[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, 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 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 making creative work are within the scope of protection of this application.

[0053] The first embodiment of the present application provides a blockchain performance testing method, which can be applied to Figure 1 The system architecture shown includes at least a blockchain testing platform 101 and a server to be tested 102, and the blockchain testing platform 101 and the server to be tested 102 establish a communication connection.

[0054] The method can be applied to the blockchain testing platform 101 in the system architecture to perform blockchain performance testing on the server 102 to be tested. The specific composition of the blockchain testing platform 101 is not limited.

[0055] Specifically, this method can be applied to Figure 2 The network topology, Figure 2 A network topology diagram of a blockchain performance testing method provided for one embodiment of the present application.

[0056] Among them, the stress server is used to generate load and perform stress testing. Grafana, as a visualization tool, provides test result visualization services for blockchain performance testing. Prometheus is used to collect data during the performance testing process.

[0057] Next, based on the system architecture or network topology, the blockchain performance testing method is described in detail. A blockchain performance testing method, such as Figure 3 ,include:

[0058] Step 301: Acquire test items of the file system of the server to be tested.

[0059] Each test item may include six variables, namely, block size (block_list), read-write ratio (rw_list), random ratio (random_list), test time (time), process (threads) and read-write mode (way). The specific values ​​of the variables may be set or selected as needed. Of course, they may also be automatically allocated according to the server to be tested. The value of each variable may be one or more. Multiple test items may be generated through free combination. Specifically, the test items to be tested may be exhaustively listed through a for loop, thereby realizing the definition of the test items.

[0060] For each test item, the performance indicators of the test can be divided into two parts, one is the number of read and write operations per unit time (Input / Output Operations Per Second, i.e. iops), and the other is the data throughput, that is, the amount of data that can be transmitted per unit time.

[0061] Since the storage medium of blockchain has a minimum read and write unit, mechanical disks are usually 512 bytes, and solid-state drives are usually 4kb, 4k block size can be used for testing when testing IOPS. However, due to factors such as network bandwidth and system IO strategy, 1M block size can be used for testing when testing data throughput performance.

[0062] In terms of performance testing, in order to avoid false performance caused by storage medium cache, direct reading is usually selected for storage medium performance testing, and IOPS and throughput are included. The block size is 4K and 1M, and the test time is 5 to 30 minutes. For the mean time to repair (MTTR) in the reliability direction of the storage medium, it is necessary to use greater pressure to initiate random IO to the storage medium, and meet daily usage scenarios, the block size is more than 1M, the read-write method is 70% read, and the time is more than 168 hours.

[0063] Based on the above conclusions, the following commonly used test indicators are given:

[0064] Performance indicators: 4k random write, 4k random read, 4k sequential read, 4k sequential write, 1M random write, 1M random read, 1M sequential read, 1M sequential write, time is 5 minutes for each item, and 32 concurrent processes.

[0065] Reliability indicators: 1M mixed random read and write, read-write ratio of 7:3, time of 168 hours, concurrent processes of 64.

[0066] During testing, the values ​​of each variable in each test item can be determined based on the above commonly used test indicators to meet the test needs, without specific restrictions.

[0067] Step 302: Determine the input and output load items of each host in the server to be tested according to the test items and the host address array of the server to be tested.

[0068] The server to be tested generally includes multiple hosts. The host address array is used to store the host addresses of each host. The host address array of the server to be tested, as well as the user name and password of each host, can be obtained first. According to the host address array, user name and password, fast mutual trust between the hosts is established. Specifically, a shell script can be used to achieve fast mutual trust between hosts by using ssh-copy-id and expect tools.

[0069] After achieving rapid mutual trust between hosts, data communication between hosts is facilitated. By defining block size, read-write ratio, random ratio, test time, process, and read-write method, combined with the host address array, the input and output load items (also called IO load items) of each host can be determined through an exhaustive for loop.

[0070] Step 303: Test the input and output load items of each host through the input and output load tool to obtain first test data, which is used to characterize the blockchain performance upper limit of the server to be tested.

