ONAP Policy Framework: Standalone installation in Virtual Machine

Install & Configure VisualVM

VisualVM needs to be installed in the virtual machine having policy framework. It will be used to monitor CPU, Memory, GC for drools PDP while stability test is running.

Install visualVM

sudo apt-get install visualvm

Login to docker container (using root)

docker exec -e -it -u 0 drools su - root

Run few commands to configure permissions

cd /usr/lib/jvm/java-8-openjdk-amd64/bin/ 

touch visualvm.policy 

vi visualvm.policy 

Add the following in visualvm.policy


grant codebase "file:/usr/lib/jvm/java-8-openjdk-amd64/lib/tools.jar" {
   permission java.security.AllPermission;
};


chmod 777 visualvm.policy


exit

Login to docker container (using policy)

docker exec -e -it -u 0 drools su - policy

Run following commands to start jstatd using port 1111

cd /usr/lib/jvm/java-8-openjdk-amd64/bin/ 


./jstatd -p 1111 -J-Djava.security.policy=visualvm.policy  &


exit

Login to VM using graphical interface in separate terminal window.

ssh -X <user>@<VM-IP-ADDRESS>

Open visualVM

visualvm &

Connect to jstatd & remote drools PDP JVM

1. Right click on "Remote" in the left panel of the screen and select "Add Remote Host..."

2. Enter the IP address of drools docker container. Run the following command to check the IP address of drools container in VM.

   Code Block
   docker inspect --format '{{ .NetworkSettings.Networks.docker_default.IPAddress}}' drools

3. Right click on IP address, select "Add jstatd Connection..."
4. In "jstatd Connections" tab, enter port 1111 and click OK.
5. Right click on IP address, select "Add JMX Connection..."
6. Enter the drools docker container IP Address (from step 2) <IP address>:9991 ( for example - 172.18.0.7:9991) and click OK.
7. Double click on the newly added nodes under "Remote" to start monitoring CPU, Memory & GC.

• HTTP Request Defaults -  used to store HTTP request details like Server Name or IP, Port, Protocol etc.

• User Defined Variables -  used to store following parameters.

  Name	Description	Default Value
  size	Indicates the maximum number of VNF instances. Used for generating VNF IDs.	2000
  wait	Wait time after each request so that the same gets processed by engine (in milliseconds)	500

Important Note: There is wait introduced after sending every ONSET, Response, Request messages to drools PDP so that it is able to process the message before getting the next one. If needed, the wait time can be suitably adjusted based on the setup and time taken by drools PDP to process the messages.
