Oslo.messaging Simulator¶
This section describes how to perform Message Queue Performance with Oslo.messaging Simulator tool.
Test environment preparation¶
To perform the test plan you will need to install oslo.messaging simulator.
The simulator tool depends on SciPy library which requires some mathematical packages to be installed into system.
To install on CentOS 7:
# yum install lapack-devel
To install on Ubuntu 14.04:
# apt-get install liblapack-dev gfortran
The simulator is distributed as part of library sources. It is recommended to be installed within virtual environment.
$ git clone https://git.openstack.org/openstack/oslo.messaging
$ cd oslo.messaging/
$ virtualenv .venv
$ source .venv/bin/activate
$ pip install -r requirements.txt
$ python setup.py install
$ pip install scipy
$ cd tools/
