Yardstick Test Case Description TC044ΒΆ

Memory Utilization
test case id OPNFV_YARDSTICK_TC044_Memory Utilization
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 conditions

The test case image needs to be installed into Glance 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.
