Spring Cloud - Monitoring Gateway Application

For monitoring of the Gateway or for accessing various routes, predicates, etc., we can enable the actuator in the project. For doing that, let us first update the pom.xml to contain the actuator as a dependency.

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

For monitoring, we're enabling the actuator. So, here is how it would look like −

spring.application.name=restaurant-gateway-service

server.port=8084
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

management.endpoint.gateway.access=UNRESTRICTED
management.endpoints.web.exposure.include=gateway

Now, to list all the routes, we can hit: http://localhost:8084/actuator/gateway/routes

[
  {
    "predicate": "Paths: [/customer/**], match trailing slash: true",
    "route_id": "b8f0a6a6-eb31-469c-acf0-2cb9f51f7aa1",
    "filters": [],
    "uri": "http://localhost:8080/customer-service",
    "order": 0
  },
  {
    "predicate": "Paths: [/restaurant/**], match trailing slash: true",
    "route_id": "18b0ba68-3533-412c-b138-bc61b5b48e18",
    "filters": [],
    "uri": "http://localhost:8080/restaurant-service",
    "order": 0
  }
]
