Ok，可以查看 pt-query-digest工具的功能介绍了：
[root@472322 percona-toolkit-2.2.5]# pt-query-digest --help
pt-query-digest analyzes MySQL queries from slow, general, and binary log files.
It can also analyze queries from C and MySQL protocol data
from tcpdump. By default, queries are grouped by fingerprint and reported in
descending order of query time (i.e. the slowest queries first). If no C
are given, the tool reads C. The optional C is used for certain
options like L<"--since"> and L<"--until">. For more details, please use the
--help option, or try 'perldoc /usr/local/bin/pt-query-digest' for complete
documentation.
Usage: pt-query-digest [OPTIONS] [FILES] [DSN]
Options:
--ask-pass Prompt for a password when connecting to MySQL
--attribute-aliases=a List of attribute|alias,etc (default db|Schema)
--attribute-value-limit=i A sanity limit for attribute values (default
4294967296)
