+;   start time:           01/Jul/2011:17:53:49 +0200
+;   start since:          63087
+;   requests:             12808
+;   request duration:     1250261

+;
+; Note: There is a real-time FPM status monitoring sample web page available
+;       It's available in: /usr/local/share/php/fpm/status.html
+;
+; Note: The value must start with a leading slash (/). The value can be
+;       anything, but it may not be a good idea to use the .php extension or it
+;       may conflict with a real PHP file.
+; Default Value: not set
+;pm.status_path = /status
+
+; The address on which to accept FastCGI status request. This creates a new
+; invisible pool that can handle requests independently. This is useful
+; if the main pool is busy with long running requests because it is still possible
+; to get the status before finishing the long running requests.
+;
+; Valid syntaxes are:
+;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
+;                            a specific port;
+;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
+;                            a specific port;
+;   'port'                 - to listen on a TCP socket to all addresses
+;                            (IPv6 and IPv4-mapped) on a specific port;
+;   '/path/to/unix/socket' - to listen on a unix socket.
+; Default Value: value of the listen option
+;pm.status_listen = 127.0.0.1:9001
+
+; The ping URI to call the monitoring page of FPM. If this value is not set, no
+; URI will be recognized as a ping page. This could be used to test from outside
+; that FPM is alive and responding, or to
+; - create a graph of FPM availability (rrd or such);
+; - remove a server from a group if it is not responding (load balancing);
+; - trigger alerts for the operating team (24/7).
+; Note: The value must start with a leading slash (/). The value can be
+;       anything, but it may not be a good idea to use the .php extension or it
+;       may conflict with a real PHP file.
+; Default Value: not set
+;ping.path = /ping
+
+; This directive may be used to customize the response of a ping request. The
+; response is formatted as text/plain with a 200 response code.
+; Default Value: pong
+;ping.response = pong
+
+; The access log file
+; Default: not set
+;access.log = log/$pool.access.log
+
+; The access log format.
+; The following syntax is allowed
+;  %%: the '%' character
+;  %C: %CPU used by the request
+;      it can accept the following format:
+;      - %{user}C for user CPU only
+;      - %{system}C for system CPU only
+;      - %{total}C  for user + system CPU (default)
+;  %d: time taken to serve the request
+;      it can accept the following format:
+;      - %{seconds}d (default)
+;      - %{milliseconds}d
+;      - %{milli}d
+;      - %{microseconds}d
+;      - %{micro}d
+;  %e: an environment variable (same as $_ENV or $_SERVER)
+;      it must be associated with embraces to specify the name of the env
+;      variable. Some examples:
+;      - server specifics like: %{REQUEST_METHOD}e or %{SERVER_PROTOCOL}e
+;      - HTTP headers like: %{HTTP_HOST}e or %{HTTP_USER_AGENT}e
+;  %f: script filename
+;  %l: content-length of the request (for POST request only)
+;  %m: request method
+;  %M: peak of memory allocated by PHP

+;      - ....
+;  %p: PID of the child that serviced the request
+;  %P: PID of the parent of the child that serviced the request
+;  %q: the query string
+;  %Q: the '?' character if query string exists
+;  %r: the request URI (without the query string, see %q and %Q)
+;  %R: remote IP address
+;  %s: status (response code)
+;  %t: server time the request was received
+;      it can accept a strftime(3) format:
+;      %d/%b/%Y:%H:%M:%S %z (default)
+;      The strftime(3) format must be encapsulated in a %{<strftime_format>}t tag
+;      e.g. for a ISO8601 formatted timestring, use: %{%Y-%m-%dT%H:%M:%S%z}t
+;  %T: time the log has been written (the request has finished)
+;      it can accept a strftime(3) format:
+;      %d/%b/%Y:%H:%M:%S %z (default)
+;      The strftime(3) format must be encapsulated in a %{<strftime_format>}t tag
+;      e.g. for a ISO8601 formatted timestring, use: %{%Y-%m-%dT%H:%M:%S%z}t
+;  %u: remote user
+;
+; Default: "%R - %u %t \"%m %r\" %s"
+;access.format = "%R - %u %t \"%m %r%Q%q\" %s %f %{milli}d %{kilo}M %C%%"
+
+; A list of request_uri values which should be filtered from the access log.
+;
+; As a security precuation, this setting will be ignored if:
+;     - the request method is not GET or HEAD; or
+;     - there is a request body; or
+;     - there are query parameters; or
+;     - the response code is outwith the successful range of 200 to 299
+;
+; Note: The paths are matched against the output of the access.format tag "%r".
