Types

type Tester

type Tester struct {
	// contains filtered or unexported fields
}

func NewTester

func NewTester(node *provider.Node, probePod *corev1.Pod, commander clientsholder.Command) (*Tester, error)

func (*Tester) HasMcSystemdHugepagesUnits

func (tester *Tester) HasMcSystemdHugepagesUnits() bool

func (*Tester) Run

func (tester *Tester) Run() error

func (*Tester) TestNodeHugepagesWithKernelArgs

func (tester *Tester) TestNodeHugepagesWithKernelArgs() (bool, error)

TestNodeHugepagesWithKernelArgs compares node hugepages against kernelArguments config. The total count of hugepages of the size defined in the kernelArguments must match the kernArgs' hugepages value. For other sizes, the sum should be 0.

func (*Tester) TestNodeHugepagesWithMcSystemd

func (tester *Tester) TestNodeHugepagesWithMcSystemd() (bool, error)

TestNodeHugepagesWithMcSystemd compares the node's hugepages values against the mc's systemd units ones.
