hugepages plugin tests:
Test Environment details:
- Bare Metal, Ubuntu 16.04.1 LTS
- Kernel version: 4.4.0-43-generic
Repo/branch used:
- collectd/master
Tests precondition:
Hugepages plugin configuration:
- Open collectd config file: vim /install_folder/etc/collectd.conf
- Uncomment LoadPlugin "hugepages" fields.
- Add global to collectd.conf: Interval 2
NOTE:
The following set of tests is parametrized and run for 1G and 2M hugepage sizes. So, it means that number of executed tests is multiplied by 2 - 1(last test case #12 is run once because it covers mixed of 1G and 2M sizes).
# | Test summary | Steps | Actual result | Expected result | Status - PASS/FAIL | Automated status |
