Enterprise Monitor: “Add Bulk MySQL Instances” 50 in 1-click.

Carrying on with my MySQL 5.7 Labs Multi Source Replication scenario, I wanted to evaluate performance impact via MySQL Enterprise Monitor.

Whilst I opened my environment, I remember that I had generated lots of different skeleton scripts that allowed me to deploy the 50 servers quickly, and I didn’t want to add each of my targets 1 by 1 in MEM. So, I used one of the many features available, “Add Bulk MySQL Instances”.

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.

MEM 3.0: Getting started

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

OL 4 MySQL: Extending my VM’s root f/s online

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.

Enterprise Monitor-ing the Raspberry Pi & MySQL Cluster

So, now I’ve got my Raspberry Pi’s tested, and running MySQL Cluster we’ll need some form of checking it’s up and running, as with the rest of our MySQL servers.

Monitoring via a Remote Agent

First issue, of course, is that, with my existing MEM console, I have no need to re-install MEM, but rather want to deploy an agent so that I can monitor the MySQL Cluster.
This poses it’s first problem, as there isn’t an ARM-ready agent software available. Remember, it’s not a supported platform. So what can we do? Setup a remote Enterprise Monitor agent, so that, we can monitor the MySQL Cluster, albeit at the sacrifice of not having the agent local on each Raspberry Pi, and hence, not be able to capture the o.s. data.
