Features `KloudBuster Documentation <http://kloudbuster.readthedocs.org>`_
--------
* Neutron configuration agnostic (any encapsulation, any overlay, any plugin)
* OpenStack Storage backend agnostic
* User can specify any number of tenants, routers, networks, VM instances (only
limited by cloud capacity) and KloudBuster will stage all these resources in a
way that makes sense for operational usage
* Real VM-level performance and scale numbers (not bare metal)
* Punishing scale (thousands of VMs and enough load to fill even the fastest NIC
cards or load any storage cluster with ease - if your cloud can even support
that much)
* Data plane with HTTP traffic load:
* Can load the data plane with one OpenStack cloud (single-cloud operations
for L3 East-West scale) or 2 OpenStack clouds (dual-cloud operations with
one cloud hosting the HTTP servers and the other loading HTTP traffic for
L3 North-South scale testing)
* Real HTTP servers (Nginx) running in real Linux images (Ubuntu 14.04)
* Can specify any number of HTTP servers per tenant (as many as your cloud
can handle)
* High performance and highly scalable HTTP traffic generators to simulate
huge number of HTTP users and TCP connections (hundreds of thousands to
millions of concurrent and active connections)
* Overall throughput aggegation and loss-less latency aggregation for every
single HTTP request (typically millions per run) using the open source
HdrHistogram library
* Traffic shaping to specify on which links traffic should flow
* Can support periodic reporting and aggregation of results
* Storage load:
* VM-level Cinder volume (block storage) or Ephemeral disk file I/O performance measurement
using FIO running inside VMs (not bare metal)
* Supports random and sequential file access mode
* Supports read, write and read/write mix
* IOPs, bandwitdh and loss-less latency aggregation
* User configurable storage workload profiles
* Supports automated scale progressions (VM count series in any multiple
increment) to reduce dramatically scale testing time
* Highly efficient and scalable metric aggregation
* Automatic cleanup upon termination (can be disabled)
* Manual cleanup script
* KloudBuster Server to drive scale test:
* from any browser (KloudBuster Web UI)
* from any external programs (KloudBuster REST API)
* Aggregated results provide an easy to understand way to assess the scale of
the cloud under test
* KloudBuster VM image pre-built and available from the OpenStack Community App
Catalog (https://apps.openstack.org/)
Limitations and Non-Goals
-------------------------
* Requires Neutron networking (does not support Nova networking)
* Only supports HTTP and storage traffic in this version
Unlike some other scaling test frameworks, KloudBuster does *not* attempt to:
* provide a scale test framework that works across different cloud technologies
(OpenStack + AWS + Google Cloud + ...) - we are only focusing on OpenStack
* provide a scale test framework that is flexible and programmable to do everything -
we just focus on opinionated and well targeted performance and scale areas
with sensible use cases and available in a fully integrated and easy to consume
packaged format
* replace bare metal and domain specific native performance and scale frameworks
(line level traffic generators, ceph specific performance and scale tools...)

This page has links to examples of scale test reports in HTML format generated by KloudBuster.
These reports were generated within minutes after starting the scale test from a
bare bone OpenStack cloud (not running anything).
Click on the thumbnail images to view the result HTML file in your browser (you will need
access to the Internet to view these files as they reference multiple Java script libraries in CDN).
Sample HTTP Scale Report
------------------------
The following report shows an HTTP scale run with results for 1 to 20 HTTP servers
(running in as many server VMs) in increment of 5, where each HTTP server is receiving
HTTP requests from 1 HTTP traffic generator that runs in a separate VM and emulates 1,000
users sending 1 request per second each (for a total of 1000 requests per second per HTTP server).
The topology used for the test is 1 tenant, 1 router, 4 networks and 5 HTTP servers per network.
Each iteration is programmed to run for 30 seconds.
This scale settings can be viewed in the Configuration tab.
The table shows the results for each iteration step, with the requested and measured RPS
(HTTP requests per second) and the corresponding aggregated download throughput (the sum of all
downloads for all clients).
The latency distribution is shows in the chart, where each line corresponds to one load level (or
iteration in the progression). Lines can be individually shown/hidden by clicking on the
corresponding legend item.
For example, the largest scale involves 20,000 simultaneous users sending an aggregate of 18,621
HTTP requests per second and the latency chart tells us that 99.9% of these 18,621 requests are
replied within 34ms, which is actually excellent.
Note that this test is configured to reuse HTTP connections meaning that we do not have the
overhead of creating a new TCP connection for every HTTP request. This also means that this cloud
had 20,000 TCP active connections at all times during the scale test.

