Functions ¶
func AddLogConsFlags ¶
func AddLogConsFlags()
func AddLogFileFlags ¶
func AddLogFileFlags()
func CtxWith ¶ added in v0.4.0
CtxWith returns a new context, based on ctx, that embeds argument logger. The logger can be recovered using GetLogger. Attaching a logger to a context which already contains one will overwrite the existing value.
func FilterTraceHandler ¶ added in v0.4.0
func LogPanicAndExit ¶
func LogPanicAndExit()
func SetupFromFlags ¶
func SetupLogConsole ¶
SetupLogConsole sets up logging on default stderr. logLevel can be one of trace, debug, info, warn, error, and crit, and states the minimum level of logging events that gets printed to the console.
func SetupLogFile ¶
func SetupLogFile(name string, logDir string, logLevel string, logSize int, logAge int, logBackups int, logFlush int) error
SetupLogFile initializes a file for logging. The path is logDir/name.log if name doesn't already contain the .log extension, or logDir/name otherwise. logLevel can be one of trace, debug, info, warn, error, and crit and states the minimum level of logging events that get written to the file. logSize is the maximum size, in MiB, until the log rotates. logAge is the maximum number of days to retain old log files. logBackups is the maximum number of old log files to retain. If logFlush > 0, logging output is buffered, and flushed every logFlush seconds. If logFlush < 0: logging output is buffered, but must be manually flushed by calling Flush(). If logFlush = 0 logging output is unbuffered and Flush() is a no-op.
