|test case id | OPNFV_YARDSTICK_TC061_Network Utilization |
| | |
+--------------+--------------------------------------------------------------+
|metric | Network utilization |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | To evaluate the IaaS network capability with regards to |
| | network utilization, including Total number of packets |
| | received per second, Total number of packets transmitted per |
| | second, Total number of kilobytes received per second, Total |
| | number of kilobytes transmitted per second, Number of |
| | compressed packets received per second (for cslip etc.), |
| | Number of compressed packets transmitted per second, Number |
| | of multicast packets received per second, Utilization |
| | percentage of the network interface. |
| | This test case should be run in parallel to other Yardstick |
| | test cases and not run as a stand-alone test case. |
| | Measure the network usage statistics from the network devices|
| | 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: netutilization.yaml (in the 'samples' directory) |
| | |
| | * interval: 1 - repeat, pausing every 1 seconds in-between. |
| | * count: 1 - display statistics 1 times, then exit. |
| | |
+--------------+--------------------------------------------------------------+
|test tool | sar |
| | |
| | The sar command writes to standard output the contents of |
| | selected cumulative activity counters in the operating |
| | system. |
| | sar 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 sar 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 sar logs are produced and stored. |
| | |
| | Result: logs are stored. |
| | |
+--------------+--------------------------------------------------------------+
|test verdict | None. Network utilization results are fetched and stored. |
