- This is a program I wrote that generates a nice-looking weather map that shows the traffic flowing through different links on a network. Has on-the-fly animation capability and detailed traffic history. Uses MRTG to collect the data.
- Combine a little Perl, some old X-10 equipment I had laying around, and 2 sets of large box fans...
- This controls the fans in the room I live in (only authorized users can turn them on or off, everyone else can only view their current status.
- Offline for the time being...
- This uses MRTG combined with some Perl to generate nice-looking graphs of all sorts of power statistics in our room, and keep an eye on status of the UPS connected to my computers.
- Power Outage Calender (4 month view) (Offline)
- A little Perl script I wrote that makes an HTML calender of the past several months and shows number of power outages for each day.
- Here I am actually using MRTG as it was supposed to be used, graphing the traffic to the various ports on my 4-port 1000BaseSX switch
- Our campus now has gigabit fiber to the desktop, so I have this little (well, 19" rack-mountable and 14 lbs...) beauty to connect my computers...
- NEW: Instead of using MRTG normally by itself, I am now using RRDtool, which is made by the same people as MRTG. This allows the data to be updated every 1 minute (instead of 5 with plain MRTG), and keeps the 32-bit counters from wrapping more than once per update. Also, these graphs are generated on-the-fly instead of when the data is collected.
- An NTSC camera connected to a Bt878-based capture card = instant webcam
- Updates every 10 seconds
- Note: the subject of this webcam varies often, including:
- some of the (caged) rodents living in our room
- a view outside of Leutner
- me (rarely!)
- or it may not be turned on!
- Live Host Status (Offline)
- This quickly shows which computers in our room are online.
- LaserJet Status
- Check the status of my printer
- LaserJet pagecount stats
- Check the current pagecount and totals for my printer
