Dave Williams' presentation on embedding Nagios on a RaspberyPi
The presentation was given during the Nagios World Conference North America held Sept 25-28th, 2012 in Saint Paul, MN. For more information on the conference (including photos and videos), visit: http://go.nagios.com/nwcna
First some background about me Then a description of the RaspberryPi – components & the intenet behind it Pretty much a blow by blow description of how to install / compile Nagios on Squeezy on the RasPi Using mod_gearman distributing Nagios tasks using the Raspi Hopefully show you it working… What is the future for this technique & technology Wrap up & Questions
Over 35 years working in the IT industry Coding real time systems and then on to Operating system support GeCOS & Transaction Processing – assembler / machine code Network Processor software development Customer Facing IBM Mainframes MVS / VM – SNA VTAM / NCP – Bureau Environment / Service Orientated Bull – Honeywell Bull / CIIHB / Honeywell - worked at R&D in Toronto / Minneapolis / Grenoble
Bull Toronto was R&D centre for system monitoring SNMp & Graphical systems Openview on HP kit for IBM Bureau ISDN / Dial-In systems (from FT / Legal document systems) Netview for IBM SNA networks Open Master Openview like system written by Bull – AIX based Saw Netsaint 0.6 finally complied by Chris Rothecker, tried it decided I could do a better port – did it. – built AIX installp file that contained everything GD etc. released via the Bull freeware site. Followed project and continued to work with Nagios under AIX. Later evangelized Nagios in Bull and worked on the Linux based versions
The idea behind a tiny and cheap computer for kids came in 2006, when Eben Upton and his colleagues at the University of Cambridge’s Computer Laboratory, including Rob Mullins, Jack Lang and Alan Mycroft, became concerned about the year-on-year decline in the numbers and skills levels of the A Level students applying to read Computer Science in each academic year. From a situation in the 1990s where most of the kids applying were coming to interview as experienced hobbyist programmers, the landscape in the 2000s was very different; a typical applicant might only have done a little web design. Something had changed the way kids were interacting with computers. A number of problems were identified: the colonisation of the ICT curriculum with lessons on using Word and Excel, or writing webpages; the end of the dot-com boom; and the rise of the home PC and games console to replace the Amigas, BBC Micros, Spectrum ZX and Commodore 64 machines that people of an earlier generation learned to program on. There isn’t much any small group of people can do to address problems like an inadequate school curriculum or the end of a financial bubble. But we felt that we could try to do something about the situation where computers had become so expensive and arcane that programming experimentation on them had to be forbidden by parents; and to find a platform that, like those old home computers, could boot into a programming environment. From 2006 to 2008, Eben designed several versions of what has now become the Raspberry Pi; you can see one of the earliest prototypes
Wheezy has optimisation for the floating point processor and will use the dynamic overclocking firmware

Inspired by the low-cost computing power of the Raspberry Pi, a team at the University of Southampton has used the ARM-based Linux computer-on-a-board as a building block for a low-cost supercomputer—racked and stacked using Lego blocks. And they’ve published a step-by-step guide for anyone interested in creating their own Raspberry Pi high-performance computing “bramble." Led by Professor Simon Cox, with Lego expertise lent by Cox’s 6-year old son James (who spent the summer learning to program on the Raspberry Pi using Python and MIT's Scratch), the team used 64 Raspberry Pi computers, each equipped with a 16-gigabyte SD card to construct a functioning computing cluster for under £2,500 (a bit over $4,000)—not including the Ethernet swtiches used to connect the nodes.

The weather station that I’ve been using since November 2010 is one I bought from Maplin. They usually sell for about £125 but a couple of times a year they reduce them down to between £50-£70. N96FY USB Wireless Weather Forecaster. At the time of writing this they’ve got it reduced to £69.
