| <li>Foundation-metrics loads all MetricsInitializer implementations via the SPI mechanism. Implementers can use the getOrder in the MetricsInitializer to plan the execution order. The smaller the order number, the earlier it will be executed.</li> |
| <li>Metrics-core implements 3 types of MetricsInitializer:</li> |
| <li>DefaultRegistryInitializer: Instantiate and register spectator-reg-servo, set a smaller order, and ensure that it is executed before the following two types of MetricsInitializer</li> |
| <li>Meters Initializer: Statistics of data such as TPS, delay, thread pool, jvm resources, etc.</li> |
| <li>Publisher: Output statistics, built-in log output, and output via RESTful interface</li> |
| <li>Metrics-prometheus provides the ability to interface with prometheus</li> |

| <h1 id="fourth-business-customization">Fourth, business customization</h1> |
| <p>Because ServiceComb has initialized the registry's registry, the business no longer has to create a registry.</p> |
| <p>Implement the MetricsInitializer interface, define the business-level Meters, or implement a custom Publisher, and then declare your implementation through the SPI mechanism.</p> |
| <h3 id="1meters">1.Meters:</h3> |
| <p>Creating Meters capabilities is provided by spectator, available in the [netflix spectator] (https://github.com/Netflix/spectator) documentation</p> |
| <h3 id="2publisher">2.Publisher:</h3> |
| <p>Periodically output scenarios, such as log scenarios, subscribe to org.apache.servicecomb.foundation.metrics.PolledEvent via eventBus, PolledEvent.getMeters() is the statistical result of this cycle. |
| Non-periodic output scenarios, such as access through the RESTful interface, the statistical results of this cycle can be obtained through globalRegistry.iterator()</p> |
