This guide will serve as a first step to familiarize the user with how to
run QTIP the first time when the user clones QTIP on to their host machine.
In order to clone QTIP please follow the instructions in the
installation.rst located in docs/userguide/installation.rst.

QTIP Directory structure:
-------------------------

The QTIP directory has been sectioned off into multiple folders to facilitate
 segmenting information into relevant categories. The folders that concern
 the end user are `test_cases/` and `test_list/`.

**test_cases/:**

This folder is used to store all the config files which are used to setup the
 environment prior to a test. This folder is further divided into opnfv pods
 which run QTIP. Inside each pod there are folders which contain the config
 files segmented based on test cases. Namely, these include, `Compute`,
 `Network` and `Storage`. The default folder is there for the end user who
 is interested in testing their infrastructure but arent part of a opnfv pod.

The structure of the directory for the user appears as follows
::

  test_cases/default/compute
  test_cases/default/network
  test_cases/default/storage

The benchmarks that are part of the QTIP framework are listed under these
folders. An example of the compute folder is shown below.
Their naming convention is <BENCHMARK>_<VM/BM>.yaml
::

  dhrystone_bm.yaml
  dhrystone_vm.yaml
  whetstone_vm.yaml
  whetstone_bm.yaml
  ssl_vm.yaml
  ssl_bm.yaml
  ramspeed_vm.yaml
  ramspeed_bm.yaml
  dpi_vm.yaml
  dpi_bm.yaml

The above listed files are used to configure the environment. The VM/BM tag
distinguishes between a test to be run on the Virtual Machine or the compute
node itself, respectively.


**test_list/:**

This folder contains three files, namely `compute`, `network` and `storage`.
These files list the benchmarks are to be run by the QTIP framework. Sample
compute test file is shown below
::

  dhrystone_vm.yaml
  dhrystone_bm.yaml
  whetstone_vm.yaml
  ssl_bm.yaml

The compute file will now run all the benchmarks listed above one after
another on the environment. `NOTE: Please ensure there are no blank lines
in this file as that has been known to throw an exception`.

Preparing a config file for test:
---------------------------------

We will be using dhrystone as a example to list out the changes that the
user will need to do in order to run the benchmark.

Dhrystone on Compute Nodes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^

QTIP framework can run benchmarks on the actual compute nodes as well. In
order to run dhrystone on the compute nodes we will be editing the
dhrystone_bm.yaml file.

::

  Scenario:
    benchmark: dhrystone
    host: machine_1, machine_2
    server:

The `Scenario` field is used by to specify the name of the benchmark to
run as done by `benchmark: dhrystone`. The `host` and `server` tag are
not used for the compute benchmarks but are included here to help the
user `IF` they wish to control the execution. By default both machine_1
and machine_2 will have dhrystone run on them in parallel but the user
can change this so that machine_1 run dhrystone before machine_2. This
will be elaborated in the `Context` tag.

::

  Context:
    Host_Machines:
      machine_1:
        ip: 10.20.0.6
        pw:
        role: host
      machine_2:
        ip: 10.20.0.5
        pw:
        role: host

     Virtual_Machines:

The `Context` tag helps the user list the number of compute nodes they want
 to run dhrystone on. The user can list all the compute nodes under the
 `Host_Machines` tag. All the machines under test must be listed under the
 `Host_Machines` and naming it incrementally higher. The `ip:` tag is used
 to specify the IP of the particular compute node. The `pw:` tag can be left
 blank because QTIP uses its own key for ssh. In order to run dhrystone on
 one compute node at a time the user needs to edit the `role:` tag. `role:
 host` for machine_1 and `role: server` for machine_2 will allow for
 dhrystone to be run on machine_1 and then run on machine_2.

    Benchmark: "dhrystone"

        ''' This test will run the dhrystone benchmark in parallel  on

The above field is purely for a description purpose to explain to the user
the working of the test and is not fed to the framework.

        machine_1 and machine_2.\n

Dhrystone on Virtual Machine:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
To run dhrystone on the VMs we will be editing dhrystone_vm.yaml file.
Snippets on the file are given below.

::

  Scenario:
  benchmark: dhrystone
  host: virtualmachine_1, virtualmachine_2
  server:


The `Scenario` field is used by to specify the name of the benchmark to
run as done by `benchmark: dhrystone`. The `host` and `server` tag are
not used for the compute benchmarks but are included here to help the
user `IF` they wish to control the execution. By default both
virtualmachine_1 and virtualmachine_2 will have dhrystone run on them
in parallel but the user can change this so that virtualmachine_1 run
dhrystone before virtualmachine_2. This will be elaborated in the
`Context` tag.
::

  Context:
    Host_Machines:

    Virtual_Machines:
      virtualmachine_1:
        availability_zone: compute1
        public_network: 'net04_ext'
        OS_image: QTIP_CentOS
        flavor: m1.large
        role: host
      virtualmachine_2:
        availability_zone: compute2
        public_network: 'net04_ext'
        OS_image: QTIP_CentOS
        flavor: m1.large
        role: host

The `Context` tag helps the user list the number of VMs and their
characteristic. The user can list all the VMs they want to bring up
under the `Virtual_Machines:` tag. In the above example we will be
bringing up two VMs. One on Compute1 and the other on Compute2. The
user can change this as desired `NOTE: Please ensure you have the
necessary compute nodes before listing under the 'availability_zone:'
tag`. The rest of the options do not need to be modified by the user.

Running dhrystone sequentially (Optional):
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In order to run dhrystone on one VM at a time the user needs to edit
the `role:` tag. `role: host` for virtualmachine_1 and `role: server`
for virtualmachine_2 will allow for dhrystone to be run on
virtualmachine_1 and then run on virtualmachine_2.

::

  Test_Description:
    Test_category: "Compute"
    Benchmark: "dhrystone"
    Overview:
    This test will run the dhrystone benchmark in parallel on
    virtualmachine_1 and virtualmachine_2

the user the working of the test and is not fed to the framework.

Commands to run the Framework:
------------------------------

In order to start QTIP on the default lab please use the following commands (asssuming you have prepared the config files in the test_cases/default/ directory and listed the intended suite in the test_list/<RELEVANT-SUITE-FILE>):

First step is to export the necessary information to the environment.
::

  source get_env_info.sh -n <INSTALLER_TYPE> -i <INSTALLER_IP>

for running qtip on an openstack deployed using FUEL with the Installer IP 10.20.0.2
::

   source get_env_info.sh -n fuel -i 10.20.0.2

This will generate the `opnfv-creds.sh` file needed to use the python clients for keystone, glance, nova, and neutron.
::

  source opnfv-creds.sh

Running QTIP on the using `default` as the pod name and for the `compute` suite
::

  python qtip.py -l default -f compute

Running QTIP on the using `default` as the pod name and for the `network` suite
::

  python qtip.py -l default -f network

Running QTIP on the using `default` as the pod name and for the `storage` suite
::

  python qtip.py -l default -f network

Results:
--------
QTIP generates results in the `results/` directory are listed down under the particularly benchmark name. So all the results for dhrystone would be listed and time stamped.
