MySQL monitoring graph is not updating or blank in Munin

Munin is a network resource monitoring tool that can help to analyze and report back all kinds of server statistics. Munin is used to monitor the the performance of computers/servers, networks, SANs, applications, databases, weather measurements and other parameters.

After successful installation, Munin will start colleting required data and will show you the graphs, including MySQL nodes such as MySQL throughputs, MySQL queries, MySQL Slow Queries, and MySQL threads. However, if you restart the server, Munin will fail to monitor MySQL nodes and it will stop showing graphs for MySQL.



Fix for Munin installed by cPanel/WHM



1. Find the path where mysqladmin is installed using one of the following commands:



which mysqladmin

type mysqladmin

locate mysqladmin



The above command will return a path to mysqladmin (i.e. /usr/bin/mysqladmin)



2. Edit Munin configuration file /etc/munin/plugin-conf.d/cpanel.conf and modify the [mysql*] as below:



[mysql*]

user root

group wheel

env.mysqladmin /usr/bin/mysqladmin

env.mysqlopts –defaults-extra-file=/root/.my.cnf



Ensure the env.mysqladmin value is path returned by step 1. Also ensure that /root/.my.cnf contains correct MySQL root password.



3. Restart Munin service:



/etc/init.d/munin-node restart



4. Wait a while for MySQL statistics to be gathered, and check the graphs again.



Fix for the host or server without cPanel Control Panel:



Simply add the “env.mysqladmin /usr/bin/mysqladmin” (ensure that the path is correct according to your system) to the /etc/munin/plugin-conf.d/munin-node file will do the trick.

Ubuntu 10.04.1 LTS Is Available for Download

Mark Shuttleworth, father of the popular Ubuntu operating system, proudly announced a few minutes ago the name and the goals for the next version of Ubuntu. Yes, we are talking about Ubuntu 11.04, dubbed Natty Narwhal and scheduled for release on April 28th, 2011.



"Oh yes, it’s that time of year again, when numerate pollsters make nasal proclamations about the naming of the next next version of Ubuntu. When gazers of balls crystal provide nifty suggestions for new new features and, of course, suitable nomenclature to match."



"And so, we come swiftly to a conclusion: allow me to introduce the Natty Narwhal, our mascot for development work that we expect to deliver as Ubuntu 11.04."  - said Mark Shuttleworth on his personal blog.



For the Natty Narwhal, the development team will focus their efforts on first and lasting impressions. Hopefully, the GNOME 3.0 desktop environment will also be part of Ubuntu 11.04, with the highly anticipated GNOME Shell.



So, what is this Narwhal? Well, according to Wikipedia, it is a medium-sized toothed whale that lives year-round in the Arctic.



"While it may not in fact get you a pony, the world of free software is the platform upon which the future is being built. So the Narwhal, as the closest thing to a real live unicorn, is an auspicious figurehead as we lay down the fabric from which dreams will be woven."



"Dreams of someone’s first PC, dreams of someone’s first million instances in the cloud: whatever your vision of the future, we hope the Natty Narwhal will have something to offer." - said Mark Shuttleworth.



Ubuntu 11.04 (Natty Narwhal) will be the 14th release of the Ubuntu operating system. But, until then, we have another version that should catch our attention and invade our computers, Ubuntu 10.10 (Maverick Meerkat), which will be released on October 10th, 2010. Yes, the perfect 10!



Ubuntu is a Linux distribution for your desktop or server, with a fast and easy install, regular releases, a tight selection of excellent packages installed by default, every other package you can imagine available from the network, and professional technical support from Canonical Ltd and hundreds of other companies around the world.

The Ubuntu team is proud to announce the release of Ubuntu 10.04.1 LTS,the first maintenance update to Ubuntu's 10.04 LTS release.  Thisrelease includes updated server, desktop, and alternate installation CDs for the i386 and amd64 architectures.
