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).
