DevOpsSchool Posted November 1, 2023 Share Posted November 1, 2023 Step 1 – Install JDK https://www.devopsschool.com/blog/complete-guide-of-java-installation-in-linux/#Download_and_Install_JDKJRE_11_in_Ubuntu Step 2 – Install & Start Tomcat https://www.devopsschool.com/blog/tomcat-install-and-configuration-tutorial-and-guide/#Method_1_-_Install_and_Configuration_Tomcat_in_Any_Linux_using_Zip_file Step 3 – Install your apps Lets use Tomcat’s default example app only. You may have permission issues for accessing http://18.210.16.76:8080/examples/ which can be fixed by following commands below $ cd /opt/apache-tomcat-9.0.82/webapps/examples $ find . -name context.xml $ vi ./META-INF/context.xml Step 4 – Install NewRelic Infra Agent & APM Agent https://www.devopsschool.com/blog/newrelic-infrastructure-monitoring-linux-vitural-machine-using-newrelic-agent/ NewRelic Infra Agent would detect the Tomcat and Java automatically and try to configure APM Java Agent as per the image as below; root@ip-172-31-58-86:/etc/newrelic-infra/integrations.d# ls docker-config.yml java-dynamic-attach.yml root@ip-172-31-58-86:/etc/newrelic-infra/integrations.d# more java-dynamic-attach.yml integrations: - name: java-dynamic-attach exec: ./dynamic-attach.sh working_dir: /etc/newrelic-java interval: 60s timeout: 1200s integration_user: root root@ip-172-31-58-86:/etc/newrelic-infra/integrations.d# Step 5 -(Manual) Install NewRelic APM Java Agent Alternative curl -Ls https://download.newrelic.com/install/newrelic-cli/scripts/install.sh | bash && sudo NEW_RELIC_API_KEY=NRAK-32EHABRB7444 NEW_RELIC_ACCOUNT_ID=3404444 /usr/local/bin/newrelic install -n java-agent-installer Manual way to set Newrelic APM Agent in Tomcat $ cd /opt $ curl -O https://download.newrelic.com/newrelic/java-agent/newrelic-agent/current/newrelic-java.zip $ unzip newrelic-java.zip $ cd newrelic $ mv newrelic.yml newrelic.yml-bkp $ vi newrelic.yml # COPY PASTE from Download newrelic.yml $ chmod -R 755 . $ cd /opt/ $ cd apache-tomcat-9.0.73 $ cd bin $ vi catalina.sh export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/opt/newrelic/newrelic/newrelic.jar \ -Dnewrelic.config.file=/path/to/newrelic.yml \ -Dnewrelic.environment=production \ -Dnewrelic.appname=MyApp \ -Dnewrelic.verbose=true \ -Dnewrelic.config.log_file_path=/path/to/newrelic.log" $ ./shutdown.sh $ ./startup.sh $ ps -eaf | grep newrelic.jar The CATALINA_OPTS environment variable is used to set Java options for the Tomcat server. The option -javaagent:/opt/newrelic/newrelic/newrelic.jar is used to load the New Relic Java agent, which enables monitoring of your Tomcat application using New Relic APM. If you are looking for other options to set in CATALINA_OPTS to configure the New Relic Java agent, some common options include: -Dnewrelic.config.file=<path to newrelic.yml>: This option can be used to specify the path to the New Relic configuration file, which contains settings such as application name, license key, and logging configuration. -Dnewrelic.environment=<environment name>: This option can be used to specify the name of the environment in which your application is running, such as “production” or “staging”. -Dnewrelic.appname=<application name>: This option can be used to specify the name of your application as it will appear in the New Relic APM dashboard. -Dnewrelic.verbose=true: This option can be used to enable verbose logging for the New Relic Java agent. -Dnewrelic.config.log_file_path=<path to log file>: This option can be used to specify the path to the New Relic log file. Step 6 – Access the apps You may create a Traffic on App using Jmeter as below; Step 7 – Verify a APM apps on NewRelic Dashboard The post Newrelic APM- Install and Configure using Tomcat & Java Agent Tutorials appeared first on DevOpsSchool.com.
