Types ¶
type ConnectionStat ¶
type ConnectionStat struct { Fd uint32 `json:"fd"` Family uint32 `json:"family"` Type uint32 `json:"type"` Laddr Addr `json:"localaddr"` Raddr Addr `json:"remoteaddr"` Status string `json:"status"` Uids []int32 `json:"uids"` Pid int32 `json:"pid"` }
func Connections ¶
func Connections(kind string) ([]ConnectionStat, error)
func ConnectionsMax ¶
func ConnectionsMax(kind string, max int) ([]ConnectionStat, error)
func ConnectionsPidMaxWithoutUids ¶
func ConnectionsPidMaxWithoutUids(kind string, pid int32, max int) ([]ConnectionStat, error)
func ConnectionsPidWithoutUids ¶
func ConnectionsPidWithoutUids(kind string, pid int32) ([]ConnectionStat, error)
func ConnectionsWithContext ¶
func ConnectionsWithContext(ctx context.Context, kind string) ([]ConnectionStat, error)
func ConnectionsWithoutUids ¶
func ConnectionsWithoutUids(kind string) ([]ConnectionStat, error)
Return a list of network connections opened, omitting `Uids`. WithoutUids functions are reliant on implementation details. They may be altered to be an alias for Connections or be removed from the API in the future.
func ConnectionsWithoutUidsWithContext ¶
func ConnectionsWithoutUidsWithContext(ctx context.Context, kind string) ([]ConnectionStat, error)
func (ConnectionStat) String ¶
func (n ConnectionStat) String() string
type ConntrackStat ¶
