I am sorry for being less than clear on this. From the DreamHost Wiki:
(emphasis mine). It's not something you can query that database for, and it's not going to be in any standard log that you are likely to have on your computer. It is a *computed" number that they use in profiling MySQL usage.
If you want to do the same, you will need to arrange to count connections and querys, and use the formula already described to determine the "conueries" you are using. "conueries" don't exist until you create (derive) them.
