I have two containers running in an Ubuntu VM in Digital Ocean created from the following commands (Reference: https://www.youtube.com/watch?v=Imno51M24TQ&index=5&list=PLaDyYdZGRivhrKi56npbyFX2LTLs_--gq );
docker run --name db -it -p 3306:3306 mariadb
docker run --name mysql-client --link db:mysql mariadb sh -c ‘exec mysql -uroot -ptest -hmysql’
I’m trying to load test the database and monitor using J-Meter. I have J-Meter installed on the Ubuntu VM and executed the following command
jmeter -n -t DatabaseTest.JMX
However I’m receiving the following error
Error in NonGUIDriver java.lang.NullPointerException
Any tips on how to fix this? What other methods is there to monitor using load testing running containers?
Is cAdvisor a good tool to monitor my containers?
