Introduction

The playbooks and the roles provide a sample application that can be instrumented using AppDynamics. The instrumentation can be done manually or via playbooks. For a manual instrumentation, you deploy the supercars application without AppDynamics.

For the instrumentation, you can use an AppDynamics trial account:

This Wiki assumes that you are using CentOS7 as operating system.

Installation of needed packages

sudo yum install unzip vim nmap
sudo yum update -y nss curl libcurl

Creation of user and group for appd

sudo useradd appd
sudo groupadd appd
sudo usermod -a -G appd appd
sudo usermod -a -G appd tomcat
sudo usermod -a -G appd root

Create directory for AppDynamics

sudo mkdir -p /opt/appd/machine_agent
sudo mkdir -p /opt/appd/java_agent
sudo mkdir -p /opt/appd/db_agent

Download the appdynamics agent via terminal or on the webpage

You will need and appdynamics account in order to access the webpage

Further, you might need to adjust the agent version in the statements below. Just go on the download portal, select the respective agent and copy the link. The link can be used in the following curl statements

TOKEN=\`curl -X POST -d '{"username": "USER","password": "PWD","scopes": ["download"]}' https://identity.msrv.saas.appdynamics.com/v2.0/oauth/token | sed s/\\"/\\|/g | awk 'BEGIN{FS="|"}{print $10}'\`
curl -L -O -H "Authorization: Bearer $TOKEN" "https://download.appdynamics.com/download/prox/download-file/machine-bundle/4.5.16.2357/machineagent-bundle-64bit-linux-4.5.16.2357.zip"
curl -L -O -H "Authorization: Bearer $TOKEN" "https://download.appdynamics.com/download/prox/download-file/sun-jvm/4.5.16.28759/AppServerAgent-4.5.16.28759.zip"
curl -L -O -H "Authorization: Bearer $TOKEN" "https://download.appdynamics.com/download/prox/download-file/db-agent/4.5.5.985/db-agent-4.5.5.985.zip"

Unzip Agents to AppDynamics directory

sudo unzip machineagent-bundle-64bit-linux-4.5.16.2357.zip -d /opt/appd/machine_agent
sudo unzip AppServerAgent-4.5.16.28759.zip -d /opt/appd/java_agent
sudo unzip db-agent-4.5.5.985.zip -d /opt/appd/db_agent
sudo chown -R appd:appd /opt/appd/
sudo chmod -R u=rwx,g=rwx,o=rx /opt/appd/

Login as Tomcat user and start server

sudo su - tomcat
cd /opt/tomcat/apache-tomcat-8.0.30/bin/
./catalina.sh start

Configure java agent

sudo su -
touch /opt/tomcat/apache-tomcat-8.0.30/bin/setenv.sh
chmod +x /opt/tomcat/apache-tomcat-8.0.30/bin/setenv.sh
chown tomcat /opt/tomcat/apache-tomcat-8.0.30/bin/setenv.sh
chgrp tomcat /opt/tomcat/apache-tomcat-8.0.30/bin/setenv.sh
echo 'export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/opt/appd/java_agent/javaagent.jar -Dappdynamics.agent.uniqueHostId=RAVELLO_VM"' \> /opt/tomcat/apache-tomcat-8.0.30/bin/setenv.sh

sudo vim /opt/appd/java_agent/conf/controller-info.xml
  • set <controller-host>ACCOUNT.saas.appdynamics.com</controller-host> (see controller DNS)
  • set <controller-port>443</controller-port>
  • set <controller-ssl-enabled>true</controller-ssl-enabled>
  • set <application-name>APPNAME</application-name>
  • set <tier-name>TOMCAT</tier-name>
  • set <node-name>RAVELLO</node-name>
  • set <account-name>ACCOUNT</account-name> (see Settings->License->Top-Tab: Account -> Name)
  • set <account-access-key>KEY</account-access-key> (see Settings->License->Top-Tab: Account -> Access Key)

Restart Tomcat

sudo su - tomcat
cd /opt/tomcat/apache-tomcat-8.0.30/bin/
./catalina.sh stop
./catalina.sh run (to see if the agent starts correctly, if not check setenv.sh)
./catalina.sh stop
./catalina.sh start

Check if the agent started successfully

grep AppDynamics /opt/tomcat/apache-tomcat-8.0.30/logs/catalina.out (output: Started AppDynamics Java Agent Successfully)
vi /opt/appd/java_agent/ver4.5.16.28759/logs/RAVELLO/agent.*.log

Check Java Agent in Controller

  • Check Top-Tab: Applications, Side-Tab: Tiers and Nodes (agent must pop-up even w/o traffic)
  • Check Setting: AppDynamics Agents, App Server Agent (find your unique host-id)
  • Generate traffic by clicking around in the application http://IP:8080/Cars_Sample_App/angular/index.html#/
  • Check Top-Tab: applications, Side-Tab Application Dashboard (compare Flow-Map)

Configure Server Agent

sudo vim /opt/appd/machine_agent/conf/controller-info.xml
  • set <controller-host>ACCOUNT.saas.appdynamics.com</controller-host> (see controller DNS)
  • set <controller-port>443</controller-port>
  • set <controller-ssl-enabled>true</controller-ssl-enabled>
  • set <unique-host-id>RAVELLO_VM</unique-host-id>
  • set <account-access-key>KEY</account-access-key> (see Settings->License->Top-Tab: Account -> Access Key)
  • set <account-name>ACCOUNT</account-name> (see Settings->License->Top-Tab: Account -> Name)

set PasswordAuthentication yes
unset PasswordAuthentication no (e.g. use comment)
