Prometheus metrics - not found - java

I have spring boot application and i am using vertx.
I want to monitor the services and the jvm and for that i chose Prometheus.
This is my MonitoringConfig class:
#Configuration
public class MonitoringConfig {
#Bean
SpringBootMetricsCollector springBootMetricsCollector(Collection<PublicMetrics> publicMetrics) {
SpringBootMetricsCollector springBootMetricsCollector = new SpringBootMetricsCollector(publicMetrics);
springBootMetricsCollector.register();
return springBootMetricsCollector;
}
#Bean
public ServletRegistrationBean servletRegistrationBean() {
DefaultExports.initialize();
return new ServletRegistrationBean(new MetricsServlet(), "/prometheus");
}
}
And this are my dependencies:
<dependency>
<groupId>com.moelholm</groupId>
<artifactId>prometheus-spring-boot-starter</artifactId>
<version>1.0.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.prometheus/simpleclient -->

<artifactId>spring-hateoas</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
It shows no error in the app, but when i am trying to access http://localhost:8787/prometheus i am getting Not Found.
Also i have tried only with actuator and it still the same.
http://localhost:8787/actuator, http://localhost:8787/health and etc. Allways getting: Not found.
So my question is what can cause this and how can i fix this problem?

I think that some of the dependencies is causing the problem. Try removing one by one and you can notice where is the problem.
Also for monitoring vert.x application here is a good example that can be useful for you.
About the jvm metrics, add this in your start:
DefaultExports.initialize();
new DropwizardExports(SharedMetricRegistries.getOrCreate("vertx")).register();

Use OAuth library for Spring Boot

I'm trying to include the oauth library in Spring Boot. I don't know why, but it doesn't seem to be working. In any case, I cannot use the following libraries:
ProtectedResourceDetails cannot be resolved to a type
OAuthConsumerSupport cannot be resolved to a type
BaseProtectedResourceDetails cannot be resolved to a type
Pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.5.2.RELEASE</version>

</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-test</artifactId>
<scope>test</scope>
</dependency>
required libraries to use the following classes:
OAuthConsumerSupport oAuthConsumerSupport = new CoreOAuthConsumerSupport();
ProtectedResourceDetails is24ClientKeyDetails = createIs24ClientKeyDetails();
BaseProtectedResourceDetails protectedResourceDetails = new BaseProtectedResourceDetails();
These libraries are deprecated and most likely not compatible with your version of spring boot:
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.5.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
</dependency>
Here is the stack overflow post about this:
What is the replacement for the deprecated AuthorizationServer in Spring Security?
Here is a video on how to use the new spring security:

I tried many solutions:
Adjusted maven pom with freemarker exclusions and adding explicitly spring-context-support.
Added spring.freemarker.check-template-location: false
Added spring.freemarker.enabled: false
and none of these combinations were working for me, at every start of my Spring-Boot App I got the same error you mentioned.
Finally I found that just re-defining the suffix with:
spring
freemarker:
suffix: .ftl
and setting up:
#EnableAutoConfiguration(exclude = {FreeMarkerAutoConfiguration.class})
in my AppConfig class (the Class which contains the #Configuration annotation), my App is starting after that change.
I have to mention that I use Freemarker without template stored in my App but just using it as a runtime dependency (my Freemarker templates are just texts (Java String) passed in my Class Methods), then I don't really care about the file extensions. I do not want to use the Freemarker auto-configure and I just added the dependency explicitly:
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>${freemarker.version}</version>

Package my-commons comes from the internal repository of my company, but we have Maven's settings.xml configured for it, and it normally works in all other cases.
Any help on this would be highly appreciated.
Please check if the "my-commons" actually contains snapshots or only release artifacts. check if there is some other repo for snapshots and adapt you maven configuration accordingly. See here for reference how to do that: https://maven.apache.org/settings.html#Repositories

SpringBoot 1.5.x not writing to file at logging.file

I have a service that has loggers in a lot of places like this
private static final Logger LOGGER =

I have tried adding my own logback-spring.xml file that only writes to a file and that seems to only stop the the printing to the console but still it doesn't write to the file. Described here Spring Boot - no log file written (logging.file is not respected)
I have stepped through the code and noticed that the LoggingSystem class is setting the properties correctly. Also if I exclude starter-logging dependency like this
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
then the service log file is created but by the internal Java handler and it's in the wrong format. I want to use the Spring one because it can show more info when setting the log level to TRACE or DEBUG.
Has anyone else seen this problem and know how to make Spring write the service logs to that filed specified?
UPDATE
It seems the issue is coming from these dependencies
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-context</artifactId>
</dependency>
It seems any springframework.cloud dependency will cause the project to not create the logging.file file.
I found the problem and the solution.
I needed to put the logging properties like
logging.file=my-service.log
in a bootstrap.properties file. This file should be places in the resources directory where the application.properties file is.
It seems that when using the springframework.cloud dependency BootstrapApplicationListener is called first to initialize LogbackLoggingSystem class. Then since those properties are initialized then the application ignores them in the application.properties file.
More here https://github.com/spring-projects/spring-boot/issues/7099
