pt-query-digest安装与使用
官方：https://www.percona.com/doc/percona-toolkit/2.2/pt-query-digest.html
wget percona.com/get/pt-query-digest
chmod u+x pt-query-digest
mv pt-query-digest /usr/bin/
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.
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 0)
--charset=s -A Default character set
--config=A Read this comma-separated list of config files;
if specified, this must be the first option on
the command line
--[no]continue-on-error Continue parsing even if there is an error (
default yes)
--[no]create-history-table Create the --history table if it does not exist (
default yes)
--[no]create-review-table Create the --review table if it does not exist (
default yes)
