我想为一个简单的乒乓应用程序启用指标监控,在那里我可以看到两个节点之间发送了多少数据包。
测量的指标应该通过事件总线推送并由网站使用,提供仪表板。复制自vertx examples on Github
使用以下命令启动应用
发件人:
vertx run de.avm.boundary.Receiver -cluster -cp target/vertx-ping-pong-3.3.3-fat.jar
接收机
package de.avm.boundary;
import io.vertx.core.AbstractVerticle;
import io.vertx.core.Handler;
import io.vertx.core.Vertx;
import io.vertx.core.http.HttpServer;
import io.vertx.core.json.JsonObject;
import io.vertx.core.logging.Logger;
import io.vertx.core.logging.LoggerFactory;
import io.vertx.ext.dropwizard.MetricsService;
import io.vertx.ext.web.Router;
import io.vertx.ext.web.handler.StaticHandler;
import io.vertx.ext.web.handler.sockjs.BridgeOptions;
import io.vertx.ext.web.handler.sockjs.PermittedOptions;
import io.vertx.ext.web.handler.sockjs.SockJSHandler;
public class Sender extends AbstractVerticle {
Logger logger = LoggerFactory.getLogger(getClass().getSimpleName());
@Override
public void start() {
Vertx.currentContext().config();
System.out.println("START SENDER VERTICLE DEPLOYMENT ID: " + deploymentID());
BridgeOptions bridgeOptions = new BridgeOptions().
addOutboundPermitted(
new PermittedOptions().
setAddress("metrics-sender")
).addOutboundPermitted(new PermittedOptions().
setAddressRegex("metrics-receiver")
);
Router router = Router.router(vertx);
router.route("/eventbus/*").handler(SockJSHandler.create(vertx).bridge(bridgeOptions));
router.route().handler(StaticHandler.create());
HttpServer httpServer = vertx.createHttpServer();
httpServer.requestHandler(router::accept).listen(8080);
//why is the service object null ??
MetricsService service = MetricsService.create(vertx.eventBus());
System.out.println("Metrics-Service: " + service);
vertx.setPeriodic(100, new Handler<Long>() {
@Override
public void handle(Long timerID) {
vertx.eventBus().publish("ping-address", "more news! at: " + System.currentTimeMillis());
}
});
vertx.setPeriodic(1000, new Handler<Long>() {
@Override
public void handle(Long timerID) {
JsonObject metrics = service.getMetricsSnapshot(vertx);
vertx.eventBus().publish("metrics-sender", metrics);
System.out.println("Metrics: " + metrics);
}
});
}
}
不提供任何指标。

如何启用指标?
答案 0 :(得分:1)
通过在另一场战争中改变开始的应用程序,特别是Sender和Receiver Verticles来解决问题。
对我来说最好的解决方案是使用
启动应用程序<强>发件人:强>
java -jar target/vertx-ping-pong-3.3.3-Sender-fat.jar -cluster -Dvertx.metrics.options.enabled=true
<强>接收机强>
java -jar target/vertx-ping-pong-3.3.3-Receiver-fat.jar -cluster -Dvertx.metrics.options.enabled=true
陷阱是,你必须告诉maven,尤其是它们的主要类别的阴影插件。我通过在pom.xml中的属性部分中定义占位符并在maven构建执行期间传递主Vericle的名称来实现此目的。
mvn package -DmainClass=Sender
这也会导致放置一个带有目标文件夹的fat-jar,其中传递的参数的名称包含在文件名中。
此处修改后的pom.xml
