ELK日志分析简介 1.1 ELK日志分析概述   ELK可运行于分布式系统之上,通过搜集、过滤、传输、储存,对海量系统和组件日志进行集中管理和准实时搜索、分析,使用搜索、监控、事件消息和报表等简单易用的功能,帮助运维人员进行线上业务的准实时监控、业务异常时及时定位原因、排除故障、程序研发时跟踪分析Bug、业务趋势分析、深度挖掘日志的大数据价值。ELK主要可解决的问题如下:1.日志查询,问题排查,上线检查.2.服务器监控,应用监控,错误报警,Bug管理. 3.性能分析,安全漏洞分析。综上,ELK是一套方便、易用的日志分析开源解决方案。 1.2 ELK主要组件介绍   生产环境中,ELK通常由以下4个组件构成: 1.2.1 ElasticSearch组件   ElasticSearch是一个基于Lucene的开源分布式搜索服务器。它的特点有:分布式,零配置,自动发现,索引自动分片,索引副本机制,restful风格接口,多数据源,自动搜索负载等。它提供了一个分布式多用户能力的全文搜索引擎,基于RESTful web接口。Elasticsearch是用Java开发的

ELK 是由三部分组成的一套日志分析系统, Elasticsearch: 基于json分析搜索引擎,Elasticsearch是个开源分布式搜索引擎,它的特点有:分布式,零配置,自动发现,索引自动分片, 索引副本机制,restful风格接口,多数据源,自动搜索负载等。 Logstash: 动态数据收集管道,Logstash是一个完全开源的工具,它可以对你的日志进行收集、分析,并将其存储供以后使用 Kibana: 可视化视图,将elasticsearh所收集的data通过视图展现。kibana 是一个开源和免费的工具,它可以为 Logstash 和 ElasticSearch 提供的日志分析友好的 Web 界面,可以帮助您汇总、分析和搜索重要数据日志。 一、使用docker集成镜像 安装docker elk集成镜像包 名字是 sebp/elk 1.安装 docke、启动 yum install docke service docker start 2.下载 sebp/elk docker pull sebp/elk 无法下载、报错 : unauthorized: authentication required 这是国外网络的问题 解决1 用网易镜像 vim /etc/docker/daemon.json 这个json文件不存在的,不需要担心,直接编辑 把下面的贴进去,保存,重启即可

问题 I'm writing a kibana plugin and a logstash pipeline. For my tests, I just wrote a logstash input like that: input { beats { port => 9600 ssl => false ssl_verify_mode => "none" } } But when I try to open a connection with node (code above): invoke = (parameters, id, port, host) => { var fs = require('fs'); console.log(`Sending message in beats, host= ${host}, port= ${port}, message= ${parameters.message}`); var connectionOptions = { host: host, port: port }; var client = lumberjack.client

Cannot retrieve data which includes specific symbols in Kibana

我怕爱的太早我们不能终老 提交于 2021-02-11 07:05:04
问题 I try to use Kibana to retrive the comment data which includes some specific symbols like ? and 。 They are not general symbols. I try to use escape character \ for them, the KQL is like comment:\? or comment:\\? , but it doesn't work, can anyone help? 回答1: When you create a sample doc and let ES auto-generate the mapping for you, POST comments/_doc { "comment": "?" } running GET comments/_mapping will get you "comment":{ "type":"text", "fields":{ "keyword":{ "type":"keyword", "ignore_above"

Cannot use “OR” with “NOT _exists_” in Kibana 6.8.0 search bar

自闭症网瘾萝莉.ら 提交于 2021-02-11 06:27:28
问题 I am trying to create one query in the Kibana search bar to retrieve some specific documents. The goal is to get the documents that either have the field "myDate" before 2019-10-08 or "myDate" does not exist. I have documents that meet one or the other condition. I started by creating this query : myDate:<=2019-10-08 OR NOT _exists_:myDate But no documents were returned. Since it did not work, I tried some other ways i found online : myDate:<=2019-10-08 OR NOT (_exists_:myDate) myDate:<=2019

问题 Thanks in advance for your help. I would like to reload some logs to customize additional fields. I have noticed that registry file in filebeat configuration keeps track of the files already picked. However, if I remove the content in that file, I am not getting the old logs back. I have tried also to change the timestamp of the source in registry file with no sucsess. What changes are needed to sent old logs from filebeat to logstash? How can I get the logs back? Update: This is the last log
