<p>在IoTDB运行过程中，我们希望对IoTDB的状态进行观测，以便于排查系统问题或者及时发现系统潜在的风险。能<strong>反映系统运行状态的一系列指标</strong>就是metrics。</p> <h2 id="_2-什么场景下会使用到metrics"><a href="#_2-什么场景下会使用到metrics" class="header-anchor">#</a> 2. 什么场景下会使用到metrics?</h2> <p>那么什么时候会用到metrics呢？下面列举一些常见的场景。</p> <ol><li><p>系统变慢了</p> <p>系统变慢几乎是最常见也最头疼的问题，这时候我们需要尽可能多的信息来帮助我们找到系统变慢的原因，比如：</p> <ul><li>JVM信息：是不是有FGC？GC耗时多少？GC后内存有没有恢复？是不是有大量的线程？</li> <li>系统信息：CPU使用率是不是太高了？磁盘IO是不是很频繁？</li> <li>连接数：当前连接是不是太多？</li> <li>接口：当前TPS是多少？各个接口耗时有没有变化？</li> <li>线程池：系统中各种任务是否有积压？</li> <li>缓存命中率</li></ul></li> <li><p>磁盘快满了</p> <p>这时候我们迫切想知道最近一段时间数据文件的增长情况，看看是不是某种文件有突增。</p></li> <li><p>系统运行是否正常</p> <p>此时我们可能需要通过错误日志的数量、集群节点的状态等指标来判断系统是否在正常运行。</p></li></ol> <h2 id="_3-什么人需要使用metrics"><a href="#_3-什么人需要使用metrics"

IoTDB都有哪些metrics?</h2> <p>目前，IoTDB对外提供一些主要模块的metrics，并且随着新功能的开发以及系统优化或者重构，metrics也会同步添加和更新。</p> <h3 id="_4-1-名词解释"><a href="#_4-1-名词解释" class="header-anchor">#</a> 4.1. 名词解释</h3> <p>在进一步了解这些指标之前，我们先来看几个名词解释：</p> <ul><li><p>Metric Name</p> <p>指标名称，比如logback_events_total表示日志事件发生的总次数。</p></li> <li><p>Tag</p> <p>每个指标下面可以有0到多个分类，比如logback_events_total下有一个<code>level</code>的分类，用来表示特定级别下的日志数量。</p></li></ul> <h3 id="_4-2-数据格式"><a href="#_4-2-数据格式" class="header-anchor">#</a> 4.2. 数据格式</h3> <p>IoTDB对外提供JMX和Prometheus格式的监控指标，对于JMX，可以通过<code>org.apache.iotdb.metrics</code>获取metrics指标。</p> <p>接下来我们以Prometheus格式为例对目前已有监控项进行说明。</p> <h3 id="_4-3-iotdb-默认指标"><a href="#_4-3-iotdb-默认指标" class="header-anchor">#</a> 4.3.
