Nagios check_dell_warranty Plugin Updated

published on Thu, 05/28/2009 - 16:27

It's been blogged about recently how cool the check_dell_warranty plugin by Erinn Looney-Triggs is. It solves a very real problem for us - sometimes servers run so well you forget to make sure that you renew your support contracts. However, it wasn't quite right for us - we have some older Dells that have RHEL 4 with an older (incompatible) python on them still. Also, the plugin wouldn't work without configuring sudo. Well, like any other sysadmin would do, I fixed it!

The Nagios Fork: Did Two Wrongs Make a Right???

published on Tue, 05/12/2009 - 23:06

It's an item that I feel hasn't got much press, at least in the limited RSS entries I've had time to scan lately: Nagios has been forked. I've been using Nagios long enough that I actually used NetSaint for a bit, so I have some mixed feelings about Icinga. In general, I'm all for forks when they are indeed needed - FOSWiki is a great example. But forks shouldn't be taken lightly, in many ways they are like a divorce - they should be a last resort, not a quick way out. Personally, I think that the fork will ultimately either fail or merge back into Nagios, but read on for why I think the Icinga fork is a case of two wrongs making a right.

Installing NRPE 2.12 from source as a SMF managed service in Solaris 10

published on Thu, 05/07/2009 - 08:22

Installing NRPE on Solaris 10 involves just a bit more than your normal './configure && make && make install' routine. However, all the dependencies are likely present on a freshly installed system, you just have to tell NRPE where to find it. There's one file you need to patch, and then it will install. From there it's easy to plug into SMF!

Compiling Nagios Plugins and NRPE on Solaris 10 with Sun Studio

published on Fri, 07/06/2007 - 10:56

We have some Sun T1000's running Solaris 10 that we are going to deploy as web servers. By compiling Apache from source using the Sun Studio compilers, you get a huge boost in performance because of the compiler's built-in optimizations for the Niagra processor.

Before deploying them, I needed to get NRPE setup, which requires that the Nagios plugins be installed. Once setup on the client side, I can point our Nagios server at the webserver and get notified of hardware issues, disk usage, load averages and what not.
