Elasticsearch,Kibana,Logstash,NLog实现ASP.NET Core 分布式日志系统 Elasticsearch 官方网站 Elasticsearch 文档 NLog.Targets.ElasticSearch package Elasticsearch - 简介 Elasticsearch 作为核心的部分,是一个具有强大索引功能的文档存储库,并且可以通过 REST API 来搜索数据。 它使用 Java 编写,基于 Apache Lucene ,尽管这些细节隐藏在 API 中。 通过被索引的字段,可以用许多不同的聚合方式找到任何被存储(索引)的文档。 但是,ElasticSearch不仅仅只提供对这些被索引文档的强大搜索功能。 快速、分布式、水平扩展,支持实时文档存储和分析,支持数百台服务器和 PB 级索引数据。 同时作为 Elastic stack (aka ELK) 的核心,提供了诸如 LogStash、Kibana 和更多的强大应用。 Kibana 是 Elasticsearch 中专门提供强有力的可视化查询Web应用程序。 使用Kibana,能非常简单地为 Elasticsearch 中索引的数据创建查询、图表和仪表盘。 Elasticsearch开放了一个 REST API,你会发现许多文档示例是 HTTP 调用,你可以尝试使用 curl 或

Filebeat在windows下安装使用

白昼怎懂夜的黑 提交于 2020-04-08 11:54:21
一、windows下安装Filebeat 官网下载安装包 解压到指定目录,打开解压后的目录,打开filebeat.yml进行配置。 1、配置为输出到ElasticSearch ①:配置 Filebeat prospectors->path 这里的路径是所要收集日志的路径 。。eg:在当前目录下建一个data文件夹,里面放下载的示例文件( 在Logstash那篇 ),人家应该是linux下的文件。 我这里将下载的日志文件 加了后缀.log ,放在data目录下 所以我的配置如下: - type: log # Change to true to enable this input configuration. enabled: true # Paths that should be crawled and fetched. Glob based paths. paths: - E:\filebeat-6.6.2-windows-x86_64\data\logstash-tutorial.log\*.log #- c:\programdata\elasticsearch\logs\* ②:配置 enabled: true 这个配置很重要,只有配置为true之后配置才可生效,否则不起作用。 ③:配置Outputs ,这里的Outputs有elasticsearch,logstash

Regexp in Grok sometimes catches a value sometimes not

一笑奈何 提交于 2020-03-27 05:44:17
问题 I've a code in grok, which captures messages, and if they meet a given criteria, they get a tag. My problem is, that sometimes this filter works while testing, and sometimes does not. The regexp in question is the following: ^(?!(?:\d\d\d\d-\d\d-\d\d.\d\d:\d\d:\d\d)).*$ This line checks if the given message does not begin with a given time stamp format. In other words: if the given message does not begin with this time stamp, then it gets a tag. You can test it yourself with this online

logstash与flume区别

-1. Logstash是一个开源的服务器端数据处理管道,可以同时从多个数据源获取数据,并对其进行转换,然后将其发送到你最喜欢的“存储”。 Inputs:用于从数据源获取数据,常见的插件如file, syslog, redis, beats 等 Filters:用于处理数据如格式转换,数据派生等,常见的插件如grok, mutate, drop, clone, geoip等 Outputs:用于数据输出,常见的插件如elastcisearch,file, graphite, statsd等 Logstash最值得一提的是,在Filter plugin部分具有比较完备的功能,比如grok,能通过正则解析和结构化任何文本,Grok 目前是Logstash最好的方式对非结构化日志数据解析成结构化和可查询化。此外,Logstash还可以重命名、删除、替换和修改事件字段,当然也包括完全丢弃事件,如debug事件。还有很多的复杂功能供程序员自己选择,你会发现这些功能Flume是绝对没有(以它的轻量级线程也是不可能做到的)。当然,在input和output两个插件部分也具有非常多类似的可选择性功能,这一点跟Flume是比较相似的。 -2. Flume 是一个分布式、可靠和高可用的服务,用于收集、聚合以及移动大量日志数据,使用一个简单灵活的架构,就流数据模型。这是一个可靠、容错的服务。

Using field as input to Logstash Grok filter pattern

别来无恙 提交于 2020-01-25 04:27:04
问题 I'm wondering if it is possible to use a field in the Logstash message as the input the to Grok pattern. Say I have an entry that looks like: { "message":"10.1.1.1", "grok_filter":"%{IP:client}" } I want to be able to do something like this: filter { grok { match => ["message", ["%{grok_filter}"]] } } The problem is this crashes Logstash as it appears to treat "%{grok_filter}" as the Grok filter itself instead of the value of grok_filter. I get the following after Logstash has crashed: The
