Functions

func ConcatFormat

func ConcatFormat(stringList []string) string

func FormatUUID

func FormatUUID(uuid *events.UUID) string

func GetHostIPInfo

func GetHostIPInfo(host string) (string, string, error)

GetHostIPInfo returns hostname and corresponding IP address If empty host is passed in, the current hostname and IP of the host will be returned. If the IP of the hostname can't be resolved, an empty IP and an error will be returned

func NanoSecondsToSeconds

func NanoSecondsToSeconds(nanoseconds int64) string

func ToJson

func ToJson(msg string) interface{}

ToJSON tries to detect the JSON pattern for msg first, if msg contains JSON pattern either a map or an array (for efficiency), it will try to convert msg to a JSON object. If the convertion success, a JSON object will be returned. Otherwise the original msg will be returned If the msg param doesn't contain the JSON pattern, the msg will be returned directly