Sample Storage Scale Report
---------------------------
This is a report for a storage scale test using the default workload suite with a progression run
from 1 VM to 20 VMs in increment of 5, and 30 second run per iteration.
This results in 6 tabs of results (1 per workload). The mixed read/write tabs further split in
2 sub tabs (1 for read and 1 for write results).
The random read tab shows that each VM could achieve its requested 100 IOPs across the progression.
The lines represent the latency value at given percentile and can be individually shown/hidden by clicking
the corresponding legend item.
As an example, 20 VMs represents a combined 2,000 IOPs measured for a total of 60,000 random read operations.
The latency line tells us that 99.9% of these 60,000 read operations are completed within 1.576 msec.
.. image:: images/kb-storage-thumbnail.png
:target: https://htmlpreview.github.io/?https://github.com/openstack/kloudbuster/blob/master/doc/source/gallery/storage.html
The sequential write results are more challenging as they show that the VMs cannot achieve their requested
write bandwidth (60MB/s) and can only get 49MB/s each when there are 20 of such VMs.
The latency lines also reflect that stress by peaking at 500 ms for 99.99% of all write operations (although
latency is not nearly as critical for sequential access than for random access).

KloudBuster version 6
=====================
How good is your OpenStack *data plane* or *storage service* under real heavy load?
KloudBuster is a tool that can load the data plane or storage infrastructure of any OpenStack
cloud at massive scale and measure how well the cloud behaves under load
where it matters: from the VMs standpoint, where cloud applications run.
Accessible to anybody with basic knowledge of OpenStack, installs in minutes and runs
off the box with sensible default workloads in a fully automated way.
CLI/REST or Web User Interface.. you pick what works best for you.
Feature List
------------
* Neutron configuration agnostic (any encapsulation, any overlay, any plugin)
* OpenStack Storage backend agnostic
* Real VM-level performance and scale numbers (not bare metal)
* Punishing scale (thousands of VMs and enough load to fill even the fastest NIC
cards or load any storage cluster with ease)
* Data plane with HTTP traffic load:
* Can load the data plane with one OpenStack cloud (single-cloud operations
for L3 East-West scale) or 2 OpenStack clouds (dual-cloud operations with
one cloud hosting the HTTP servers and the other loading HTTP traffic for
L3 North-South scale testing)
* Real HTTP servers (Nginx) running in real Linux images (Ubuntu 14.04)
* Can specify any number of tenants, routers and networks
* Can specify any number of HTTP servers per tenant (as many as your cloud
can handle)
* High performance and highly scalable HTTP traffic generators to simulate
huge number of HTTP users and TCP connections (hundreds of thousands to
millions of concurrent and active connections)
* Overall throughput aggegation and loss-less millisecond-precision latency
aggregation for every single HTTP request (typically millions per run)
* Traffic shaping to specify on which links traffic should flow
* Can support periodic reporting and aggregation of results
* Storage load:
* VM-level Cinder volume (block storage) or Ephemeral disk file I/O performance measurement
using FIO running inside VMs (not bare metal)
* Supports random and sequential file access mode
* Supports any mix of read/write
* IOPs, bandwitdh and loss-less millisecond-precision latency aggregation for every
IO operation (typically millions per run)
* User configurable workload sequence
* Supports automated scale progressions (VM count series in any multiple
increment) to reduce dramatically scale testing time
* Highly efficient and scalable metric aggregation
* Automatic cleanup upon termination
* Regular expression based cleanup script (`cleanup`_)
* KloudBuster server mode to drive scale test:
* from any browser (KloudBuster Web UI)
* or from any external programs (KloudBuster REST API)
* Aggregated results provide an easy to understand way to assess the scale of
the cloud under test
* KloudBuster VM image pre-built and available from the OpenStack Community App
Catalog (https://apps.openstack.org/)
*Diagrams* describing how the scale test resources are staged and how the traffic flows are available
in :ref:`arch`.
Scale results are available in json form or in html form with javascript graphical charts generated straight off the tool.
*Examples of results* are available in :ref:`gallery`.
Limitations and Non-Goals
-------------------------
* Requires Neutron networking (does not support Nova networking)
* Only supports HTTP and storage traffic in this version
Unlike some other scaling test frameworks, KloudBuster does *not* attempt to:
* provide a scale test framework that works across different cloud technologies
(OpenStack + AWS + Google Cloud + ...) - we are only focusing on OpenStack
* provide a scale test framework that is flexible and programmable to do everything -
we just focus on opinionated and well targeted performance and scale areas
with sensible use cases and available in a fully integrated and easy to consume
packaged format
* replace bare metal and domain specific native performance and scale frameworks
(line level traffic generators, ceph specific performance and scale tools...)
Contributions and Feedbacks
---------------------------
If you are interested in OpenStack Performance and Scale, contributions and
feedbacks are welcome!
If you have any feedbacks or would like to make small or large contributions,
simply send an email to openstack-dev@lists.openstack.org with a '[kloudbuster]'
