2.瓶颈识别：（1）预设回归模型：基于CPU使用率、内存占用、磁盘I/O速率、网络带宽占用4种资源占用情形，预设多元线性回归模型（预设为：节点管理操作时系统响应时间周期=a×CPU使用率+b×内存占用+c×磁盘I/O速率+d×网络带宽占用；其中a,b,c,d为回归系数）；（2）模型拟合：基于数据集X，使用最小二乘法（OLS）拟合模型，计算回归系数a,b,c,d；（3）根据回归系数的绝对值大小，确定对节点管理操作时系统响应时间周期影响最大的资源，即为影响最大的性能瓶颈。

This dataset provides multi-faceted value for blockchain network node management systems and their stakeholders. It not only helps system developers optimize resource allocation and improve node management efficiency, but also offers critical technical references and improvement directions for other technology developers, cloud computing service providers, hardware suppliers and other parties, contributing to the optimization of blockchain network performance, technological innovation and industrial upgrading. For the company (as the system developer), based on identified performance bottlenecks (such as excessive network bandwidth occupation), it can optimize resource allocation, e.g., increasing network bandwidth, optimizing node communication protocols, improving data compression algorithms, etc., to enhance node management efficiency. This dataset also provides valuable references for other technology developers when optimizing the design of similar blockchain network node management systems; offers a basis for cloud computing service providers to optimize cloud service resource allocation strategies; and provides improvement directions for hardware suppliers such as network equipment and storage equipment developers to produce higher-performance hardware that meets the requirements of blockchain network node management.

1. Data Collection and Preprocessing
(1) Data Collection: Collect data fields reflecting the real-time performance of the system from the logs of the company's blockchain network node management system, including the occurrence time of node management events (accurate to the second), the system response time cycle/second during node management operations, and resource occupation status (specifically CPU usage/%, memory occupancy/MB, disk I/O rate/MBps, network bandwidth occupation/Mbps).
(2) Data Preprocessing: Clean the data to remove outliers; aggregate the data using a dynamic 1-hour window (i.e., 1 hour forward from the current time point) to form the structured dataset X.

2. Bottleneck Identification
(1) Preset Regression Model: Based on the four resource occupation scenarios of CPU usage, memory occupancy, disk I/O rate and network bandwidth occupation, preset a multiple linear regression model (preset as: system response time cycle during node management operations = a × CPU usage + b × memory occupancy + c × disk I/O rate + d × network bandwidth occupation; where a, b, c, d are regression coefficients).
(2) Model Fitting: Use the ordinary least squares (OLS) method to fit the model based on dataset X, and calculate the regression coefficients a, b, c, d.
(3) Determine the resource that has the greatest impact on the system response time cycle during node management operations based on the absolute values of the regression coefficients, which is the most significant performance bottleneck.
