Good idea. And easy to implement since the data is really in an PostgreSQL
relational database. It is easy to consolidate by hour.

I will create an Excel <shudder/> spreadsheet from the hourly consolidated
information and send it to a couple of people. They might give me some feed
back on whether they are even interested.

That's what I meant, but my fingers are being contrary this morning.

Right. And the problem is graphing software. I actually have two different
possibilities. One is an Excel spreadsheet. The other is using the R
language. This is a good excuse to learn more about R. R is to Linux/*IX as
SAS is to z/OS. Without the cost. It is _libre_ software.
