Actually, it is the user that I am logged in as that created the

How often to OPTIMIZE?
The Short answer: Never.
The Long answer: A _few_ tables _may_ need OPTIMIZE _sometimes_.
One test: Is the "free" space (according to SHOW TABLE STATUS or equivalent
information_schema stuff) is > 10%, then OPTIMIZE. Maybe. However... That
math works OK for MyISAM,
optimizeall() is simply called from a cron script
the mysql-wrapper does not exist in public but you get the table
overhead with "SHOW TABLE STATUS" as you can see below

Hi Reindl,
I would like to implement your strategy of optimizing tables. Can you
please share how are running these scripts? Where does the
mysql-wrapper-class exist? And what parameters need to be passed?
Thanks

Hello Antonio,
As Reindl said, it is recommended but it shouldnt be done just
everyday if your tables are quite big and you use query cache.
If you do have lot of writes and deletes (depending on what you
consider a lot), your table will indeed have lot of 'blank rows' which
eat disk space.

Hello Manuel,
Exactly. My objective doing performance MySQL it isn't to free disk space
(it isn't the problem). I would like to get a good performance using cache
and setting good values to configuration variables.
I will defrag tables once per month.
Best regards,
Antonio.
Ok. Thank you very much.
Best regards,
Antonio.

it is recommended but not permanently and not blindly

Hi Reindl,
Thanks for your reply.
So, is it not necessary (not recommended) to defragment tables if I have a
lot of write operations (writing or deleting)?
Best regards,
Antonio.

Hi everybody,
Once I have done the defragmentation of MySQL tables, mysql-tunner.pl suggests
me do it again. Is this correct? I think that the idea is that in the
result of the script there are not fragmented tables ...
Any ideas?
Thank you very much.

Hello,
"--syslog" is option of "mysql" command line client and it works in my
environment.
Do you put [mysql] section in your my.cnf?

Hi,
You can check out the McAfee MySQL Audit Plugin at:
https://github.com/mcafee/mysql-audit
It is an open source plugin providing audit capabilities for MySQL. It can be
used to log executing commands. It can log to a file or over a unix domain
socket to syslog-ng.
Best,

Hi All.
I have a production setup of four databases connected with
replication. I would like to log every command that clients execute
for auditing.
