Network Monitoring with Zenoss: A Reluctant Administrator's Guide
My household now has four physical computers, one of them dual boot. All are on a single internal Local Area Network. I also have two computers sitting in a box, which will probably be added to this mess soon, plus my wife plans to get a laptop. Like it or not, I now manage a network bigger than many small businesses! Surely, there must be a way to automate this mess?
Enter Zenoss…
The Problem
I’ve been very conservative about setting up my network. Our computers vary in ages from about three years to about eight years—we have so many, not because we buy a lot of computers, but because we never throw them away: with two adults and three kids, there’s just too much demand. Several of the computers are either hand-me-downs, or newly-assembled systems made from hand-me-down parts. Even the new ones are what professional administrators would dismissively dub “whiteboxes”—do-it-yourselfer systems assembled from major components. The edge router that connects to our line-of-sight internet uplink is an off-the-shelf appliance, which is fortunately very low-maintenance. Figure 1 shows the network configuration, and some of its oddities (one of the boxed computers is included in this figure).

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
