We are recently using
tuning-primer.sh and finding it is better than mysqltuner.
cd /usr/local/bin wget https://launchpadlibrarian.net/78745738/tuning-primer.sh chmod u+x tuning-primer.sh
mysqltuner looks like giving wrong suggestions sometimes. Also its not mysql 5.6 ready something which we are using everywhere.
For example, mysqltuner on mysql 5.6 ask us to change value of table_cache variable. It is renamed to table_open_cache. So following mysqltuner suggestion blindly can be risky sometimes.
Though, both are good tools. Use both!
