I am trying to send custom metrics to Splunk APM using micrometer dependencies. after adding the dependencies and setting the application properties I am Seeing metrics in the APM dashboard but Service, host_name, process_id, and runtime information are not available in SignalFx when using a micrometer.
I have added the below dependencies and application properties
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-signalfx</artifactId>
<version>1.9.3</version>
</dependency>
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-core</artifactId>
<version>1.9.3</version>
</dependency>
Application Properties
management.metrics.export.signalfx.access-token={my org token}
management.metrics.export.signalfx.enabled=true
management.metrics.export.signalfx.uri={my org signalfx uri}
management.metrics.export.signalfx.source=suryatestspringapp
I have attached the image where Service, host_name, process_id, and runtime information is missing.
Can someone help to fix this issue?

I am trying to combine these 2 tutorials - Confluence Hello World Macro & Azure keyvault quick start:
https://developer.atlassian.com/server/framework/atlassian-sdk/create-a-confluence-hello-world-macro/
https://learn.microsoft.com/en-us/azure/key-vault/secrets/quick-create-java?tabs=azure-cli
After having added the 2 Azure dependencies to the pom.xml of the maven project and running atlas-mvn clean package I receive an error message about 3 banned dependencies.
I looked for the newest Azure packages at the maven portal. Then it was reduced to one.
Found Banned Dependency: org.slf4j:slf4j-api:jar:1.7.25
Then I added added exclusions to the dependency section:
This resulted that the build ran successfully, however, the Confluence plugin produces a runtime error:
java.lang.NoClassDefFoundError
Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/Logger
at com.azure.security.keyvault.secrets.SecretClientBuilder.(SecretClientBuilder.java:110)
Can you please help, how can I achieve this?

The above error indicates that JVM is not able to found org/slf4j/Logger class in your application's path.The simplest reason for this error is the missing Slf4j.jar file.
If the problem is caused due to the missing slf4j.jar file then you can fix it by adding a relevant version of slf4j.jar into your path.
Use the latest version of the jar in which version of the JAR file you should add will depend upon the application.
In Maven , you can also add the following dependency in your pom.xml file to download sl4j.jar
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.36</version>
</dependency>

I'm building a simple reactive web application ( Following Josh long's tech talk ) Simply put I have reactive web, r2dbc and h2 as dependencies.
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-r2dbc</artifactId>
</dependency>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
So I expect spring would configure everything for me( It does for Josh ). But I get error saying not being able to connect to a database and there is a suggestion asking to include h2(which I already have). What am I doing wrong here?
Description:
Failed to configure a ConnectionFactory: 'url' attribute is not specified and no embedded database could be configured.
Reason: Failed to determine a suitable R2DBC Connection URL
Action:
Consider the following:
If you want an embedded database (H2), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
Ok it was missing r2dbc-h2 dependency. This happened because I didn't add r2dbc when I created the project with start.spring.io then added it and inspect the pom but only copied spring-boot-starter-data-r2dbc.
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-h2</artifactId>
<scope>runtime</scope>
</dependency>
Still bit confusing though. Spring boot says it looks in to the class path and auto configure dependencies but seems like sometimes it need given combination of dependencies.
For my automation project, i am trying to integrate cassandra to spring boot jpa using datastasx driver and

I suspect you were getting other exceptions like OperationTimedOutException when the driver attempts to connect to the nodes in the list but continually failed.
The driver generates a query plan which is a list of nodes to contact for an app query. The driver cycles through this list one node at a time until it is able to connect to all of them. After it has tried to connect to all nodes in the list (which all failed), the driver returns NoHostAvailableException: All host(s) tried for query failed.
The most common causes for this are (1) network connectivity issues, or (2) nodes being down or unresponsive. There is a good chance that the cluster nodes are listening on a different IP address that you are connecting to.
It sounds like you're trying this out for the first time and you might find it easier to just focus on coding your app by connecting to Astra so you don't have to worry about the DB side of things. There's a Spring sample app that you could look at that will get you up and running in literally a few minutes. Cheers!
My goal is to use the jax-rs client to connect to a back-end inside the MobileFirst Java adapter, but I'm really stuck and need help.
The code that throws the exception:
javax.ws.rs.client.Client client = javax.ws.rs.client.ClientBuilder.newClient();
The Exception that was thrown:
java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder`
The code is inside the Java adapter on MobileFirst server version 8.0 deployed on IBM Liberty server.
jaxrsClient-2.0 and jaxrs-2.0 features are enabled in the server feature manager in server.xml.
<feature>jaxrs-2.0</feature>
<feature>jaxrsClient-2.0</feature>
The application class is loaded configured like this:
<application id="mfp" name="mfp" location="mfp-server.war" type="war">
<classloader delegation="parentLast" apiTypeVisibility="spec, ibm-api, third-party"></classloader>
</application>

Please, help!
I was working on a similar requirement, I did try out a number of combinations before resolving the exception.
I am not sure why liberty is not providing with client implementation classes..
you could try including jersey-client through maven pom.xml..
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.23.1</version>
</dependency>
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>org.eclipse.persistence.moxy</artifactId>
<version>2.6.1</version>
</dependency>
In Server.xml remove the features
<feature>jaxrs-2.0</feature>
<feature>jaxrsClient-2.0</feature>
and just add below feature.
<feature>beanValidation-1.1</feature>
Liberty IS providing a client implementation, but the parentLast classloader delegation is preventing it from being used.
It would appear that MobileFirst is packaging Jersey, in which case, the Liberty's JAX-RS features should be disabled so that Jersey is used instead. This may require you to change how dependencies are declared in the maven/gradle artifacts.
This looks like a bug in WebSphere Liberty that was fixed in 16.0.0.4. If the classes that are creating a new instance of the JAX-RS client is packaged in an OSGi bundle (either in an OSGi application or as part of a Liberty feature), then the JAX-RS client runtime cannot find the META-INF/services file that specifies Liberty's JAX-RS client implementation class (based on CXF) -- and so the JAX-RS runtime will fall back to the Jersey implementation, which won't be found unless you package it with your app.
The fix for this issue is described here. Basically, Liberty makes the META-INF/services file available to OSGi bundles.
The fix from Suresh worked. I just needed to add more dependencies in my pom.xml though. I don't think I need Moxy here.. will optimize further.

I have recently switched from using Eclipse to IntelliJ, and am preferring the experience.
However, the IDE is not understanding any of the Annotations. I am using Spring #Autowired annotation as well as some of the Spring-WS annotations and the IDE is telling me that they are unresolved.
When the project is built using Maven, it builds fine, and the Annotations are recognised in Eclipse.
Im sure this is a simple setup thing, but cannot find any information on how to set it up.
As Peter said, when correctly importing the Maven project the dependencies should be correctly recognized. The IntelliJ manual has a section on how to import a Maven project.
For the record, in our project pom, we have the following dependencies:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>3.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-ws-core</artifactId>
<version>2.0.1.RELEASE</version>
</dependency>
The former two have been present already before implementing a web service, so they may not be required strictly for web services.
