CompositionElk consists of three parts: Elasticsearch, Logstash and Kibana.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.Logstash is a fully open source tool that collects, analyzes, and stores your logs for later useKibana is an open source and
SummaryWhen we use Logsatsh to write the configuration file, if we read too many files, the matching is too much, will make the configuration file hundreds of thousands of lines of code, may cause reading and modification difficulties. At this time, we can put the configuration file input, filter, output in a different configuration file, or even the input, filter, output again separated, put in a different file.At this time, the later need to delete and change the contents of the search, it is
