PHP_FPM fields
Elastic Cloud Serverless projects are autoscaled environments, fully managed by Elastic and available on Elastic Cloud. Availability This functionality is generally available and ready for production usage. Serverless interfaces and procedures might differ from classic Elastic Stack deployments. The Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats. Availability This functionality is generally available and ready for production usage. Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.

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
type: integer
