我正在寻找 Grails 3.x 的 yammer-metrics 插件的替代品，并找到了相同的 Grails Dropwizard Metrics。

我试图将它与我的示例应用程序（在 Grails 3.x 中）集成并遵循以下文档： http: //grails-plugins.github.io/grails-dropwizard-metrics/snapshot/index.html#_healthcheck_beans

在博客之后，我在 build.gradle 中添加了以下依赖项，即

compile "org.grails.plugins:dropwizard-metrics:1.0.0.BUILD-SNAPSHOT"

为了测试这一点，我用 index() 动作制作了 TestController，即

import grails.plugin.dropwizard.metrics.timers.Timed

class TestController {

    @Timed('test1')
    def index() {
        render 'ok'
    }
}

有了这个，运行应用程序并点击 /test/index 然后 /metrics，不再返回一个有效的 JSON，包含版本、gaugues、计数器、计时器标签等（如在http://grails-plugins.github.io中看到的/grails-dropwizard-metrics/snapshot/index.html#_exposing_metrics_data )

相反，它只是以这种格式返回 JSON：

}

在我的示例应用程序中，我也尝试在 resources.groovy 中注册 MetricRegistry bean，如下所示：

豆子 = { metricRegistry(MetricRegistry) }

但输出 JSON 仍然是相同的。

请让我缺少什么。提前致谢！
