AB benchmark and plotting

Small script to execute a apache benchmark ab from one host to other.

The scripts are designed for benchmark tsuru routers, and compare between hipache+nginx vs. vulcand.

It will gather metrics of request time and CPU in the target so they can be later plot using gnuplot.

Useful scripts to manage VMs on a IaaS: AWS, GCE, etc... Stop all vms, start them, etc..

Choose between the existing VPCs in a given region and stop all the VMs running there:

aws_stop_vms_by_vpc.sh [region]

	require "erb"

	class BigIpConfigurator
	@@resources = {} # Hash with all the resources defined

	# Define a resource, adding it to the list
	def self.resource(name, defaults, &block)
	@@resources[name] = {
	:defaults => defaults,
	:block => block

	# using VirtualBox version $VBOX_VERSION

	FROM boot2docker/boot2docker
	RUN apt-get install p7zip-full

	RUN mkdir -p /vboxguest && \
	cd /vboxguest && \
	curl -L -o vboxguest.iso http://download.virtualbox.org/virtualbox/$VBOX_VERSION/VBoxGuestAdditions_$VBOX_VERSION.iso && \
	7z x vboxguest.iso -ir'!VBoxLinuxAdditions.run' && \
	sh VBoxLinuxAdditions.run --noexec --target . && \
