When Cacti Are Too Prickly
I'm a clock watcher. I'm a tachometer hound. I'm a speedometer freak. And, as cool as that might seem, more than anything, I love graphs. One of the problems with setting up good SNMP graphs is that not only do they require a server on which to run, but also those servers often are difficult to configure. Programs like Cacti offer incredible features, but for home use, they're usually not worth the effort to configure.
That's where odmon.com comes in. Odmon offers a free service that queries your SNMP devices and hosts Cacti graphs for your local devices. Setup couldn't be easier, and odmon even offers “wizards” to help configure your home router. Part of the process is opening your firewall to its servers, but because you need to provide only read access, and you can limit access to its specific IP address, the security is tolerable—at least for me on my home system.
To set up your free odmon account, go to www.odmon.com. You can be a bandwidth watcher like me in no time!
Odmon offers a wide variety of graphs and the ability to publish them publicly or privately.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
