Sanjay Chari da7b97c08a Google Sheets : Add support for run comparison

This patch adds support to pass multiple Rally
result json files as arguments to the Google Sheet
generation script. This helps in comparison between results
of different runs.

Usage

Run Browbeat performance tests from Undercloud

For Running the workloads from Undercloud

$ ssh undercloud-root
[root@undercloud ~]# su - stack
[stack@undercloud ~]$ cd browbeat/
[stack@undercloud browbeat]$ . .browbeat-venv/bin/activate
(.browbeat-venv)[stack@undercloud browbeat]$ vi browbeat-config.yaml # Edit browbeat-config.yaml to control how many stress tests are run.
(.browbeat-venv)[stack@undercloud 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.yml 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.yml 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.yml 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

Example output from running this CLI command

python browbeat.py -q -u 6b50b6f7-acae-445a-ac53-78200b5ba58c 938dc451-d881-4f28-a6cb-ad502b177f3b

We can see from the output above that we also provide the user with some metadata regarding the two runs, like the amount version and the number of runs each UUID contained.

Cleanup Rally resources

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

Cleanup sqlalchemy collectd configuration

Browbeat adds configuration for sqlalchemy collectd on the configuration files of many Openstack API containers on controller hosts. This causes issues in the next overcloud deployment. There is a playbook to clean up sqlalchemy collectd configuration installed by Browbeat from Openstack API containers.

To cleanup :

::: $ cd ansible $ ansible-playbook -i hosts.yml install/cleanup_sqlalchemy_collectd.yml

Generate CSV file/Google Sheets from Rally json file --------------------------------------------Rally generates a json file with data about atomic actions duration from each iteration. These atomic actions often occur multiple times within one iteration. Browbeat has a script which allows a user to generate a CSV file and also has an option to generate a Google Sheet about individual resource duration through the Rally json file. To use the script to upload to Google Sheets, a Google Drive service account is required. The script sends an email to the email id of the user with the Google sheet if the --uploadgooglesheet option is enabled.

To generate only a CSV file and not upload to Google Sheets :

$ source .browbeat-venv/bin/activate && cd utils
$ python rally_google_sheet_gen.py -c -f <path to directory to write csv file locally>
  -j <path to rally json file>
  -a <space separated list of atomic actions(Eg.: boot_server create_network)>

To only upload to Google Sheets and not generate CSV files :

::: $ source .browbeat-venv/bin/activate && cd utils $ python rally_google_sheet_gen.py -j <path to rally json files> -a <space separated list of atomic actions(Eg.: boot_server create_network)> -g -s <path to google service account json credentials file> -e <email id of user> -n <name of google sheet to be created>

To only upload to Google Sheets along with SLA failures and not generate CSV files :

::

$ source .browbeat-venv/bin/activate && cd utils

$ python rally_google_sheet_gen.py: -j <path to rally json files> -a <space separated list of atomic actions(Eg.: boot_server create_network)> -g -v <space separated list of max durations as per SLA criteria(Eg.: 10 20 120). The ordering must match the ordering of atomic actions> -s <path to google service account json credentials file> -e <email id of user> -n <name of google sheet to be created>

To generate a CSV file and upload to Google Sheets :

::: $ source .browbeat-venv/bin/activate && cd utils $ python rally_google_sheet_gen.py -c -f <path to directory to write csv file locally> -j <path to rally json files> -a <space separated list of atomic actions(Eg.: boot_server create_network)> -g -s <path to google service account json credentials file> -e <email id of user> -n <name of google sheet to be created>
