PHP-FPM server status metrics collected from PHP-FPM.
php_fpm contains the metrics that were obtained from PHP-FPM status page call.
pool contains the metrics that were obtained from the PHP-FPM process pool.
-
php_fpm.pool.name -
The name of the pool.
type: keyword
pool contains the metrics that were obtained from the PHP-FPM process pool.
-
php_fpm.pool.process_manager -
Static, dynamic or ondemand.
type: keyword
Connection state specific statistics.
-
php_fpm.pool.connections.accepted -
The number of incoming requests that the PHP-FPM server has accepted; when a connection is accepted it is removed from the listen queue.
type: long
-
php_fpm.pool.connections.queued -
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.type: long
-
php_fpm.pool.connections.max_listen_queue -
The maximum number of requests in the queue of pending connections since FPM has started.
type: long
-
php_fpm.pool.connections.listen_queue_len -
The size of the socket queue of pending connections.
type: long
Process state specific statistics.
-
php_fpm.pool.processes.idle -
The number of servers in the
waiting to processstate (i.e. not currently serving a page). This value should fall between thepm.min_spare_serversandpm.max_spare_serversvalues when the process manager isdynamic.type: long
-
php_fpm.pool.processes.active -
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).type: long
-
php_fpm.pool.processes.total -
The number of idle + active processes.
type: long
-
php_fpm.pool.processes.max_active -
The maximum number of active processes since FPM has started.
type: long
-
php_fpm.pool.processes.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).
type: long
-
php_fpm.pool.slow_requests -
The number of times a request execution time has exceeded
request_slowlog_timeout.type: long
-
php_fpm.pool.start_since -
Number of seconds since FPM has started.
type: long
-
php_fpm.pool.start_time -
The date and time FPM has started.
type: date
process contains the metrics that were obtained from the PHP-FPM process.
-
php_fpm.process.pid -
The PID of the process
type: alias
alias to: process.pid
-
php_fpm.process.state -
The state of the process (Idle, Running, etc)
type: keyword
-
php_fpm.process.start_time -
The date and time the process has started
type: date
-
php_fpm.process.start_since -
The number of seconds since the process has started
type: integer
-
php_fpm.process.requests -
The number of requests the process has served
type: integer
-
php_fpm.process.request_duration -
The duration in microseconds (1 million in a second) of the current request (my own definition)
type: integer
-
php_fpm.process.request_method -
The request method (GET, POST, etc) (of the current request)
type: alias
alias to: http.request.method
-
php_fpm.process.request_uri -
The request URI with the query string (of the current request)
type: alias
alias to: url.original
-
php_fpm.process.content_length -
The content length of the request (only with POST) (of the current request)
type: alias
alias to: http.response.body.bytes
-
php_fpm.process.user -
The user (PHP_AUTH_USER) (or - if not set) (for the current request)
type: alias
alias to: user.name
-
php_fpm.process.script -
The main script called (or - if not set) (for the current request)
type: keyword
-
php_fpm.process.last_request_cpu -
The CPU percentage 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
type: long
-
php_fpm.process.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
