The invention discloses a log-based big data analysis method, the log-based big data analysis method mainly includes the steps of collecting data in each server according to a configuration file of arelated Beats application; and collecting the data collected by the Beats application by LogStash and storing the data in ElasticSearch in an order generated by automatic indexing. The ElasticSearch provides a concise Restful-style query interface to the outside world and develops Lucene through the Java program and uses the Lucene as its core to realize query data calling, i.e. all indexing and searching functions are realized, the functions of accurately locating and searching log information and analyzing related data are achieved, and accurate business data is acquired. Finally, Echart isused for visual display to hide the complexity of the Lucene, which makes indexing and searching easy and intuitive.
