MySQL Marinate, a FREE basic MySQL training course led by Sheeri.
Combining some of the utilities we’ve seen so far, it’s possible to get some interesting analysis from your error log:
grep -vE "(Version|ERROR)" /var/log/mysql/error.log | cut -d ':' -f 1 | sort | uniq -c
Comma-Separated Values Storage Engine
CSV Manual page
Sample CSV table CREATE statement:
CREATE TABLE t1 (i1 INT NOT NULL, s1 VARCHAR(20) NOT NULL) ENGINE=CSV;
Statistics gathering script - could easily be modified to send output to a CSV table/file.

Where you can see us
MySQL Marinate starts January 1st, 2013. It is a virtual self-study course learning MySQL which both Gerry and Sheeri will be helping lead.
Gerry will be at the January Seattle MySQL meetup group which will feature Lisa Phillips of Twitter talking about how Twitter uses MySQL. The Seattle meetup group will also discuss the current topics in MySQL Marinate, so it's a live, in-person way to get questions answered.
Sheeri will be at the January Boston MySQL meetup group on Monday, January 14th from 7-9 pm. The topic is NuoDB, an emergent database that is 100% SQL, 100% ACID, and scales out elastically on decentralized resources in the cloud, on-premises, or both.
