At work we have been looking for tools to monitor MySQL and at the same time provide as much diagnosis information as possible upfront when an alarm is triggered. After looking around at different options, I decided to test MONyog from Webyog, the makers of the better known SQLyog. Before we go on, the customary disclaimer: This review reflects my own opinion and in no way represents any decision that my current employer may or may not make in regards of this product.
First ImpressionYou know what they say about the first impression, and in this where MONyog started with the right foot. Since it is an agent-less system, it only requires to install the RPM or untar the tarball in the server where you're going to run the monitor and launch the daemon to get started. How much faster or simpler can it be? But in order to start monitoring a server you need to do some …

If you have been wondering why the overview and graphs pages say “no data to display” on the graphs when you first install Kontrollbase, it’s because there’s no data in the database being returned from the queries that generate the graphs – this is because a new install has no data to graph. This has […]

Last week I presented “From support services to software services – the evolution of open source business strategies” at the OSBC event in San Francisco.

The presentation was effectively a work in progress update on our research into the various strategies employed by technology vendors to generate revenue from open source software.

It included a partial explanation of my theory that those strategies do not exist in isolation, but are steps on an evolutionary process, and also introduced our model for visualizing the core elements of an open source-related business strategy.

I provided a number of examples of how the model could be used to compare the strategies of various open source businesses. …

Berkeley DB (BDB) is undoubtedly the workhorse among the opensource embedded database engines. It started as a university project in the mid-eighties and was further developed by Sleepycat Software, until it got acquired by Oracle in February 2006.

I had the impression that BDB had lost a lot of its popularity among opensource developers to SQLite in recent times, which has evolved into becoming the default choice for developers looking for an embedded data store. I'd assume primarily because the code is not released under any particular license, but put in the public domain …

If you’ve noticed that your recent upgrade did not go as planned and now the application does not load – please check this page: http://wiki.kontrollsoft.com/wiki/UpgradingReleases for notes on upgrades between versions. Typically you need to execute a SQL file against the current schema to bring it up to date. If you have any questions please [...]

Last week Solutions Linux / Open Source event was held in Paris.

Kuassi MENSAH (Head of Product Management Database Technologies, Oracle Corporation) presented the open source Oracle strategy. Linux, MySQL, virtualization, GlassFish, Eclipse, dynamic scripting languages ,... etc . It was well received by the audience. Knowing that MySQL organization will be kept safe in Oracle is perceived as a nice move.

Florian Haas(LINBIT) gave a tutorial on DRBD and did some demos with NFS and video streaming. And of course he reminded people that now since Linux 2.6.33, DRBD is officially integrated into the Linux kernel source. DRBD making the push for mainline Linux kernel is going to make HA easier.

I’m pleased to announce the first release of Kontrollcomm – “The Server Command Automation Interface” is a web-based application that automates remote command execution on linux and unix based servers. There are three main areas of the application: Hosts, Templates, and Commands. The use is very simple: all of your hosts are setup in the [...]

This is a small revision and will only be available through SVN. However, it is an important one to speak about as it solves a former issue when running the application on a screen smaller than 1024px wide. While most users may not have noticed this since they have larger monitors it has been noticed [...]

I’ve recently been migrating my wiki/documentation for Kontrollbase to Trac. For those that are not aware, Trac is a web-based documentation/wiki/Subversion tool that is used by countless number of software projects. Subversion, of course, is a software collaboration and code management repository that manages branches/tags/trunk files with revision control. It’s one of the most heavily used open-source code repositories available. Given that I use SVN (subversion) for all of my software applications and am now using Trac, the book “Managing Software Development with Trac and Subversion” by David J Murphy comes as a useful and great resource for integrating these two useful tools. …
