+--------------+--------------------------------------------------------------+
|metric | Memory utilization |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | To evaluate the IaaS compute capability with regards to |
| | memory utilization.This test case should be run in parallel |
| | to other Yardstick test cases and not run as a stand-alone |
| | test case. |
| | Measure the memory usage statistics including used memory, |
| | free memory, buffer, cache and shared memory. |
| | Both average 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: memload.yaml (in the 'samples' directory) |
| | |
| | * interval: 1 - repeat, pausing every 1 seconds in-between. |
| | * count: 10 - display statistics 10 times, then exit. |
| | |
+--------------+--------------------------------------------------------------+
|test tool | free |
| | |
| | free provides information about unused and used memory and |
| | swap space on any computer running Linux or another Unix-like|
| | operating system. |
| | free is normally part of a Linux distribution, hence it |
| | doesn't needs to be installed. |
| | |

|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 free included in the image. |
| | |
| | No POD specific requirements have been identified. |
| | |
+--------------+--------------------------------------------------------------+
|test sequence | description and expected result |
| | |
+--------------+--------------------------------------------------------------+
|step 1 | The host is installed as client. The related TC, or TCs, is |
| | invoked and free logs are produced and stored. |
| | |
| | Result: logs are stored. |
| | |
+--------------+--------------------------------------------------------------+
|test verdict | None. Memory utilization results are fetched and stored. |
