Vert.x core provides a Service Provide Interface (SPI) for collecting metrics. The Dropwizard implementation collects these metrics in a Dropwizard registry that can be used for reporting in other system or can be queried via the Dropwizard MetricsService.
This example is a UI monitoring dashboard built on top of the Dropwizard metrics implementation.
The Java monitoring dashboard example The Groovy monitoring dashboard example The JavaScript monitoring dashboard example The Ruby monitoring dashboard example
The dashboard uses the vertx-web eventbus bridge to push metrics periodically on the event bus. The metrics are retrieved from the MetricsService in Json format.
Run the dashboard either in your IDE or on the command line, then open your browser and hit link:http://localhost:8080 to see the dashboard
You can also launch the example using the vertx cli as follows:
# compile the example, you need to have built example-utils before. mvn clean package # java vertx run io.vertx.example.metrics.dashboard.Dashboard -cp target/metrics-examples-3.2.0.jar:src/main/java/io/vertx/example/metrics/dashboard -Dvertx.metrics.options.enabled=true # javascript cd src/main/js/io/vertx/example/metrics/dashboard vertx run dashboard.js -cp ./../../../../../../../../target/metrics-examples-3.2.0.jar:. -Dvertx.metrics.options.enabled=true # groovy cd src/main/groovy/io/vertx/example/metrics/dashboard vertx run dashboard.groovy -cp ./../../../../../../../../target/metrics-examples-3.2.0.jar:. -Dvertx.metrics.options.enabled=true # ruby cd src/main/rb/io/vertx/example/metrics/dashboard vertx run dashboard.rb -cp ./../../../../../../../../target/metrics-examples-3.2.0.jar:. -Dvertx.metrics.options.enabled=true
