-; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
-; This value sets the limit on the number of simultaneous requests that will be
-; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
-; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
-; CGI. The below defaults are based on a server without much resources. Don't
-; forget to tweak pm.* to fit your needs.
-; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
-; Note: This value is mandatory.
-pm.max_children = 5
-
-; The number of child processes created on startup.
-; Note: Used only when pm is set to 'dynamic'
-; Default Value: (min_spare_servers + max_spare_servers) / 2
-pm.start_servers = 2
-
-; The desired minimum number of idle server processes.
-; Note: Used only when pm is set to 'dynamic'

-pm.max_spare_servers = 3
-
-; The number of seconds after which an idle process will be killed.
-; Note: Used only when pm is set to 'ondemand'
-; Default Value: 10s
-;pm.process_idle_timeout = 10s;
-
-; The number of requests each child process should execute before respawning.
-; This can be useful to work around memory leaks in 3rd party libraries. For
-; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
-; Default Value: 0
-;pm.max_requests = 500
-
-; The URI to view the FPM status page. If this value is not set, no URI will be
-; recognized as a status page. It shows the following informations:
-;   pool                 - the name of the pool;
-;   process manager      - static, dynamic or ondemand;
-;   start time           - the date and time FPM has started;
-;   start since          - number of seconds since FPM has started;
-;   accepted conn        - the number of request accepted by the pool;
-;   listen queue         - the number of request in the queue of pending
-;                          connections (see backlog in listen(2));
-;   max listen queue     - the maximum number of requests in the queue
-;                          of pending connections since FPM has started;
-;   listen queue len     - the size of the socket queue of pending connections;
-;   idle processes       - the number of idle processes;
-;   active processes     - the number of active processes;
-;   total processes      - the number of idle + active processes;
-;   max active processes - the maximum number of active processes since FPM
-;                          has started;
-;   max children reached - number of times, the process limit has been reached,
-;                          when pm tries to start more children (works only for
-;                          pm 'dynamic' and 'ondemand');
-; Value are updated in real time.
-; Example output:
-;   pool:                 www
-;   process manager:      static
-;   start time:           01/Jul/2011:17:53:49 +0200
-;   start since:          62636
-;   accepted conn:        190460
-;   listen queue:         0
-;   max listen queue:     1
-;   listen queue len:     42
-;   idle processes:       4
-;   active processes:     11
-;   total processes:      15
-;   max active processes: 12
-;   max children reached: 0
-;
-; By default the status page output is formatted as text/plain. Passing either
-; 'html', 'xml' or 'json' in the query string will return the corresponding
-; output syntax. Example:
-;   http://www.foo.bar/status
-;   http://www.foo.bar/status?json
-;   http://www.foo.bar/status?html
-;   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
-; The Full status returns for each process:
-;   pid                  - the PID of the process;
-;   state                - the state of the process (Idle, Running, ...);
-;   start time           - the date and time the process has started;
-;   start since          - the number of seconds since the process has started;
-;   requests             - the number of requests the process has served;
-;   request duration     - the duration in µs of the requests;
-;   request method       - the request method (GET, POST, ...);
-;   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 informations are related to the
-; last request the process has served. Otherwise informations are related to
-; the current request being served.
-; Example output:

-;   pid:                  31330

-; 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

-
-; 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.

-; 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)
-
-; 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
