Time to install MEM 3.0, and get its built-in agent working.

[ If you want some tips on What's New, have a look here. ]

I’ve downloaded the Monitor Server and the agent zipped s/w for Linux & Win from http://edelivery.oracle.com:

mysqlmonitor-3.0.0.2887-linux-x86-installer.bin
mysqlmonitoragent-3.0.0.2887-linux-glibc2.3-x86-32bit-installer.bin
mysqlmonitoragent-3.0.0.2887-windows-installer.exe

The Monitor install

So, on my Oracle Linux machine:

./mysqlmonitor-3.0.0.2887-linux-x86-installer.bin

It all installs fine. No issues, if you’re used to MEM 2.3.

Double check your configuration_report.txt :

MySQL Enterprise Monitor (Version 3.0.0.2887 : 3.0.0.2887)

Here are the settings you …

Just a quick post to note that the content from my hands-on lab at MySQL Connect (“MySQL Enterprise Features in Practice”) has been uploaded to the content catalog, and can be found here.  This includes the 36-page lab manual and example commands and programs (mostly in Java; the package includes both compiled and source code).  For those who attended the lab, this is an opportunity to complete the exercises we didn’t get to in the 2.5 hours, and for those who missed it, an opportunity to learn more about the features and capabilities of key MySQL Enterprise products and features such as MySQL Enterprise Audit plugin, MySQL Enterprise Monitor and MySQL Enterprise Security (PAM plugin).  I hope to expand on the lab content …

MySQL Enterprise Monitor (MEM) 3.0 is a huge improvement over MEM 2.x and I really hope you'll take a look at it.  My goal here is to tell you about a new feature that is near-and-dear to my heart--looking at a server in the context of a group of servers.
Why is this important?
As many of you know it's important that each server in a replication topology have a unique server_id (each slave, really).  It's not hard to give each server a server_id, but it's also very easy to forget this step, especially if you're cloning a slave from another slave, or if you're under the gun to do something quickly.  It's surprising how often our Support engineers and consultants tell us they see this in the field.
The problem is that if more than one server has the same server_id as another, problems can occur that may be difficult …

As a follow-up to my earlier post describing the process to create custom Advisors for MySQL Enterprise Monitor, this post will demonstrate how to create custom graphs to track metrics over time. The password policy scripts I introduced earlier will again be the basis for the data used in this post.

Collecting new data

Similar to the custom Advisor created in the earlier post, creating a custom graph starts with custom data collection.  Why can’t I just use the data collections I defined in the earlier example?  Because there’s a restriction on using multiple custom data types (defined as namespace+classname combinations) in a single graph, and in the earlier example, I used …

Quite some time ago, I published scripts to implement password policies for MySQL, and promised to show how to expose violations of that policy via MySQL Enterprise Monitor (MEM).  That stalled somewhat with other objectives, but I want to revisit it now that MEM 3.0 is GA.  If you haven’t tried MEM 3.0 yet, consider doing so – it’s quick and easy to set up.

Many people don’t realize that MEM can be extended to monitor things beyond MySQL Server health, including visibility into application state as observed from the database.  In part of the hands-on-lab I recently led at MySQL Connect, we …

After a slight delay (travel and catching up with “real work”), I’ve now uploaded the talks that I gave at MySQL Connect and Oracle Open World.

They are available on my Presentations Page, and inline below for convenience. The “Introduction to MySQL Enterprise Monitor” talk was actually a full demo, but there are some screenshots of MEM 3.0 in there if you’re interested in seeing a high level picture of what it looks like now.

Thanks to all that attended my talks, I got a lot of good questions and feedback!

Ok, so after all the things that have been announced @MySQLConnect, I’ve got to play around with them. First stop: space (no.. not ‘the final frontier’).

I need more space on my f/s to get installing. I was a bit of a scrooge when I created my Oracle Linux virtual machine, so now I’m paying the price.

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_ol63uek01-LogVol01
                      7.1G  5.7G  1.1G  85% /

As I’m using Virtual Box, I’ve added a new SATA Controller vmdk of 10G, SATA Port 1 and then start it up.

fdisk -l

Will be able to identify the new & unused partition:

[root@ol63uek01 ~]# fdisk -l

 255 heads, 63 sectors/track, 1044 cylinders

The MySQL Connect content catalog is published, and I’ll be leading a hands-on lab on MySQL Enterprise Features in Practice [HOL9787].  If you have wondered how to get the most out of the features of MySQL Enterprise subscriptions – whether you are an existing Enterprise customer or not – this lab is for you.  We’ll help you understand the benefits of the various components of the MySQL Enterprise subscription as you install, configure, demonstrate and use the …
