Tomcat performance testing

First checkout latest version of this repository on all machines

test -e ~/src/tomcat-bench || git clone https://github.com/tgrabiec/tomcat-bench ~/src/tomcat-bench
cd ~/src/tomcat-bench
git fetch
git checkout -f ${TOMCAT_BENCHMARK_VERSION_REF:-origin/master}

Preparing host machine

Run

./setup-host.sh

Prepare fedora image

TODO: Describe how to prepare base fedora image

Start your fedora image:

cd ~/src/osv
sudo scripts/run.py -m2g -nv -b bridge0 -i ~/fedora/fedora.img
GUEST_IP=10.0.0.176

Upload tomcat deployment to fedora guest

cd apps/tomcat/upstream
zip -r tomcat.zip apache-tomcat-7.0.42/
scp tomcat.zip root@${GUEST_IP}:~

Perform the following steps in fedora guest.

Unzip the package:

$ cd ~
$ rm -rf apache-tomcat-*/
$ unzip tomcat.zip
$ ln -s apache-tomcat-7.0.42 tomcat

Create init script and shutdown:

$ cd /etc/init.d
$ cat > tomcat
#!/bin/bash
set -e
case $1 in
    'start')
        export JAVA_OPTS="-Xmx2g -Xms2g"
        cd /root/tomcat/bin
        ./startup.sh 2>&1 > /var/log/tomcat.log < /dev/null &
    ;;
esac
$ chmod +x tomcat 
$ cd ../rc3.d
$ ln -s ../init.d/tomcat S99tomcat
$ shutdown now

Save image backup

cp ~/fedora/fedora.img ~/fedora/fedora.img.original 

Preparing load driver machine

Run

sudo ./setup.sh

Running the test

Restore image from the backup and start the guest. It is important to do it before each test because the guest file system fills up very quickly. If the image was not restored the consecutive samples would not be independent.

For OSv:

cd ~/src/osv
cp usr.img.original build/release/usr.img && \
sudo scripts/run.py -m4g -nv -b bridge0

For Fedora:

cp ~/fedora/fedora.img.original ~/fedora/fedora.img && \
sudo scripts/run.py -m4g -nv -b bridge0 -i ~/fedora/fedora.img

Read the IP of OSv and assign to GUEST_IP variable on load driver machine.

Start the test on load driver machine:

./perform-one-test.sh

Kill the guest.

After test

Restore system configuration on load driver machine

cd ~/src/tomcat-bench
sudo ./restore_sys_conf.sh
rm ./restore_sys_conf.sh

Obtaining test variables

Host:

cd ~/src/osv
echo OSV_VERSION=$(scripts/osv-version.sh)
cd apps
echo APPS_VERSION=$(git rev-parse HEAD)

cd ~/src/FrameworkBenchmarks
echo TEST_APP_VERSION=$(git rev-parse HEAD)

echo QEMU_VERSION=$(qemu-system-x86_64 -version | sed -r 's/.*version ([0-9.]+).*/\1/')

Load driver:

cd ~/src/tomcat-bench
echo BENCHMARK_VERSION=$(git rev-parse HEAD)
