As an example see the | -| | /yardstick/tools/ directory for how to generate a Linux | -| | image with cachestat included.) | -| | | -+--------------+--------------------------------------------------------------+ -|test | cachestat test is invoked in a host VM on a compute blade, | -|description | cachestat test requires some other test cases running in the | -| | host to stimulate workload. | -| | | -+--------------+--------------------------------------------------------------+ -|configuration | File: cachestat.yaml (in the 'samples' directory) | -| | | -| | Interval is set 1.
