Aiming at the problem that the large scale of data in log information is not conducive to abnormal reading detection, a large-scale network abnormal reading detection method based on log information is proposed. Abstract algorithms were introduced to merge log information in different formats and extract unified network events, so as to obtain integrated log information, remove redundant data and reduce the computational burden;The dimensions of log information were reduced to obtain low-dimensional data for subsequent detection;Combined with the temporal correlation of network readings and the spatial correlation of adjacent network readings, phased detection was implemented to complete the detection of large-scale network abnormal readings. The experimental results show that the proposed method can effectively improve the detection rate and detection accuracy, reduce the false alarm rate, and save the detection time, which indicates that the method has a good detection effect.
