Neutron ML2/ODL Performance testing
|
||||
===================================
|
||||
|
||||
:status: **draft**
|
||||
:version: 1.0
|
||||
|
||||
:Abstract:
|
||||
|
||||
This document describes how control plane and network data plane performance
|
||||
testing is conducted on an OpenStack Cloud using the Neutron ML2/ODL plugin.
|
||||
The control plane performance is going to be analyzed in terms of response time
|
||||
and the parameters used to characterize the data plane performance are throughput
|
||||
in Mbps and latency in milliseconds and number of Request-Response Transactions.
|
||||
|
||||
|
||||
|
||||
Test Plan
|
||||
=========
|
||||
|
||||
Characterize the resource consumption, control plane response time and
|
||||
network performance of an OpenStack Cloud using the Neutron ML2/ODL Plugin.
|
||||
Control plane response time is measured when creating and listing common Neutron
|
||||
resources as well as during actions that require interaction between Neutron and
|
||||
other OpenStack services such as Nova. Network plane performance is measured for
|
||||
both TCP and UDP protocols, with throughput, latency and Request-Response
|
||||
benchmarks for TCP and Packets Per Second (PPS) and loss for UDP.
|
||||

||||

||||

System Performance Monitoring
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
Record System performance metrics into a separate metrics
|
||||
collection/storage/analysis system. Suggested system would be a separate
|
||||
machine with Carbon, Graphite, and Grafana with dashboards for monitoring
|
||||
system resource utilization. To push metrics into the TSDB, collectd
|
||||
can/should be installed on all monitored machines. (Deployment, Controllers,
|
||||
and Computes)
|
||||
|
||||

^^^^^^^^^^^
|
||||
Create and list servers on a subnet and compare time taken for server
|
||||

|
||||
ML2/ODL have both take different approaches when notifying NOVA that
|
||||
the network is ready.

Tools
|
||||
-----
|
||||
Browbeat_ is used to orchestrate several Rally_ and Shaker_ scenarios and
|
||||
results are pushed to Elasticsearch for easy visualization through Kibana.
|
||||
|
||||
Setup
|
||||
^^^^^^^^
|
||||
|
||||
#. Deploy OpenStack Cloud using TripleO
|
||||
#. Install testing and monitoring tooling
|
||||
#. Gather metadata on Cloud
|
||||
#. Run tests
|
||||
|
||||
Analysis
|
||||
^^^^^^^^
|
||||
|
||||
Review System performance metrics graphs during test duration to observe for
|
||||
stopping/failure conditions. Review testing harness output for test failure
|
||||
conditions. API response time and several statistics associated with it such as
|
||||
percentiles can be obtained from Rally and Shaker output. Compare ML2/OVS with
|
||||
ML2/ODL.
