For Spring Framework 5.0.1.RELEASE and Spring Boot 2.0.0.M6 We want to use the micrometer application monitoring, so wie included:
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('io.micrometer:micrometer-registry-prometheus')
Into our dependency set and create a controller with the following rest endpoints:
@RestController
@Timed
public class MyController {
@Autowired
private MyService service;
@RequestMapping(value = "/test", method = RequestMethod.GET)
public void test() {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
@RequestMapping(value = "/test/flux", method = RequestMethod.GET, produces = "application/stream+json")
public Flux<MyItem> getMyItems(@RequestParam Map<String, String> params) {
return this.service.getMyItems(params);
}
}
So we got the /test endpoint which is just waiting two seconds and we got the /test/flux endpoint which is returning a list of itmes.
Bot requests work. The only difference is that for the /test endpoint I get prometheus metrics and for the /test/flux endpoint I do not get any metrics:
http_server_requests_duration_seconds_count{exception="None",method="GET",status="200",uri="/get/test",} 1.0
http_server_requests_duration_seconds_sum{exception="None",method="GET",status="200",uri="/get/test",} 2.002811046
http_server_requests_duration_seconds_max{exception="None",method="GET",status="200",uri="/get/test",} 0.0
Do I have to configure something else to get that working for requests which are returning a Flux or is Flux yet not supported?
