This article is about how to use fuse to monitor Hystrix Dashboard in springcloud. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Hystrix-dashboard is a tool for real-time monitoring of Hystrix. Through Hystrix Dashboard, we can directly see the request response time, request success rate and other data of each Hystrix Command. But if you only use Hystrix Dashboard, you can only see the service information in a single application, which is obviously not enough. We need a tool that allows us to aggregate data from multiple services in the system and display it on Hystrix Dashboard. This tool is Turbine.

Hystrix Dashboard

We changed it based on the circuit breaker sample project spring-cloud-consumer-hystrix and renamed it: spring-cloud-consumer-hystrix-dashboard.

1. Add dependencies

Org.springframework.cloud spring-cloud-starter-hystrix org.springframework.cloud spring-cloud-starter-hystrix-dashboard org.springframework.boot spring-boot-starter-actuator

These three packages must be added

2. Startup class

Start class add enable Hystrix Dashboard and fuse

@ SpringBootApplication@EnableDiscoveryClient@EnableFeignClients@EnableHystrixDashboard@EnableCircuitBreakerpublic class ConsumerApplication {public static void main (String [] args) {SpringApplication.run (ConsumerApplication.class, args);}}

3. Testing

When you visit http://localhost:9001/hystrix after starting the project, you will see the following interface:

There are some hints in the figure:

Cluster via Turbine (default cluster): http://turbine-hostname:port/turbine.stream Cluster via Turbine (custom cluster): http://turbine-hostname:port/turbine.stream?cluster=[clusterName]Single Hystrix App: http://hystrix-app:port/hystrix.stream

It roughly means that if you look at the default cluster using the first url, the specified cluster uses the second url, and the monitoring of a single application uses the last one, we only demonstrate a single application for the time being, so enter: http://localhost:9001/hystrix.stream in the input box, and then click monitor to go to the page.

If there is no request, Loading will be displayed first, and access to http://localhost:9001/hystrix.stream will continue to display ping.

If you request the service http://localhost:9001/hello/neo, you can see the monitoring effect. First, visit http://localhost:9001/hystrix.stream, which is shown as follows:

Ping:data: {"type":...} data: {"type":...}

Indicates that the monitoring results have been returned.

When you go to the monitoring page, the following figure is displayed:

In fact, it is the graphical display of the result returned by http://localhost:9001/hystrix.stream. The meaning of each metric on the Hystrix Dashboard Wiki is described in detail, as shown in the following figure:
