Tips from the trenches for over-extended MySQL DBAs

This post is a follow-up to my November 19 webinar, “Tips from the Trenches: A Guide to Preventing Downtime for the Over-Extended DBA,” during which I described some of the most common reasons DBAs experience avoidable downtime. The session was aimed at the “over-stretched DBA,” identified as the MySQL DBA short of time or an engineer of another discipline without the depth of the MySQL system. The over-stretched DBA may be prone to making fundamental mistakes that cause downtime through poor response time, operations that cause blocking on important data or administrative mishaps through the lack of best practice monitoring and alerting. (You can download my slides and view the recorded webinar here.)

Optimizing MySQL for Zabbix


This blog post was inspired by my visit at the annual Zabbix Conference in Riga, Latvia this year, where I gave a couple of talks on MySQL and beyond.

It was a two day single-track event with some 200 participants, a number of interesting talks on Zabbix (and related technologies) and really well-organized evening activities. I was amazed how well organized the event was and hope to be invited to speak there next year as well.   (Just in case you’re not sure what Zabbix is, it is an enterprise-class open source distributed monitoring solution for networks and applications)

I must secretly confess, it was also the first conference …

Percona Monitoring Plugins 1.1.3. Addressed CVE-2014-2569.

Percona is glad to announce the release of Percona Monitoring Plugins 1.1.3.

Changelog:

* Introduced more secure location of PHP script configs to harden a Cacti setup
* Addressed CVE-2014-2569

We have introduced a more secure location /etc/cacti/ for PHP script configs. Earlier, the only way was to keep .php.cnf configs inside of scripts/ folder which falls under the web directory of Cacti setup, thus provides a potential security vulnerability. We strongly recommend to move all .php.cnf files from /usr/share/cacti/scripts/ to /etc/cacti/ and also harden your Cacti setup.

A new tarball is available from …

Monitoring MySQL

Ronald Bradford wants to know what kind of Monitoring you use..
He specifically wants to know about Alerting tools

There's different cases , looking at it from a full infrastructure point my current favourite is Zabbix or good old Nagios,

But when looking at it from a debugging perspective you have MySQLAR or Hyperic, but those aren't in the alerting list.

However, when you are building HA clusters, you have custom scripts running either from mon or from pacemaker ..

Still .. Ronald probably wants more input :)

Do we want an Open Source MySQL Monitoring tool ?

Matt Reid wants to know what we want in an Open Source MySQL monitoring solution ?

He is working on the second incarnation of Monolith and wants input from the MySQL community.

Now for me the bigger question is if we want an isolated tool that runs stand alone, or a tool which we can integrate it in something we already have.

To me there is a difference between a tool that I want to use to debug my environment, such as Mytop or MySQL Activity Report, in that case I need some tool that quickly installs with little dependencies and little impact.

On the other side I want a tool that is constantly there, that tells me about trends and performance history. But there I don't want an isolated toool, I want something fully integrated where I can correlate different measurements from disk io, memory usage etc , that tool should also tell me about the …

Zabbix 1.5.4 Woes

I was trying to check out the new Zabbix beta's when I ran into a couple of problems. Mostly missing dependencies but also some bugs.

The big troubles start when trying to install the frontent.
It seems like php code shipped in the last release might well work when you are upgrading but it fails when you are doing a fresh install. As I never got a Setup Wizard.

The clue is to get the most recent code from their SVN repo svn co svn://svn.zabbix.com/trunk , that actually allows you to run the setup wizard.

If you are installing the latest RPM's they are also not really requiring all the dependencies you need to run the frontend.

yum/apt-get install php-bcmath php-pear

Will get you a step further.

Another thing is the new password policy.. it seems the Admin/blank is gone.
I have no clue what the new password is but you are encouraged to set it yourselve in the mysql database
