I'm kinda of a statistics nut. I like breaking stuff down into cold, hard, unforgiving numbers. As a corollary to being a slight stats nut, I am also very wary of any and all statistics (I'm sure you've heard the quote before.... "lies, damned lies...") Just look at the ITS Dashboard. There's a lot of meaningless statistics in there that could be used to "justify" a lot of different perceptions of their "meanings" (i.e. incorrect trending). In addition to the meaningless stats, there are some in there that are downright misleading.
But for all you people that like stats and for some reason like to look at pretty graphs, I recently took a little bit of time and poured over the mail server collecting some numbers. The numbers I was looking for are:
- How much email storage (in megabytes) do our typical users use?
- What about faculty — how much do they use?
- What about students?
Well, here are the numbers (sorry about the poor quality of the graphics (click through on the picture to see the larger images), I used a small perl script to gather the numbers but crunched them and produced the charts in Excel):
In addition to that numerical goodness, I created some fun ITS Dashboard stats tracking the number of persons (broken down by roles again) forwarding their Case email to GMail:
- Email accounts forwarded to GMail - students
- Email accounts forwarded to GMail - staff
- Email accounts forwarded to GMail - faculty
- Email accounts forwarded to GMail - total for employees, students, and general affiliates (excluding alums)
There are a lot of different ways to interpret those GMail forwarding stats. My particular interpretation (as I wait and watch them grow) is that our Webmail sucks and we should offer more email storage space. Your interpretation may differ, and your comments are welcome.
In the future, I may want to do comparative analysis with this data. Rather than trust me to not lose it on my hard drive, I'll just link to it from here.
