./mysql-sniffer -h

Usage mysql-sniffer [-d] -i eth0 -p 3306,3307,3308 -l /var/log/mysql-sniffer/ -e stderr

[-d] -i eth0 -r 3000-4000

-d daemon mode.

-s how often to split the log file(minute, eg. 1440). if less than 0, split log everyday

-i interface. Default to eth0

-p port, default to 3306. Multiple ports should be splited by ','. eg. 3306,3307

this option has no effect when -f is set.

-r port range, Don't use -r and -p at the same time

-l query log DIRECTORY. Make sure that the directory is accessible. Default to stdout.

-e error log FILENAME or 'stderr'. if set to /dev/null, runtime error will not be recorded

-f filename. use pcap file instead capturing the network interface

-w white list. dont capture the port. Multiple ports should be splited by ','.

-t truncation length. truncate long query if it's longer than specified length. Less than 0 means no truncation

-n keeping tcp stream count, if not set, default is 65536. if active tcp count is larger than the specified count, mysql-sniffer will remove the oldest one
