The invention relates to a host operation and maintenance analysis method. The server comprises a data acquisition module, a real-time stream processing module, a data storage, retrieval and analysismodule and a WEB service module. The data acquisition module comprises a Flume data acquisition and transmission module and a Kafka data acquisition and distribution module. The method comprises: theFlume data acquisition and transmission module acquiring SMF data of a host, and aggregating log data and then transmitting the data to the HDFS distributed file system; the Kafka data acquisition anddistribution module transmitting received data to the HBase database after real-time streaming processing, and the data storage, retrieval and analysis module analyzing and sorting the received hostoperation and maintenance data and then creating a data search engine for the WEB service module to call and use. According to the method, a Flume and Kafka combined data acquisition and distributionmode is adopted, and the method has the characteristics of high data integration and operation and maintenance efficiency.
