+; request URI - the request URI with the query string;
|
|
|
+; content length - the content length of the request (only with POST);
|
|
|
+; user - the user (PHP_AUTH_USER) (or '-' if not set);
|
|
|
+; script - the main script called (or '-' if not set);
|
|
|
+; last request cpu - the %cpu the last request consumed
|
|
|
+; it's always 0 if the process is not in Idle state
|
|
|
+; because CPU calculation is done when the request
|
|
|

|
|
|
+; last request memory - the max amount of memory the last request consumed
|
|
|
+; it's always 0 if the process is not in Idle state
|
|
|
+; because memory calculation is done when the request
|
|
|

|
|
|
+; If the process is in Idle state, then informations are related to the
