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.
Web-based fan control (Offline)
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...
Monitor the power in my room (Offline)
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
Gigabit switch statistics (Offline)
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
NEW: Instead of using MRTG
normally by itself, I am now using
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.
Live Webcam (Offline)
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
or it may not be turned on!
Live Host Status (Offline)
This quickly shows which computers in our room are online.