[0071] When the IO load items of multiple hosts are tested for performance using the input and output load tool (IO load tool), all processes can be carried out in series, and the test start time T1 and end time T2 are recorded. The data obtained between T1 and T2 is the upper limit of blockchain performance.

[0072] This method can automatically obtain the input and output load items of each host by obtaining the test items of the file system of the server to be tested and combining them with the host address array of the server to be tested. By testing the input and output load items of each host, the blockchain performance upper limit of the server to be tested can be obtained. Blockchain performance testing can be implemented without mastering complex code capabilities, reducing the difficulty of testing.

[0073] In one embodiment, after the input and output load items of each host are performance tested by an input and output load tool and first test data is obtained, the method further includes: blockchaining the file system by a blockchain management tool to obtain N blocks; and testing each block by a blockchain performance testing tool to obtain second test data, wherein the second test data is used to characterize the blockchain performance of the block.

[0074] When testing the block performance on the file system through the blockchain performance testing tool, all processes can be carried out serially, and the test start time is recorded as T3 and the end time is T4. The data between T3 and T4 is the blockchain performance data.

[0075] In this embodiment, the blockchain performance testing tool can be the hyperbench software tool in Table 1. When testing the block, the four variables of the number of virtual machines, test time, host address, and rate can be considered, and a for loop can be used for exhaustive enumeration to define the test items for all block tests, thereby realizing automatic IO generation of the blockchain, reducing the operating difficulty of the tester, and improving the test efficiency.

[0076] In one embodiment, before obtaining the test items of the file system of the server to be tested, the method further includes setting up a test environment.

[0077] Building a test environment includes building the hardware environment, network environment, and software environment.

[0078] Building a hardware environment includes: configuring the first disk array and the second disk for the server to be tested; the performance of the first disk array is used to characterize the performance of the server to be tested. In order to ensure the security of blockchain data, the disk array technology is used to perform hard raid processing on the hard disk, and the XOR check method is used to ensure that if only one disk is damaged, data will not be lost, thereby improving the security of data and blockchain.

[0079] In addition, the first disk array for testing performance and the second disk for deploying the system are two sets of disks respectively to eliminate interference caused by system factors. Of course, the second disk can also be a disk array without limitation.

[0080] To build a network environment, you can build Figure 2 The network topology shown will not be described in detail.

[0081] Building a software environment includes: installing the basic system of the server to be tested on the second disk; initializing the first disk array to obtain the file system of the server to be tested, and mounting the file system to the basic system; deploying software tools; and using the software tools for performance testing or collecting data during performance testing.

[0082] Specifically, you can use the Linux system as the basic system. Of course, you can also use the Mac and Windows systems in the Mac and Windows environments.

[0083] After the system is installed, format the disk array and use the tool to initialize the disk array to make it a usable file system. Then mount the file system to the system environment. After the above steps are completed, deploy the following software, as shown in Table 1.

[0084] Table 1

[0085]

[0086]

[0087] After deploying the software tool, before obtaining the test items of the file system of the server to be tested, all tools can also be tested to see if the required information can be correctly obtained. The specific steps include: performing a status test on the software tool to obtain a status test result; if the status test result is consistent with the pre-stored target result of the software tool, it is determined that the software tool status is normal.

[0088] In this embodiment, the target result of the software tool can be pre-stored. If the status test result is consistent with the target result, it means that the software tool can be used normally and the status is normal. The names and abbreviations of the information obtained by the software tool are shown in Table 2.

[0089] Table 2

[0090]

[0091] In one embodiment, during the process of testing each block, the method further includes:

[0092] Obtain the indicator data collected during the test; write the indicator data into a log file, and upload the indicator data to the blockchain to save all indicator data during the test in the block; the log file is used to record the information of the collected indicator data;

[0093] Call the contract analysis record file in the server to be tested and the indicator data on the blockchain to generate a collectible file; the collectible file includes the feature information and test item information of this test;

[0094] Push the collectible files to the database of the server under test.

