| | |
+--------------+--------------------------------------------------------------+
|metric | CPU load |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | To evaluate the CPU load performance of the IaaS. This test |
| | case should be run in parallel to other Yardstick test cases |
| | and not run as a stand-alone test case. |
| | Average, minimum and maximun values are obtained. |
| | The purpose is also to be able to spot trends. |
| | Test results, graphs and similar shall be stored for |
| | comparison reasons and product evolution understanding |
| | between different OPNFV versions and/or configurations. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | file: cpuload.yaml (in the 'samples' directory) |
| | |
| | * interval: 1 - repeat, pausing every 1 seconds in-between. |
| | * count: 10 - display statistics 10 times, then exit. |
| | |
+--------------+--------------------------------------------------------------+
|test tool | mpstat |
| | |
| | (mpstat is not always part of a Linux distribution, hence it |
| | needs to be installed. It is part of the Yardstick Glance |
| | image. However, if mpstat is not present the TC instead uses |
| | /proc/stats as source to produce "mpstat" output. |
| | |
+--------------+--------------------------------------------------------------+
|references | man-pages_ |
| | |
+--------------+--------------------------------------------------------------+
|applicability | Test can be configured with different: |
| | |
| | * interval; |
| | * count; |
| | * runner Iteration and intervals. |
| | |
| | There are default values for each above-mentioned option. |
| | Run in background with other test cases. |
| | |
+--------------+--------------------------------------------------------------+
|pre-test | The test case image needs to be installed into Glance |
|conditions | with mpstat included in it. |
| | |
| | No POD specific requirements have been identified. |
| | |
+--------------+--------------------------------------------------------------+
|test sequence | description and expected result |
| | |
+--------------+--------------------------------------------------------------+
|step 1 | The host is installed. The related TC, or TCs, is |
| | invoked and mpstat logs are produced and stored. |
| | |
| | Result: Stored logs |
| | |
+--------------+--------------------------------------------------------------+
|test verdict | None. CPU load results are fetched and stored. |
| | |
+--------------+--------------------------------------------------------------+
