+
+; The URI to view the FPM status page. If this value is not set, no URI will be

+; By default the status page output is formatted as text/plain. Passing either

+;   http://www.foo.bar/status?xml
+;
+; By default the status page only outputs short status. Passing 'full' in the
+; query string will also return status for each pool process.
+; Example:
+;   http://www.foo.bar/status?full
+;   http://www.foo.bar/status?json&full
+;   http://www.foo.bar/status?html&full
+;   http://www.foo.bar/status?xml&full

+;   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
+;                          processing has terminated;
+;   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
+;                          processing has terminated;
+; If the process is in Idle state, then information is related to the
+; last request the process has served. Otherwise information is related to

+; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
+; of its subdirectories. If the pool prefix is not set, the global prefix
+; will be used instead.
+; Note: chrooting is a great security feature and should be used whenever
