const DefaultBulkMaxRepetitions = uint32(10)

DefaultBulkMaxRepetitions is the default max rep Using too high max repetitions might lead to tooBig SNMP error messages. - Java SNMP and gosnmp (gosnmp.defaultMaxRepetitions) uses 50 - snmp-net uses 10

View Source 
const DefaultPingCount int = 2

DefaultPingCount is the default number of pings to send per check run

View Source 
const DefaultPingInterval = 10 * time.Millisecond

DefaultPingInterval is the default time to wait between sending ping packets

View Source 
const DefaultPingTimeout = 3 * time.Second

DefaultPingTimeout is the default timeout for all pings to return in a check run

LegacyMetadataConfig contains metadata config used for backward compatibility When users have their own copy of _base.yaml and _generic_if.yaml files they won't have the new profile based metadata definitions for device and interface resources The LegacyMetadataConfig is used as fallback to provide metadata definitions for those resources.
