func ExpLogs ¶

func ExpLogs()

func ExpVars ¶

• epoch: start time of the current instance
• pid: process ID of current instance
• debugging: debug targets
• logging: logging configuration and runtime stats

This function should be called at program start-up.

func FlushLogs ¶

func RunDebugServer ¶

func RunDebugServer(host, port string) error

func SetDebugging ¶

func SetDebugging(onoff bool)

SetDebugging turn debugging on or off.

func SetLogBuffer ¶

func SetLogBuffer(size int) error

SetLogBuffer sets the size of log buffer. If logging is so frequent as to fill the buffer before flushing happens every 1 or 2 seconds, new messages will be dropped. Dropping of log messages can be monitored by /debug/vars if exposed.

func SetLogFile ¶

func SetLogRotate ¶

func SetLogRotate(size, keep int) error

SetLogRotate sets size of single log file, and the number of log files to keep.

func StartDebugServer ¶

func StartDebugServer(host, port string)

StartDebugServer calls RunDebugServer from a goroutine.
