提高安全性
集中存放日志
缺陷:对日志的分析困难
Elasticsearch:存储,索引池
Logstash:日志收集器
Kibana:数据可视化
1,将日志进行集中化管理
2,将日志格式化(Logstash)并输出到Elasticsearch
3,对格式化后的数据进行索引和存储(Elasticsearch)
4,前端数据的展示(Kibana)
提供了一个分布式多用户能力的全文搜索引擎
接近实时
集群
节点
索引:索引(库)-->类型(表)-->文档(记录)
分片和副本
一款强大的数据处理工具,可以实现数据传输、格式处理、格式化输出
数据输入、数据加工(如过滤,改写等)以及数据输出
Shipper
Indexer
Broker
Search and Storage
Web Interface
一个针对Elasticsearch的开源分析及可视化平台
搜索、查看存储在Elasticsearch索引中的数据
通过各种图表进行高级数据分析及展示
Elasticsearch无缝之集成
整合数据,复杂数据分析
让更多团队成员受益
接口灵活,分享更容易
配置简单,可视化多数据源
简单数据导出
