Java Spring Profiling with Spring Insight

We will be using Spring Insight to profile a Spring MVC application in Amazon EC2. As long as you are using Ubuntu, you should be able to follow this post.

Specs:

• Ubuntu Server 12.04.1 LTS
• m1.small instance
• a pre-existing Java Spring application deployed on tomcat7
• Java Open JDK 1.7

Being by connecting to you machine via ssh.

Download Spring Insight. Select the vfabric tc server developer edition instead of the springsource tool suite (STS). You will need to sign on an account in the VMware website. Use wget to fetch the file to your ubuntu instance.

wget {link to vfabric-tc-server-developer-2.9.2.RELEASE.zip}
cd /opt
mkdir /opt/tools
cd /opt/tools
unzip vfabric-tc-server-developer-2.9.2.RELEASE.zip
mv vfabric-tc-server-developer-2.9.2.RELEASE

Inside the vfabric-tc-server-developer-2.9.2.RELEASE folder, run

./tcruntime-instance.sh create insight -t insight

You will see

A folder called insight is created.

If you change into the insight directory, you will see a folder called webapps (this is almost same as the Tomcat directories). Copy your war file into this directory.

cd insight
cp {your_java_war_file} webapps/

Start the insight instance.

./tcruntime-ctl.sh insight start
