+<p>At work, we have a few hundred Linux servers, and with that amount
+of hardware it is important to keep track of when the hardware support
+contract expire for each server. We have a machine (and service)
+register, which until recently did not contain much useful besides the
+machine room location and contact information for the system owner for
+each machine. To make it easier for us to track support contract
+status, I've recently spent time on extending the machine register to
+include information about when the support contract expire, and to tag
+machines with expired contracts to make it easy to get a list of such
+machines. I extended a perl script already being used to import
+information about machines into the register, to also do some screen
+scraping off the sites of Dell, HP and IBM (our majority of machines
+are from these vendors), and automatically check the support status
+for the relevant machines. This make the support status information
+easily available and I hope it will make it easier for the computer
+owner to know when to get new hardware or renew the support contract.
+The result of this work documented that 27% of the machines in the
+registry is without a support contract, and made it very easy to find
+them. 27% might seem like a lot, but I see it more as the case of us
+using machines a bit longer than the 3 years a normal support contract
+last, to have test machines and a platform for less important
+services. After all, the machines without a contract are working fine
+at the moment and the lack of contract is only a problem if any of
+them break down. When that happen, we can either fix it using spare
+parts from other machines or move the service to another old
+machine.</p>
+
+<p>I believe the code for screen scraping the Dell site was originally
+written by Trond Hasle Amundsen, and later adjusted by me and Morten
+Werner Forsbring. The HP scraping was written by me after reading a
+nice article in ;login: about how to use WWW::Mechanize, and the IBM
+scraping was written by me based on the Dell code. I know the HTML
+parsing could be done using nice libraries, but did not want to
+introduce more dependencies. This is the current incarnation:</p>

+<p>Here are some examples on how to use the function, using fake
+serial numbers. The information passed in as arguments are fetched
+from dmidecode.</p>
+
+<pre>
+print get_support_info("hp.host", "HP ProLiant BL460c G1", "1234567890"
+ "447707-B21");
+print get_support_info("dell.host", "Dell Inc. PowerEdge 2950", "1234567");
+print get_support_info("ibm.host", "IBM eserver xSeries 345 -[867061X]-",
+ "1234567");
+</pre>
+
+<p>I would recommend this approach for tracking support contracts for
+everyone with more than a few computers to administer. :)</p>
+
+<p>Update 2009-03-06: The IBM page do not include extended support
+contracts, so it is useless in that case. The original Dell code do
+not handle extended support contracts either, but has been updated to
+do so.</p>
