Get your network's weather from Weathermap4RRD

Filed under
Software

When I was investigating the Abilene/Internet2 network sometime back, I found its "network weather map," which graphically shows the load on network segments, to be an interesting tool. I thought something similar could be helpful on our network. Today, we're using Weathermap4RRD to show a high-level graphical representation of our network.

When I started looking for a package that I could use to create a visual weather map of our campus network, I tested a couple of packages, such as Indiana University's WxMap (used to create the above Abilene map). WxMap seemed outdated and bore a restrictive license. By contrast, Weathermap4RRD and Network Weathermap, the Perl package on which it is based, are licensed under the GPL. The project provides a fair bit of documentation on installing and configuring Weathermap4RRD, which is not the case with some of the other projects I had looked at.

One nice feature of Weathermap4RRD is its ability to gather data from either RRDTool databases or MRTG files.

In a Quiet Market for PCs, Chromebooks are Marching Steadily Forward

It's no secret that Chrome OS has not been the same striking success for Google that the Android OS has been. And yet, Chromebooks--portable computers running the platform--have not only found their niche, but they are also introducing a new generation to cloud computing. Chromebooks are firmly entrenched in the education market, where many young users have become used to the convention of storing apps and data in the cloud. Now, according to new research from Gartner, Chromebooks are ready to hit new milestones. Analysts there report that Chromebook shipment growth will be in the double digits this year. At the same time, though, Chromebooks have not become fixtures in the enterprise, replacing Windows PCs. Read more

Server Administration

  • SysAdmins With Open Source Skills Are In Demand
    System administrators play a crucial role in businesses today. They are the individuals responsible for the configuration, support and maintenance of company computer systems and servers. For this reason, they are a popular hiring request, with defense and media companies alike looking for these professionals on Dice. Yet, despite the ongoing demand, finding and recruiting system administrators may be more of a challenge. Data from the U.S. Bureau of Labor Statistics (BLS) found that the quarterly unemployment rate for system administrators was 0.6%, well below the national quarterly average (4.9%) and the quarterly average for all tech professionals (2.1%). Employers thus need to focus more of their recruitment strategies on poaching this talent from competitors.

  • 5 reasons system administrators should use revision control
    Whether you're still using Subversion (SVN), or have moved to a distributed system like Git, revision control has found its place in modern operations infrastructures. If you listen to talks at conferences and see what new companies are doing, it can be easy to assume that everyone is now using revision control, and using it effectively. Unfortunately that's not the case. I routinely interact with organizations who either don't track changes in their infrastructure at all, or are not doing so in an effective manner. If you're looking for a way to convince your boss to spend the time to set it up, or are simply looking for some tips to improve how use it, the following are five tips for using revision control in operations.
