Raw Blame History

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:

"sla": {
    "performance_degradation": {
        "max_degradation": 50
        }
}