[0095] In this embodiment, when collecting data, a scheduled task can be used and written as a service to obtain the indicators mentioned in Table 2. All generated logs can be written into a log file using a fixed format, such as written in the format of time, level, and content as the three sections of the log file. Log files stored in the same format are easy to read and use. Of course, the above specific formats are only examples and do not represent restrictions on the log file format.

[0096] The Prometheus database can be used for the collected data. The Prometheus database has a situation where availability is greater than consistency and tolerates the loss of some replica data, which will result in inaccurate data. In addition, Prometheus is not friendly to log events. Therefore, the database collection method is modified in this embodiment, such as Figure 4 As shown, the improved acquisition process is as follows, including:

[0097] Step 401, after the script completes data collection, the data is written to the log record file and uploaded directly to the chain.

[0098] Step 402: Each block stores all data of a single test item.

[0099] Step 403, after calling the contract analysis record file and on-chain data through a third-party script, a collectible file is generated. The generated data needs to contain the feature information (version) of this test and the test item information (option).

[0100] Step 404: Push the data to the database through pushgateway, where the collection interval from step 401 to step 404 should be the interval required by the test particle. The Prometheus database generally uses pull to pull data. In this embodiment, the pushgateway component is used to push the data to the Prometheus database to ensure the integrity of the data.

[0101] Step 405, after the content of the log file is disassembled into three sections, it is put into the collection file in the form of key-value pairs. After all tests are completed, it is pushed to the database, and the version field of each test is added for subsequent search.

[0102] The improved Prometheus database collection method can ensure the accuracy and completeness of the collected data, and improve the accuracy of subsequent data display, performance analysis, and performance bottleneck analysis.

[0103] In one embodiment, a visualization tool may be used to display data, including: using a visualization tool to display at least one of indicator data, log files, and test results, wherein the test results include at least one of first test data and second test data.

[0104] In this embodiment, the visualization tool can use Grafana. When displaying, the indicator data can be presented using a line chart, the log file information can be presented using a table, and the test results can be quickly switched using Variables to improve the visualization display effect of the test results.

[0105] This embodiment can not only display the data, but also display and analyze the test performance.

[0106] You can filter the data of each corresponding test item according to the option, which makes it convenient to view the corresponding data under the option and analyze it. The data can be differentiated according to time. For example, the data obtained from T1 to T2 is the upper limit of the blockchain performance in this scenario, and the data obtained from T3 to T4 is the blockchain performance data, which improves the efficiency of data analysis.

[0107] In one embodiment, after obtaining the test data, performance bottleneck analysis may be performed.

[0108] When analyzing bottlenecks, you can analyze based on environmental factors. The calculation process of environmental factors can be as follows:

[0109] Environmental factor = (66 + Temp-Idle-SER-RER) * Util / 10000

[0110] Among them, Temp is the hard disk temperature of the server to be tested, SER is the seek error rate, RER is the error read rate, Idle is the percentage of idle CPU, and Util is the percentage of CPU time during the issuance of input and output requests. The environmental factor can be calculated based on the above parameters, and the blockchain performance bottleneck analysis of the server to be tested can be performed based on the environmental factor.

[0111] The blockchain performance testing method provided in this embodiment includes the following steps: setting up a test environment, conducting performance testing according to IO indicators and an automated IO generation solution, real-time collection of valid data during the test, real-time customized chart generation and display, and performance status and bottleneck analysis.

[0112] This embodiment can customize the IO automatic generation solution, support any mainstream platforms such as mac, linux, windows, etc., display data in charts, customizable styles, beautiful interface, data persistence, easy to filter, view history, comprehensive available data, easy to search logs, and analyze performance and bottlenecks.

[0113] This solution is very friendly to operation and maintenance personnel. They do not need to master complex front-end code capabilities to realize test result visualization, and can almost achieve a once-and-for-all effect after a process is completed. They can also obtain storage medium performance fluctuations and performance indicators through images, quickly obtain blockchain performance ceilings and locate blockchain performance bottlenecks, and ensure the accuracy and effectiveness of test data through data chain verification, without spending a lot of time extracting valid information from a lot of test data.

[0114] Based on the same technical concept, the second embodiment of the present application provides a blockchain performance testing device, such as Figure 5 ,include:
