Message Load Simulator for Ceilosca

This code has been customized from the oslo.messaging simulator.

The message loader sends messages to notifications.info and it
simulates the instance creation/delete for nova, the volume
create and delete from cinder and image update and delete.

The Private/Public shell scripts are running some plausible
test cases for a "scale" down simulation of a private/public
cloud environment with tenants and resources distribution.

ceilosca message simulator
========
This is a message generator simulator cloned from oslo.messaging
### Installation Instructions
1. Create a virtual environment where to run the simulator.
virtualenv simulator
2. Activate the virtual environment.
source simulator/bin/activate
3. Install oslo.message
pip install oslo.messaging
4. Run the simulator
python ceilosca-message-simulator.py --url rabbit://stackrabbit:password@localhost notify-client -m 1 -s nova -a create
Note: The simulator has three main parameters:
-m number of message to be published
-s service. Currently nova, cinder and glance are supported.
-a action. Currently create and delete are supported.
