# getifaddrs
Plugin: freebsd.plugin
Module: getifaddrs
## Overview
Collect traffic per network interface.
The plugin calls `getifaddrs` function to collect necessary data.
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 getifaddrs instance
General overview about network traffic.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| system.net | received, sent | kilobits/s |
| system.packets | received, sent, multicast_received, multicast_sent | packets/s |
| system.ipv4 | received, sent | kilobits/s |
| system.ipv6 | received, sent | kilobits/s |
### Per network device
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| net.net | received, sent | kilobits/s |
| net.packets | received, sent, multicast_received, multicast_sent | packets/s |
| net.errors | inbound, outbound | errors/s |
| net.drops | inbound, outbound | drops/s |
| net.events | collisions | events/s |
## Alerts
The following alerts are available:
| Alert name | On metric | Description |
|:------------|:----------|:------------|
| [ interface_speed ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.net | network interface ${label:device} current speed |
| [ inbound_packets_dropped_ratio ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.drops | ratio of inbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| [ outbound_packets_dropped_ratio ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.drops | ratio of outbound dropped packets for the network interface ${label:device} over the last 10 minutes |
| [ 1m_received_packets_rate ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.packets | average number of packets received by the network interface ${label:device} over the last minute |
| [ 10s_received_packets_storm ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.packets | ratio of average number of received packets for the network interface ${label:device} over the last 10 seconds, compared to the rate over the last minute |
| [ interface_inbound_errors ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.errors | number of inbound errors for the network interface ${label:device} in the last 10 minutes |
| [ interface_outbound_errors ](https://github.com/netdata/netdata/blob/master/health/health.d/net.conf) | net.errors | number of outbound errors for the network interface ${label:device} in the last 10 minutes |
## Setup
### Prerequisites
No action required.
### Configuration
#### File
The configuration file name for this integration is `netdata.conf`.
Configuration for this specific integration is located in the `[plugin:freebsd:getifaddrs]` section within that file.
The file format is a modified INI syntax. The general structure is:
```ini
[section1]
option1 = some value
option2 = some other value
[section2]
option3 = some third value
```
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 netdata.conf
```
