我想啓用度量監控一個簡單的乒乓應用程序，在這裏我可以看到兩個節點之間發送了多少數據包。vertx運行在羣集啓用
度量的度量標準應推送到事件總線上並由網站使用，提供儀表板。從vertx examples on Github
啓動的應用程序複製用下列命令
發件人：
vertx run de.avm.boundary.Sender -cluster -cp target/vertx-ping-pong-3.3.3-fat.jar -Dvertx.metrics.options.enabled=true
接收機
vertx run de.avm.boundary.Receiver -cluster -cp target/vertx-ping-pong-3.3.3-fat.jar
不提供任何指標。

如何啓用指標？
您發佈的指標，但你永遠不使用它們。或者你沒有在你的地方發佈代碼。 –
在這個問題的第一部分中提到了官方Vertx示例的鏈接。使用儀表板網站。但主要的問題是，啓動應用程序時沒有啓用這些指標。 似乎沒有考慮給定選項「-Dvertx.metrics.options.enabled = true」。 – AdemC
