<h1>3. elk日志系统<a class="headerlink" href="#elk" title="Permalink to this headline"></a></h1>
<p>ELK组合是日志系统的经典组合。但是Logstash是java程序，占用内存资源比较大，前端将其换成轻量级的filebeat。haproxy放在主节点上做代理转发。</p>
<p>filebeat（日志收集）+ elasticsearch（日志存储搜索）+kibana（ui展示）+haproxy(代理转发)</p>
<div class="section" id="id1">
<h2>3.1. 安装<a class="headerlink" href="#id1" title="Permalink to this headline"></a></h2>

<p>filebeat使用源码放在主机上编译。 elk三个工程使用官方下载的tar.gz的包。都是java程序，直接就能运行。</p>
<p>繁星2代已编译好filebeat，其他平台需按照下面步骤编译：</p>

<h3>3.3.1. quick start<a class="headerlink" href="#quick-start" title="Permalink to this headline"></a></h3>
<p>Discover是查看、搜索日志的主要页面。如果有filebeat上报日志，第一次进入Discover会自动跳转，创建Index Patterns。</p>
<img alt="_images/elk-01.png" src="_images/elk-01.png" />
<img alt="_images/elk-02.png" src="_images/elk-02.png" />
<p>创建完毕后，在Discover中可以看到日志内容了，鼠标移到message，点add添加到“selected fields”中，日志内容看起来会清晰些。</p>
<img alt="_images/elk-03.png" src="_images/elk-03.png" />
<p>Management-&gt;Elasticsearch-&gt;Index Management中会自动生成类似“filebeat-7.0.0-alpha1-2018.09.29”的行。</p>
<p>进入Management-&gt;Kibana-&gt;Index Patterns可查看、删除、重新创建Index Patterns</p>
<p>仅以上配置，利用搜索栏和Add a filter， 以主机、文件名、时间、关键字等等组合条件，就能满足绝大多数需求。</p>
<p>其他使用技巧在下面补充</p>

<div class="section" id="kibana">
<h3>3.3.2. kibana页面上的日志搜索技巧<a class="headerlink" href="#kibana" title="Permalink to this headline"></a></h3>
<p>kikana Discover页面的搜索栏支持的查询语法名叫Lucene query。elasticsearch底层使用Lucene，api和kibana都支持Lucene语法。</p>
<p>lucene query语法参考：<a class="reference external" href="https://blog.csdn.net/feifantiyan/article/details/54411183">https://blog.csdn.net/feifantiyan/article/details/54411183</a></p>
<p>下面列出几个使用实例：</p>
<ul class="simple">
<li>查找beat.name为8.133的设备上日志文件路径中包含”Ops/2018-9-30”的日志</li>
</ul>
<div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>source:?*<span class="se">\/</span>Ops<span class="se">\/</span><span class="m">2018</span>-09-30?* AND beat.name:8.133
