php-fpm_exporter
A prometheus exporter for PHP-FPM. The exporter connects directly to PHP-FPM and exports the metrics via HTTP.
A webserver such as NGINX or Apache is NOT needed!
Features
- Export single or multiple pools
- Export to CLI as text or JSON
- Connects directly to PHP-FPM via TCP or Socket
- Maps environment variables to CLI options
Usage
php-fpm_exporter
is released as binary and docker image.
It uses sensible defaults which usually avoids the need to use command parameters or environment variables.
php-fpm_exporter
supports 2 commands, get
and server
.
The get
command allows to retrieve information from PHP-FPM without running as a server and exposing an endpoint.
The server
command runs the server required for prometheus to retrieve the statistics.
Options and defaults
Option | Description | Environment variable | Default value |
---|---|---|---|
--web.listen-address |
Address on which to expose metrics and web interface. | PHP_FPM_WEB_LISTEN_ADDRESS |
:9253 |
--web.telemetry-path |
Path under which to expose metrics. | PHP_FPM_WEB_TELEMETRY_PATH |
/metrics |
--phpfpm.scrape-uri |
FastCGI address, e.g. unix:///tmp/php.sock;/status or tcp://127.0.0.1:9000/status | PHP_FPM_SCRAPE_URI |
tcp://127.0.0.1:9000/status |
--log.level |
Only log messages with the given severity or above. Valid levels: [debug, info, warn, error, fatal] (default "error") | PHP_FPM_LOG_LEVEL | info |
CLI Examples
-
Retrieve information from PHP-FPM running on
127.0.0.1:9000
with status endpoint being/status
php-fpm_exporter get
-
Retrieve information from PHP-FPM running on
127.0.0.1:9000
and127.0.0.1:9001
php-fpm_exporter get --phpfpm.scrape-uri tcp://127.0.0.1:9000/status,tcp://127.0.0.1:9001/status
-
Run as server with 2 pools:
php-fpm_exporter server --phpfpm.scrape-uri tcp://127.0.0.1:9000/status,tcp://127.0.0.1:9001/status
Docker Examples
-
Run docker manually
docker pull hipages/php-fpm_exporter docker run -it --rm -e PHP_FPM_SCRAPE_URI="tcp://127.0.0.1:9000/status,tcp://127.0.0.1:9001/status" hipages/php-fpm_exporter
