| <h1 id="metrics">应用性能监控（metrics）</h1> |
| <p>应用性能监控通过周期性的统计数据，帮助开发者分析业务性能瓶颈，在性能优化、故障定位的时候非常有帮助。应用性能监控的指标包括 |
| 请求各个环节的时延、线程池使用情况、连接池使用情况、CPU和网络使用情况等。</p> |
| <p>统计数据是一个周期性时效数据，只在统计周期内具有意义。可以选择通过 <code>REST</code> 接口查询实时的统计数据，也可以通过日志开关，将 |
| 统计数据输出到日志文件里面，帮助分析性能问题。</p> |
| <h2 id="_1">使用方法</h2> |
| <p>使用应用性能监控非常简单， 只需要在应用中包含相关的依赖包，通过配置项开启和关闭相关功能。 </p> |
| <ol> |
| <li>开启应用性能监控功能， 需要引入下面的依赖：<pre><code>``` |
| <dependency> |
| <groupId>org.apache.servicecomb</groupId> |
| <artifactId>metrics-core</artifactId> |
| </dependency> |
| ``` |
| </code></pre> |
| </li> |
| </ol> |
| <p>通过在 <code>microservice.yaml</code> 中增加下面的配置项，就可以将性能统计数据输出到日志文件中。</p> |
| <pre><code> ``` |
| servicecomb: |
| metrics: |
| window_time: 60000 |
| invocation: |
| latencyDistribution: 0,1,10,100,1000 |
| Consumer.invocation.slow: |
| enabled: true |
| msTime: 1000 |
| Provider.invocation.slow: |
| enabled: true |
| msTime: 1000 |
| publisher.defaultLog: |
| enabled: true |
| endpoints.client.detail.enabled: true |
| ``` |
| </code></pre> |
| <p>上述配置开启了慢调用检测，如果存在慢调用，则会立即输出相应日志：</p> |
| <pre><code> ``` |

| <h2 id="prometheus">集成Prometheus</h2> |
| <p><a href="https://prometheus.io/">Prometheus</a> (普罗米修斯)是一个名字非常酷的开源监控系统。</p> |
| <p>它支持多维度的指标数据模型，服务端通过HTTP协议定时拉取数据后，通过灵活的查询语言，实现监控的目的。</p> |
| <p>servicecomb的应用性能监控功能支持对接Prometheus,首先需要在您的业务项目中加入如下依赖:</p> |
| <pre><code> ``` |
| <dependency> |
| <groupId>org.apache.servicecomb</groupId> |
| <artifactId>metrics-prometheus</artifactId> |
| </dependency> |
| ``` |
| </code></pre> |
| <p>然后在 microservice.yaml 中增加下面的配置项:</p> |
| <pre><code> ``` |
| servicecomb: |
| metrics: |
| prometheus: |
| address: ${ip}:${port} |
| ``` |
| </code></pre> |
| <p>该配置项是设置普罗米修斯框架监听的端口,您只需使用浏览器访问对应的ip地址加该端口即http://ip:port/metrics 就可以获得如下格式的监控数据:</p> |

| <ul> |
| <li>实现原理</li> |
| </ul> |
| <p><img alt="" src="../assets/metrics/logicDiagram.png" /></p> |
| <pre><code>1. 基于[netflix spectator](https://github.com/Netflix/spectator) |
| 2. Foundation-metrics通过SPI机制加载所有MetricsInitializer实现，实现者可以通过MetricsInitializer中的getOrder规划执行顺序，order数字越小，越先执行。 |
| 3. Metrics-core实现3类MetricsInitializer： |
| 1. DefaultRegistryInitializer: 实例化并注册spectator-reg-servo，设置较小的order，保证比下面2类MetricsInitializer先执行 |
| 2. Meters Initializer: 实现TPS、时延、线程池、jvm资源等等数据的统计 |
| 3. Publisher: 输出统计结果，内置了日志输出，以及通过RESTful接口输出 |
| 4. Metrics-prometheus提供与prometheus对接的能力 |
| </code></pre> |
| <ul> |
| <li>业务定制</li> |
| </ul> |
| <p>因为ServiceComb已经初始化了servo的registry，所以业务不必再创建registry。实现MetricsInitializer接口，定 |
| 义业务级的Meters，或实现定制的Publisher，再通过SPI机制声明自己的实现即可。</p> |
| <p>1.Meters</p> |
| <pre><code>创建Meters能力均由spectator提供，可查阅[netflix spectator](https://github.com/Netflix/spectator)文档 |
| </code></pre> |
| <p>2.Publisher</p> |
| <pre><code>周期性输出的场景，比如日志场景，通过eventBus订阅org.apache.servicecomb.foundation.metrics.PolledEvent，PolledEvent.getMeters()即是本周期的统计结果 |
| 非周期性输出的场景，比如通过RESTful接口访问，通过globalRegistry.iterator()即可得到本周期的统计结果 |
| </code></pre> |
