Functions

func ConvertToZapLevel

func ConvertToZapLevel(lvl string) zapcore.Level

ConvertToZapLevel converts log level string to zapcore.Level.

func MergeOutputPaths

func MergeOutputPaths(cfg zap.Config) zap.Config

MergeOutputPaths merges logging output paths, resolving conflicts.

func NewJournalWriter

func NewJournalWriter(wr io.Writer) (io.Writer, error)

NewJournalWriter wraps "io.Writer" to redirect log output to the local systemd journal. If journald send fails, it fails back to writing to the original writer. The decode overhead is only <30µs per write. Reference: https://github.com/coreos/pkg/blob/master/capnslog/journald_formatter.go
