# PHP-FPM


<img src="https://netdata.cloud/img/php.svg" width="150"/>


Plugin: go.d.plugin
Module: phpfpm

## Overview

This collector monitors PHP-FPM instances.




This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.


### Default Behavior

#### Auto-Detection

This integration doesn't support auto-detection.

#### Limits

The default configuration for this integration does not impose any limits on data collection.

#### Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.


## Metrics

Metrics grouped by *scope*.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.



### Per PHP-FPM instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

| Metric | Dimensions | Unit |
|:------|:----------|:----|
| phpfpm.connections | active, max_active, idle | connections |
| phpfpm.requests | requests | requests/s |
| phpfpm.performance | max_children_reached, slow_requests | status |
| phpfpm.request_duration | min, max, avg | milliseconds |
| phpfpm.request_cpu | min, max, avg | percentage |
| phpfpm.request_mem | min, max, avg | KB |



## Alerts

There are no alerts configured by default for this integration.


## Setup

### Prerequisites

#### Enable status page

Uncomment the `pm.status_path = /status` variable in the `php-fpm` config file.



### Configuration

#### File

The configuration file name for this integration is `go.d/phpfpm.conf`.


You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).

```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/phpfpm.conf
```
#### Options

The following options can be defined globally: update_every, autodetection_retry.

## Troubleshooting

### Debug Mode

To troubleshoot issues with the `phpfpm` collector, run the `go.d.plugin` with the debug option enabled. The output
should give you clues as to why the collector isn't working.

- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.

  ```bash
  cd /usr/libexec/netdata/plugins.d/
  ```

- Switch to the `netdata` user.

  ```bash
  sudo -u netdata -s
  ```

- Run the `go.d.plugin` to debug the collector:

  ```bash
  ./go.d.plugin -d -m phpfpm
  ```
