pt-query-digest安装与使用

官方：https://www.percona.com/doc/percona-toolkit/2.2/pt-query-digest.html

pt-query-digest --help

# pt-query-digest --help
pt-query-digest analyzes MySQL queries from slow, general, and binary log files.
It can also analyze queries from C<SHOW PROCESSLIST> 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<FILES>
are given, the tool reads C<STDIN>.  The optional C<DSN> is used for certain
options like L<"--since"> and L<"--until">.  For more details, please use the
--help option, or try 'perldoc /usr/bin/pt-query-digest' for complete
documentation.
