Dropwizard度量标准不起作用的grails注释

Question

我正在为带有注释的grails应用程序配置dropwizard度量标准。使用指标，AspectJ的插件（https://github.com/astefanutti/metrics-aspectj）

在`BuildConfig.groovy”

compile 'io.astefanutti.metrics.aspectj:metrics-aspectj:1.1.0' 
compile 'io.dropwizard.metrics:metrics-core:3.1.0' 
compile 'io.dropwizard.metrics:metrics-graphite:3.1.2' 
compile 'io.dropwizard.metrics:metrics-annotation:3.1.2' 

在这里，我尝试将数据上传到服务器Graphite，本地运行，我有以下。 我已经配置了一个控制器如下与石墨记者。当我运行的应用程序也不会报告任何东西，我试图找出在我去错了，还是请让我知道，如果有一个是另一种方法（例如，使用Spring AOP）

import com.codahale.metrics.ConsoleReporter 
import com.codahale.metrics.MetricFilter 
import com.codahale.metrics.MetricRegistry 
import com.codahale.metrics.SharedMetricRegistries 
import com.codahale.metrics.annotation.Metered 
import com.codahale.metrics.annotation.Timed 
import com.codahale.metrics.graphite.Graphite 
import com.codahale.metrics.graphite.GraphiteReporter 
import io.astefanutti.metrics.aspectj.Metrics 

import java.util.concurrent.TimeUnit 

@Metrics(registry = "graphiteregistry2") 
class GlassdoorController { 


    final MetricRegistry registry = new MetricRegistry(); 

    GlassdoorController() { 

     final Graphite graphite = new Graphite(new InetSocketAddress("127.0.0.1", 2003)); 

     final GraphiteReporter reporter = GraphiteReporter.forRegistry(registry) 
       .prefixedWith("grails.example.com") 
       .convertRatesTo(TimeUnit.SECONDS) 
       .convertDurationsTo(TimeUnit.MILLISECONDS) 
       .filter(MetricFilter.ALL) 
       .build(graphite); 
     reporter.start(1, TimeUnit.SECONDS); 

     ConsoleReporter reporter1 = ConsoleReporter.forRegistry(registry) 
       .convertRatesTo(TimeUnit.SECONDS) 
       .convertDurationsTo(TimeUnit.MILLISECONDS) 
       .build(); 
     reporter1.start(5, TimeUnit.SECONDS) 

     SharedMetricRegistries.add("graphiteregistry2",registry); 
     log.info(SharedMetricRegistries.getOrCreate("graphiteregistry2")); 
    } 

    @Metered(name = "reviewspage") 
    @Timed(name = "reviewspagetimed") 
    def reviews() { 

     //business logic 

    } 

Answer 1

看你的代码，我发现了一个差异：

reporter.start(1, TimeUnit.SECONDS); 
// ... 
reporter1.start(5, TimeUnit.SECONDS) 

这意味着您的石墨记者激发每一秒，但控制台仅记者每隔5秒。可能你的测试程序在5秒钟之前就已经存在了。因此，您可以将Thread.sleep(6000)添加到您的main()方法中，或者减少控制台记者与石墨记者相匹配的报告间隔。我试过了，它有效。 ;-)
