Nagios - Open Source Network Monitoring
Nagios is an Open Source solution to monitor complex IT infrastructures. Nagios can be used to perform alive checks to ensure the availability of networked systems. It is also possible to use Nagios for performance and capacity analyzes.
I write about Nagios cause I use it since several years. Over the time I collected much knowledge about Nagios and the surrounding projects. I contribute actively to the community writing and publishing plugins and maintaining the NagVis addon.

It’s been a while since my last post. I have so many different projects running that I had no time to write about them. So you have to be content with this short note.

There is not much progress in Nagios development – it is visible since a couple of years. This is what it looks like when one checks out the Nagios Core sources, mailing lists and so on. This could lead us to the question: Is there something happening under the surface which we don’t see? Maybe one day a brand new Nagios Core 4.x is released as big bang and from one day to the other everything changes? Well, I don’t think so.
But why do we care about the development of the Nagios Core so much? Do we really miss important features there?
Nagstamon has been released in version 0.9.5. I haven’t written about Nagstamon before, so for a brief introduction: It is a program to display Nagios status information on your desktop in form of lists. The lists are mostly equal to the “problem lists” in Nagios. Nagstamon comes with a graphical user interface which is based on GTK. Nagstamon is highly portable, it works on Linux with KDE/Gnome, Windows 2000 to Windows 7, Mac OS X, and so on. Continue reading to see why I am writing about this release…
You think Nagios is rusty old stuff? Certainly not! Great things are happening around Nagios. One of these brand new innovations is OMD – The Open Monitoring Distribution. It has been released in version 0.46 yesterday. OMD is THE way of installing and managing Nagios installations these days. It brings you multi instance setups, one [...]
Oh dear. So many new thing but simply not enough time to write about it…
I wanted to drop a short note about the current OMD version. It has been released several days ago but I think it’s worth to write about it since OMD is a very nice solution for installing and updating Nagios plus addons easily.
OMD is NOT yet another linux distribution! OMD stands for nothing else than open monitoring distribution.
The OMD is package based on Nagios and a collection of Nagios plugins/addons which are bundled together to give a quick start to Nagios & Co. The difference to other tries to set-up such a project is that this approach is completely open – no real limits. This will be the next big step in evolution of Nagios!
