注：Logstash意思是日志存储，下文中对本词使用英文。

Logstash 介绍

Logstash is an open source data collection engine with real-time pipelining capabilities（功能）. Logstash can dynamically unify（统一） data from disparate（不同的） sources and normalize the data into destinations（目的地） of your choice. Cleanse（净化） and democratize（大众化） all your data for diverse（不同的） advanced downstream（下游） analytics and visualization（形象化） use cases.

Logstash 是开源的具有实时输入数据能力的数据收集引擎。Logstash可以把来自不同的源的数据动态的写入你选择的目的地并对输入的数据进行规范化。根据需求进行分析和展示。

While Logstash originally（最初） drove innovation（创新） in log collection, its capabilities extend well beyond（超越） that use case. Any type of event can be enriched and transformed（转变） with a broad（宽的） array of input, filter, and output plugins, with many native codecs further（更好地） simplifying（简化） the ingestion（吸收） process. Logstash accelerates（加速） your insights（洞察力） by harnessing（利用） a greater volume and variety（多样） of data.

Logstash升级版本的时候，老版本对新版本的兼容新很好。事件的类型是一组input、filter、和output插件，所以可以很方便扩展，可以使用本地编码更好简化吸收日志的过程。

Logstash Loves Data

Collect more, so you can know more. Logstash welcomes data of all shapes and sizes.

搜集更多,这样你就可以知道更多。Logstash可以存储各种各样的数据。

Logs and Metrics
Where it all started.

• Handle all types of logging data
  • Easily ingest（摄取） a multitude（大批的） of web logs like , and application logs like for Java
  • Capture many other log formats like , , networking and firewall logs, and more
• Enjoy complementary（补充的） secure log forwarding capabilities with
• Collect metrics from , , , , and many other infrastructure（基础设施） and application platforms over and

日志和度量
这是一切开始的地方。

• 处理很多类型的日志
• 那些可以容易获取的<code>Apache</code>之类的web日志，应用日志如java的log4J
• 其他的格式化的日志如<i>syslog,Windows event logs,网络和防火墙日志等等</i>
• Filebeat转发来的安全日志。
• , , , , 和一些其他的（基础设施） and 基于 and 的应用平台

The Web
Unlock the World Wide Web.

• Transform into events ()
• Consume（消耗） from web service firehoses（消防带） like for social sentiment（情感） analysis
• Webhook（网络连接） support for GitHub, HipChat, JIRA, and countless（无数的） other applications
• Enables many alerting use cases
• Create events by polling（投票） on demand ()
• Universally（普遍） capture health, performance, metrics, and other types of data from web application interfaces
• Perfect for scenarios where the control of polling is preferred over receiving

• Http事件

Data Stores and Streams
Discover more value from the data you already own.

• Better understand your data from any relational database or NoSQL store with a interface ()
• Unify（统一） diverse（不同的） data streams from messaging queues like Apache (), , , and

数据存储和数据流

Sensors and IoT
Explore an expansive breadth of other data.

• In this age of technological advancement, the massive IoT world unleashes endless use cases through capturing and harnessing data from connected sensors.
• Logstash is the common event collection backbone for ingestion of data shipped from mobile devices to intelligent homes, connected vehicles, healthcare sensors, and many other industry specific applications.
• as Logstash, in conjunction with the broader ELK stack, centralizes and enriches sensor data to gain deeper knowledge regarding a residential home.

Easily Enrich Everything

The better the data, the better the knowledge. Clean and transform your data during ingestion to gain near real-time insights immediately at index or output time. Logstash comes out-of-box with many aggregations and mutations along with pattern matching, geo mapping, and dynamic lookup capabilities.

• is the bread and butter of Logstash filters and is used ubiquitously to derive structure out of unstructured data. Enjoy a wealth of integrated patterns aimed to help quickly resolve web, systems, networking, and other types of event formats.
• Expand your horizons by deciphering from IP addresses, normalizing complexity, simplifying and data, sensitive information, and further enriching your data with or Elasticsearch .
• Codecs are often used to ease the processing of common event structures like and events.
