Types

type ClientConfig

type ClientConfig struct {
	// Timeout to wait for a response.
	Timeout config.Duration `toml:"timeout"`
	Retries int             `toml:"retries"`
	// Values: 1, 2, 3
	Version uint8 `toml:"version"`
	// Path to mib files
	Path []string `toml:"path"`

	// Parameters for Version 1 & 2
	Community string `toml:"community"`

	// Parameters for Version 2 & 3
	MaxRepetitions uint32 `toml:"max_repetitions"`

	// Parameters for Version 3
	ContextName string `toml:"context_name"`
	// Values: "noAuthNoPriv", "authNoPriv", "authPriv"
	SecLevel string `toml:"sec_level"`
	SecName  string `toml:"sec_name"`
	// Values: "MD5", "SHA", "". Default: ""

	PrivProtocol string `toml:"priv_protocol"`
	PrivPassword string `toml:"priv_password"`
	EngineID     string `toml:"-"`
	EngineBoots  uint32 `toml:"-"`
	EngineTime   uint32 `toml:"-"`
}

type GosnmpWrapper

type GosnmpWrapper struct {
	*gosnmp.GoSNMP
}

GosnmpWrapper wraps a *gosnmp.GoSNMP object so we can use it as a snmpConnection.

func NewWrapper

func NewWrapper(s ClientConfig) (GosnmpWrapper, error)

func (GosnmpWrapper) Host

func (gs GosnmpWrapper) Host() string

Host returns the value of GoSNMP.Target.

func (*GosnmpWrapper) SetAgent

func (gs *GosnmpWrapper) SetAgent(agent string) error

SetAgent takes a url (scheme://host:port) and sets the wrapped GoSNMP struct's corresponding fields. This shouldn't be called after using the wrapped GoSNMP struct, for example after connecting.

func (GosnmpWrapper) Walk

func (gs GosnmpWrapper) Walk(oid string, fn gosnmp.WalkFunc) error

Walk wraps GoSNMP.Walk() or GoSNMP.BulkWalk(), depending on whether the connection is using SNMPv1 or newer.

type MibEntry

type MibEntry struct {
	MibName string
	OidText string
}

The following is for snmp_trap

func TrapLookup

func TrapLookup(oid string) (e MibEntry, err error)
