not_analyzedElasticsearch automatically uses its own default word breakers (spaces, dots, slashes, and so on) to analyze fields. A word breaker is very important for searching and scoring, but it greatly reduces the performance of index write and aggregate requests. So the Logstash template defines a field called a "multi-field" (Multi-field) type, and sets the field to not enable the word breaker. That is, when you want to get the aggregated result of the URL field, do not use "url" directly,

/class1?pretty 'The data that is searched in Es can be understood broadly as two categories:Types:exactFull-textExact value: Refers to the raw original value, and the exact match when searching;Full-text: Used to refer to the data in the text, to determine how many programs the document matches the query request, that is, to evaluate the relevance of the document to the user request query;In order to complete the Full-text search, es must first parse the text and create an inverted index; the da

I've recently learned a little about elk:ELK consists of three open source tools, Elasticsearch, Logstash and KiabanaOfficial website: https://www.elastic.co/products| Elasticsearch is an open source distributed search engine, it features: distributed, 0 configuration, automatic discovery, Index auto-shard, index copy mechanism, RESTful style interface, multi-data source, automatic search load, etc.L Logstash is a fully open source tool that collects, analyzes, and stores your logs for later use

Introduction:First of all, we should all know the function and principle of WAF, the market is basically using Nginx+lua to do, here is no exception. But slightly different, the logic is not in Lua.Instead of using Elasticsearch for analysis, LUA only uses the analyzed IP address to block, greatly reducing the direct interruption caused by false positives and other failures.The architecture diagram is as follows:You can get the following useful data:1.pv,uv,ip and other data2. After the analysis
