Functions ¶
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)
Return a list of network connections opened.
func ConnectionsMax ¶
func ConnectionsMax(kind string, max int) ([]ConnectionStat, error)
Return a list of network connections opened returning at most `max` connections for each running process.
func ConnectionsPid ¶
func ConnectionsPid(kind string, pid int32) ([]ConnectionStat, error)
Return a list of network connections opened by a process.
func ConnectionsPidMax ¶
func ConnectionsPidMax(kind string, pid int32, max int) ([]ConnectionStat, error)
Return up to `max` network connections opened by a process.
func (ConnectionStat) String ¶
func (n ConnectionStat) String() string
type FilterStat ¶
type FilterStat struct {
ConnTrackCount int64 `json:"conntrackCount"`
ConnTrackMax int64 `json:"conntrackMax"`
}
func FilterCounters ¶
func FilterCounters() ([]FilterStat, error)
NetFilterCounters returns iptables conntrack statistics the currently in use conntrack count and the max. If the file does not exist or is invalid it will return nil.
type IOCountersStat ¶
type IOCountersStat struct {
Name string `json:"name"` // interface name
BytesSent uint64 `json:"bytesSent"` // number of bytes sent
BytesRecv uint64 `json:"bytesRecv"` // number of bytes received
PacketsSent uint64 `json:"packetsSent"` // number of packets sent
PacketsRecv uint64 `json:"packetsRecv"` // number of packets received
Errin uint64 `json:"errin"` // total number of errors while receiving
Errout uint64 `json:"errout"` // total number of errors while sending
Dropin uint64 `json:"dropin"` // total number of incoming packets which were dropped
Dropout uint64 `json:"dropout"` // total number of outgoing packets which were dropped (always 0 on OSX and BSD)
Fifoin uint64 `json:"fifoin"` // total number of FIFO buffers errors while receiving
Fifoout uint64 `json:"fifoout"` // total number of FIFO buffers errors while sending
}
func IOCounters ¶
func IOCounters(pernic bool) ([]IOCountersStat, error)
NetIOCounters returnes network I/O statistics for every network interface installed on the system. If pernic argument is false, return only sum of all information (which name is 'all'). If true, every network interface installed on the system is returned separately.
func IOCountersByFile ¶
func IOCountersByFile(pernic bool, filename string) ([]IOCountersStat, error)
func (IOCountersStat) String ¶
func (n IOCountersStat) String() string
type InterfaceAddr ¶
type InterfaceAddr struct {
Addr string `json:"addr"`
}
NetInterfaceAddr is designed for represent interface addresses
func (InterfaceAddr) String ¶
func (n InterfaceAddr) String() string
type InterfaceStat ¶
type InterfaceStat struct {
MTU int `json:"mtu"` // maximum transmission unit
Name string `json:"name"` // e.g., "en0", "lo0", "eth0.100"
HardwareAddr string `json:"hardwareaddr"` // IEEE MAC-48, EUI-48 and EUI-64 form
Flags []string `json:"flags"` // e.g., FlagUp, FlagLoopback, FlagMulticast
Addrs []InterfaceAddr `json:"addrs"`
}
func Interfaces ¶
func Interfaces() ([]InterfaceStat, error)
func (InterfaceStat) String ¶
func (n InterfaceStat) String() string
type ProtoCountersStat ¶
type ProtoCountersStat struct {
Protocol string `json:"protocol"`
Stats map[string]int64 `json:"stats"`
}
System wide stats about different network protocols
func ProtoCounters ¶
func ProtoCounters(protocols []string) ([]ProtoCountersStat, error)
NetProtoCounters returns network statistics for the entire system If protocols is empty then all protocols are returned, otherwise just the protocols in the list are returned. Available protocols:
ip,icmp,icmpmsg,tcp,udp,udplite
func (ProtoCountersStat) String ¶
func (n ProtoCountersStat) String() string
