Mysql logfile analysis

General log

This will focus on general log analysing.

Will be using two fantastic tools:

pt-query-digest

Sample output for a general log analysis:

pt-query-digest --type=genlog --filter '$event->{db} eq "wp-site42"' mysql-general.log

mysqlsla

./mysqlsla --log-type general mysql-general.log
