This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

PHP-FPM server status metrics collected from PHP-FPM.

php_fpm Fieldsedit

php_fpm contains the metrics that were obtained from PHP-FPM status page call.

pool Fieldsedit

pool contains the metrics that were obtained from the PHP-FPM process pool.


type: keyword

The name of the pool.

connections Fieldsedit

Connection state specific statistics.


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.


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.

processes Fieldsedit

Process state specific statistics.


type: long

The number of servers in the waiting to process state (i.e. not currently serving a page). This value should fall between the pm.min_spare_servers and pm.max_spare_servers values when the process manager is dynamic.


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 read 0).


type: long

The number of times a request execution time has exceeded request_slowlog_timeout.
