I have list of metrics from Spring Boot Api but it doesn't contains http_* metrics
my pom.xml contains
<prometheus.version>0.1.0</prometheus.version>
....
<dependency>
<groupId>io.prometheus</groupId>
<artifactId>simpleclient_hotspot</artifactId>
<version>${prometheus.version}</version>
</dependency>
<dependency>
<groupId>io.prometheus</groupId>
<artifactId>simpleclient_servlet</artifactId>
<version>${prometheus.version}</version>
</dependency>
<dependency>
<groupId>io.prometheus</groupId>
<artifactId>simpleclient</artifactId>
<version>${prometheus.version}</version>
</dependency>
I made DefaultExports.initialize() and set bean
#Bean
SpringBootMetricsCollector springBootMetricsCollector(Collection<PublicMetrics> publicMetrics) {
SpringBootMetricsCollector springBootMetricsCollector = new SpringBootMetricsCollector(publicMetrics);
springBootMetricsCollector.register();
return springBootMetricsCollector;
}
then i get list of metrics from spring boot api but it does not contain htpp_ * metrics
like http_request_duration_microseconds
how can i get it?

So I was using Open Tracing to trace calls to the microservice. I used to do it the following way:
<dependency>
<groupId>io.opentracing</groupId>
<artifactId>opentracing-api</artifactId>
<version>0.31.0</version>
</dependency>
<dependency>
<groupId>io.opentracing.contrib</groupId>
<artifactId>opentracing-spring-cloud-starter</artifactId>
<version>0.1.13</version>
</dependency>
<dependency>
<groupId>io.jaegertracing</groupId>
<artifactId>jaeger-client</artifactId>
<version>0.31.0</version>
</dependency>
Then add following bean:
#Bean
public Tracer initTracer() {
Configuration.SamplerConfiguration samplerConfig = new Configuration.SamplerConfiguration().withType("const").withParam(1);
Configuration.ReporterConfiguration reporterConfig = Configuration.ReporterConfiguration.fromEnv().withLogSpans(true);
return Configuration.fromEnv("my-service").withSampler(samplerConfig).withReporter(reporterConfig).getTracer();
}
When running I usually get these span reported logs whenever an external request is given to the application.
But with open telemetry I cannot simply do this anymore. What is the correct way to simulate the behaviour?
I'm following Swagger Java example, but can't make it work with Spring Boot Camel.
I'm running Spring Boot Camel 3.4.0, and have next dependencies in pom.xml:

My Router.java is next:
String listenAddress = "192.168.0.100";
int listenPort = 8080;
restConfiguration()
.component("netty-http")
.scheme("http")
.host(listenAddress)
.bindingMode(RestBindingMode.auto)
.dataFormatProperty("prettyPrint", "true")
.port(listenPort)
.contextPath("/")
// add swagger api-doc out of the box
.apiContextPath("/api-doc")
.apiProperty("api.title", "User API").apiProperty("api.version", "1.2.3")
// and enable CORS
.apiProperty("cors", "true");
// this user REST service is json only
rest("/user").description("User rest service")
.consumes("application/json").produces("application/json")
.get("/{id}").description("Find user by id").outType(User.class)
.param().name("id").type(path).description("The id of the user to get").dataType("int").endParam()
.log("Swagger REST header id: ${header.id}");
If trying to GET http://192.168.0.100:8080/api-doc I'm getting 404.
This route above should print log in Camel terminal when using REST GET with http://192.168.0.100:8080/user/123 or am I wrong? Can't see what's missing.
The context path by default is set to /camel/, which means if rest of your configuration is correct, you should be able to see your api-docs at http://192.168.0.100:8080/camel/api-doc
To override it, you need to set the following property in your application.properties file.
camel.component.servlet.mapping.context-path= /*
For me adding the configuration :
In routes
String listenAddress = "localhost";
int listenPort = 8003;
restConfiguration()
.component("servlet")
.scheme("http")
.host(listenAddress)
.bindingMode(RestBindingMode.auto)
.dataFormatProperty("prettyPrint", "true")
.port(listenPort)
.contextPath("/")
// add swagger api-doc out of the box
.apiContextPath("/api-doc")
.apiProperty("api.title", "User API").apiProperty("api.version", "1.2.3")
// and enable CORS
.apiProperty("cors", "true");
In application.properties
server.port=8003
camel.component.servlet.mapping.context-path=/**
URI
http://localhost:8003/api-doc
I am using camel version : 3.9.0
This solution works fine !!!!
I'm using spring boot 2 to create a project and use websocket using reactive web dependency. My application is worked correctly until I add datarest dependency. after I add datarest dependency application give
' failed: Error during WebSocket handshake: Unexpected response code: 404
is any way to resolve this conflict?.

