MySQL Enterprise Monitor 3.0: viewing Query Analyzer for 5.5.x servers.

So, the good thing about MEM 3.0 is that it’s agentless, i.e. you don’t need an agent to use Query Analyzer data and see when performance is at it’s worst and dive into the offending SQL’s and explain plans to see what’s happening.

That’s great, however, sometimes it’s not always an easy road to migrate to 5.6 and even if you’re doing so, there’s nearly always a time when you want to continue viewing things in 5.5.x and compare performance between the 2.

The thing is, that in order to see the Explain Plans we need 5.6.14 or upwards (and setting “UPDATE performance_schema.setup_consumers SET enabled = ‘YES’ WHERE name = ‘events_statements_history_long’;” ).

So, here’s how to do it:

MySQL Enterprise Backup 3.10: Teasing compression.

Ok, so I wanted to look into the new compression options of MEB 3.10.

And I would like to share my tests with you. Remember, they’re just this, tests, so please feel free to copy n paste and obtain your own results and conclusions, and should I say it, baselines, in order to compare future behaviour, on your own system.

An Oracle Linux 6.3 virtual machine with 3Gb RAM, 2 virtual threads, on a 1x quad core, windows laptop. Not pretty, but hey.

So, these tests are solely about backup. I’ll do restore when I get some *more* time.

–use-tts backup & restore

In addition to my recent post, I just had to go into using the –use-tts for specific tables and selective backup sets.

As all my schemas were employeesn, I thought it would be a good idea to run:

mysqlbackup -uroot --socket=/tmp/mysql.sock --backup-dir=/home/mysql/MEB/restore \
--with-timestamp --use-tts --include=employees* backup

MySQL Utilities: copy, replicate, show, failover… over and over again.

So, after installing Workbench 6.0.7 on my pc, and playing around with the MySQL Utilities that are included, I thought I’d do similar to what others have done (Thanks Tony D.) and share my experience on how I’ve used them. If you haven’t installed Workbench before, you might want to check your platform first: http://www.mysql.com/support/supportedplatforms/workbench.html.

So, even if you’re not using any of the recent versions and editions of Workbench (Utilities comes with all of them, Tools menu -> “Start Shell for MySQL Utilities“) you can just download the standalone scripts on a Linux machine. Flexibility being the name of the game again.
