|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.      |
