# net.inet.udp.stats
<img src="https://netdata.cloud/img/network.svg" width="150"/>
Plugin: freebsd.plugin
Module: net.inet.udp.stats
<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
## Overview
Collect information about UDP connections.
The plugin calls `sysctl` 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 net.inet.udp.stats instance
These metrics show UDP connections statistics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| ipv4.udppackets | received, sent | packets/s |
| ipv4.udperrors | InErrors, NoPorts, RcvbufErrors, InCsumErrors, IgnoredMulti | events/s |
## Alerts
The following alerts are available:
| Alert name | On metric | Description |
|:------------|:----------|:------------|
| [ 1m_ipv4_udp_receive_buffer_errors ](https://github.com/netdata/netdata/blob/master/src/health/health.d/udp_errors.conf) | ipv4.udperrors | average number of UDP receive buffer errors over the last minute |
| [ 1m_ipv4_udp_send_buffer_errors ](https://github.com/netdata/netdata/blob/master/src/health/health.d/udp_errors.conf) | ipv4.udperrors | average number of UDP send buffer errors over the last minute |
## 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:net.inet.udp.stats]` 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](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf
```
#### Options
<details open><summary>Config options</summary>
| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| ipv4 UDP packets | Enable or disable ipv4 UDP packets metric. | yes | no |
| ipv4 UDP errors | Enable or disable ipv4 UDP errors metric. | yes | no |
</details>
#### Examples
There are no configuration examples.
