtual disk, is calculated based on the counting time of the fourth counting time corresponding to the fourth timer and the number of read operations.
[0090] In this embodiment, in response to the read operation of the virtual machine, the first monitoring program counts the read data read from the cache through the third counter to obtain the total number of read data and the third counting time, and can monitor the data reading activity of the virtual disk in real time; counts the number of times data is read from the cache through the fourth counter to obtain the number of reads and the fourth counting time; calculates the read rate of the virtual disk based on the third counting time and the total number of read data; calculates the read performance index of the virtual disk based on the counting time and the number of reads of the fourth counting time, realizes the monitoring of the virtual disk read performance, and improves the accuracy of virtual disk monitoring.
[0091] Combination Figure 3 As shown, before executing S1031 - S1034 , referring to the previous embodiment, S101 - S102 are executed to obtain the disk capacity data and write performance data of the virtual disk.
[0092] See also Figure 4 , which is a flow chart of another embodiment of a virtual disk performance monitoring method provided by the present application. Figure 4 As shown, in a virtualized environment, multiple virtual machines may share the same physical storage device. If the read and write rate of the virtual disk corresponding to the current virtual machine is too high, it may occupy a large amount of resources, resulting in other virtual machines being unable to obtain sufficient resources, thereby affecting the performance and stability of the physical storage device. Therefore, it is necessary to control the read and write rate of the virtual disk based on the performance of the monitored virtual disk. Based on the above embodiment, the virtual machine also includes a virtualized backend system, and the method may also include:
[0093] S104: The preset write rate threshold and read rate threshold are transmitted to the monitoring program by using an inter-process communication method through the management program in the virtualized backend system.
[0094] In this embodiment, the management program running in the virtualized backend system adopts an inter-process communication method such as TCP or a local socket method to transmit the preset write rate threshold and read rate threshold to the monitoring program running in the virtualized frontend.
[0095] S105: The monitoring program compares the write rate with the write rate threshold, and compares the read rate with the read rate threshold.
[0096] In this embodiment, the monitoring program is run to compare the calculated write rate with the obtained write rate threshold, and to compare the calculated read rate with the obtained read rate threshold.
[0097] S106: When it is determined that the write rate is greater than the write rate threshold or the read rate is greater than the read rate threshold, control the write rate and the read rate.
[0098] In this embodiment, when it is determined that the write rate is greater than the write rate threshold or the read rate is greater than the read rate threshold, the write rate and the read rate are controlled. Specifically, controlling the write rate and the read rate may include controlling the virtual front-end system to reduce the speed of building a blank cache, thereby reducing the speed of writing data into the cache.
[0099] In this embodiment, based on the preset write rate threshold and read rate threshold, the threshold is transmitted to the monitoring program through the management program in the virtualized backend system by using the inter-process communication method. The monitoring program compares the first counter value with the write rate threshold, and compares the third counter value with the read rate threshold to ensure that the performance of the virtual disk will not be degraded due to excessively high rate when processing data; when it is determined that the first counter value is greater than the write rate threshold or the third counter value is greater than the read rate threshold, the write rate and the read rate are controlled, thereby improving the operating performance of the virtual disk and avoiding overload of physical storage device resources.
[0100] Furthermore, based on the above embodiment, the method may further include:
[0101] The preset write performance indicator threshold and read performance indicator threshold are transmitted to the monitoring program through the management program by using the inter-process communication method.
[0102] In this embodiment, the management program running in the virtualized backend system adopts an inter-process communication method such as TCP or a local socket method to transmit the preset write IOPS threshold and read IOPS threshold to the monitoring program running in the virtualized frontend.
[0103] The monitoring program compares the write performance indicator to the write performance indicator threshold and compares the read performance indicator to the read performance indicator threshold.
[0104] In this embodiment, the monitoring program is run to compare the calculated write IOPS with the obtained write IOPS threshold, and to compare the calculated read IOPS with the obtained read IOPS threshold.
[0105] When it is determined that the write performance index is greater than the write performance index threshold or the read performance index is greater than the read performance index threshold, the number of writes and the number of reads are controlled.
[0106] In this embodiment, when it is determined that the write IOPS is greater than the write IOPS threshold or the read IOPS is greater than the read IOPS threshold, the number of writes and the number of reads are controlled. Specifically, controlling the number of writes and the number of reads may include controlling the virtual front-end system to reduce the number of blank caches constructed to temporarily store data and reduce the number of times data is read from the cache, and controlling the number of times the virtualized back-end system writes the data to be read into the cache.
[0107] In this embodiment, based on the preset write performance index threshold and read performance index threshold, the threshold is transmitted to the monitoring program through the management program in the virtualized backend system by using the inter-process communication method. The monitoring program compares the second counter value with the write performance index threshold, and compares the fourth counter value with the read performance index threshold to ensure that the virtual disk does not cause performance degradation due to the high number of times when processing data; when it is determined that the second counter value is greater than the write performance index threshold or the fourth counter value is greater than the read performance index threshold, the number of writes and the number of reads are controlled, thereby improving the operating performance of the virtual disk and avoiding overload of physical storage device resources.
[0108] Further, based on the above embodiment, the virtual machine may further include a virtualized application system, and the method may further include:
[0109] Through the management program, the write performance data and read performance data of the virtual disk are displayed in the virtualization application system.
[0110] In this embodiment, the obtained virtual disk performance data can be sent to a virtualization application system, such as a cloud computing management platform, a virtualization monitoring platform, etc., for display through the management program, so that users can view and manage the virtual disk performance data in the interface of the virtualization application system.
[0111] In this embodiment, the write performance data and the read performance data of the virtual disk are displayed in the virtualization application system through the management program, so that the user can timely discover potential problems of the virtual disk and improve the performance of the virtual disk.
[0112] Further, based on the above embodiment, before S101 “running the virtual disk monitoring program to obtain disk capacity data of the virtual disk in the virtual machine”, the method may further include:
[0113] Physical resources are scheduled through the virtualization kernel program to build the basic resources of the virtual target.
[0114] In this embodiment, for example, according to the required physical resources, including CPU, memory, storage device and network device, etc., a virtualization kernel program is installed on the host machine, and the physical resources are abstracted into virtual resources, such as virtual CPU, virtual memory, virtual storage and virtual network, etc., through virtualization technology. Then, according to the resource requirements of the virtual target, the virtualization kernel program is used to schedule and allocate resources, so as to utilize the allocated virtual resources to build the basic resources required by the virtual target.
[0115] The IO device is simulated by the virtualized user-mode program, and the virtual target is run; the virtual target includes the virtual disk.
[0116] In this embodiment, for example, the virtualized user state program can use QEMU, KVM, etc. to simulate IO devices. Through the virtualized user state program, the IO devices required by the virtual target, such as virtual network cards, virtual disks, etc., are simulated. Taking the virtual disk as an example, the capacity, read and write speed and other parameters of the virtual disk are configured to ensure that its performance meets the requirements of the virtual target. When the deployment and configuration of the virtual target are completed in the virtual environment, the virtual target is run.
[0117] In this embodiment, physical resources are scheduled by the virtualized kernel program to build the basic resources of the virtual target, and then the IO device is simulated by the virtualized user-mode program and the virtual target is run. This can build a test environment similar to the real environment, which helps to perform various complex tests and simulations in the virtual target and improve the security of the real system.
