PHP-FPM server status metrics collected from PHP-FPM.
php_fpm fields
editphp_fpm
contains the metrics that were obtained from PHP-FPM status page call.
pool fields
editpool
contains the metrics that were obtained from the PHP-FPM process pool.
-
php_fpm.pool.name
-
type: keyword
The name of the pool.
-
php_fpm.pool.process_manager
-
type: keyword
Static, dynamic or ondemand.
connections fields
editConnection state specific statistics.
-
php_fpm.pool.connections.accepted
-
type: long
The number of incoming requests that the PHP-FPM server has accepted; when a connection is accepted it is removed from the listen queue.
-
php_fpm.pool.connections.queued
-
type: long
The current number of connections that have been initiated, but not yet accepted. If this value is non-zero it typically means that all the available server processes are currently busy, and there are no processes available to serve the next request. Raising
pm.max_children
(provided the server can handle it) should help keep this number low. This property follows from the fact that PHP-FPM listens via a socket (TCP or file based), and thus inherits some of the characteristics of sockets. -
php_fpm.pool.connections.max_listen_queue
-
type: long
The maximum number of requests in the queue of pending connections since FPM has started.
-
php_fpm.pool.connections.listen_queue_len
-
type: long
The size of the socket queue of pending connections.
processes fields
editProcess state specific statistics.
-
php_fpm.pool.processes.idle
-
type: long
The number of servers in the
waiting to process
state (i.e. not currently serving a page). This value should fall between thepm.min_spare_servers
andpm.max_spare_servers
values when the process manager isdynamic
. -
php_fpm.pool.processes.active
-
type: long
The number of servers current processing a page - the minimum is
1
(so even on a fully idle server, the result will be not read0
). -
php_fpm.pool.processes.total
-
type: long
The number of idle + active processes.
-
php_fpm.pool.processes.max_active
-
type: long
The maximum number of active processes since FPM has started.
-
php_fpm.pool.processes.max_children_reached
-
type: long
Number of times, the process limit has been reached, when pm tries to start more children (works only for pm dynamic and ondemand).
-
php_fpm.pool.slow_requests
-
type: long
The number of times a request execution time has exceeded
request_slowlog_timeout
. -
php_fpm.pool.start_since
-
type: long
Number of seconds since FPM has started.
-
php_fpm.pool.start_time
-
type: date
format: epoch_second
The date and time FPM has started.
