This adds SLA plugin that finds minimum and maximum duration of
iterations completed without errors during Rally task execution.
Assuming that minimum duration is 100%, it calculates
performance degradation against maximum duration.
Example config:
sla:
performance_degradation:
max_degradation: 75
Spec: sla_pd_plugin

SLA Performance degradation plugin

Problem description
|
|
===================
|
|
|
|
During density and reliability testing of OpenStack with Rally
|
|
we observed test cases, during execution of which performance
|
|
of OpenStack cluster has been drammatically degradated.
|
|
|
|
Proposed change
|
|
===============
|
|
|
|
Develop a new Rally SLA plugin: *performance_degradation*
|
|
|
|
This SLA plugin should find minimum and maximum duration of
|
|
iterations completed without errors during Rally task execution.
|
|
Assuming that minimum duration is 100%, it should calculate
|
|
performance degradation against maximum duration.
|
|
|
|
SLA plugin results:
|
|
- failure if performance degradation is more than value set
|
|
in plugin's max_degradation parameter;
|
|
- success if degradation is less
|
|
- performance degradation value as a percentage.
|
|
|
|
How to enable this plugin:
|
|
|
|
.. code:: json
|
|
|
|
"sla": {
|
|
"performance_degradation": {
|
|
"max_degradation": 50
|
|
}
|
|
}
