摘要： A network log time alignment method and an apparatus are provided. The method includes: obtaining log data stored in multiple network devices; parsing the log data to obtain features of each network device; determining associated features of the multiple network devices according to the features of each network device, where the associated features are features that are of the network devices and that have an association in space; and then, performing alignment on log time in multiple pieces of log data according to the associated features. Therefore, associated features of related devices of a network fault can be found, and log time are automatically aligned according to the associated features, thereby improving the efficiency and the accuracy of the fault location and sectionalization.

摘要： A network detection method and apparatus are provided. The method includes: obtaining parsed data of one or more target network performance indicators, where the parsed data of each target network performance indicator includes measured values corresponding to the target network performance indicator at a plurality of collection time points; analyzing the parsed data, to obtain a plurality of data sequences, where each data sequence includes a plurality of measured values corresponding to a target network performance indicator; determining an abnormal collection time point or an abnormal data sequence based on the plurality of data sequences; and determining that a network performance indicator corresponding to the abnormal collection time point or the abnormal data sequence is an abnormal network performance indicator.
