MySQL Performance Tuning Tools: Download, Usage, and Report Analysis (Plus Promotional Offers)

The article introduces several MySQL performance tuning utilities— mysqltuner.pl , tuning-primer.sh , pt-variable-advisor , and pt-query-digest —explaining their purpose, how to download them, basic usage commands, and how to interpret the generated reports.

mysqltuner.pl

A widely used MySQL diagnostic tool that checks configuration, logs, storage engines, security suggestions, and performance metrics.

The report highlights critical items (e.g., memory usage warnings) and provides a "Recommendations" section.

tuning-primer.sh

Another MySQL optimization script that performs a comprehensive health check and offers suggestions.

[root@localhost ~]#wget https://launchpad.net/mysql-tuning-primer/trunk/1.6-r1/+download/tuning-primer.sh

Usage

[root@localhost ~]# ./tuning-primer.sh

The output lists potential issues and corresponding optimization advice.

pt-variable-advisor

A Percona Toolkit sub‑tool that analyzes MySQL variables and suggests fixes for misconfigurations.

[root@localhost ~]#wget https://www.percona.com/downloads/percona-toolkit/3.0.13/binary/redhat/7/x86_64/percona-toolkit-3.0.13-re85ce15-el7-x86_64-bundle.tar
[root@localhost ~]#yum install percona-toolkit-3.0.13-1.el7.x86_64.rpm

Usage

# pt-variable-advisor localhost --socket /var/lib/mysql/mysql.sock

Focus on entries marked with WARN to address configuration problems.

pt-query-digest

Analyzes MySQL slow‑query logs, process lists, or tcpdump captures to produce detailed query statistics.

Typical Commands

# pt-query-digest /var/lib/mysql/slowtest-slow.log
# pt-query-digest --since=12h /var/lib/mysql/slowtest-slow.log > slow_report2.log
# pt-query-digest /var/lib/mysql/slowtest-slow.log --since '2017-01-07 09:30:00' --until '2017-01-07 10:00:00' > slow_report3.log
# pt-query-digest --filter '$event->{fingerprint} =~ m/^select/i' /var/lib/mysql/slowtest-slow.log > slow_report4.log
# pt-query-digest --filter '($event->{user} || "") =~ m/^root/i' /var/lib/mysql/slowtest-slow.log > slow_report5.log
# pt-query-digest --filter '(($event->{Full_scan} || "") eq "yes") || (($event->{Full_join} || "") eq "yes")' /var/lib/mysql/slowtest-slow.log > slow_report6.log

The resulting report is divided into three parts: overall statistics, query‑group statistics, and detailed per‑query metrics (overall count, time range, unique queries, total/average times, percentiles, etc.).
