This is a postgresql based version of Phil Grenspun's Uptime (http://philip.greenspun.com/research/monitoring) that OpenACS use to provide. The site seems unresponive now (20141208).
This was the orginal code that I yanked when PhilG's service was shutdown.
I plan on tweaking it and clean it up a bit. But, I noticed that the code has seem to have been lost.
