+****************
+Run with Ansible
+****************
+
+QTIP benchmarking tasks are built upon `Ansible`_ playbooks and roles. If you are familiar with Ansible, it is possible
+to run it with ``ansible-playbook`` command.
+
+.. _Ansible: https://www.ansible.com/
+
+Create workspace
+================
+
+There is a playbook in ``tests/integration`` used for creating a new workspace for QTIP benchmarking::
+
+ cd qtip/tests/integration
+ ansible-playbook workspace-create.yml
+
+You will be prompted for required information for the Pod under test::
+
+ (qtip) ➜ integration git:(master) ✗ ansible-playbook workspace-create.yml
+ name of the pod under test (used in reporting) [qtip-pod]:
+ scenario deployed in the pod: [default]:
+ installer type of the pod (apex|fuel|other) [fuel]:
+ master host/vm of the installer (accessible by `ssh <hostname>`): f5
+ workspace name (new directory will be created) [workspace]:
+
+ PLAY [localhost] ***************************************************************
+
+ TASK [qtip-workspace : generating workspace] ***********************************
+
+ PLAY RECAP *********************************************************************
+ localhost : ok=0 changed=0 unreachable=0 failed=0
+
+
+You may hit ``Enter`` to accept default value
+
+NOTE: if this playbook is moved to other directory, configuration in ``ansible.cfg`` needs to be updated accordingly.
+The ansible roles from QTIP, i.e. ``<path_of_qtip>/resources/ansible_roles`` must be added to ``roles_path`` in
+`Ansible configuration file`_. For example::
+
+ roles_path = ../../resources/ansible_roles
+
+.. _Ansible configuration file:
+
+Executing benchmark
+===================
+
+Before executing the setup playbook, make sure `~/.ssh/config` has been configured properly so that you can login the
+**master node** "directly". Skip next section, if you can login with ``ssh <master-host>`` from localhost,
+
+SSH access to master node
+-------------------------
+
+It is common that the master node is behind some jump host. In this case, ssh option ``ProxyCommand`` and ``ssh-agent``
+shall be required.
+
+Assume that you need to login to deploy server, then login to the master node from there. An example configuration is
+as following::
+
+ Host fuel-deploy
+ HostName 172.50.0.250
+ User root
+
+ Host fuel-master
+ HostName 192.168.122.63
+ User root
+ ProxyCommand ssh -o 'ForwardAgent yes' apex-deploy 'ssh-add && nc %h %p'
+
+If several jumps are required to reach the master node, we may chain the jump hosts like below::
+
+ Host jumphost
+ HostName 10.62.105.31
+ User zte
+ Port 22
+
+ Host fuel-deploy
+ HostName 172.50.0.250
+ User root
+ ProxyJump jumphost
+
+ Host fuel-master
+ HostName 192.168.122.63
+ User root
+ ProxyCommand ssh -o 'ForwardAgent yes' apex-deploy 'ssh-add && nc %h %p'
+
+NOTE: ``ProxyJump`` is equivalent to the long ``ProxyCommand`` option, but it is only available since OpenSSH 7.3
+
+Setup testing environment
+-------------------------
+
+Run the setup playbook to generate ansible inventory of system under test by querying the slave nodes from the installer
+master::
+
+ cd workspace
+ ansible-playbook setup.yml
+
+Currently, QTIP supports automatic discovery from `apex`_ and `fuel`_
+
+.. _apex: https://wiki.opnfv.org/display/apex
+.. _fuel: https://wiki.opnfv.org/display/fuel
+
+It will update the ``hosts`` and ``ssh.cfg``
+
+Run the tests
+-------------
+
+Run the benchmarks with the following command::
+
+ ansible-playbook run.yml
+
+CAVEAT: QTIP will install required packages in system under test.
+
+Inspect the results
+-------------------
+
+The test results and calculated output are stored in ``results``::
+
+ current/
+ node-2/
+ arithmetic/
+ metric.json
+ report
+ unixbench.log
+ dpi/
+ ...
+ node-4/
+ ...
+ qtip-pod-qpi.json
+ qtip-pod-20170425-1710/
+ qtip-pod-20170425-1914/
+ ...
+
+The folders are named as ``<pod_name>-<start_time>/`` and the results are organized by *hosts* under test. Inside each
+host, the test data are organized by metrics as defined in QPI specification.
+
+For each metrics, it usually includes the following content
+
+* log file generated by the performance testing tool
+* metrics collected from the log files
+* reported rendered with the metrics collected
+
+Teardown the test environment
+-----------------------------
+
+QTIP will create temporary files for testing in system under test. Execute the teardown playbook to clean it up::
+
+ ansible-playbook teardown.yml