spring-boot-starter-data-rest brings spring-boot-starter-web as a transitive dependency (so basically Spring MVC). This makes Spring Boot configure your application as a Spring MVC web application.
Spring Data REST does not currently support Spring WebFlux (see this issue for more information on that).
Your only choice is to remove the Spring Data REST dependency, as you can't have both Spring MVC and Spring WebFlux in the same Spring Boot application.
I have a spring-boot-app with Actuator and Hystrix enabled.
Spring-Boot-Version: 1.3.1.RELEASE
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

<groupId>org.springframework.cloud</groupId>

When I add #HystrixCommandto some methods, the /metrics Endpoint shows all the metrics from hystrix:
gauge.hystrix.HystrixCommand.RestEndpoints.TestController.test.errorPercentage: 0,
gauge.hystrix.HystrixThreadPool.RestEndpoints.rollingMaxActiveThreads: 1,
...
Question:
How can I exclude the hystrix-metrics completely from the /metricsendpoint?
Update 1
I tried to exclude the ServoMetrics and SpectatorMetrics with these approaches:
1)
#EnableAutoConfiguration(exclude={ServoMetricsAutoConfiguration.class,
SpectatorMetricsAutoConfiguration.class} )
2)
#SpringBootApplication(exclude={ServoMetricServices.class, SpectatorMetricServices.class})
But both did not achieved the desired effect.
This issue was created and fixed. In snapshots you can now set the following:
hystrix.metrics.enabled=false.
If you don't want any other metrics, better solution would be to create your own MetricsRegistry. This way, any other future code changes (adding more jars with more in built metrics) would not affect.
#Configuration
public class MetricsConfiguration {
private MetricRegistry metricRegistry;
MetricsConfiguration() {
//avoid other metrics already registered
metricRegistry = new MetricRegistry();
}
}
Note: Creating a #Bean of type MetricRegistry would not help, as Spring autoconfigure will use this Bean object instead of MetricsRegistry object from MetricsDropwizardAutoConfiguration.java
Just taking Spring-Boot for a spin and decided to mix in Camel because I need some arcane Headers work in the rest client I am working on. Setting up the application was fine until I added the camel-http component to my POM, then I get this on init:
Exception in thread "main" org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
I've havent got the first idea of where to start to look for the problem. I gather Spring Boot will look up the classpath and try to wire stuff up, so is there a way for the to block the Camel packages from being acted on or something of the sort?
Complete log of the start up in this Gist
Here's my main aplication code:
#ComponentScan
#EnableAutoConfiguration

private static ApplicationContext ctx;
public static void main(String[] args) throws Exception {
ctx = SpringApplication.run(Application.class, args);
//Right outta Spring 4 docs
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}

// FIXME: ugly hack to allow some POC woek while wait for proper Camel/Spring4 unit tests fix.

The exception is telling you that Spring Boot thinks you want to build a web server, but can't find the right dependencies on the classpath. The most obvious reason for that in your case would be that the HTTP dependencies you added included Servlet APIs. I see no reason why you need that for a client app, but only you would know whether you need it or not. Maybe you can exclude it?
If you do need the Servlet dependencies and just want to explicitly tell Boot that you aren't creating a web application you can set the property spring.main.web_environment=false, or use the SpringApplication (or SpringApplicationBuilder) API directly to set the same flag. See docs here for background information.
