"ProdAgent" Graphs
Here's some pretty graphs I made recently, I have no idea what they really represent, but I'm sure the under-lying data is completely bogus...

Linux Disk I/O Utilization Graphs
The Linux 2.4 kernel makes counters of disk I/O available via the /proc/partitions "file". As the first step twords graphing our dCache I/O, I wrote a little script to export those counters, served them up via Net-SNMP's snmpd and wrote a NRG discover script to generate graph web pages from the resulting data...

Bargraphs
I have a head cold today. In between blowing my nose and sleeping, I put some work into implementing NRG bargraphs. Here's a proof-of-concept page...

Linux Intel Computing Resources
Today I submitted two graphs to the RRDtool Gallery. The first graph shows that the Linux Intel computing resources available for particle physics research at the University of Wisconsin provides 4.7 CPU years of computing power every day! It's a combination of Condor pools managed by High Energy Physics, the Computer Science Department and the Grid Laboratory of Wisconsin. The other graphs shows the utilization of the CPUs (by particle physics researchers, and other members of the Grid Laboratory of Wisconsin.)
