Functions

func FetchAllOIDsUsingGetNext

func FetchAllOIDsUsingGetNext(session Session) []string

FetchAllOIDsUsingGetNext fetches all available OIDs Fetch all scalar OIDs and first row of table OIDs.

func FetchSysObjectID

func FetchSysObjectID(session Session) (string, error)

FetchSysObjectID fetches the sys object id from the device

func GetNextColumnOidNaive

func GetNextColumnOidNaive(oid string) (string, error)

GetNextColumnOidNaive will return the next column OID for a given OID This is a naive algorithm based on detecting `.1.` (the table Entry oid that contains), increase the next digit and returns it. Caveat: if the input OID index contain `.1.` the function won't return the next column OID but all the OID elements until `.1.`.

Types

type Factory

type Factory func(config *checkconfig.CheckConfig) (Session, error)

Factory will create a new Session

type GosnmpSession

type GosnmpSession struct {
	// contains filtered or unexported fields
