Prometheus Exporter for the PHP-FPM status page.
Metrics are scrapped via unix socket and made available on port 9253.
This exporter also provides a way for embedding the output of arbitrary
PHP scripts into its metrics page, analogous to the node exporter's
textfile collector. Scripts that are specified with the
--phpfpm.script-collector-paths flag will be run through PHP-FPM. Any
metrics printed by the PHP script will be merged into the metrics
provided by this exported. An example use case includes printing metrics
for PHP's opcache.
Running exporter
./phpfpm_exporter --phpfpm.socket-paths /var/run/phpfpm.sock --phpfpm.script-collector-paths /path/script.php
Help on flags
./phpfpm_exporter -h
usage: phpfpm_exporter [<flags>]
Flags:
-h, --help Show context-sensitive help (also try --help-long and --help-man).
--web.listen-address=":9253"
Address to listen on for web interface and telemetry.
--web.telemetry-path="/metrics"
Path under which to expose metrics.
--phpfpm.socket-paths=PHPFPM.SOCKET-PATHS ...
Path(s) of the PHP-FPM sockets.
--phpfpm.socket-directories=PHPFPM.SOCKET-DIRECTORIES ...
Path(s) of the directory where PHP-FPM sockets are located.
--phpfpm.status-path="/status"
Path which has been configured in PHP-FPM to show status page.
--version Print version information.
--phpfpm.script-collector-paths=PHPFPM.SCRIPT-COLLECTOR-PATHS ...
Paths of the PHP file whose output needs to be collected.
When using --phpfpm.socket-directories make sure to use dedicated directories for PHP-FPM sockets to avoid timeouts.
