public class MyHealthCheck extends NamedHealthCheck {

    @Inject
    private MyService service;

    @Override
    protected Result check() throws Exception {
        if (service.isOk()) {
            return Result.healthy();
        } else {
            return Result.unhealthy("Service is not ok");
        }
    }

    @Override
    public String getName() {
        return "my-service";
    }
}
