带有 Dropwizard 指标的 grails 中的注释不起作用

Question

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

我在`BuildConfig.groovy'中有以下内容

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'

我正在尝试将数据发布到Graphite 服务器，在本地运行。 我用石墨报告器配置了一个控制器，如下所示。当我运行应用程序时它不会报告任何内容，我试图找出我哪里出错了，或者如果有另一种方法（例如使用 spring AOP）请告诉我

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

查看您的代码，我发现了一个不同之处：

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

这意味着您的 Graphite 报告器每秒触发一次，但控制台报告器仅每 5 秒触发一次。可能您的测试程序在这 5 秒结束之前就已经存在。因此，您可以在 main() 方法中添加 Thread.sleep(6000) 或减少控制台报告器的报告间隔以匹配 Graphite 报告器。我试过了，它有效。 ;-)
