New Relic for Spring Boot - spring

Question

Recently, we convert a tomcat/spring app to spring boot. Everything is working fine apart from new relic. Is there a way I can easily config new relic with spring boot project. I don't want to hard code the location of new relic agent jar path, then run the spring boot project with the path.
edit: Spring boot project is with maven

Answer 1

You can include NewRelic Maven dependency and use maven-dependency-plugin to unpack in into your target/classes directory, which allows Maven to include it into final Jar file. Then you have to add Premain-Class attribute into manifest file and you can use your application jar as -javaagent source. You can find details on my blog post

Answer 2

Step by step instructions
Extract the files from the newrelic java agent archive.
Create a directory named newrelic in the root of your application.
Place the newrelic.jar from the archive in the above created newrelic folder
Place the newrelic.yml YAML config file in the above created newrelic folder.
Update the values in newrelic.yml as below.
license_key: 'your license key'
app_name: ‘Your application name’
Run you application by using the option javaagent
java -javaagent:newrelic\newrelic.jar -jar yourapplication.jar
-javaagent option needs to be before the -jar so the agent can start

Answer 3

I was stuck with the same issue, here is what I figured out. I implemented the 2nd way for my applications.
There are 3 ways to integrate New Relic with a Spring Boot Application-
Using the Java Agent provided by New Relic
Using New Relic's Micrometer Dependency
Micormeter's New Relic Dependency
1. Configuration using Java Agent Provided By New Relic
Download the Java Agent from this URL- https://docs.newrelic.com/docs/release-notes/agent-release-notes/java-release-notes/
Extract it.
Modify the newrelic.yml file inside the extracted folder to include your
license_key:
app_name:
Create a SpringBoot application with some REST endpoints.
Build the application.
Navigate to the root path where you have extracted the newrelic java agent.
Enter this command
java -javagent:<path to your new relic jar>\newrelic.jar -jar <path to your application jar>\<you rapplication jar name>.jar
To view the application metrics-
Log in to your New Relic account.
Go to Explorer Tab.
Click on Services-APM
You can see the name of your application(which you had mentioned in the newrelic.yml file) listed there.
Click on the application name.
The dashboard should look something like this.
Using New Relic's Micrometer Dependency is the preferred way to do it.
2. Configuration using New Relic's Micrometer Dependency
Add this dependency
<dependency>
<groupId>com.newrelic.telemetry</groupId>
<artifactId>micrometer-registry-new-relic</artifactId>
<version>0.7.0</version>
</dependency>
Modify the MicrometerConfig.java class to add your API Key and Application name.
import java.net.InetAddress;
import java.net.UnknownHostException;
import org.springframework.boot.actuate.autoconfigure.metrics.CompositeMeterRegistryAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.metrics.MetricsAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.metrics.export.simple.SimpleMetricsExportAutoConfiguration;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.boot.autoconfigure.AutoConfigureBefore;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.newrelic.telemetry.Attributes;
import com.newrelic.telemetry.micrometer.NewRelicRegistry;
import com.newrelic.telemetry.micrometer.NewRelicRegistryConfig;
import java.time.Duration;
import io.micrometer.core.instrument.config.MeterFilter;
import io.micrometer.core.instrument.util.NamedThreadFactory;
#Configuration
#AutoConfigureBefore({ CompositeMeterRegistryAutoConfiguration.class, SimpleMetricsExportAutoConfiguration.class })
#AutoConfigureAfter(MetricsAutoConfiguration.class)
#ConditionalOnClass(NewRelicRegistry.class)
public class MicrometerConfig {
#Bean
public NewRelicRegistryConfig newRelicConfig() {
return new NewRelicRegistryConfig() {
#Override
public String get(String key) {
return null;
}
#Override
public String apiKey() {
return "your_api_key"; // for production purposes take it from config file
}
#Override
public Duration step() {
return Duration.ofSeconds(5);
}
#Override
public String serviceName() {
return "your_service_name"; // take it from config file
}
};
}
#Bean
public NewRelicRegistry newRelicMeterRegistry(NewRelicRegistryConfig config) throws UnknownHostException {
NewRelicRegistry newRelicRegistry = NewRelicRegistry.builder(config)
.commonAttributes(new Attributes().put("host", InetAddress.getLocalHost().getHostName())).build();
newRelicRegistry.config().meterFilter(MeterFilter.ignoreTags("plz_ignore_me"));
newRelicRegistry.config().meterFilter(MeterFilter.denyNameStartsWith("jvm.threads"));
newRelicRegistry.start(new NamedThreadFactory("newrelic.micrometer.registry"));
return newRelicRegistry;
}
}
Run the application.
To view the Application metrics-
Log in to your New Relic account.
Go to Explorer Tab.
Click on Services-OpenTelemetry
You can see the name of your application(which you had mentioned in the MicrometerConfig file) listed there.
Click on the application name.
The dashboard should look something like this.
