Collect and keeps up to date the system information using sysinfoupdate

In 2005 I was looking for ways to auto collect information about a Linux server. The information was to be used in case of bare bones recovery. I didn't found a satisfactory program so I created one, sysinfoupdate. This program have been growing long this years and now is a system that helps to maintain a diary of a Linux Installation. The diary records all the important changes the sysadmin does to the system. This records can be used during recovery after a broken hardware or to detect what change may be causing a malfunction, for example.

It's use is very simple, create a diario directory in your home directory, for example /root/diario, and then run sysinfoupdate. Inside diario you will find a group files with textual information about your system. It works best if you run it as superuser and you keep track of the changes under a version control system, like subversion or git.

You can download the Debian package here or download the source from here.

A Selection of Talks from FOSDEM 2012.

It was only some days ago that I made the decision to go, for the first time to the FOSDEM (Free and Open Source Software Developers' European Meeting). That was a good decision. The keynotes and the maintracks were very good, with good presentations and contents.

It is a big conference and this year, is not an exception. With 429 speakers and 430 talks at 21 rooms in only two days. It's impossible to see all the presentations. The only 5 rooms with a video camcorder to tape the talk, where: Janson, K.1.105, Ferrer, H.1301, H.1302. It's very dificult to choose what talks to see, what talks to see later in video and what talks to loose. What I leave here is my selection of talks. This selection is representative of my tastes, not of the quality of the presentations. I will give links for material that is available now. I will do periodic updates when the new material is available, the video or the slides.

Nagstatmon help monitor network and servers using nagios

Monitoring a network or a group of servers using nagios have some problems. Receiving alarms by email or have a browser with a open page to the nagios site is an option that don't fit well in the work flow of some people.

Nagstatmon is a program that solves that problem. It opens a small window or icon on a taskbar of your desktop and show how many alarms are active. When an alarm triggers you can see where and what kind of alarm and easily open a connection for managing the equipment in fault.

This program is available in Debian testing (squeeze) but the package is compatible with Debian stable (v5.0, lenny).

The homepage for the software is http://nagstamon.sourceforge.net/
