Types

type GetContainerSubtreeError added in v0.3.3 

type GetContainerSubtreeError struct {
	Err error
}

func (*GetContainerSubtreeError) Error added in v0.3.3 

func (e *GetContainerSubtreeError) Error() string

func (*GetContainerSubtreeError) Unwrap added in v0.3.3 

func (e *GetContainerSubtreeError) Unwrap() error

type ProcessTreeManager 

type ProcessTreeManager interface {
	Start()
	Stop()
	GetContainerProcessTree(containerID string, pid uint32, useCache bool) (armotypes.Process, error)
	ReportEvent(eventType utils.EventType, event utils.K8sEvent) error
	GetPidList() []uint32
	// GetProcessBootTimeNs returns the process's creation time as nanoseconds
	// since boot (CLOCK_BOOTTIME), sourced exclusively from /proc/<pid>/stat
	// field 22 — either the periodic scan or the on-demand read performed when a
	// fork/exec creates the node. Returns 0 when unknown: the process died
	// before its creation event was processed, or it has already exited.
	//
	// This is the sole process-identity time source. The wall-clock
	// armotypes.Process.StartTime carried on tree nodes is display-only and
	// inherits btime's whole-second skew, so it must never be compared for
	// identity.
	GetProcessBootTimeNs(pid uint32) uint64
}

func NewProcessTreeManager 

func NewProcessTreeManager(
	creator processtreecreator.ProcessTreeCreator,
	containerTree containerprocesstree.ContainerProcessTree,
	config config.Config,
) ProcessTreeManager

NewProcessTreeManager creates a new process tree manager

type ProcessTreeManagerImpl 

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

ProcessTreeManagerImpl implements the ProcessTreeManager interface

func (*ProcessTreeManagerImpl) GetContainerProcessTree 

func (ptm *ProcessTreeManagerImpl) GetContainerProcessTree(containerID string, pid uint32, useCache bool) (armotypes.Process, error)

func (*ProcessTreeManagerImpl) GetPidList added in v0.2.384 

func (ptm *ProcessTreeManagerImpl) GetPidList() []uint32

func (*ProcessTreeManagerImpl) GetProcessBootTimeNs added in v0.3.167 

func (ptm *ProcessTreeManagerImpl) GetProcessBootTimeNs(pid uint32) uint64

func (*ProcessTreeManagerImpl) ReportEvent 

func (ptm *ProcessTreeManagerImpl) ReportEvent(eventType utils.EventType, event utils.K8sEvent) error

func (*ProcessTreeManagerImpl) Start 

func (ptm *ProcessTreeManagerImpl) Start()

Start initializes the process tree manager and starts background tasks

func (*ProcessTreeManagerImpl) Stop 

func (ptm *ProcessTreeManagerImpl) Stop()

Stop shuts down the process tree manager and stops background tasks

type ProcessTreeManagerMock added in v0.2.384 

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

ProcessTreeManagerMock implements the ProcessTreeManager interface for testing

func NewProcessTreeManagerMock added in v0.2.384 

func NewProcessTreeManagerMock() *ProcessTreeManagerMock

NewProcessTreeManagerMock creates a new mock process tree manager

func (*ProcessTreeManagerMock) GetContainerProcessTree added in v0.2.384 

func (m *ProcessTreeManagerMock) GetContainerProcessTree(containerID string, pid uint32, useCache bool) (armotypes.Process, error)

GetContainerProcessTree returns an empty process for testing

func (*ProcessTreeManagerMock) GetPidList added in v0.2.384 

func (m *ProcessTreeManagerMock) GetPidList() []uint32

GetPidList returns the mock PID list

func (*ProcessTreeManagerMock) GetProcessBootTimeNs added in v0.3.167 

func (m *ProcessTreeManagerMock) GetProcessBootTimeNs(pid uint32) uint64

GetProcessBootTimeNs returns the configured start time for a pid, or 0 for an unknown one — matching the real manager's "0 means unknown" contract.

func (*ProcessTreeManagerMock) ReportEvent added in v0.2.384 

func (m *ProcessTreeManagerMock) ReportEvent(eventType utils.EventType, event utils.K8sEvent) error

ReportEvent is a no-op for testing

func (*ProcessTreeManagerMock) SetPidList added in v0.2.384 

func (m *ProcessTreeManagerMock) SetPidList(pids []uint32)

SetPidList sets the list of PIDs that the mock will return

func (*ProcessTreeManagerMock) SetProcessBootTimeNs added in v0.3.167 

func (m *ProcessTreeManagerMock) SetProcessBootTimeNs(pid uint32, ns uint64)

SetProcessBootTimeNs sets the boot-relative start time the mock reports for a pid.

func (*ProcessTreeManagerMock) Start added in v0.2.384 

func (m *ProcessTreeManagerMock) Start()

Start is a no-op for testing

func (*ProcessTreeManagerMock) Stop added in v0.2.384 

func (m *ProcessTreeManagerMock) Stop()

Stop is a no-op for testing
