On LAMP production server I get the 'too many connections' error from MYSQL occasionally, I want to add monitoring to find if the reason is that I exceed the max-connections limit.

My question: How can I query from mysql or from mysqladmin the current number of used connections? (I noticed that show status gives total connections and not the currently used ones.)
