  181. ; user - the user (PHP_AUTH_USER) (or '-' if not set);
  182. ; script - the main script called (or '-' if not set);
  183. ; last request cpu - the %cpu the last request consumed
  184. ; it's always 0 if the process is not in Idle state
  185. ; because CPU calculation is done when the request
  186. ; processing has terminated;
  187. ; last request memory - the max amount of memory the last request consumed
  188. ; it's always 0 if the process is not in Idle state
  189. ; because memory calculation is done when the request
  190. ; processing has terminated;
  191. ; If the process is in Idle state, then informations are related to the
