Functions ¶
func CgroupFsMagicStr ¶
DetectCgroupFSMagic() runs by default DetectCgroupMode() CgroupFsMagicStr() Returns "Cgroupv2" or "Cgroupv1" based on passed magic.
func DetectCgroupFSMagic ¶
DetectCgroupFSMagic() runs by default DetectCgroupMode() Return the Cgroupfs v1 or v2 that will be used by bpf programs
func DetectDeploymentMode ¶
func DiscoverSubSysIds ¶
func DiscoverSubSysIds() error
DiscoverSubSysIds() Discover Cgroup SubSys IDs and indexes. of the corresponding controllers that we are interested in. We need this dynamic behavior since these controllers are compile config.
func GetCgroupFSMagic ¶
func GetCgroupFSMagic() uint64
func GetCgrpControllerName ¶
func GetCgrpControllerName() string
GetCgrpControllerName() returns the name of the controller that is being used as fallback from the css to get cgroup information and track processes.
func GetCgrpHierarchyID ¶
func GetCgrpHierarchyID() uint32
GetCgrpHierarchyID() returns the ID of the Cgroup hierarchy that is used to track processes. This is used for Cgroupv1 as for Cgroupv2 we run in the default hierarchy.
func GetCgrpSubsystemIdx ¶
func GetCgrpSubsystemIdx() uint32
GetCgrpSubsystemIdx() returns the Index of the subsys or hierarchy to be used to track processes.
func GetDeploymentMode ¶
func GetDeploymentMode() uint32
Types ¶
type CgroupModeCode ¶
type CgroupModeCode int
const ( /* Cgroup Mode: * https://systemd.io/CGROUP_DELEGATION/ * But this should work also for non-systemd environments: where * only legacy or unified are available by default. */ CGROUP_UNDEF CgroupModeCode = iota CGROUP_LEGACY CgroupModeCode = 1 CGROUP_HYBRID CgroupModeCode = 2 CGROUP_UNIFIED CgroupModeCode = 3 )
func DetectCgroupMode ¶
func DetectCgroupMode() (CgroupModeCode, error)
DetectCgroupMode() Returns the current Cgroup mode that is applied to the system This applies to systemd and non-systemd machines, possible values:
- CGROUP_UNDEF: undefined
- CGROUP_LEGACY: Cgroupv1 legacy controllers
- CGROUP_HYBRID: Cgroupv1 and Cgroupv2 set up by systemd
- CGROUP_UNIFIED: Pure Cgroupv2 hierarchy

func GetCgroupMode ¶
func GetCgroupMode() CgroupModeCode
func (CgroupModeCode) String ¶
