Monitoring a RAID controller on a remote machine with MRTG

May 17th, 2014 No comments

In this post, I’ll show you how, using MRTG and xinetd, I set up monitoring of the temperature of a RAID controller on a remote machine.  I use the same technique to also graph the temperatures of the individual hard drives in the RAID array as well, and it can be used to graph just about anything.

Fixing queues display in trixboxGraph

March 21st, 2012 No comments

I recently installed the trixboxGraph package to my trixbox CE asterisk PBX, and discovered that the functions related to queues were borken. I investigated and fixed it. There are two lines that need updating in tb-trixboxgraph/index.php.

KF7TZO

It’s official – I’m a ham. I’ve been accused of it for years, and now you’ve all been proven right.

I took the technician class amateur radio exam on February 4th, and aced it. 100%! My call sign (KF7TZO) was granted on February 13th. You will probably find me on the 2 meter band most of the time. Watch for me on aprs.fi, too.

Sometime in the nearish future, we’re going to be launching a weather balloon, and tracking it via APRS, which is a packet technology that uses amateur radio frequencies. There will definitely be more to come on that project.

MyMovies – Bulk Path Change for Online Titles

June 12th, 2011 5 comments

My Home Theater PC has a 2TB RAID array, on which I was storing movies, music and recorded TV. After upgrading from my analog tuners to a Ceton quad tuner board, which gave me access to more programming as well as HD programming, I found that my 2TB array was starting to get a little too close to full, a little too often.

(Great) Tail of a Grackle

May 22nd, 2008 No comments

The wind here in Las Vegas has been pretty strong the last couple of days. It’s often windy here (deserts are like that), but we’ve seen particularly strong gusts for the last day or two.

Besides intermittent cable TV and internet service, another (often overlooked) casualty of such winds is the wildlife. Read more…
