Variables ¶
var BenignDropReasons = map[string]bool{ "NOT_SPECIFIED": true, "NO_SOCKET": true, "SOCKET_FILTER": true, "OTHERHOST": true, "TCP_FLAGS": true, "TCP_ZEROWINDOW": true, "TCP_OLD_DATA": true, "TCP_OLD_SEQUENCE": true, "TCP_OVERWINDOW": true, "TCP_OFOMERGE": true, "SKB_CONSUMED": true, "TCP_OFO_QUEUE_PRUNE": true, }
BenignDropReasons is the canonical set of kernel SKB_DROP_REASON strings that represent normal TCP/IP lifecycle events, not actual packet loss. Maintained in one place to prevent divergence across packages.
Functions ¶
func FieldsAt ¶
FieldsAt returns the field at the given index from a whitespace-split line. Returns empty string if index is out of bounds.
func IsBenignDropReason ¶
IsBenignDropReason returns true if the drop reason string is benign.
func ParseFloat64 ¶
ParseFloat64 parses a string to float64, returning 0 on error. NaN and Inf inputs are also treated as 0 to prevent downstream poisoning.
func ParseKeyValueFile ¶
ParseKeyValueFile parses a file with "key value" or "key: value" lines.
func ParseKeyValueLines ¶
ParseKeyValueLines parses lines with "key value" or "key: value" format.
func ParseUint64 ¶
ParseUint64 parses a string to uint64, returning 0 on error.
func RatePct ¶
RatePct computes the percentage utilization between two counter values given a time delta and a total capacity in the same unit.
func ReadFileLines ¶
ReadFileLines reads a file and returns its lines.
func ReadFileString ¶
ReadFileString reads a file and returns its contents as a string.
