Functions

func ActivityDumpRemoteStorageEndpoints 

func ActivityDumpRemoteStorageEndpoints(endpointPrefix string, intakeTrackType logsconfig.IntakeTrackType, intakeProtocol logsconfig.IntakeProtocol, intakeOrigin logsconfig.IntakeOrigin) (*logsconfig.Endpoints, error)

ActivityDumpRemoteStorageEndpoints returns the list of activity dump remote storage endpoints parsed from the agent config

func GetFamilyAddress 

func GetFamilyAddress(path string) (string, string)

GetFamilyAddress returns the address famility to use for system-probe <-> security-agent communication

func IsEBPFLessModeEnabled 

func IsEBPFLessModeEnabled() bool

IsEBPFLessModeEnabled returns true if the ebpfless mode is enabled it's based on the configuration itself, but will default on true if running on fargate

func ParseEvalEventType 

func ParseEvalEventType(eventType eval.EventType) model.EventType

ParseEvalEventType convert a eval.EventType (string) to its uint64 representation the current algorithm is not efficient but allows us to reduce the number of conversion functions
