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

 5          -s how often to split the log file(minute, eg. 1440). if less than 0, split log everyday
 6          -i interface. Default to eth0 #網絡卡名
 
 7          -p port, default to 3306. Multiple ports should be splited by ','. eg. 3306,3307
 8             this option has no effect when -f is set. #埠，多個埠,分割，不能和-f一起使用
 9          -r port range, Don't use -r and -p at the same time  #埠範圍，不能和-p一起使用
10          -l query log DIRECTORY. Make sure that the directory is accessible. Default to stdout. #輸出列印到檔案
 
11          -e error log FILENAME or 'stderr'. if set to /dev/null, runtime error will not be recorded
12          -f filename. use pcap file instead capturing the network interface
13          -w white list. dont capture the port. Multiple ports should be splited by ','.#排除的埠
14          -t truncation length. truncate long
 
 query if it's longer than specified length. Less than 0 means no truncation #擷取制定長度的SQL
15          -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 #指定資料包個數
