Hi Tony,
Wow, that looks great! Your screengrab is fairly low resolution (when posting, change the default 500 pixels in the post-editor-pic-uploader to 1000) but I see you've developed some more queries e.g. users locked out, and some stats across the top with nice icons. Would you care to elaborate what statistics you are finding useful to have, and also perhaps share the SQL behind these please?
I'm sure everyone here would really enjoy building a library of SQL queries; I am also particularly interested in what stats you are finding useful to see in your NOC...
