venkata anil 8c094190ed rally cleanup manually 
Rally cleans up resources automatically at the end of testing.
However, we disable cleanup in rally sometimes during testing
and later try to manually delete these resources.

Cleaning up the resources at scale is very time consuming,
so we came up with a python process to speed up this activity.

To cleanup :

$ source browbeat/.rally-venv/bin/activate
$ source ~/overcloudrc
$ python browbeat/rally_cleanup.py

It spawns the user specified number of processes for cleanup.
Each process cleans up the provided resource (example, given
network). We are using python multiprocessing Pool with map,
which distributes list of resources (ex, networks) to processes
for deletion.

We also add retries to check and delete the left over resources
from previous iterations.

Usage
========
Run Browbeat performance tests from Undercloud
----------------------------------------------
::
$ ssh undercloud-root
[root@ospd ~]# su - stack
[stack@ospd ~]$ cd browbeat/
[stack@ospd browbeat]$ . .browbeat-venv/bin/activate
(browbeat-venv)[stack@ospd browbeat]$ vi browbeat-config.yaml # Edit browbeat-config.yaml to control how many stress tests are run.
(browbeat-venv)[stack@ospd browbeat]$ ./browbeat.py <workload> #rally, shaker or "all"
Running Shaker
---------------
Running Shaker requires the shaker image to be built, which in turn requires
instances to be able to access the internet. The playbooks for this installation
have been described in the installation documentation but for the sake of
convenience they are being mentioned here as well.
::
$ ansible-playbook -i hosts install/shaker_build.yml
.. note:: The playbook to setup networking is provided as an example only and
might not work for you based on your underlay/overlay network setup. In such
cases, the exercise of setting up networking for instances to be able to access
the internet is left to the user.
Once the shaker image is built, you can run Shaker via Browbeat by filling in a
few configuration options in the configuration file. The meaning of each option is
summarized below:
**shaker:**
:enabled: Boolean ``true`` or ``false``, enable shaker or not
:server: IP address of the shaker-server for agent to talk to (undercloud IP
by default)
:port: Port to connect to the shaker-server (undercloud port 5555 by default)
:flavor: OpenStack instance flavor you want to use
:join_timeout: Timeout in seconds for agents to join
:sleep_before: Time in seconds to sleep before executing a scenario
:sleep_after: Time in seconds to sleep after executing a scenario
:shaker_region: OpenStack region you want to use
:external_host: IP of a server for external tests (should have
``browbeat/util/shaker-external.sh`` executed on it previously and have
iptables/firewalld/selinux allowing connections on the ports used by network
testing tools netperf and iperf)
**scenarios:** List of scenarios you want to run
:\- name: Name for the scenario. It is used to create directories/files
accordingly
:enabled: Boolean ``true`` or ``false`` depending on whether or not you
want to execute the scenario
:density: Number of instances
:compute: Number of compute nodes across which to spawn instances
:placement: ``single_room`` would mean one instance per compute node and
``double_room`` would give you two instances per compute node
:progression: ``null`` means all agents are involved, ``linear`` means
execution starts with one agent and increases linearly, ``quadratic``
would result in quadratic growth in number of agents participating
in the test concurrently
:time: Time in seconds you want each test in the scenario
file to run
:file: The base shaker scenario file to use to override
options (this would depend on whether you want to run L2, L3 E-W or L3
N-S tests and also on the class of tool you want to use such as flent or
iperf3)
To analyze results sent to Elasticsearch (you must have Elasticsearch enabled
and the IP of the Elasticsearch host provided in the browbeat configuration
file), you can use the following playbook to setup some prebuilt dashboards for
you:
::
$ ansible-playbook -i hosts install/kibana-visuals.yml
Alternatively you can create your own visualizations of specific shaker runs
using some simple searches such as:
::
shaker_uuid: 97092334-34e8-446c-87d6-6a0f361b9aa8 AND record.concurrency: 1 AND result.result_type: bandwidth
shaker_uuid: c918a263-3b0b-409b-8cf8-22dfaeeaf33e AND record.concurrency:1 AND record.test:Bi-Directional
Correlating test run with logs
------------------------------
If filebeat is enabled in the browbeat configuration file and filebeat was previously installed by running:
::
$ ansible-playbook -i hosts common_logging/install_logging.yml
as explained in the installation documentation, then
By enabling filebeat logging within the browbeat configuration file, a playbook `ansible/common_logging/browbeat_logging.yml`
is run which appends browbeat_uuid to log messages and starts filebeat pre-browbeat workload run so that log messages have
browbeat uuid appended and clears the uuid from the configuration file and stops filebeat from sending more logs post-browbeat
workload run
Interpreting Browbeat Results
-----------------------------
By default results for each test will be placed in a timestamped folder `results/` inside your Browbeat folder.
Each run folder will contain output files from the various workloads and benchmarks that ran during that Browbeat
run, as well as a report card that summarizes the results of the tests.
Browbeat for the most part tries to restrict itself to running tests, it will only exit with a nonzero return code
if a workload failed to run. If, for example, Rally where to run but not be able to boot any instances on your cloud
Browbeat would return with RC 0 without any complaints, only by looking into the Rally results for that Browbeat run
would you determine that your cloud had a problem that made benchmarking it impossible.
Likewise if Rally manages to run at a snails pace, Browbeat will still exit without complaint. Be aware of this when
running Browbeat and take the time to either view the contents of the results folder after a run. Or setup Elasticsearch
and Kibana to view them more easily.
Working with Multiple Clouds
----------------------------
If you are running playbooks from your local machine you can run against more
than one cloud at the same time. To do this, you should create a directory
per-cloud and clone Browbeat into that specific directory:
::
[browbeat@laptop ~]$ mkdir cloud01; cd cloud01
[browbeat@laptop cloud01]$ git clone git@github.com:openstack/browbeat.git
...
[browbeat@laptop cloud01]$ cd browbeat/ansible
[browbeat@laptop ansible]$ ./generate_tripleo_hostfile.sh -t <cloud01-ip-address>
[browbeat@laptop ansible]$ ansible-playbook -i hosts (Your playbook you wish to run...)
[browbeat@laptop ansible]$ ssh -F ssh-config overcloud-controller-0 # Takes you to first controller
Repeat the above steps for as many clouds as you have to run playbooks against your clouds.
Compare software-metadata from two different runs
-------------------------------------------------
Browbeat's metadata is great to help build visuals in Kibana by querying on specific metadata fields, but sometimes
we need to see what the difference between two builds might be. Kibana doesn't have a good way to show this, so we
added an option to Browbeat CLI to query ElasticSearch.
To use :
::
$ python browbeat.py --compare software-metadata --uuid "browbeat-uuid-1" "browbeat-uuid-2"
Real world use-case, we had two builds in our CI that used the exact same DLRN hash, however the later build had a
10x performance hit for two Neutron operations, router-create and add-interface-to-router. Given we had exactly the
same DLRN hash, the only difference could be how things were configured. Using this new code, we could quickly identify
the difference -- TripleO enabled l3_ha.
Below is an example output of comparing metadata:

Compare performance of two different runs
------------------------------------------
Using the CLI the user can determine, run to run performance differences. This is a good tool for spot checking performance of an OpenStack
release.
You'll need to install extra dependencies for browbeat insights, which will
provide additional modules needed for providing insights.
To install :
::
$ source browbeat/.browbeat-venv/bin/activate
$ pip install .[insights]
To use :
::
$ python browbeat.py -q -u browbeat_uuid1 browbeat_uuid2
