Trail Setup - Web Applications

Setup easyTravel

Dynatrace provides a sample application called “easyTravel”

• Install Oracle Virtualbox
• Install a OS in Oracle Virtualbox (Debian/Ubuntu/Centos)
• Download easyTravel Demo
• execute “java -jar dynatrace-easytravel-linux-x86_64.jar”
• execute “/bin/bash installChromeDeps.sh” in < easytravel install dir>/resources directory. NOTE: you need root privileges to run this script.
• Run easyTravel run < easyTravel-InstallationDirectory>\weblauncher\weblauncher.sh
• Click on the scenario you want to run (e.g. “Standard”)
• Now all the tiers of easyTravel are starting up and when you run it for the first time easyTravel will populate the internal database with a good amount of test data - so this may take a minute or two for the first run.

To generate heavy load on the application go to the easyTravel launcher and switch to the Black Friday Scenario by clicking on the link “Black Friday”.

Install OneAgent

• Follow Install OneAgent on Linux

Ex:

• Follow the steps

• Execute: /bin/sh Dynatrace-OneAgent-Linux-xxxxx.sh –set-monitoring-mode=fullstack –set-host-group=MyProdEnv –set-app-log-content-access=true

Options:

1. To set monitoring type use --set-monitoring-mode=fullstack
   • fullstack –> Full stack observability monitoring
   • infra-only –> For infrastructure only
2. To assign a host to a host group use --set-host-group=MyHostGroup
3. To set custom host name use --set-host-name=MyHostName or create hostname.conf file in /var/lib/dynatrace/oneagent/agent/config and add the name.
4. OneAgent Communication endpoint --set-server=https://100.20.10.1:443
5. Tenant token --set-tenant-token=abcdefghij123456
6. Network zones: If you have different regions & setup active gate in different regions, if you do not want traffic to travel around the world, set different network zones and use --set-network-zone=your.network.zone
7. Proxy use --set-proxy=172.1.1.128:8080
8. Oneagent auto update use --set-auto-update-enabled=true
9. Custom host metadata use --set-host-property=AppName --set-host-property=Environment=Dev

Custom path

• Installation path use INSTALL_PATH
• To customize the log path, use the LOG_PATH parameter.

Setup custome Apps

Apache (Linux)

• Install Apache
• Change configurations according to requirement (For linux use: /var/www/html/index.html)
• Restart Apache services
• Generate traffic using watch curl http://localhost
• Go to Dynatrace UI
• Go to Services & check if Apache is visible.

Dynatrace UI

Apache (Docker)

• Install Docker
• Create Docker container, route port 80 to 8080 & link local file (docker.html) to apache file in the docker

Ex: docker run -dit --name sunil-web -p 8080:80 -v /home/sunil/Desktop/Sunil/website/:/usr/local/apache2/htdocs/ httpd:2.4

• Update docker.html file

• Access http://localhost:8080/docker.html

• Find docker container IP Address using docker command Ex: docker inspect --format '' sunil-web

• Generate traffic

• Find Apache running on Docker service in Dynatrace UI Services

Setup Tomcat

Below steps based on Debian based distributions

• Install Java / Openjdk (Please check tomcat documentation for supported Java versions based on tomcat version)
• Install Tomcat Ex steps:
  1. Create /opt/tomcat directory using mkdir /opt/tomcat
  2. Install openjdk using apt-get install openjdk-17-jdk
  3. Change directory cd /opt/tomcat
  4. Download tomcat using wget https://dlcdn.apache.org/tomcat/tomcat-10/v10.1.17/bin/apache-tomcat-10.1.17.tar.gz
  5. Extract tomcat using tar zxvf apache-tomcat-10.1.17.tar.gz
  6. move all files to /opt/tomcat using mv /opt/tomcat/apache-tomcat-10.1.17/* /opt/tomcat
  7. (optional) remove unnecessary files rm -rf /opt/tomcat/apache-tomcat-10.1.17*
  8. Execute tomcat startup /opt/tomcat/apache-tomcat-10.1.17/bin/startup.sh
  9. Open url http://localhost:8080 and Follow below page instructions

1. Generate traffic using watch curl http://localhost:8080/examples/servlets/servlet/helloworldexample
2. You will notice services & new application in Dynatrace Services & Dynatrace Web applications

Note: All monitoring data is encapsulated in a placeholder application called My web application. If you want to route traffic to different application (Ex: MyWeb) based on domain for Real User Monitoring, follow Application Detection Rules steps
