|
|
|
A [prometheus](https://prometheus.io/) 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](https://github.com/hipages/php-fpm_exporter/releases) and [docker](https://hub.docker.com/r/hipages/php-fpm_exporter/) 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`](https://github.com/prometheus/prometheus/wiki/Default-port-allocations) |
|
|
| `--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` |
|
|
|
|
### 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` and `127.0.0.1:9001`
|
|
|
|
```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
|
|
|
|
* 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
|
|
|
|