+;       On common configurations, this may look more like SCRIPT_NAME than the
+;       expected pre-rewrite URI.
+;
+; Default Value: not set
+;access.suppress_path[] = /ping
+;access.suppress_path[] = /health_check.php
+
+; The log file for slow requests
+; Default Value: not set
+; Note: slowlog is mandatory if request_slowlog_timeout is set
+;slowlog = log/$pool.log.slow
+
+; The timeout for serving a single request after which a PHP backtrace will be
+; dumped to the 'slowlog' file. A value of '0s' means 'off'.
+; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
+; Default Value: 0
+;request_slowlog_timeout = 0
+
+; Depth of slow log stack trace.
+; Default Value: 20
+;request_slowlog_trace_depth = 20
+
+; The timeout for serving a single request after which the worker process will
+; be killed. This option should be used when the 'max_execution_time' ini option
+; does not stop script execution for some reason. A value of '0' means 'off'.
+; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
+; Default Value: 0
+;request_terminate_timeout = 0
+
+; The timeout set by 'request_terminate_timeout' ini option is not engaged after
+; application calls 'fastcgi_finish_request' or when application has finished and
+; shutdown functions are being called (registered via register_shutdown_function).
+; This option will enable timeout limit to be applied unconditionally
+; even in such cases.
+; Default Value: no
+;request_terminate_timeout_track_finished = no
+
+; Set open file descriptor rlimit.
+; Default Value: system defined value
+;rlimit_files = 1024
+
+; Set max core size rlimit.
+; Possible Values: 'unlimited' or an integer greater or equal to 0
+; Default Value: system defined value
+;rlimit_core = 0
+
+; Chroot to this directory at the start. This value must be defined as an
+; absolute path. When this value is not set, chroot is not used.
+; Note: you can prefix with '$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
+;       possible. However, all PHP paths will be relative to the chroot
+;       (error_log, sessions.save_path, ...).
+; Default Value: not set
+;chroot =
+
+; Chdir to this directory at the start.
+; Note: relative path can be used.
+; Default Value: current directory or / when chroot
+;chdir = /var/www
+
+; Redirect worker stdout and stderr into main error log. If not set, stdout and
+; stderr will be redirected to /dev/null according to FastCGI specs.
+; Note: on highloaded environment, this can cause some delay in the page
+; process time (several ms).
+; Default Value: no
+;catch_workers_output = yes
+
+; Decorate worker output with prefix and suffix containing information about
+; the child that writes to the log and if stdout or stderr is used as well as
+; log level and time. This options is used only if catch_workers_output is yes.
+; Settings to "no" will output data as written to the stdout or stderr.
+; Default value: yes
+;decorate_workers_output = no
+
+; Clear environment in FPM workers
+; Prevents arbitrary environment variables from reaching FPM worker processes
+; by clearing the environment in workers before env vars specified in this
+; pool configuration are added.
+; Setting to "no" will make all environment variables available to PHP code
+; via getenv(), $_ENV and $_SERVER.
+; Default Value: yes
+;clear_env = no
+
+; Limits the extensions of the main script FPM will allow to parse. This can
+; prevent configuration mistakes on the web server side. You should only limit
+; FPM to .php extensions to prevent malicious users to use other extensions to
+; execute php code.
+; Note: set an empty value to allow all extensions.
+; Default Value: .php
+;security.limit_extensions = .php .php3 .php4 .php5 .php7
+
+; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
+; the current environment.
+; Default Value: clean env
+;env[HOSTNAME] = $HOSTNAME
+;env[PATH] = /usr/local/bin:/usr/bin:/bin
+;env[TMP] = /tmp
+;env[TMPDIR] = /tmp
+;env[TEMP] = /tmp
+
+; Additional php.ini defines, specific to this pool of workers. These settings
+; overwrite the values previously defined in the php.ini. The directives are the
+; same as the PHP SAPI:
+;   php_value/php_flag             - you can set classic ini defines which can
+;                                    be overwritten from PHP call 'ini_set'.
+;   php_admin_value/php_admin_flag - these directives won't be overwritten by
+;                                     PHP call 'ini_set'
+; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
+
+; Defining 'extension' will load the corresponding shared extension from
+; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
+; overwrite previously defined php.ini values, but will append the new value
+; instead.
+
+; Note: path INI options can be relative and will be expanded with the prefix
+; (pool, global or /usr/local)
+
+; Default Value: nothing is defined by default except the values in php.ini and
+;                specified at startup with the -d argument
+;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
+php_flag[display_errors] = off
